Do you have a repro project that you could share with us?

There should be no need to excluding any dependencies: we automatically remove them from the test APK if they are in the main APK.

Yes, sorry androidx.test component.

I have some JUNit test like:

import androidx.appcompat.app.AppCompatActivity
import androidx.fragment.app.Fragment
import androidx.fragment.app.FragmentFactory
import androidx.fragment.app.testing.FragmentScenario
import androidx.fragment.app.testing.launchFragmentInContainer
import androidx.test.core.app.ActivityScenario
import androidx.test.ext.junit.runners.AndroidJUnit4
import androidx.test.rule.GrantPermissionRule
import org.junit.Assert
import org.junit.Rule
import org.junit.Test
import org.junit.runner.RunWith

/**
 * @author mtrakal on 20.10.2020.
 */
@RunWith(AndroidJUnit4::class)
class PermissionHelperTest {
    /**
     * grant all permissions for current Instrumentation (all test cases!) and not possible to revoke it! :/
     */
    @get:Rule
    var grantPermissions: GrantPermissionRule = GrantPermissionRule.grant()

    var helper: PermissionHelper = PermissionHelper()
    var activityScenario: ActivityScenario<AppCompatActivity> = ActivityScenario.launch(AppCompatActivity::class.java)
    var fragmentScenario: FragmentScenario<Fragment> = launchFragmentInContainer(factory = FragmentFactory())

    @Test
    fun `default provider`() {
        Assert.assertTrue(helper.provider is PermissionProviderDexterImpl)
    }

    @Test
    fun `camera permission granted`() {
        activityScenario.onActivity {
            helper.requestCamera(
                it,
                permissionGranted = { Assert.assertTrue(true) },
                permissionDenied = { Assert.assertTrue(false) }
            )
        }
    }

// TODO: Not possible test this case
    @Test
    fun `camera permission denied`() {
        activityScenario.onActivity {
            helper.requestCamera(
                it,
                permissionGranted = { Assert.assertTrue(false) },
                permissionDenied = { Assert.assertTrue(true) }
            )
        }
    }
}

In this scenario, I need to test the opposite scenario too. Not just permissionGranted, but permissionDenied too. But it's not possible, because at the beginning I grant permissions through:

@get:Rule
    var grantPermissions: GrantPermissionRule = GrantPermissionRule.grant()

this allow permissions, but after I'm not able test permissionDenied.

Or is there some other way, than split code to 2 files and in one have GrantPermissionRule call and in second file don't have it? It's crazy workaround have more files just for permissions...

This bug has not been updated in the last year. Please reopen if we still need to look into this.
