android - 如何测试 Intent 是否已广播

Question

单击“记录”按钮时，我正在广播一个 Intent 。传递了一个 bool 变量，显示是否开始录制。生成 Intent 的代码是:

Intent recordIntent = new Intent(ACTION_RECORDING_STATUS_CHANGED);
recordIntent.putExtra(RECORDING_STARTED, getIsRecordingStarted());
sendBroadcast(recordIntent);

为了测试这段代码，我在测试中注册了一个接收器。收到了 Intent ，但传递的变量不一样。如果我调试代码，我可以看到该值与发送的值相同，但当我得到它时，它的值不同。

@Test
public void pressingRecordButtonOnceGenerateStartRecordingIntent()
        throws Exception {
    // Assign
    AppActivity activity = new AppActivity();
    activity.onCreate(null);
    activity.onResume();

    activity.registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent intent) {
            // Assert
            ShadowIntent shadowIntent = Robolectric.shadowOf(intent);
            assertThat(shadowIntent
                    .hasExtra(AppActivity.RECORDING_STARTED),
                    equalTo(true));
            Boolean expected = true;
            Boolean actual = shadowIntent.getExtras().getBoolean(
                    AppActivity.RECORDING_STARTED, false);
            assertThat(actual, equalTo(expected));

        }
    }, new IntentFilter(
            AppActivity.ACTION_RECORDING_STATUS_CHANGED));

    ImageButton recordButton = (ImageButton) activity
            .findViewById(R.id.recordBtn);

    // Act
    recordButton.performClick();
    ShadowHandler.idleMainLooper();

}

我也测试了实际 Intent 而不是它的影子，但结果相同

Answer 1

使用 get() 而不是 getBoolean() 对我有用。

public void pressingRecordButtonOnceGenerateStartRecordingIntent()
        throws Exception {
    // Assign
    BreathAnalyzerAppActivity activity = new AppActivity();
    activity.onCreate(null);
    activity.onResume();

    activity.registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent intent) {
            // Assert
            assertThat(intent
                    .hasExtra(AppActivity.RECORDING_STARTED),
                    equalTo(true));
            Boolean expected = true;
            Boolean actual = (Boolean)intent.getExtras().get(
                    AppActivity.RECORDING_STARTED);
            assertThat(actual, equalTo(expected));


        }
    }, new IntentFilter(
            AppActivity.ACTION_RECORDING_STATUS_CHANGED));

    ImageButton recordButton = (ImageButton) activity
            .findViewById(R.id.recordBtn);

    // Act
    recordButton.performClick();
    ShadowHandler.idleMainLooper();

}
