我正在尝试进行浓缩咖啡测试，但我不断收到此错误：
INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{com.mikeestrada.test/android.test.InstrumentationTestRunner}
它工作过一次，但我无法正确重新创建报告。他们只是空白，没有测试任何东西。我尝试了很多命令，包括
adb shell am instrument -w -r com.mikeestrada.test/android.test.InstrumentationTestRunner
和
adb shell am instrument -w -r com.mikeestrada.test/com.google.android.apps.common.testing.testrunner.GoogleInstrumentation TestRunner
这是我的代码片段：

构建.gradle

如果它意味着什么 -<instrumentation>清单中的属性被涂成红色，就好像 IntelliJ 无法识别它们一样。
任何帮助都很棒，谢谢！
