The storeAlert command will retrieve the message from the alert popup and store it in a variable.

24) What is RC (Remote Control) selenium?

In terms of browser support and language support, Selenium IDE has several restrictions. RC restriction can be reduced by utilising Selenium.

For automating web applications, selenium RC is used with languages such as Java, C#, Perl, and Python on various platforms and web browsers.

Selenium RC is a java-based tool that can communicate with a web application in any language.

You can get around the restriction by using server to run your automation script against any web application.

25) What is the purpose of Selenium RC?

Many functionalities, like as condition statements, iteration, logging, and so on, are not directly supported by Selenium IDE. Because the IDE only supports HTML, it can't do things like report test results or handle unexpected errors. To deal with such problems, Selenium RC is utilised, and it supports languages such as Perl, Ruby, Python, and PHP. We can develop programmes in these languages to solve IDE concerns.

Selenium Interview Question and Answers

Selenium Interview Question and Answers

1) What is an Object Repository, and how does it work?

An object repository is a critical component of any UI automation since it allows a tester to keep all of the objects that will be utilised in the scripts in one or more centralised locations rather than scattering them throughout the test scripts.

2) What is the Selenium Grid and how does it work?

The tests were delivered to the hub by Selenium Grid. These tests are routed through Selenium Webdriver, which opens the browser and runs the test. It is possible to run tests in parallel using the whole test suite.

3) Is Selenium grid suitable for performance testing?

Yes. However, it does not perform as well as a specialised Performance Testing tool such as Loadrunner.

4) What are the benefits of using Webdriver instead of Selenium Server?

You don't require the Selenium-WebDriver plugin if you're using Selenium-WebDriver.

Selenium Server is unique in that it use a completely separate technology.

Selenium Server has Selenium RC capabilities, which is needed for backwards compatibility with Selenium 1.0.

Selenium Web driver provides direct calls to browsers, taking advantage of each browser's inherent automation functionality, whereas Selenium RC relies on the selenium server injecting Javascript into the browser.

5) What capabilities does Selenium WebDriver or Selenium 2.0 have?

When you need better support for something, WebDriver is the way to go.

Multiple frames, pop-ups, browser windows, and notifications to manage
Page navigation and Ajax-based UI elements that can be dragged and dropped
Multi-browser testing, including better capability for Selenium 1.0 browsers that aren't well supported

6) What are the limitations that can be encountered while inserting capabilities in webdriver to execute tests on a browser that is not supported by a webdriver?

The "findElement" command may not perform as expected, which is a major limitation of injecting capabilities.

7) How can you use the Selenium Web driver to discover damaged images on a page?

The Selenium web driver can be used to find broken images on a page.

Get XPath and use tag name to get all the links on the page.
Click on each and every link on the page.

8) Look for the words 404/500 in the title of the destination page. How do you handle colours in a web driver?

You can use the web driver to handle colours.

By passing the 'colour' string as an argument to the getCssValue(arg0) method, you can get the colours.

9) How do you store a value in a text box using a web driver?

You can use the web driver to store a value in a text box by using the following command.

findElement(By.id("your Textbox")); driver.findElement(By.id("your Textbox")); driver.findElement(By.

sendKeys("your keyword"); sendKeys("your keyword"); sendKeys("your keyword

10) Can you explain how you can change frames?

The [driver.switchTo().frame()] method in webdrivers takes one of three arguments to switch between frames.

a figure: It chooses the number based on

according to its (zero-based) index

A name or identification number: Choose a frame based on its name or ID.

Previously discovered WebElement: Select a frame using the previously discovered WebElement.

11) Describe five different Selenium web driver exceptions.

You had five separate exceptions with Selenium web drivers.

WebDriverException
NoAlertPresentException
NoSuchWindowException
NoSuchElementException
TimeoutException

12) Explain how to perform a double click using Webdriver.

Using the mouse, you can do a double click.

