android - 当 imageuri 作为额外传递时，Espresso 测试相机 Intent

Question

我需要通过在 intent extra 中提供的路径上创建一个图像文件来 stub 相机 intent。Espresso 只能响应 activityresult。我在哪里可以执行操作以从 intent extra 传递的路径创建文件。

启动相机代码

File destination = new File(Environment.getExternalStorageDirectory(), "app_name" + System.currentTimeMillis() + ".jpg");



<p>imageUri = FileProvider.getUriForFile(getApplicationContext(), getApplicationContext().getPackageName() + ".fileprovider", destination);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);</p>



startActivityForResult(intent, AppConstants.REQUEST_CODE_CAMERA);

在测试中 stub Intent 的代码

Instrumentation.ActivityResult result = new Instrumentation.ActivityResult(Activity.RESULT_OK, null);
intending(hasAction(MediaStore.ACTION_IMAGE_CAPTURE)).respondWith(result);

Ismael 的回答很完美。对于那些在 Java 中寻找解决方案的人，这里是。

intending(hasAction(MediaStore.ACTION_IMAGE_CAPTURE)).respondWith(
            new Instrumentation.ActivityResult(Activity.RESULT_OK, null));

IntentCallback intentCallback = new IntentCallback() {
        @Override
        public void onIntentSent(Intent intent) {
            if (intent.getAction().equals("android.media.action.IMAGE_CAPTURE")) {
                try {
                    Uri imageUri = intent.getParcelableExtra(MediaStore.EXTRA_OUTPUT);
                    Context context = InstrumentationRegistry.getTargetContext();
                    Bitmap icon = BitmapFactory.decodeResource(
                            context.getResources(),
                            R.mipmap.ic_launcher);
                    OutputStream out = getTargetContext().getContentResolver().openOutputStream(imageUri);
                    icon.compress(Bitmap.CompressFormat.JPEG, 100, out);
                    out.flush();
                    out.close();
                } catch (IOException e) {
                    GenericUtility.handleException(e);
                }
            }
        }
    };
    IntentMonitorRegistry.getInstance().addIntentCallback(intentCallback);

 //Perform action here
 onView(withId(R.id.tv_take_photo)).perform(click());
