How to debug, why Spring Boot integration test context is not reused between tests?

Question

I got another tricky question for the crowd. I got two separate test files reusing the same Context class. I would expect them to reuse the same context, alas Spring ist started two times, prolonging the build time. Do you have any ideas how to figure out / debug, what triggers the context reload?

The test classes look like:

@SpringBootTest(
  classes = [HttpProxyTestContext::class]
)
@AutoConfigureWireMock(port = 8082)
internal class AuthOpenidConnectSpringIT {
...
}

and

@SpringBootTest(
  classes = [HttpProxyTestContext::class]
)
@AutoConfigureWireMock(port = 8082)
internal class AuthOidcWebClientIT {
...
}

The Context class is

@JooqTest
@ComponentScan(basePackages = ["de.denktmit.someproject.springconfig"])
class HttpProxyTestContext {}

Answer 1

I was finally able to figure out, that the problem somehow arose from using @AutoConfigureWireMock(port = 8082). I found it out by experimenting with the annotations used. Finally I slightly adjusted my test setup and finally my context is reused. Here's how I did it, thats my test only config:

@SpringBootConfiguration
@ComponentScan(basePackages = ["de.denktmit.someproject.springconfig"])
@AutoConfigureJooq
class HttpProxyTestContext {

  @Bean(destroyMethod = "stop")
  fun wiremock(): WireMockServer {
    val wireMockServer = WireMockServer(wireMockConfig().port(8082))
    wireMockServer.start()
    WireMock.configureFor("localhost", 8082);
    return wireMockServer
  }

}

And I just gets picked up as easy as

@SpringBootTest
internal class AuthOpenidConnectSpringIT {
  ...
}

@SpringBootTest
internal class AuthOidcWebClientIT {
   ...
}

Wiremock @BeforeEach setup left untouched and is the same as before. May it be helpful.

Good night and best regards,