Act = new Actions (driver); act.doubleClick(webelement);

13) Syntax- Actions act = new Actions (driver); act.doubleClick(webelement); How will you upload a file with Selenium?

You can enter in a file input box of an upload file using the "type" command. Then, to make file upload work, you must use JAVA's "Robot" class.

14) Which implementation of a web driver is the quickest?

HTMLUnitDriver's implementation is the quickest; HTMLUnitDriver does not run tests in the browser but instead sends a plain http request, which is far faster than opening a browser and running tests.

15) Can you explain how you can use Selenium 2.0 to manage frames?

You can use the "SwitchTo" frame technique to get control over an HTML frame.

driver.switchTo().frame(“frameName”);

To specify a frame you can use index number

driver.switchTo().frame(“parentFrame.4.frameName”);

This would bring control on frame named- “frameName” of the 4th sub frame names “parentFrame”

16) What is the difference between getWindowhandles() and getwindowhandle() ?

getwindowhandles(): It is used to get the address of all the open browser and its return type is Set<String>

getwindowhandle(): It is used to get the address of the current browser where the control is and return type is string

17) Explain how you can switch back from a frame?

To switch back from a frame use method defaultContent()

Syntax-driver.switchTo().defaultContent();

18) What are the many sorts of locators?

There are various sorts of locators.

By.id()

By.name()

By.tagName()

By.className()

By.linkText()

By.partialLinkText()

By.xpath

By.cssSelector()

19) In order to display the values of a variable in the output console or log, what command is used?

echo is a command that can be used to display a constant string.

You can use commands like echo $variable name>> to display the value of a variable.

PHP is used in the example above. Replace echo with System.out if you're using Java. println

20) Can you explain how you can use Selenium's recovery scenario?

The type of recovery scenario you utilise is determined on the programming language you use. If you're using Java, you can use exception handling to get around the problem. Using the "Try Catch Block" option within Java testing using Selenium WebDriver

In Python, indentation is required. Because it doesn't utilize curly braces, you'll need to indent code blocks evenly so that it knows what belongs in a block and what doesn't. This is a mistake:

Q.2 What does PEP 8 stand for?

The Python Enhancement Proposal 8 (PEP) is a Python-style guide. It includes coding rules and recommendations to assist make code more readable and consistent. Indentation, line length, blank lines, source file encoding, imports, string quotes, whitespace, trailing commas, comments, and docstrings, naming standards, and some programming advice are all included.

Q.3 What is the purpose of the zip() function?

This function combines objects by mapping related indices of several objects. After that, it returns a zip object. This is how it works:

Q.4. What is the purpose of the swap case() function?

The str class has a swap case() function that transforms uppercase to lowercase and vice versa.

Q.5. Can you shuffle 10 cards in your hands ([2,4,7,8,9, J, Q, K, A, A]) with Python?

Here, we'll use the random module's shuffle() method. This method shuffles a list while it is still in place.

Q.6. Which Python module will you use if you wish to work with files?

Python includes the following options for dealing with text and binary files:

shutil os (and os.path)
You can use them to create a file, duplicate its contents, and remove it.

Q.7. Does Python offer a variety of file processing modes?

You can open files in four different modes with Python: read-only, write-only, read-write, and add.

Only read mode is available. ('r') – Open a file in default mode for reading.
Open a file for writing, replace any contents, or create a new file in write-only mode ('w').
'rw' stands for read-write mode. - Open a file that needs to be updated.
Append mode ('a') – adds a new line to the end of the file.

Q.8. What is the difference between Python 2.x and Python 3.x?

Python 2 and 3 are similar yet differ slightly:

The print() function in Python 3 replaces the print statement in Python 2.
Strings in Python 3 are Unicode by default. Strings in Python 2 are ASCII.
Some Python 3 libraries are incompatible with Python 2.
For input, Python 2 had a raw input() method. The xrange() function was also included.
Python 2 will be deprecated on January 1, 2020; legacy Python 2 programs can be converted to Python 3 by then.
In Python 2, division returns an integer, whereas in Python 3, it returns a float.

