Error in the AOT test process if there are two tests that check an actuator endpoint.

[ruben-garciapariente]

Hello

I'am using SB 3.0.2. I'm trying to pass the tests with native compilation with mvn -PnativeTest clean install and I get the following error

2023-02-22T09:14:51.320+01:00  WARN 28134 --- [           main] o.s.t.c.aot.TestContextAotGenerator      : Failed to generate AOT artifacts for test classes [com.example.testactuatornative.Test2ITTest]

I think this happens if I have two tests of type @SpringBootTest with property management.server.port=0.

I have tried to create a minimal example: https://github.com/ruben-garciapariente/test-actuator-native

Thanks & regards

Thanks for the report, there's something wrong here. It seems that if two management contexts exists, it leads to this error.

If i for example remove the value1=value1 and value2=value2 properties from your tests, the context will be cached and the error is gone.

I stumbled across the same error. Here is my repo with the error: https://github.com/Jul13nT/native-test-actuator

Run ./gradlew test and I get the exact same error.

One difference is that the management.server.port is set globally in application.properties. Then I have one test with @SpringBootTest and one with @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT).

Because of this, none of our tests of all our services are running and it prevents us of using GraalVM. Is there a possible workaround?

I also ran into this bug in the same way.

To work around it, I moved all management.* properties into a properties file named application-actuator.properties, and then I'm compiling and running the application with the actuator profile enabled, but during testing I don't activate this profile.

If you do want to create integration tests to verify the actuator, it's still possible by creating a test classes annotated with @ActiveProfiles("actuator"), but you have to be careful not to create multiple test classes with this profile that might also try to change the test context in a different way.

I believe this is a duplicate of spring-projects/spring-framework#28974.

Oh well, a duplicate of spring-projects/spring-framework#30861 then.
