安卓测试 : No tests found

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).

所以我在我的 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。但大多数时候我得到这个。

Answer 1

对我来说，这发生在仪器测试的测试运行器错误时。我变了

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

至

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

请注意，我使用了 KTS (build.gradle.kts)，但这对问题没有影响，只是语法略有不同。
