Dependency between tests in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does 'dependency between tests' mean in software testing?

It means one test relies on another test to run first or to pass before it can run correctly.

beginner

Why should we avoid dependencies between tests?

Because if one test fails, dependent tests may also fail, making it hard to find the real problem.

How can you declare a test dependency in TestNG with Selenium Java?

Use the @Test annotation with 'dependsOnMethods' attribute, for example: @Test(dependsOnMethods = {"testLogin"})

intermediate

What happens if a test that others depend on fails in TestNG?

The dependent tests are skipped automatically to avoid false failures.

beginner

Give one real-life example of test dependency.

Testing 'Add to Cart' depends on 'Login' test passing first, because you must be logged in to add items.

In TestNG, how do you specify that a test depends on another test?

A @Test(dependsOnMethods = {"methodName"})

B @DependsOnTest("methodName")

C @Test(priority = 1)

D @Test(enabled = false)

The correct way is to use @Test with dependsOnMethods attribute listing the method names.

What is a risk of having dependencies between tests?

A Tests run faster

B Tests become independent

C Tests always pass

D Failure in one test can cause others to skip or fail

If one test fails, dependent tests may skip or fail, hiding the real issue.

If test A depends on test B, and test B fails, what happens to test A in TestNG?

A Test A runs anyway

B Test A passes automatically

C Test A is skipped

D Test A runs before test B

TestNG skips dependent tests if the tests they depend on fail.

Which of the following is a good practice regarding test dependencies?

A Avoid dependencies to keep tests independent

B Make all tests dependent on each other

C Write tests that never fail

D Run tests in random order

Avoiding dependencies helps tests run independently and makes debugging easier.

What attribute in TestNG @Test annotation controls test dependencies?

A priority

B dependsOnMethods

C enabled

D groups

dependsOnMethods specifies which tests must run and pass before the current test.

Explain what test dependency is and why it can be problematic.

Think about how one test relying on another can affect test results.

Describe how to declare a test dependency in Selenium Java using TestNG and what happens if the dependent test fails.

Recall the TestNG annotation and test execution flow.