Q.9. What is the purpose of enumerating ()?

This function iterates through a sequence and gets the index position and value for each item.

Q.10: What does PYTHONPATH stand for?

This is a comparable environment variable to PATH. The interpreter looks for a module at the address provided by this variable whenever you import it. It extends the usual module file search path. The value of this variable is a string containing a directory list for the sys.path directory list. One good application of this is to import our code that isn't yet available as an installable package.

Q.11 What is the difference between PYTHONSTARTUP, PYTHONCASEOK, and PYTHONHOME?

PYTHONSTARTUP is a variable that stores the path of an initialization file containing Python code. Before the first prompt appears, this executes every time you start the interpreter.

Python ignores cases in import statements if PYTHONCASEOK is set. This only applies to Windows and Mac OS X. To

After you've activated it, you can change the value to whatever you like.

PYTHONHOME, on the other hand, modifies the location of the standard Python libraries.

On Windows, go to System Properties and then to Environment Variables to do this. Add a new Environment Variable and its value after that.

Q.12 What distinguishes lists from tuples?

In Python, there are two data types: lists and tuples, both of which are collections of objects. But they're not the same, and here's why:

Tuples are immutable, whereas lists are mutable. A list can be changed, but not a tuple.

Tuples are faster than lists.
Because tuples are immutable, they can be used as dictionary keys; lists cannot because they are mutable.
A tuple cannot be sorted, but we can sort a list with sort ().

Q.13. How do you get rid of the last item in a list?

Consider the following list of three items: [1,2,3]. This is how we can get rid of the last object:

Q.14. Describe the Python map() function.

This function creates an iterator that computes the function using arguments from each iterable. This, like zipping (), exhausts the shortest iterable.

Q.15. In Python, what is __init__?

In C++, __init__ is a magic method that works similarly to a function Object() { [native code] }. It's used to set up new items. This function is called whenever a new object is created, and it allocates memory for the new object. Python will use its default version if you don't provide a __init__ for a class.

Q.16.Is Python entirely object-oriented?

In Python, everything is an object. It isn't fully object-oriented, though, because it doesn't enable strong encapsulation, which is the packaging of data with methods and limiting access to some of them.

Q.17.What is loop interruption, and how does it work?

Interrupting a loop involves ending it before it has completed all of its iterations. There are three loop interruption statements in Python:

break — This exits the loop and executes the next statement in the sequence.

continue — Skips to the next iteration without performing the previous statements.

pass – When you don't know what to put in a loop, use this.

Q.18.Is Python a pass-by-value or pass-by-reference language?

Python does not support both pass-by-value and pass-by-reference. It's a pass-by-object-reference pass-through. This means that modifications to a mutable object supplied to a function will impact the original, whereas changes to an immutable object passed to a function would not.

Q.19.What is a namespace, exactly?

A name is a unique identifier (a name we use to refer to someone giving to things). A collection of names is referred to as a namespace. This is a list of all the names and the objects they identify. Multiple namespaces can be used to avoid name collisions. Even when we call a function, it creates a local namespace that contains all of the names.

Q.20. In Python, what is percent s?

We can embed values in strings with Python. F-strings, the format() method, and the percent operator are the three options. You can use it in the following way:

WebDriver and RC are APIs for a range of languages, including Java,.NET, PHP, and others. Webdriver and RC are compatible with the majority of browsers.

Grid: Grid allows you to distribute tests over numerous machines so that they may be run in parallel, reducing the amount of time it takes to run browser test suites.

2. What is Selenium 2.O?

Web Testing tools Selenium RC and WebDriver are consolidated in single tool in Selenium 2.0

3) How do you plan on using Selenium to locate an element?

Every object or control in a web page is referred to as an element in Selenium, and there are several ways to locate one.

Name

Tag

Attribute

CSS

Text

Xpath

Linktext

PartialLink

4) What are the different kinds of tests that Selenium supports?

