Build an android unit test environment

We often write many methods when writing an activity. In order to enable our method to implement our function, we need to perform unit test first. So every time we develop an activity, first, we need to build a unit test environment.

Methods:

1. When creating a class, it inherits from androidtestcase

2. Add the following two pieces of code to the manifest. xml file:

<uses-library android:name="android.test.runner"
/>// Introduce the Test Library and place it in the application

<! -- Indicates the name of the target package and instrumentation to be tested. --

< instrumentation
android:targetPackage = "Packages to be tested"Android: Name = "android.test.InstrumentationTestRunner"
/>   3. Write the method of the target method to be tested.   Based on the above three points, you can build a unit test environment.
