Ii. Use of robotium

1. Download the JAR file of robotium

Download the required JAR file at the address below

Http://code.google.com/p/robotium/downloads/list

I downloaded a jar package of 4.0.

2. Create a test project

2. Select Android test project and select an existing project to test. In the project list below, select the project to be tested.

3. Enter the package name, select the SDK version, and click Finish to create the project. The directory structure of the test project is as follows:

4. Create a test class. After creating this class, import the JAR file of robotium we downloaded before to the project.

package com.android.hello.test;import com.android.hello.HelloActivity;import com.jayway.android.robotium.solo.Solo;import android.test.ActivityInstrumentationTestCase2;public class TestScript  extends ActivityInstrumentationTestCase2<HelloActivity>{private Solo mSolo;public TestScript() {super("com.android.hello", HelloActivity.class);// TODO Auto-generated constructor stub}public void setUp(){mSolo=new Solo(getInstrumentation(), getActivity());}public void testText(){boolean expected =true;System.out.println("mSolo============"+mSolo);boolean actual =mSolo.searchText("Hello") &&mSolo.searchText("World");assertEquals("The text  have not found", expected, actual);}}

The purpose of this test class is to check whether there are two texts in the main interface: Hello and world.

5. The test results are as follows:

Iii. Common Errors During use

1. the prompt "Java. Lang. noclassdeffounderror: COM/jayway/Android/robobench/Solo" is displayed.

The specific code is as follows:

java.lang.NoClassDefFoundError: com/jayway/android/robotium/solo/Soloat java.lang.Class.getDeclaredFields(Native Method)at java.lang.Class.getDeclaredFields(Class.java:647)at android.test.ActivityTestCase.scrubClass(ActivityTestCase.java:63)at android.test.ActivityInstrumentationTestCase2.tearDown(ActivityInstrumentationTestCase2.java:172)at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:169)at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:154)at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:545)at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1551)Caused by: java.lang.ClassNotFoundException: com.jayway.android.robotium.solo.Soloat dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:61)at java.lang.ClassLoader.loadClass(ClassLoader.java:501)at java.lang.ClassLoader.loadClass(ClassLoader.java:461)... 13 more

I didn't find the solo class.

Right-click the hellotest project file ------- properties ----------- Java build path ----- libraries Delete the android dependencies and robotium-solo-4.0.jar inside and then re-import the robotium-solo-4.0.jar.

Select All --- OK on the order and export interface.

Click project option ------ Clean Project in the toolbar.

For example

 

 

2. a null pointer is reported, prompting that msolo is null.

Check that the setup method name is case sensitive. Otherwise, the code in the method will not be executed.
