如何使用gradle wrapper 2.2.1从命令行运行单个单元测试

Question

使用带有gradle包装器版本2.2.1的Android工作室,我试图在一个单独的测试类中运行所有测试,以及该类中的特定测试并尝试使用:

./gradlew  test --tests DownloadsActivityTest

像文档建议,以及

-DandroidTest.single=DownloadsActivityTest

但这些版本都不起作用.

如何使用gradle包装器从命令行运行单个测试类和单个测试？

 ./gradlew --version

Answer 1

要仅在特定测试类中运行检测测试(androidTests),请执行:

./gradlew app:connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=com.example.android.testing.blueprint.ui.espresso.EspressoTest

要仅在特定测试类或包中运行本地测试("单元",JVM测试),请执行:

./gradlew :app:testDebugUnitTest --tests "com.example.android.testing.blueprint.unit.integrationTests.*"

Answer 2

./gradlew :<module name>:test<CapitalCasedBuildVariant> --tests "<Test name pattern>"

指定测试所在的模块名称非常重要,否则,当gradle构建依赖模块时,它将尝试测试它们,并且可能会失败,因为所有测试都不符合测试模式:

No tests found for given includes: [FooTest]

此外,除非您指定测试的完全限定名(FQN),否则您的测试名称模式应以a开头*.

在我的例子中,我有一个名为的模块app和一个名为的变体localDebug,我想测试FooTest,所以我运行:

./gradlew :app:testLocalDebug --tests "*FooTest"

Answer 3

Android Gradle 插件从 1.0.0 开始，不支持运行单个 Android 测试。其功能请求提交于https://code.google.com/p/android/issues/detail?id=74196。

我知道更好的测试支持总体上在 1.0 后的优先级列表中非常重要，但我不能肯定地说何时会实现这一点。
