Question

Здесь тесты моего эспрессо;

@RunWith(AndroidJUnit4::class)
class TradersActivityNetworkTest {
    private val context = InstrumentationRegistry.getInstrumentation().getContext()
    private lateinit var mockServer: MockWebServer


    @Rule
    @JvmField
    var tradersIntentTestRule = IntentsTestRule(TradersActivity::class.java, false, false)
    //var tradersIntentTestRule = ActivityTestRule(TradersActivity::class.java)

    @Before
    fun setup() {
        mockServer = MockWebServer()
        mockServer.start(8081)
    }

    @Test
    fun network_clientError_showToast() {
        tradersIntentTestRule.finishActivity()
        //stub response
        mockServer.enqueue(MockResponse()
                .setResponseCode(400))
        // start activity
        tradersIntentTestRule.launchActivity(Intent())

        onView(withText(R.string.client_error)).inRoot(ToastMatcher())
                .check(matches(isDisplayed()))
    }

    @Test
    fun network_serverError_showToast() {
        tradersIntentTestRule.finishActivity()
        mockServer.enqueue(MockResponse()
                .setResponseCode(500))
        // start activity
        tradersIntentTestRule.launchActivity(Intent())

        onView(withText(R.string.server_error)).inRoot(ToastMatcher())
                .check(matches(isDisplayed()))
    }

    @After
    @Throws
    fun tearDown() {
        // We're done with tests, shut it down
        mockServer.shutdown()
    }

}

Здесь пользовательский подборщик

class ToastMatcher : TypeSafeMatcher<Root>() {

    override fun describeTo(description: Description) {
        description.appendText("is toast")
    }

    override fun matchesSafely(root: Root): Boolean {
        val type = root.getWindowLayoutParams().get().type
        if (type == WindowManager.LayoutParams.TYPE_TOAST) {
            val windowToken = root.getDecorView().getWindowToken()
            val appToken = root.getDecorView().getApplicationWindowToken()
            if (windowToken === appToken) {
                return true
            }
        }
        return false
    }
}

Запуск только одного теста "network_clientError_showToast"

gradlew app:connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=com.myproject.activity.TradersActivityNetworkTest#network_clientError_showToast

Успешное прохождение.Хорошо.

Запустите еще один тест (только этот тест) "network_serverError_showToast()" с помощью

gradlew app:connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.class==com.myproject.activity.TradersActivityNetworkTest#network_serverError_showToast

Успешный проход.Хорошо.

Теперь я хочу запустить все тесты по;

gradlew app:connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=com.myproject.activity.TradersActivityNetworkTest

тезис "network_serverError_showToast" не пройден с сообщением об ошибке:
