Can not set a seed with the default ForgeConfigurator

[vincent314]

Hi,

I was just testing your lovely library after watching this video on youtube, and just got an error : I can not replay a test with a seed and the default ForgeConfigurator. It also happen with just @ForgeConfiguration (no seed and no Configurator provided)

class fr.xgouchet.elmyr.junit5.ForgeExtension cannot access a member of class fr.xgouchet.elmyr.ForgeConfigurator$NoOp with modifiers "private"
java.lang.IllegalAccessException: class fr.xgouchet.elmyr.junit5.ForgeExtension cannot access a member of class fr.xgouchet.elmyr.ForgeConfigurator$NoOp with modifiers "private"

Here is my very basic test class:

import fr.xgouchet.elmyr.annotation.IntForgery
import fr.xgouchet.elmyr.junit5.ForgeConfiguration
import fr.xgouchet.elmyr.junit5.ForgeExtension
import io.kotest.matchers.shouldBe
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.extension.ExtendWith

@ExtendWith(ForgeExtension::class)
@ForgeConfiguration(seed = 0x2af7b7def4L)
class FooTest {
    @Test
    fun testSomething(@IntForgery i: Int) {
        i % 2 shouldBe 0
    }
}

version: 1.2.0
kotlin: 1.4.20
junit: 5.6.0

Hi @vincent314, this seems like a weird issue, let me jump on it I'll try and fix it quickly.

After some investigation, this seem to only happen when kotest is used. I've not tested Elmyr with Kotest since it already has a property based testing support.

This was just fixed in version 1.3.1
