右键该项目，选择property然后选择java build path， 选择 Add External JARs，选择下到的robotium.jar
　　在跑测试用例之前，还需要修改下AndroidManifest.xml文件的android:targetPackage为被测应用的根的包名
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mitalk.test"
android:versionCode="1"
android:versionName="1.0" >
<supports-screens android:anyDensity="true" />
<uses-sdk android:targetSdkVersion="17" />
<uses-sdk android:minSdkVersion="17" />
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:targetPackage="com.tencent.mm" />
<application
android:debuggable="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<uses-library android:name="android.test.runner" />
</application>
</manifest>
　　以上都弄完了，run as android junit test，可以跑了
　　备注：另外的运行方式：
Test can also be run using command prompt/terminal by following simple steps
* Write following command to install AndroidCalculator apk on emulator
> adb install <path>/AndroidCalculator.apk
* Write following command to install AndroidCalculatorTest apk on emulator
> adb install <path>/AndroidCalculatorTestApk.apk
* Run the test cases:
> adb shell am instrument -w com.testcalculator/android.test.InstrumentationTestRunner
