Error in Test Case After Upgrading to 1.13.1 with Swagger

[KimJohn Quinn]

I just upgraded to 1.13.1 and my test cases, which are just stubs with nothing in them except a single test that prints hello world, started to fail.  What is odd is that it is only happening in my "services," other tests are running fine.

I get this error:

java.lang.RuntimeException:

The test cases failing look like this:

@Tag("unit")

@QuarkusTest

@Disabled

public class QueryResourceTest {

    @Test

    @Disabled

    public void should_run() {

        log.debug("I am running -------------------------------");

    }

    @Test

    @Disabled

    public void testHelloEndpoint() {

        given()

          .when().get("/hello")

          .then()

             .statusCode(200)

             .body(is("Hello RESTEasy Reactive"));

    }

}

@Tag("unit")

@QuarkusTest

Can you share a small reproducer?

Hello Phillip.

Attached is a reproducer as close as possible - for the most part I just killed all the code but the test.  I think it might be helpful to include the Maven POM configurations in their entirety too in case it is something I am doing there.

These are some things I have been doing and/or tested:

• I was refactoring the "application.yml" files with the intent of having those values merged into the final service (in this case "client").
  
  
• Downgraded back to 1.13.0 - this works fine.  The below shows the output of the test running fine.
  
  
• Upgraded back to 1.13.1 - this fails with the error above. @Disable'ing the test gets past the error of course.
  
  
• Double-checked I was running the actual codebase the same as the reproducer (in one I used JUnit5 tags).  
  
  
• Reran the reproducer using the same steps above (downgrading it to 1.13.0 works).
  
  
• In both cases, ignoring the test, it appears I can run the service and even Swagger without issue.

From the looks of it, it looks like Swagger is looking for the base path or something and that is not there for whatever reason. I can trace/dig into it more if needed...

Let me know if I should provide anything else.

Thanks.

I can confirm that this is a bug, I am not too sure what changes between 1.13.0 and 1.13.1 that cause this, I am still investigating. I'll do a fix that should be in 2.0 and if there is a 1.13.2 / 1.14.0 we can backport

[Phillip Krüger]

I created https://github.com/quarkusio/quarkus/pull/16383 for this.
