android - 使用自定义运行器时未找到测试

Question

我在我的项目中使用 androidx.test 库(我最近迁移到了该库)并使用自定义 AndroidJUnitRunner。 迁移之前一切正常，但现在出现此错误 -

开始运行测试 测试运行失败:由于“进程崩溃”，检测运行失败。 空测试套件。

我使用的自定义运行器类扩展自 androidx.test.runner.AndroidJUnitRunner

在我的应用 build.gradle 文件中，我有以下设置 -

testInstrumentationRunner“com.example.CustomTestRunner”

具有依赖性-

androidTestImplementation“androidx.test.ext:junit:1.1.0” androidTestImplementation 'androidx.test:runner:1.1.1' androidTestImplementation 'androidx.test:core:1.1.0' androidTestImplementation“androidx.test:rules:1.1.1”

我所有的测试类都有@RunWith(androidx.test.ext.junit.runners.AndroidJUnit4.class)

我卡在这了。任何帮助，将不胜感激。 谢谢。

Answer 1

我在使用 Android 4.4 进行测试时看到了这个 当我切换到 Android 6 (SDK 23) 时，问题就消失了。

我使用了 androidx.test.ext.junit.runners.AndroidJUnit4 对于我的仪器测试@RunWith(AndroidJunit4.class)

但我的 testInstrumentationRunner 使用包:

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

混合两个不同的包看起来很奇怪，但它确实有效。

我的 app/build.gradle 有:

android {
    defaultConfig {
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    testOptions { 
        execution 'ANDROIDX_TEST_ORCHESTRATOR'
        unitTests {
            includeAndroidResources = true
        }
    }

    useLibrary 'android.test.runner'
    useLibrary 'android.test.base'
    useLibrary 'android.test.mock'
}
