Android使用Robotium自动化测试junit生成单元测试结果报告

ゝ一世哀愁。 2022-09-24 01:27 273阅读 0赞

junit-report包下载地址：https://github.com/jsankey/android-junit-report/downloads

1、添加测试包到被测工程的lib下，Build Path---Add to Build Path

2、修改android的AndroidManifest文件，将

<instrumentation  
        android:name="android.test.InstrumentationTestRunner"

修改为

<instrumentation  
        android:name="com.zutubi.android.junitreport.JUnitReportTestRunner"

3、修改执行参数右键工程：Run As---Run Configurations

下拉选择修改为com.zutubi.android.junitreport.JUnitReportTestRunner

4、1运行Android JUnit Test，跑完测试用例后会在被测工程的文件夹下的files文件夹中生成junit-report.xml文件（/data/data/被测包名/files/junit-report.xml）

4、2如果不使用Android JUnit Test，则按如下方式运行，注意修改

adb shell am instrument -e class com.netease.mobile.autotest.testing.LoginTest\#testLogin -w com.netease.mobile.autotest/com.zutubi.android.junitreport.JUnitReportTestRunner

adb shell am instrument -e class com.netease.mobile.autotest.testing.LoginTest\#testUnLogin -w com.netease.mobile.autotest/com.zutubi.android.junitreport.JUnitReportTestRunner

5、adb pull /data/data/(your app package name)/files/junit-report.xml e:/

如果要修改结果保存地址，需要重写类InstrumentationTestRunner
