Using JUnit Test Suites to Organize Tests

Estimated reading: 2 minutes 180 views

As test cases increase, organizing them into test suites becomes necessary. JUnit allows us to group multiple test classes into a test suite, making it easier to manage and execute tests systematically. In this guide, we will demonstrate how to create and execute JUnit test suites for web applications.

Updating `pom.xml` to Support JUnit Test Suites

Before creating the test suite, update your pom.xml file to include the necessary dependencies and configurations:

Uppated pom.xml for JUnit Test Suites

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Creating a JUnit Test Suite

JUnit allows us to use the @Suite annotation to group multiple test classes. Below is how we define a test suite that includes LockedScreenTest and SignUpScreenTest.

JUnit Organizing Classes

package com.mqa.junit.tests;

import org.junit.platform.suite.api.SelectClasses;
import org.junit.platform.suite.api.Suite;

@Suite
@SelectClasses({
    LockedScreenTest.class,
    SignUpScreenTest.class
})
public class TestSuite {
}

Explanation of the Test Suite

@Suite → Marks this class as a test suite.
@SelectClasses → Specifies which test classes to include in the suite.
LockedScreenTest.class → Adds the Locked Screen Test to the suite.
SignUpScreenTest.class → Adds the Sign Up Screen Test to the suite.

Running the Test Suite

To run the test suite, use the following Maven command:

Running Test Suites

mvn -Dtest=TestSuite test

This will execute both LockedScreenTest and SignUpScreenTest in one run.

Conclusion

JUnit test suites help organize and manage multiple test cases efficiently. They enable better test execution control and structured test organization, ensuring improved maintainability and scalability of web application tests. With test suites, you can group related tests and run them together as a batch, improving test efficiency.
