How to set up different types of tests using Gradle and JVM Test Suite Plugin

Check test-sets branch to see shorter implementation.

The project contains 3 types of tests:

• Unit tests
• Integration tests
• End-to-end tests

First of all, you need to add plugin to build.gradle file:

plugins {
    id 'jvm-test-suite'
}

Create a new folder in src to add your tests there.

.
├── ...
├── src
│   └── integrationTest
│       └── com.habchak
│           └── YourFunctionalTest.java
└── ...

To add another type of test you need to specify it in testing.suites section of build.gradle file.

For instance, if you want to add a new type of test called functional you need to add the following line:

testing {
    suites {
        test {
            useJUnitJupiter()
        }
        functionalTest(JvmTestSuite) {
            dependencies {
                implementation project()
            }
            targets {
                configureEach {
                    testTask.configure {
                        shouldRunAfter(test)
                    }
                }
            }
        }
    }
}

It's a good idea to make the check task depend on all types of tests because build runs check.

tasks.named('check') {
    dependsOn testing.suites.functionalTest
}

You can specify dependencies for each type of tests.

dependencies {
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.springframework.boot', module: 'spring-boot-test' //exclude from unit tests
    }
    integrationTestImplementation 'org.springframework.boot:spring-boot-starter-test'
    endToEndTestImplementation 'org.springframework.boot:spring-boot-starter-test'
    functionalTestImplementation 'org.springframework.boot:spring-boot-starter-test'
}
