Question

我正在播放＆＃34;记录＆＃34;单击按钮。传递一个布尔变量，显示录制是否已开始。生成意图的代码是：

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。收到意图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时的值相同，但是当我得到它时，它的值不一样。

@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();

}

我还测试了实际意图而不是阴影，但结果相同

Answer 1

使用get（）而不是getBoolean（）为我工作。

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();

}

Answer 2

这可能对原始的，但未来的人没有帮助：如果您碰巧发现自己处于这种情况 - 首先检查您的常量和意图过滤器是否截然不同，以便接收者不会收到无意的广播。有好几次我花的时间比我更愿意承认这个问题！

在 Robolectri 中

shadowOf(ApplicationProvider.<Application>getApplicationContext()).getBroadcastIntents();

如何测试已广播的意图
