QuarkusComponentTest in Gradle

[peterfortuin]

Describe the bug

When creating an @QuarkusComponentTest within a Quarkus project that you build with Gradle you get an IllegalStateException: Invalid test path.

java.lang.IllegalStateException: Invalid test path: /Users/peter/Development/heating-service/valve/build/classes/java/test/com/peterfortuin/heating/valveservice/pipelines/valveupdates/TemperatureRequestSenderTest.class

The problem is in QuarkusComponentTestExtension.java. The problem is with this part of the code:

int targetClassesIndex = testPath.indexOf(TARGET_TEST_CLASSES);
// NOTE: continuous testing is not supported at the moment
if (targetClassesIndex == -1) {
    throw new IllegalStateException("Invalid test path: " + testPath);
}

Together with

private static final String TARGET_TEST_CLASSES = "target/test-classes";

The code is looking if the path to the class with the testcode contains target/test-classes. This is true for Maven builds but not for Gradle builds.

Expected behavior

I expect to be able to use @QuarkusComponentTest to write component tests with Gradle als build tool and able to run them without the IllegalStateException: Invalid test path.

Actual behavior

At the moment every test class that is annotated with @QuarkusComponentTest in a project that you build with Gradle will fail with IllegalStateException: Invalid test path.

How to Reproduce?

Steps to reproduce:

1. Create a Quarkus project with Gradle as build tool.
2. Create a component test with @QuarkusComponentTest annotation.
3. Run the tests with ./gradlew test or run them from IntelliJ.

I see that a Kotlin label has been added, but I have no idea why. I think it's unrelated to Kotlin.

I see that a Kotlin label has been added, but I have no idea why. I think it's unrelated to Kotlin.

That is a false positive because there is a Kotlin word in the Gradle version output. I've removed the label
