MockK - reinitialize mocks for each test

Question

I have some mocks created using: val someService = mockk<SomeService>(relaxed = true)

There are multiple tests in the file and I want the mock to be reset for each test

Is there currently a way to do this in MockK?

I know there is MockKAnnotations.init(this), but it didn't look like there was a way to set relaxed = true in the @Mock annotation

How about configuring your test framework to instantiate test object on every test method run? In JUnit 5 it's a default setup. In Kotest [set `isolationMode` to `IsolationMode.InstancePerTest`](https://kotest.io/docs/framework/isolation-mode.html#instancepertest) — Ilya Serbis, May 11 '23 at 14:03

For resetting specific mocks in MockK, you can use clearMocks() method. Pass the mocks you would like to reset to it.

To create relaxed mock via annotation just check @RelaxedMockK.

clearAllMocks() clears all mocks without the need of specifying them.
