Android 测试：未找到测试

Question

Starting 0 tests on test(AVD) - 10
Tests on test(AVD) - 10 failed: Instrumentation run failed due to 'Process crashed.'

com.android.build.gradle.internal.testing.ConnectedDevice > No tests found.[test(AVD) - 10] FAILED 
No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test annotations).

所以我在 CI 上运行测试，这个错误随机弹出，有时它会找到 2 个测试并运行它。但大多数时候我都会得到这个。

Answer 1

对我来说，当仪器测试的测试运行程序错误时，就会发生这种情况。我变了

android {
    // ...
    testInstrumentationRunner = "android.support.test.runner.AndroidJUnitRunner"
    // ...
}

到

android {
    // ...
    testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    // ...
}

请注意，我使用了 KTS ( build.gradle.kts )，但这对于问题来说并不重要，语法只是略有不同。
