JUnit test-engine implementation that wraps the standard JUnit vintage-engine and adds support for timeouts per test-class.

Apply this engine instead of the junit-vintage-engine.

Examples

Gradle (Kotlin)

dependencies {
    testImplementation("org.junit.platform:junit-platform-launcher:1.6.2")
    testImplementation("org.junit.jupiter:junit-jupiter-api:5.6.2")

    testRuntimeOnly("org.caffinitas.junitvintagetimeout:junitvintagetimeout:0.1.1")
}

tasks.withType<Test>().configureEach {
    systemProperty("junit.jupiter.extensions.autodetection.enabled", "true")
    useJUnitPlatform() {
        includeEngines("timeout-junit-vintage")
    }
}

Maven

TODO (PR welcome)

Configurables

• The config parameter junit.vintage.execution.timeout.seconds (also configurable as a system property) defines the timeout in seconds. A timeout of <=0 means no timeout.

Note

The (current) implementation invokes the vintage-engine via a separate thread (named vintage-timeout-*). If the test runs too long (timeout), that thread is interrupted. This is a "best effort" approach that does not (and cannot) guarantee that all resources occupied by a test will be freed upon a timeout. So the probably best approach to run tests with a timeout setting is to never reuse a test-worker-JVM - in other words: spawn a new JVM for each test class.