Selenium is a tool that can be used to test web-based applications.

The following are examples of test kinds that can be accommodated.

a) It is useful; More information on functional testing can be found here.

egression is the second option.

An automated continuous integration tool could be utilised for post-release validation.

Jenkins, to begin with

Hudson,

Simple to construct

CruiseCont

5) Describe what assertion is in Selenium and the different sorts of assertion.

Assertion is used as a point of verification. It confirms that the application's current status is as intended. "assert," "verify," and "waitFor" are the three sorts of assertions.

6) What is the purpose of the X-path?

In web pages, X-Path is utilised to locate the WebElement. It can also be used to identify dynamic aspects.

Refer to the XPath Complete Guide.

7) In X-path, what is the difference between a single and a double slash?

'/' is a single slash.

Start selection from the document node with a single slash (/).
You can use it to make 'absolute' path expressions.
'//' with a double slash

Start selection matching anywhere in the document with a double slash (/).
It allows you to make path expressions that are'relative.'

8.What are the technological difficulties using Selenium?

Selenium has a number of technical challenges.

Only web-

based applications are supported by Selenium.

The Bitmap comparison is not supported.

Any reporting-related functions must rely on third-party software.

In comparison to commercial products like HP UFT, the tool has no vendor support.

Maintainability of objects becomes problematic in Selenium since there is no concept of an object repository.

9.What is the difference between keyboard shortcuts and keyboard commands?

In most circumstances, TypeKeys() will produce a JavaScript event, whereas.type() would not.

Type key uses JavaScript to populate the value attribute, whereas.typekeys() simulates actual user typing.

10.What is the difference between the commands verify and assert?

Assert: Assert allows you to see if an element is present on the page.

or it's not. If the asserted element is not available, the test will fail at that step. To put it another way, the test will end when the check fails.

Verify: The verify command checks whether the element is present on the page; if it is not, the test will continue to run. Even if one of the tests fails, all of the commands will be guaranteed to run during verification.

11) What are JUnit Annotations and what are the different sorts of annotations?

Annotations are a unique type of syntactic meta-data that can be introduced to Java source code. Annotated variables, parameters, packages, methods, and classes Some of the more helpful Junit annotations are:

Test
Before
After
Ignore
BeforeClass
AfterClass
RunWith

12) Is it possible to use screen coordinates while using the click command?

You'll need to use the clickAT command to click on a specific area of an element. The element locator and x, y co-ordinates are passed as arguments to the ClickAt instruction.

13) What are some of the benefits of selenium?

C#, PHP, Java, Perl, and Phython are all supported.
It works with a variety of operating systems, including Windows, Linux, and Mac OS.
It has effective methods for locating components (Xpath, DOM , CSS)
It has a large development community that is backed by Google.

14) Why should testers use Selenium instead of QTP?

Selenium is more widely used than QTP.

QTP is a commercial tool, whereas Selenium is open source.
Selenium is used to test web-based applications, whereas QTP can be used to test client-server applications. Selenium supports Firefox, Internet Explorer, Opera, and Safari on operating systems such as Windows, Mac, and Linux, whereas QTP is confined to Internet Explorer on Windows.
Selenium supports a variety of programming languages, including Ruby, Perl, and Python, whereas QTP does not.

Java Interview Questions and Answers

Java Interview Questions and Answers

1. What makes Java a platform-agnostic language?
Because the compiler compiles the code and then converts it to platform-independent byte code that can be run on many platforms, the Java language was designed to be independent of any hardware or software.

The sole need for running the byte code is that the machine is equipped with a Java runtime environment (JRE).

2. What makes Java different from other object-oriented languages?
Java is not a pure object-oriented language because it supports primitive data types such as byte, boolean, char, short, int, float, long, and double.

3. In Java, what is the difference between heap and stack memory? And how Java makes use of it.
Stack memory is a type of memory that is used to store data. Each program was given a certain amount of memory. And the problem was resolved. Heap memory, on the other hand, is the piece of memory that was not allocated to the java program but will be accessible for use by the java program when it is needed, which is usually during the program's runtime.

