Espresso测试在试图检查是否发送了意图时未能记录意图

Question

我正在尝试使用Espresso对我创建的AdjustableWebView类进行集成测试。

我的测试是这样的：

@Test
public void myTest() {
// intents.init() is done in the @Before setup() method

// ... some code to set up permissions correctly

// ensure that the activity doesn't actually open
Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
Intent contentIntent = new Intent(Intent.ACTION_GET_CONTENT);
Instrumentation.ActivityResult contentResult = new Instrumentation.ActivityResult(Activity.RESULT_CANCELED, contentIntent);
Instrumentation.ActivityResult chooserResult = new Instrumentation.ActivityResult(Activity.RESULT_CANCELED, chooserIntent);
intending(hasAction(Intent.ACTION_GET_CONTENT)).respondWith(contentResult);
intending(hasAction(Intent.ACTION_CHOOSER)).respondWith(chooserResult);
// ... some code to load page in webview
// ... some code to click on the proper element in the webview
// verify
intended(anyOf(hasAction(Intent.ACTION_GET_CONTENT), hasAction(Intent.ACTION_CHOOSER)));
// intents.release() is done in the @After teardown() method
}

我的结果是：

IntentMatcher: (has action: is "android.intent.action.GET_CONTENT" or has action: is "android.intent.action.CHOOSER")
Matched intents:[]

我输入了日志语句，能够验证我的代码是否使用startActivityForResult启动了一个活动，并为该活动提供了ACTION_CHOOSER意图，但由于某种原因，无论我做什么，我都无法记录意图，因此我的测试失败了。即使我删除了intending行并让活动正常打开，并且我可以验证是否创建了正确的意图(使用Log语句(，活动也会正确打开，并且传递给onActivityResult的结果代码是RESULT_CANCELLED(再次使用Log语句验证(，但我仍然无法记录意图。

有人能为我指明正确的方向吗？我不想检查打开的活动，因为我想让我的实现尽可能通用(我只想检查是否发出了一些意图，我知道会有一些活动来处理它，但我没有指定是哪个活动在做这项工作(。

我看了几个StackOverflow的帖子，但没有任何帮助：(.

我的确切情况是，我试图点击HTML输入标记，然后记录意图。我用的是浓缩咖啡。我的一位同事帮助我完成了这项工作，并通过使用UIAutomator而不是Espresso使测试工作正常。
