Maven ignores tests defined as ArchTest fields

[Scaronthesky]

I'm under the impression that Maven seems to ignore ArchUnit tests which are defined as fields with the @archtest annotation.

I copied some of the CodingRulesTest from the ArchUnit-Examples project, e. g. "No Access to Standard streams". These tests work fine when I execute them with IntelliJ. Maven completely ignores them, though. Maven executes only tests which are defined as "proper" test methods.

Is this a configuration issue or a bug? I had a look at the documentation and issues but could not find anything.

import static com.tngtech.archunit.library.GeneralCodingRules.NO_CLASSES_SHOULD_ACCESS_STANDARD_STREAMS;
import com.tngtech.archunit.core.domain.JavaClasses;
import com.tngtech.archunit.junit.AnalyzeClasses;
import com.tngtech.archunit.junit.ArchTest;
import com.tngtech.archunit.lang.ArchRule;

@AnalyzeClasses(packages = "de.package")
public class CodingRulesTest {

  // Will silently be ignored by Maven
  @ArchTest
  public final ArchRule no_access_to_standard_streams = NO_CLASSES_SHOULD_ACCESS_STANDARD_STREAMS;

  // Will be executed
  @ArchTest
  public void assertNoAccessToStandardStreams(JavaClasses classes) {
    NO_CLASSES_SHOULD_ACCESS_STANDARD_STREAMS.check(classes);
  }
}

In the examples project the ArchRule fields are private. I made the public but it makes no difference. They are still ignored.

Thanks for raising the issue! I couldn't exactly reproduce your problem, but saw that ArchUnit 1.1.0 is not fully compatible with JUnit 5.10, so I assume that your issue is related to that.

mvn test

fails with

java.lang.NoSuchMethodError: 'java.util.Set org.junit.platform.engine.TestDescriptor.getAncestors()'

– which can be resolved by downgrading junit-jupiter-api to 5.9.3 or upgrading archunit-junit5 to a version built against junit-platform-engine:1.10.0.

The issue of my example above can also be solved by explicitly adding the new junit-platform-engine:

    <dependency>
      <groupId>org.junit.platform</groupId>
      <artifactId>junit-platform-engine</artifactId>
      <version>1.10.0</version>
      <scope>test</scope>
    </dependency>

@Scaronthesky, does this help in your case, too?

[Scaronthesky]

Hmm, I don't know what changed between last week and now, but I can't seem to reproduce this issue anymore. It works even without adding the aformentioned "org.junit.platform:junit-platform-engine" dependency. Maybe some one else is suffering from the same problem in the future.

For what it's worth I ran into the same issue as you while trying to create a minimum working example. After adding the "org.junit.platform:junit-platform-engine" dependency the tests can be run and both tests (field and method) are executed. Thanks for your support.
