android-如何等到烤面包完成？仅在烤面包被先前测试掩盖后才开始第二次测试

概述这是我的意式浓缩咖啡的测试：@RunWith(AndroidJUnit4::class)classAddTraderActivityNetworkTest{privatevalcontext=InstrumentationRegistry.getInstrumentation().getContext()privatelateinitvarmockServer:MockWebServer@Rule@JvmField

这是我的意式浓缩咖啡的测试：

@RunWith(AndroIDJUnit4::class)class AddTraderActivityNetworkTest {    private val context = InstrumentationRegistry.getInstrumentation().getContext()    private lateinit var mockServer: MockWebServer    @Rule    @JvmFIEld    var addTraderIntentTestRule: IntentsTestRule<AddTraderActivity> = IntentsTestRule(AddTraderActivity::class.java)    @Before    fun setup() {        mockServer = MockWebServer()        mockServer.start(8081)    }    @Test    fun buttonStart_click_clIEntError_showToast() {        mockServer.enqueue(MockResponse()                .setResponseCode(400))        onVIEw(withID(R.ID.baseTextinputEditText))                .perform(typeText(BASE_TEST))        onVIEw(withID(R.ID.quoteTextinputEditText))                .perform(typeText(QUOTE_TEST))        onVIEw(withID(R.ID.startbutton))                .perform(click())        onVIEw(withText(R.string.clIEnt_error)).inRoot(ToastMatcher())                .check(matches(isdisplayed()))    }    @Test    fun buttonStart_click_clIEntError_TraderNotFound_showToast() {        mockServer.enqueue(MockResponse()                .setResponseCode(404)                .setbody(fileUtil.getStringFromfile(context, "Trader_404_not_add.Json")))        onVIEw(withID(R.ID.baseTextinputEditText))                .perform(typeText(BASE_TEST))        onVIEw(withID(R.ID.quoteTextinputEditText))                .perform(typeText(QUOTE_TEST))        onVIEw(withID(R.ID.startbutton))                .perform(click())        onVIEw(withText(R.string.Trader_not_added)).inRoot(ToastMatcher())                .check(matches(isdisplayed()))    }

当统计所有这些测试时,其中之一肯定会失败并显示以下消息：

androIDx.test.espresso.NoMatchingVIEwException: No vIEws in hIErarchy found matching: with string from resource ID: <2131623975>[clIEnt_error] value: ClIEnt ErrorVIEw HIErarchy:+>linearLayout{ID=-1, visibility=VISIBLE, wIDth=566, height=149, has-focus=false, has-focusable=false, has-window-focus=false, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, layout-params=WM.LayoutParams{(0,192)(wrapxwrap) gr=#51 ty=2005 fl=#1000098 fmt=-3 wanim=0x1030004}, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=1}|+->AppCompatTextVIEw{ID=16908299, res-name=message, visibility=VISIBLE, wIDth=416, height=83, has-focus=false, has-focusable=false, has-window-focus=false, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, layout-params=androID.Widget.linearLayout$LayoutParams@b08322e, tag=null, root-is-layout-requested=false, has-input-connection=false, x=75.0, y=33.0, text=Trader not added, input-type=0, ime-target=false, has-links=false}|at dalvik.system.VMStack.getThreadStackTrace(Native Method)at java.lang.Thread.getStackTrace(Thread.java:580)at androIDx.test.espresso.base.DefaultFailureHandler.getUserFrIEndlyError(DefaultFailureHandler.java:96)at androIDx.test.espresso.base.DefaultFailureHandler.handle(DefaultFailureHandler.java:59)at androIDx.test.espresso.VIEwInteraction.waitForAndHandleInteractionResults(VIEwInteraction.java:316)at androIDx.test.espresso.VIEwInteraction.check(VIEwInteraction.java:300)at com.myproject.activity.AddTraderActivityNetworkTest.buttonStart_click_clIEntError_showToast(AddTraderActivityNetworkTest.kt:64)at java.lang.reflect.Method.invoke(Native Method)at org.junit.runners.model.FrameworkMethod.runReflectiveCall(FrameworkMethod.java:50)at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12)at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47)at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17)at androIDx.test.internal.runner.junit4.statement.RunBefores.evaluate(RunBefores.java:80)at androIDx.test.internal.runner.junit4.statement.RunAfters.evaluate(RunAfters.java:61)at androIDx.test.rule.ActivityTestRule$ActivityStatement.evaluate(ActivityTestRule.java:531)at org.junit.rules.RunRules.evaluate(RunRules.java:20)

发生这种情况是因为开始了新的测试,但是仍然没有隐藏上一测试的吐司.结果我得到了找不到消息的吐司的错误：

androIDx.test.espresso.NoMatchingVIEwException: No vIEws in hIErarchy found matching: with string from resource ID: <2131623975>[clIEnt_error] value: ClIEnt Error

问题是：
我如何才能等到烤面​​包被藏起来并且只有在开始第二次测试之后？

解决方法:

这是Java中的一个函数,用于显示x毫秒的Toast

private Toast myToast;private voID showToast(int ms) {    myToast = Toast.makeText(this, "Your message", Toast.LENGTH_LONG);    new Handler().postDelayed(new Runnable() {        @OverrIDe        public voID run() {            myToast.cancel(); // do this to be sure Toast is gone            // here you can start your new test or set a flag to say Toast is finish        }    }, ms);}
