TL:DR
我正在寻找一种方法来确保我们的 Instrumentation 测试套件可以编译，但无需实际运行它。是否可以使用Gradle的Android插件来实现？
我查看了official documentation，除了编译然后一起运行测试的 Gradle 命令之外，我没有看到任何其他内容。
我正在寻找这个的原因是我们希望能够在每个 Pull Request 上运行构建，但运行套件需要太长时间。然而，我们希望确保检测套件至少可以编译所有代码更改，以便它能够及时运行。
感谢您的帮助

可以实现，gradle是把一切都作为task运行，希望你在执行：
./gradlew test
你可以看到输出为
Incremental java compilation is an incubating feature.

BUILD SUCCESSFUL
这是任务调用层次结构，意味着任务“test”依赖于所有或一个以上任务，即“app:testReleaseUnitTest”。所以你可以调用“assembleReleaseUnitTest”
./gradlew assembleReleaseUnitTest
【讨论】：
找到了Gradle 任务来实现这一点：
$ ./gradlew compileDebugAndroidTestJavaWithJavac
上面的任务将编译 Instrumented 测试而不实际运行它们。
