Tests

The Test task allows you to run any supported test library — JUnit, JUnit Platform or TestNG.

You can filter or skip the specified tests.

dependencies {
    testImplementation("junit:junit:4.13")
}

tasks.test {
    // useTestNG {   preserveOrder = true}
    useJUnit()
    maxHeapSize = "1G"
    //...
    
    filter {
        //include specific method in any of the tests
        includeTestsMatching("*UiCheck")

        //include all tests from package
        includeTestsMatching("org.gradle.internal.*")

        //include all integration tests
        includeTestsMatching("*IntegTest")
    }
}

dependencies {
    testImplementation 'junit:junit:4.13'
}

test {
    // useTestNG { preserveOrder true }
    useJUnit()
    maxHeapSize = '1G'
    // ...
    
    filter {
        //include specific method in any of the tests
        includeTestsMatching "*UiCheck"

        //include all tests from package
        includeTestsMatching "org.gradle.internal.*"

        //include all integration tests
        includeTestsMatching "*IntegTest"
    }
}

There are some properties of Task to control how the test process is launched.

command line

You can run tests from command line.

// Executes all detected tests
gradle test

// Executes all detected tests with failFast option
gradle test --fail-fast

# Executes all tests in SomeTestClass
gradle test --tests SomeTestClass

# Executes a single specified test in SomeTestClass
gradle test --tests SomeTestClass.someSpecificMethod

gradle test --tests SomeTestClass.*someMethod*

JUnit 5

To enable JUnit5 tests use following configuration.

repositories {
    mavenCentral()
}

dependencies {
    // see actual version
    testImplementation("org.junit.jupiter:junit-jupiter-api:5.7.2")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:5.7.2")
}

tasks.test  {
    useJUnitPlatform()
}
