Android Unit Test junit Configuration and usage

Now integrated ADT Post Eclipse can create Android Test Project directly

：

Select the unit you want to test after naming, for example, I am ready to test SMS, I can choose

I built a new test project for Junitsms

I want to test the Testapp.java next simplest function in the SMS project

 1  public  class   TestApp { 3  public  int  Add (int  a, b)  4   { 5  int  sum=a+B;  6  return   sum;  7   8  }

Create a new test class apptest and inherit the Androidtestcase class, write a test method, and use assert assert within the test method to test the method to be tested.

Add the following code after the creation is successful

1  Packagecom.example.sms.test;2 3 ImportJunit.framework.Assert;4 ImportCmo.example.test.testapp;5 Importandroid.test.AndroidTestCase;6 ImportAndroid.util.Log;7 8  Public classApptestextendsAndroidtestcase {9     Private Static FinalString tag= "Apptest";Ten      One      Public voidAppshow ()throwsthrowable{ A          -TestApp tp=NewTestApp (); -         intRslt=tp.add (3, 7); theAssert.assertequals (10, rslt); -LOG.I (Tag, "Appshow");  -     } -  +  -}

To join log is to learn to view and output the log information, and then select the method in the right outline area run as-->android Junit Test

If the test is normal,

But if you change the Apptest.java to

Assert.assertequals (one, rslt);

Re-test run the following results
