Why TestNG is used in Selenium?

TestNG is preferred by developers for its ability to write powerful test cases with the help of annotations, grouping, and parametrizing. It covers all classifications of test automation like Unit testing, Functional testing, End-to-End, and integration testing. It's available in the form of jar files.

How many TestNG methods are there?

In TestNG, there are ten types of annotations: @BeforeSuite - The @BeforeSuite method in TestNG runs before the execution of all other test methods. @AfterSuite - The @AfterSuite method in TestNG runs after the execution of all other test methods.

What is TestNG framework?

What is thread in TestNG?

Introduction to Threads in TestNG Threads in parallel testing refer to different parts in which the test execution will be divided and run parallelly. So if there are two threads and two methods, they will take one method each and run them parallelly (if we are running the methods parallelly).

How do I run a failed Testcase in TestNG?

How to run only failed test cases

Step 1) Right click on the java project (Demo A and B). Select the refresh option or simply select the java project and press F5.
Step 2) Then you will able to see the test-output folder.
Step 3) Right-click on this file and click on run as and select the option called “testNG suite”.

What is TestNG and Maven?

@AfterTest: A method with this annotation will be executed when all @Test annotated methods complete the execution of those classes inside the <test> tag in the TestNG. xml file. @BeforeSuite: It will run only once, before all tests in the suite are executed.

What is parallel in TestNG?

Parallel Testing using TestNG and Selenium Methods: Helps run methods in separate threads. Tests: Help to run all methods belonging to the same tag in the same thread. Classes: Helps to run all methods belonging to a class in a single thread. Instances: Helps run all methods in the same instance in the same thread.

What is the order of TestNG?

Why is Maven used in Selenium?

Why Use Maven to Manage Selenium Dependency? Maven can easily handle the entire lifecycle of a project which can include code generation, compilation, testing, validation, packaging, and much more. It works in phases rather than tasks and makes the build management process much easier.

Is TestNG a software?

TestNG is a testing framework for the Java programming language created by Cédric Beust and inspired by JUnit and NUnit. The design goal of TestNG is to cover a wider range of test categories: unit, functional, end-to-end, integration, etc., with more powerful and easy-to-use functionalities.

Does TestNG run tests in parallel?

TestNG allows the tests to run in parallel or concurrent mode. This means that based on the test suite configuration, different threads are started simultaneously and the test methods are executed in them.

What is parameterization in TestNG?

Parameterization in TestNG means we want to pass a parameter into the test with multiple values. Each value will run on the same test, and the output will be generated for the final analysis.

What is the maximum thread count in TestNG?

There is no TestNG thread count limit, I'm not quite sure where this limit exists but I would start by looking at the Javadoc of Executors. I'm trying to run TestNG tests in parallel, right now I've set “parallel=tests” & 'thread-count=25' but I see that only 10 threads are running at a time.

What is dependency in TestNG?

Test Dependency is a feature in TestNG that allows a test method to depend on a single or a group of test methods. This will help in executing a set of dependent tests to be executed before a test method.

What is IAnnotationTransformer in TestNG?

This interface IAnnotationTransformer modifies the default TestNG tests behavior at run time. Using this listener, we can modify values of all attributes defined in @Test annotation by calling their setters.
