In 2.1.4 , but I've also caught it in previous version.
Sometimes tests are not executed, but the following exception is thrown:
No ParameterResolver registered for parameter [io.luna.service.main.test.TestObjectBuilder builder] in constructor [public io.luna.service.main.test.finance.algorithm.reassignment.ReassignmentTest(io.luna.service.main.test.TestObjectBuilder,io.luna.service.main.finance.common.service.CompanyService,io.luna.service.main.finance.bank.service.PooledBankAccountService,io.luna.service.main.finance.user.service.UserAccountService,io.luna.service.main.finance.common.service.AssignmentService,io.luna.service.main.rbac.service.UserBankService,io.luna.service.main.finance.algorithm.repository.ReassignmentRepository,io.luna.service.main.finance.algorithm.service.ReassignmentService)].

Interesting thing is that it somehow depends on test class structure (hash?), so I suppose there's a race condition somewhere during tests instantiation or not enforced a proper order in some hash maps/sets.
I've caught it with my test class. I can reproduce the problem each time, unless I change the method name. Please look at the attached video.

          Same issue here with Micronaut 2.2.1 (default generated app from mn CLI) and Kotlin 1.4.10-1.4.20.
Sometime changes to code (especially annotations) lead to bean injection failures and other oddities. Happens with unit tests and application restarts.
gradle clean always fixes the issue.
IDE setup is not the cause since problem manifests from gradle test too.
Possibly caused by Kotlin annotation processor bug.
          @jameskleeh I cannot share the project, unfortunately.
@Happy-Neko Thanks for the hint with gradle clean, I'm going to try it.
BTW. I have gradle 6.7 and the problem is present in this version.

Do you have incremental compilation enabled in your build.gradle with anything like this?
micronaut {
    runtime("netty")
    processing {
        incremental(true)
        annotations("com.example.*")
          I have incremental  annotations processing enabled, however I was waiting a long time for them to work with kotlin and previously had it disabled and at the time I had this problem with tests as well.
I doesn't seem to be related to incremental annotations for me. When I bump into this problem, it's enough for me to change any method name to get rid of this. It's very weird.
          However, it seems it's gradle problem, because ./gradlew --no-build-cache cleanTest helps for me.
[EDIT]: Actually, --rerun-tasks option helps, not cleaning the cache.
