Espresso 测试在尝试检查是否发送意图时未能记录意图

Question

我正在尝试使用 Espresso 对我创建的 AdjustableWebView class 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
}

我的结果是这样的：

IntentMatcher: (has action: is "android.intent.action.GET_CONTENT" or has action: is "android.intent.action.CHOOSER")

FAILURES!!!
Tests run: 1,  Failures: 1

我输入了日志语句，并且能够验证我的代码是否使用 startActivityForResult 启动了 activity 并向 activity 提供了 ACTION_CHOOSER 意图，但是由于某种原因，无论我做什么，我都无法记录意图，而且我的测试失败了。即使我删除 intending 行并让 activity 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），activity 正确打开，结果onActivityResult 中传递的代码是 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，告诉我如何解决这个问题吗？我不想检查打开的 activity，因为我想让我的实现尽可能通用（我想检查的是发送了一些意图，我知道会有一些 activity 来处理它，但我没有指定哪个 activity 正在做这项工作。

我查看了几篇 Whosebug 帖子，但没有任何帮助:(。

我的确切情况是我试图点击一个 HTML 输入标签，然后记录意图。我用的是浓缩咖啡。我的一位同事帮助我解决了这个问题，并且能够通过使用 UIAutomator 而不是 Espresso 来进行测试。
