Native Image Testing (Gradle)

Contents

• JUnit dependencies
• Running native tests
• Custom test suites

JUnit Dependencies

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.8.1'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.8.1'
    testImplementation 'junit:junit:4.13.2'
}

test {
    useJUnitPlatform()
}

Running Native Tests

./gradlew nativeTest

The output binary is located at: build/native/nativeTestCompile/<imageName> For plugin-specific testing options, see the Native Build Tools Gradle testing support. For debugger-based workflows, see Debug Native Tests in Maven and Gradle Projects.

Custom Test Suites

Register additional test binaries for integration tests or other test source sets:

graalvmNative {
    registerTestBinary("integTest") {
        usingSourceSet(sourceSets.integTest)
        forTestTask(tasks.named('integTest'))
    }
}

This creates two tasks:

• nativeIntegTestCompile — builds the native test binary
• nativeIntegTest — runs it
