在Android中测试通知

Question

My android app has a service which sends notifications to user based on parameters like number of runs of the app. The notifications are sent at different times in different situations. I want to test whether notifications are sent at the right times in all the different cases. Does android provide a way of such a testing ?

Answer 1

Testing Notification using UIAutomator:

Just go through the below code. It will help you in testing the notification.

UiDevice device = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
device.openNotification();
device.wait(Until.hasObject(By.text(NOTIFICATION_TITLE)), TIMEOUT);
UiObject2 title = device.findObject(By.text(NOTIFICATION_TITLE));
UiObject2 text = device.findObject(By.text(NOTIFICATION_TEXT));
assertEquals(NOTIFICATION_TITLE, title.getText());
assertEquals(NOTIFICATION_TEXT, text.getText());
title.click();
device.wait(Until.hasObject(By.text(ESPRESSO.getName())), TIMEOUT);

Don't forget to add the UIAutomator dependencies in build.gradle .

// UIAutomator dependency
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.1'

Here is a nice explanation of this topic:

Espresso for Android is perfect and fast test automation framework, but it has one important limitation - you are allowed to operate only inside your app under test context.

This means, it is not possible to automate tests for app features such as:

• application push notifications
• contact synchronization
• navigating from another app to your app under test,

Since you have to deal with other apps from the mobile device - NotificationBar , Contacts or People app, etc.

In fact it wasn't possible until the release of UIAutomator 2.0 . As stated in Android Developers blog post - "...Most importantly, UI Automator is now based on Android Instrumentation...". And because of that we can run UIAutomator tests as well as Espresso tests using Instrumentation test runner .

In addition to that we can combine UIAutomator tests together with Espresso tests and this gives us the real power and control over the phone and application under test.