4. Can java be described as an object-oriented programming language in its entirety?
If we say that java is the entire object-oriented programming language, we are not wrong. Because classes are the foundation of Java. We can gain access to this by constructing objects.

However, because it supports primitive data types such as int, float, char, boolean, double, and others, we can claim that java is not a fully object-oriented programming language.

Is Java an entirely object-oriented programming language? Because it allows direct access to primitive data types, we can say that Java is not a pure object-oriented programming language. Furthermore, these primitive data types are not directly related to the Integer classes.

5. What distinguishes Java from C++?
Java is both a compiled and an interpreted language, whereas C++ is solely a compiled language.
Java applications run on any machine, whereas C++ programs can only execute on the machine where they were compiled.
In C++, users can use pointers in their programs. Java, on the other hand, does not enable it. Internally, Java makes use of pointers.
Multiple inheritances are supported in C++, however, they are not supported in Java. The diamond dilemma arises from the need to avoid the complexities of name ambiguity.

6. In C/C++, pointers are used. Why is it that Java doesn't use pointers?
Beginner programmers should avoid using pointers because they are fairly difficult. The use of pointers might be useful in Java because it focuses on code simplicity.

Make it difficult. The use of a pointer might also lead to mistakes. Furthermore, when pointers are utilized, security is undermined since pointers allow people to directly access memory.

By not including pointers in Java, a certain amount of abstraction is provided. Furthermore, the use of pointers might make garbage collection time-consuming and inaccurate. References are used in Java because, unlike pointers, they cannot be changed.

7. Can you explain what an instance variable and a local variable are?
Instance variables are variables that are available to all of the class's methods. They are declared both outsides and inside the methods. These variables describe an object's attributes and are inextricably linked to it.

All of the class's objects will have a copy of the variables to use. If any changes are made to these variables, just that instance will be affected, while all other class instances would stay unchanged.

8. In Java, what are the default values for variables and instances?
In Java, no default values are assigned to variables. Before we can use the value, we must first initialize it. Otherwise, a compilation error will be thrown (the Variable might not be initialized).
However, if we build the object, the default value will be set by the default function Object() { [native code] }, which will be determined by the data type.
If the value is a reference, it will be set to null.
If it's a number, it'll be assigned to 0.
If the value is a boolean, it will be set to false.

9. What exactly do you mean when you say "data encapsulation"?
Data encapsulation is an Object-Oriented Programming paradigm that encapsulates data properties and behaviors into a single unit.
It aids developers in adhering to modularity when designing software by ensuring that each object is self-contained, with its methods, characteristics, and functionalities.
It is used to protect an object's private properties and so serves the aim of data concealing.

10. Tell us about the JIT compiler.
JIT stands for Just-In-Time, and it is a performance optimization technique that is used to improve efficiency during runtime. Its job is to compile bits of byte code with similar functionality at the same time, minimizing the amount of time the code takes to compile and run.
The compiler is nothing more than a tool for converting source code into machine-readable code. But what makes the JIT compiler unique? Let's take a look at how it works:
The javac compiler is used to convert Java source code (.java) to byte code (.class) for the first time.
The. class files are then loaded by JVM at runtime and translated to machine-readable code with the help of an interpreter.
The JIT compiler (just-in-time compiler) is a component of the JVM When the JIT compiler is enabled, the JVM analyses and compiles method calls in.class files to produce more efficient and native code. It also ensures that the method calls that are prioritized are optimized.
After completing the preceding step, the JVM executes the optimized code directly rather than reinterpreting it. This improves the execution's efficiency and speed.

10. Describe function Object() { [native code] } overloading in a few words.

Constructor overloading is the process of creating numerous constructors with the same name but different function Object() { [native code] } parameters in the same class. The compiler distinguishes the different types of constructors based on the number of parameters and their related types.

