带有 SelectClasses 的 Junit5 testSuite 在 android 单元测试中不起作用

Question

我正在尝试为 android 应用程序的单元测试创​​建一个测试套件，但它总是因不同类型的配置错误而失败，其中之一如下，

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':appModules:factList:testDebugUnitTest'.
> No tests found for given includes: [reprator.wipro.factlist.FactListTestSuite] 
 (filter.includeTestsMatching)

回购详情：https://github.com/TheReprator/Wipro/tree/junit5

分支：junit5

TestSuite 类：https://github.com/TheReprator/Wipro/blob/junit5/appModules/factList/src/test/kotlin/reprator/wipro/factlist/FactListTestSuite.kt

我尝试了很多努力和参考，其中一些如下，

1. Link 1
2. Link 2

我的整个代码与 master 分支中的 junit4 完美配合。

请帮忙。

Answer 1

我看到您正在使用@RunWith(JUnitPlatform::class)，它基本上说“嘿，请 JUnit5，运行我的 JUnit 4 测试！”但是你使用了org.junit.jupiter.api.Test 注释，它告诉平台这些是JUnit5 测试。

所以实际上，没有要运行的 JUnit 4 测试。

我建议您完全放弃套件，如果您希望测试套件使用嵌套类。或者使用Tag 注解对测试进行分组。

默认情况下，JUnit5 将运行您在测试源路径中拥有的所有 @Test 方法。检查你的 gradle 配置。

Answer 2

您是否使用 gradle 来运行测试？因为我下载了你的分支，在没有 android studio 的情况下设置了一个环境（我的个人电脑没有安装开发环境），我在你的 JUnit 5 分支上得到了这个输出：

./gradlew appModules:factList:test --rerun-tasks

FactListDataRepositoryImplTest > get fact list from server, on internet connection available() PASSED

FactListDataRepositoryImplTest > No internet available() PASSED

FactListApiServiceTest > get fact list request check() PASSED

FactListApiServiceTest > Timeout example() PASSED

FactListApiServiceTest > get fact list successfully() PASSED

FactListRemoteDataSourceImplTest > fetch list successfully from server and map it to UI pojo() PASSED

FactListRemoteDataSourceImplTest > fetch list failed with errorBody() PASSED

FactListMapperTest > create the parsed json fact into FactModals class with title() PASSED

FactListUseCaseTest > fetch factlist from remote data source() PASSED

FactListUseCaseTest > failed to load data, as internet is not available() PASSED

FactListViewModalTest > onRefresh, getlist successfully() PASSED

FactListViewModalTest > retry, getFactlist successfully() PASSED

FactListViewModalTest > get factList fetch failed on launch() PASSED

FactListViewModalTest > get factList successfully on launch() PASSED

也许您需要将构建操作委托给 gradle（在 IntelliJ 上可能，在 Android Studio 上不确定）或清除您的项目设置或类似的东西。

您可能正在尝试使用运行您的套件的Run Configuration，这是一个 JUnit4 套件，需要 JUnit4 测试，但您的测试是 JUnit5 测试。
