We're experiencing the same problem when mocking Clock |
|
In our case it seemed to be an issue in combination with logback (version 1.4.5). When a As a workaround, we simply reduced the log level for the <?xml version="1.0" encoding="UTF-8"?>
<configuration>
<!-- Disable mockk logging to prevent stdObjectAnswer MockKException when mocking time -->
<logger name="io.mockk.impl.instantiation.AbstractMockFactory" level="error"/>
<logger name="io.mockk.impl.recording.states.AnsweringState" level="error"/>
</configuration> |

@e-wag thanks, but it's not working for me. |
|
I got this error from a HasMap, I fixed by manually returning a map val theMapToFix = mapOf<…>()
val mockObj = mockk<…> {
every { getterOfTheMap } returns theMapToFix
} |
|
Unfortunately I am observing the same issue and the workaround from @e-wag unfortunately does not fix it |
|
I reproduced this with normal mocking, not mockstatic. And what I realized is that we are not supposed to use the mocked objects as if they were real objects. |

This isn't Spring related. I got the same bug today when I tried to use mockkStatic for Instant::class in a non-spring environment. (specifics are work related) I'm going to see if I can figure out what's going on and open a PR to fix it |

@SamuelRuwe any update on this? Currently, in spring boot apps we have to fall back to an old version because of some incompatibility with Spring Boot, it would be great if we can move forward and keep the version aligned with SB reference |

Hey @artemptushkin, I got side tracked with other things. I'll try to get some time this weekend to look into it. If you're using Spring one thing you could do is use indirection by creating a bean that provides Instant to your services that you can also mock out for testing. It's been a bit since I've done Spring, but something like the below example may fit your use case @Bean
public InstantProvider instantProviderCreator() {
return new InstantProviderImpl();
}
interface InstantProvider {
Instant now();
}
class InstanceProviderImpl implements InstantProvider {
@Override
public Instant now() {
return Instant.now();
}
}
// in the tests
class MockInstanceProvider implements InstantProvider {
@Override
public Instant now() {
return Instant.EPOCH; (or any other arbitrary date you want for testing)
}
} |

@SamuelRuwe as a workaround it's okay but I here care mostly about being up-to-date with the latest versions w/o a need to write a code. We want to be on the latest just to be aligned |