11. How is an infinite loop declared in Java?

Infinite loops are those loops that run infinitely without any breaking conditions. Some examples of consciously declaring an infinite loop are:

Using For Loop:
for (;;)
{
// Business logic
// Any break logic
}
Using while loop:
while(true){
// Business logic
// Any break logic
}
Using the do-while loop:
do{
// Business logic
// Any break logic
}while(true);

13. Briefly explain the concept of constructor overloading
Constructor overloading is the process of creating multiple constructors in the class consisting of the same name with a difference in the constructor parameters. Depending upon the number of parameters and their corresponding types, distinguishing the different types of constructors is done by the compiler.

class Hospital {
int variable1, variable2;
double variable3;
public Hospital(int doctors, int nurses) {
variable1 = doctors;
variable2 = nurses;
}
public Hospital(int doctors) {
variable1 = doctors;
}
public Hospital(double salaries) {
variable3 = salaries

14. Define Copy constructor in java.
Copy Constructor is the constructor used when we want to initialize the value to the new object from the old object of the same class.

class InterviewBit{
String department;
String service;
InterviewBit(InterviewBit ib){
this.departments = ib.departments;
this.services = ib.services;
}
}
Here we are initializing the new object value from the old object value in the constructor. Although, this can also be achieved with the help of object cloning.

AEM Interview Questions

AEM Interview Questions

1. Explain AEM Architecture.

Platform JAVA
Because Adobe Experience Manager (AEM) is a Java web application, it requires a Java Runtime Environment on the server (JRE). JRE 1.6 is required, although JRE 1.7 is highly recommended.
Granite Worktop

Adobe's open web stack is called Granite. It is the technical foundation upon which AEM is constructed.

FRAMEWORK FOR OSGI

OSGi is a Java-based dynamic software component system. An application on an OSGi-based system is made up of a collection of components, referred to as bundles in OSGi, that may be dynamically installed, started, paused, and uninstalled during runtime without having to restart the entire application. Bundle administration is available in a running AEM instance via the AEM Web Console at http://:/system/console/bundles.

ENGINE FOR SERVLETS

The built-in CQSE servlet engine runs as a service in a quickstart installation.

a bundle that is part of the OSGi framework The handling of servlets in a war file installation is assigned to a third-party application server. When AEM is deployed via the standalone quickstart jar file, it comes with a built-in servlet engine (CQSE), which operates as a bundle within the OSGi framework.

REPOSITORY OF JCR CONTENT

The built-in CRX content repository, which is an implementation of the Java Content Repository Specification, stores all data in AEM (JCR).

AEM's built-in content repository stores all of the data.

CRX is the name of the AEM repository.

Adobe's implementation of the Content Repository Specification for Java Technology 2.0, also known as JSR-238, is an official standard released by the Java Community Process (version 1.0 was known as JSR-170)

DELIVERY OF SLING CONTENT

AEM is an acronym for

developed with Sling, a REST-based Web application framework that makes developing content-oriented apps simple. Sling's data is stored in a JCR repository, such as Apache Jackrabbit or, in the case of AEM, the CRX Content Repository. The Apache Software Foundation has accepted Sling as a contribution.

Modules for AEM

Adobe Experience Manager is built on the Granite platform and runs on top of the OSGi framework. WCM, DAM, Workflow, and other AEM modules are examples.

2. What is the difference between CQ5 and AEM?

AEM 6.1/6.0's significant tech stack updates.

1. Jackrabbit Oak: Oak outperforms JCR in terms of performance and scalability. To allow clustering and user-generated data situations, you can alternatively use a NoSQL database like MongoDB as the persistence layer.

2. Attractive: A new templating language that makes markup seem nice, enforces the separation of markup and logic, and by default protects against XSS.

3. Touch UI: CQ5's ExtJS-based Classic UI has been upgraded to Touch UI, which supports touch-enabled devices and is created with the Coral UI framework.

4. Search - Apache Solr: Lucene was the default search engine in CQ5, however, it has been replaced by Solr. The Solr server can now be used as the search engine for your AEM application.

