RobolectricTestRunner and suspend functions. Test function not found

@RunWith(RobolectricTestRunner::class)
class ServerUnitTest {
    @Test
    fun localAccessTest() {
        runTest {
            val res = LocalAccess.pingServer()
            assertEquals(res, 0)
            }
    }
}

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:testArtlocalDebugUnitTest'.

No tests found for given includes: [server.ServerUnitTest.localAccessTest](--tests filter)

If I remove '@RunWith(RobolectricTestRunner::class)', the test runs but there is no App Context -> so crash. LocalAccess requires App Context.
