Hello, I’m using mocKMP, want to say ty for nice plugin.
I have a question, is it possible to override mock return value in the concrete unit test?

[romainbsl]

You mean something like this?

mocker.every { db.loadUser("123") } returns null // first call
mocker.every { db.loadUser("456") } returns FakeUser() // second call

[romainbsl]

Or like this?

mocker.every { db.loadUser("123") } returns null // first call
// Do something that triggers the first call
mocker.every { db.loadUser("123") } returns FakeUser() // second call

[Dmitry Danilau]

something like

@BeforeTest
fun setup() { // should use library setup func.
   mocker.every { db.loadUser("123") } returns null // to bypass all test that in flow using that mock
}


@Test
fun test() {
 mocker.every { db.loadUser("123") } returns FakeUser() // specifically check how flow behaves with the return value

 // test logic
}

[romainbsl]

You can do this using a variable

// Declare reusable mock
val everyUserLoad by lazy { mocker.every { db.loadUser("123") } }

@BeforeTest
fun setup() { // should use library setup func.
everyUserLoad returns null // to bypass all test that in flow using that mock
}


@Test
fun test() {
everyUserLoad returns FakeUser() // specifically check how flow behaves with the return value
// test logic
}

Thank you, will try that approach
