Test running failed: Unable to find instrumentation info for: ComponentInfo

在使用android studio进行单元测试的时候报错

Test running failed: Unable to find instrumentation info for: ComponentInfo{top.ljaer.www.phonemanager.test/android.test.InstrumentationTestRunner}
Empty test suite.

解决方法

点击Edit Configurations进行编辑

将Specific instrumentation runner改为com.android.test.runner.MultiDexTestRunner

再次点击运行

单元测试正常

$ adb shell am instrument -w -r   -e debug false -e class top.ljaer.www.phonemanager.BlackNumTest#testQueryAllBlackNum top.ljaer.www.phonemanager.test/com.android.test.runner.MultiDexTestRunner