3. What is new in AEM 6.2?

Adobe Experience Manager 6.2 is an upgrade to the code base of Adobe Experience Manager 6.1. It adds new and improved features, as well as critical customer fixes, high-priority customer enhancements, and general bug fixes geared toward product stability. It also includes all feature packs, hotfixes, and service packs for Adobe Experience Manager 6.1.

An overview is provided in the table below.

Features of Security

Support for password history has been added.

Authentication token expiration can be customized.

Continual effort: Sling login administrative API usage has been switched to Service Users in many places of the product.

The following are the main enhancements to the repository:

MongoDB Enterprise 3.2 is supported.

Enhancements to TarMK's cold standby to provide a procedural failover for high availability.

Faceted Search, Suggestions, Spellchecker, and other Oak search innovations

In terms of performance, scalability, and resilience, general.

Support for Revision Cleanup (Offline revision cleanup is the recommended way of performing revision cleanup)

The 2016 Adobe Marketing Cloud UI design is implemented in AEM 6.2. (also known as Shell 3). Furthermore, the user interface is transitioning from Coral UI 2 to the Coral 3 UI framework, which is based on Web Components.

"Explain Query" on the Operations Dashboard provides insight into the mechanics of your queries to aid diagnosis and optimization.

In the Tools/Operations section, specific repository features can be monitored using a configurable timeline view.

The Status.zip file in the Tools/Operations/Diagnosis section now contains a configurable series of Java thread dumps.

User Sync Diagnostics are used to ensure that users and groups are consistent across AEM instances.

Distribution of Content:

Replication of packages to support extra-large activation volumes

Configure priority-queuing to Allow for a divide between urgent and backlog activations.

The Status.zip file in the Tools/Operations/Diagnosis section now contains a configurable series of Java thread dumps.

Advanced notifications and auto-unlocking of stalled replication queues.

4. What is new in AEM 6.3?

Adobe Experience Manager 6.3 is a patch for Adobe Experience Manager 6.2. It adds new and improved features, as well as critical customer fixes, high-priority customer enhancements, and general bug fixes aimed at product stability. All feature packs, hotfixes, and service packs for Adobe Experience Manager 6.2 are included.

Cleaning Up Your Revisions on the Internet

Section of Oak TarMK is a new Tar file format that optimizes runtime and maintenance. It claims to be faster than TarMK and to fully allow online revision cleanups. Anyone who has worked with AEM to automate cloud processes will appreciate this last point. There will be no need to shut down an instance to perform repository compaction and cleanup.

As part of the maintenance chores, it is now scheduled to run regularly.

Maps of activities

The AEM Sites Activity Map interface, which was introduced in AEM 6.3, allows the Adobe Analytics Activity Map to display analytics data directly on the AEM Sites page, allowing AEM Authors to see how their pages are used down to the link level. more

Workflow in bulk

Faster workflow-related tasks and the capacity to handle numerous things with one click have increased productivity.

Export Sling Models

In Sling Models v1.3.0, the Sling Model Exporter was introduced. This new feature allows users to add new annotations to Sling Models that specify how the model should be exported as JSON.

Define a resource Type using the @Model annotation to tie the exporter framework to a Sling model.

and provide the Jackson exporter as well as the Sling extension using the @Exporter annotation (and optionally the selectors). It's also possible to utilize Jackson annotations to change the model's JSON representation.
Integration with Livefyre

Adobe purchased Livefyre in May 2016 and has now incorporated it as a set of components, as well as a user-generated content ingestion and moderation panel, into Adobe Experience Manager. Once a Livefyre cloud service configuration is set up, content creators can use components (found in /libs/social/integrations/livefyre/components) to surface user-generated content from social networking sites like Twitter and Instagram on a page. Traditional branded experiences combined with social media content will show to be an efficient strategy to increase client engagement. The usage of A separate Assets and Livefyre license is required for Livefyre, however, a Communities license is not required.
