当图像传递为额外时,Espresso测试相机意图

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保持相机意图.浓缩咖啡只能响应活动结果.我在哪里可以执行操作以从intent extra传递路径创建文件.

启动相机的代码

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

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

startActivityForResult(intent, AppConstants.REQUEST_CODE_CAMERA);

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

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

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

startActivityForResult(intent, AppConstants.REQUEST_CODE_CAMERA);

在测试中存根意图的代码

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

伊斯梅尔的回答是完美的.对于那些在java中寻找解决方案的人来说,就是这样.

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());

您需要创建一个IntentCallback来拦截该Uri值并在那里保存样本图像.

Kotlin中的样品

  intentCallback = IntentCallback {
        if (it.action == "android.media.action.IMAGE_CAPTURE") {
            it.extras.getParcelable<Uri>("output").run {
                val inStream = Resources.getResource(sampleImageFileName).openStream()
                val outStream = activity.contentResolver.openOutputStream(this)
                ByteStreams.copy(inStream, outStream)
            }
        }
    }

您需要在意图触发事件之前注册回调

  IntentMonitorRegistry.getInstance().addIntentCallback(intentCallback)

不要忘记最后取消注册

  IntentMonitorRegistry.getInstance().removeIntentCallback(intentCallback)
