Groovy & Gradle: JVM Automation and Build Engineering · Lesson

Unit & Integration Testing

Configure Gradle to run JUnit, TestNG, or Spock tests, and manage test dependencies.

Why Test? Gradle's Role

Automated testing is crucial for software quality. It helps find bugs early and ensures your code works as expected after changes.

Gradle provides excellent built-in support for running various types of tests, making it easy to integrate testing into your build process.

Unit Tests: Verify small, isolated parts of your code.
Integration Tests: Check how different parts of your system work together.

Gradle's Default Test Setup

When you apply the java plugin in Gradle, it automatically configures a test task for you. This task is responsible for finding and running your unit tests.

By default, Gradle looks for test classes in src/test/java (or src/test/groovy) and expects them to follow standard naming conventions (e.g., ending with Test).

// build.gradle
plugins {
    id 'java'
}

repositories {
    mavenCentral()
}
// The 'java' plugin automatically creates a 'test' task.
// No explicit 'test' task definition needed here.
