Android檢測測試失敗，出現''java.lang.NoClassDefFoundError'空測試套件'。

Question

之後我加testCoverageEnabled = true到debug構建類型我的儀器測試開始失敗，並顯示消息Started running tests Test running failed: Instrumentation run failed due to 'java.lang.NoClassDefFoundError' Empty test suite. testCoverageEnabled = false奇怪的一切都是有效的。

這裏是我的build.gradle

嘗試增加在app/build.gradle

sourceSets { 
    main { 
     assets.srcDirs = ['assets', 'src/main/assets', 'src/main/assets/fonts'] 
     java.srcDirs = ['src/main/java', 'src/instrumentTest', 'src/instrumentTest/java', 'src/test/java'] 
    } 
    test { 
     java.srcDirs = ['src/test/java', 'src/test/java/'] 
     resources.srcDirs = ['src/test/resources'] 
    } 
}
