TestNG annotations (@Test, @BeforeMethod, @AfterMethod) in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the @Test annotation in TestNG?

The @Test annotation marks a method as a test case that TestNG will run. It tells TestNG this method contains test code to execute.

Explain the role of @BeforeMethod in TestNG.

@BeforeMethod runs before each @Test method. It is used to set up preconditions or initialize resources needed for the test.

beginner

What does the @AfterMethod annotation do in TestNG?

@AfterMethod runs after each @Test method. It is used to clean up or release resources after the test finishes.

In what order do @BeforeMethod, @Test, and @AfterMethod run?

For each test method, TestNG runs @BeforeMethod first, then the @Test method, and finally @AfterMethod.

Why is it useful to use @BeforeMethod and @AfterMethod instead of putting setup and cleanup code inside @Test methods?

Using @BeforeMethod and @AfterMethod avoids repeating setup and cleanup code in every test. It keeps tests clean and easier to maintain.

Which TestNG annotation is used to mark a method as a test case?

A @Test

B @BeforeMethod

C @AfterMethod

D @BeforeClass

@Test marks a method as a test case to be executed by TestNG.

When does a method annotated with @BeforeMethod run?

A After each @Test method

B Before all tests in the class

C Before each @Test method

D After all tests in the class

@BeforeMethod runs before each individual @Test method.

What is the main purpose of @AfterMethod?

A To skip tests

B To run tests

C To initialize test data

D To clean up after each test

@AfterMethod is used to clean up or release resources after each test.

If you have 3 @Test methods, how many times will @BeforeMethod run?

A 3

B 1

C 2

D Depends on the test

@BeforeMethod runs before each @Test method, so it runs 3 times for 3 tests.

Which annotation would you use to prepare test data before each test?

A @AfterMethod

B @BeforeMethod

C @Test

D @AfterClass

@BeforeMethod is used to set up or prepare data before each test.

Describe how @BeforeMethod, @Test, and @AfterMethod work together in a TestNG test class.

Think about what happens before, during, and after each test method.

Explain why using @BeforeMethod and @AfterMethod can improve test code quality compared to putting setup and cleanup inside @Test methods.

Consider how repeating code affects your tests.
