Test suites with @Suite in JUnit - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of using @Suite in JUnit?

The @Suite annotation groups multiple test classes to run them together as one test suite, making it easier to organize and execute related tests.

beginner

How do you specify which test classes belong to a test suite using @Suite?

You use the @Suite.SuiteClasses annotation with an array of test class names inside the test suite class.

beginner

Write a simple example of a JUnit test suite using @Suite.

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
@Suite.SuiteClasses({TestClass1.class, TestClass2.class})
public class MyTestSuite {
}
 This runs TestClass1 and TestClass2 together.

beginner

What annotation must be used on a class to make it a test suite in JUnit?

The class must be annotated with @RunWith(Suite.class) to tell JUnit to run it as a suite.

beginner

Can a test suite class contain test methods?

No, a test suite class only groups other test classes and does not contain test methods itself.

Which annotation is used to specify the classes included in a JUnit test suite?

A @Suite.SuiteClasses

B @TestClasses

C @RunWithClasses

D @IncludeTests

The @Suite.SuiteClasses annotation lists the test classes to include in the suite.

What annotation must be placed on a class to run it as a JUnit test suite?

A @TestSuite

B @SuiteRunner

C @RunWith(Suite.class)

D @RunSuite

The @RunWith(Suite.class) annotation tells JUnit to run the class as a test suite.

Can a JUnit test suite class contain test methods?

A Yes, it can contain test methods.

B Only if it extends a test class.

C Only if annotated with @Test.

D No, it only groups test classes.

A test suite class only groups other test classes and does not contain test methods.

What is the main benefit of using a test suite with @Suite in JUnit?

A To run multiple test classes together easily.

B To write fewer test methods.

C To automatically generate test reports.

D To skip tests during execution.

Test suites help run multiple test classes together in one go.

Which import is necessary to use @Suite in JUnit 4?

A import org.junit.suite.Suite;

B import org.junit.runners.Suite;

C import org.junit.runner.Suite;

D import org.junit.suites.Suite;

The correct import for @Suite is org.junit.runners.Suite.
