Integration Test Gradle Plugin

Single line in build.gradle.kts to enable integration tests in JVM projects

Zero configuration, single responsibility gradle plugin for integration tests.

• Adds integrationTest task that executes tests under src/integration/*.
• Adds testAll task that executes tests under src/test/* and src/integration/*.
• Handles flags parameters to skip tests skipTest, skipIntegrationTest, skipUnitTest.
• Makes integration classpath extend test classpath and main classpath (in this order).
• Makes sure IntelliJ idea treats src/integration/* as test sources.
• Exposes kotlin internal scope (from main and test module) to integration tests.
• Integrates with test coverage tools like Jacoco and Kover.
• Integrates with test frameworks like JUnit5, Spock and Kotest.
• Compatible with gradle configuration cache.

Using the plugin

Update build.gradle.kts

plugins {
  id("com.coditory.integration-test") version "2.1.0"
}

dependencies {
  integrationImplementation(...)
}

Add integration tests under src/integration. That's it!

There are more details below but the rest is quite obvious as it suppose to be.

Sample usages with different test frameworks

See a project with all the examples.

Java + JUnit5 (project)

// build.gradle.kts
plugins {
    id("java")
    id("com.coditory.integration-test") version "2.1.0"
}

dependencies {
    testImplementation("org.junit.jupiter:junit-jupiter-api:5.11.0")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:5.11.0")
}

tasks.withType<Test> {
    useJUnitPlatform()
}

Groovy + Spock (project)

// build.gradle
plugins {
    id "groovy"
    id "com.coditory.integration-test" version "2.1.0"
}

dependencies {
    testCompile "org.spockframework:spock-core:2.4-M4-groovy-4.0"
}

tasks.withType(Test) {
    useJUnitPlatform()
}

Kotlin + JUnit5 (project)

// build.gradle.kts
plugins {
    kotlin("jvm") version "2.0.21"
    id("com.coditory.integration-test") version "2.1.0"
}

dependencies {
    testImplementation("org.junit.jupiter:junit-jupiter-api:5.11.3")
    testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.11.3")
}

tasks.withType<Test> {
    useJUnitPlatform()
}

Kotlin + Kotest (project)

// build.gradle.kts
plugins {
    kotlin("jvm") version "2.0.21"
    id("com.coditory.integration-test") version "2.1.0"
}

dependencies {
    testImplementation("org.junit.jupiter:junit-jupiter-api:5.11.3")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:5.11.3")
    testImplementation("io.kotest:kotest-runner-junit5:5.9.1")
}

tasks.withType<Test> {
    useJUnitPlatform()
}

Usage

Running tests:

# Runs tests from /src/test
./gradlew test

# Runs tests /src/integration
./gradlew integrationTest
./gradlew iT

# Runs all tests (/src/test and /src/integration)
./gradlew testAll
./gradlew tA

Skipping tests:

# Skip all tests
./gradlew clean build -x test integrationTest
# ...or skipTests=true/false
./gradlew clean build -PskipTest

# Skip tests from /src/test
./gradlew clean build -x test
# ...or skipUnitTests=true/false
./gradlew clean build -PskipUnitTest

# Skip tests from /src/integration
./gradlew clean build -x integrationTest
# ...or skipIntegrationTests=true/false
./gradlew clean build -PskipIntegrationTest

Test filtering is supported as well:

./gradlew iT --tests com.coditory.SampleTest.shouldWork

The no-plugin alternative

If you're against adding plugins to your build file, simply copy-paste the configuration from:

• Java + Junit5 (no plugin)
• Kotlin + Junit5 (no plugin)

...though mind the boilerplate

Migrating from 1.x.x to 2.x.x

• Skipping flags changed names. Use skipTests, skipUnitTests, skipIntegrationTests instead of skipTest, skipUnitTest, skipIntegrationTest.
• Added integration with Jacoco - coverage from integration tests is automatically included in report.
• Integration with JUnit4 is dropped.
