When using Data Driven Testing, separate rows are not treated as separate tests

Hi, I found out that this is probably not working as expected. When using Data Driven Testing, methods like before/afterTest are not called for every row of each test.

import io.kotlintest.Description
import io.kotlintest.data.forall
import io.kotlintest.shouldBe
import io.kotlintest.specs.StringSpec
import io.kotlintest.tables.row

class TestSpec : StringSpec() {

    var myMock = 10

    init {
        "myMock should be equal 10" {
            forall(
                row("first test"), row("second test")
            ) { sum ->
                //expect
                myMock shouldBe 10

                //side effect
                myMock = 11
            }
        }
    }

    override fun beforeTest(description: Description) {
        //like resetting mocks between tests
        myMock = 10
    }
}

The same story is with overriding method isInstancePerTest. I would expect that new instance of class will be created for every row for every test.

The main usecase for this is resetting mocks after every test.

I hope that this is a bug, Maciej

Thanks for replies. I understand the cause of the problem, but from user perspective every row should be treated as separate test. Some frameworks (e.g. Spock @Unroll) even create separate test entries for each data row.

It would be great if this would work like this in Kotlin Test. Otherwise using mocks is really error-prone.

Yes it works. Thank you.
