Hello, basic question here, I usually use Kotest by initializing my mocks with MockkAnnotations.init(this) inside the beforeEach block and I use lateinit var on my mocks. Is this bad or is this the recommended way?

I find that using val is not always possible as sometimes you have some expectations to setup first.

class MyClassTest : StringSpec() {

	private lateinit var myClass: MyInterface

	@RelaxedMockK
	private lateinit var myMock1: MockableThing1

	@RelaxedMockK
	private lateinit var myMock2: MockableThing2

	init {
		beforeEach {
			MockKAnnotations.init(this)

			myClass = MyClass(
				myMock1,
				myMock2
			)
		}
    }
    ...

I think you can setup the expectations even with val.

class MyClassTest : StringSpec({
    val myMock1 = mockk<MockableThing1>
    val myTarget = MyClass(myMock1)

    "MyTest" {
        every { <http://myMock1.xyz|myMock1.xyz>() } returns "ABC"
        <http://myTarget.xyz|myTarget.xyz>()
    }
})

OR

class MyClassTest : StringSpec({
    val myMock1 = mockk<MockableThing1> {
        every { <http://myMock1.xyz|myMock1.xyz>() } returns "ABC"
    }
    val myTarget = MyClass(myMock1)

    "MyTest" {
        <http://myTarget.xyz|myTarget.xyz>()
    }
})

This is usually how I write my tests

[LeoColman]

And you can use mockk(relaxed = true) to replacec @RelaxedMockk

I'll try it out @LeoColman, thanks!

[LeoColman]

Should also play a bit with IsolationMode if you're using verify

[Alexandre Brown]

Yes I have a global config for IsolationMode.InstancePerTest thank you

Just tried your approach, way less boilerplate, I love it!

[Alexandre Brown]

I'll definitely switch to your approach, thanks again for sharing it @LeoColman
