Steps for writing test code in Android engineering

The first step: Write a class to inherit Androidtestcase

 Public class extends Androidtestcase

and write a test method,

Note that the method to be tested must be public void, and the method cannot receive any parameter information

1  Public void Testinsert () {2 }

Step Two: Add the instruction set used in the manifest file, and the class library to use

  <!-- specifying the target application  to be tested by the package life  -    < Instrumentation         Android:name = "Android.test.InstrumentationTestRunner"         android:targetpackage= "Com.itheima.studentsystem"></ Instrumentation >

You also need to add uses-library under the application element.

<!-- use to this class library    -       <  android:name= "Android.test.runner"/>

Step three: Run the test method (right-click Run as Android Junit Test)

public void Testadd () {}
