java - 如何在同一 Activity 中同步运行 Espresso 测试套件测试类？

Question

我想同步运行一组测试。理想情况下，我希望将这些测试集模块化为单独的类，因为将它们合并为 1 个类将导致文件太大。例如，我有以下测试套件文件:

@RunWith(Suite.class)
@Suite.SuiteClasses({
        LoginTest.class,
        AddItemsTest.class,
        ItemTest.class,
        ArchiveTest.class,
        LogoutTest.class
})
public class FullTest{}

这些测试用例按顺序运行，但是我对继续在这些测试用例之间使用相同的上下文和 Activity 感到困惑。我在运行测试时遇到错误，没有找到 Activity ...

E/TestRunner: failed: runAddItems(com.XXX.XXX.functional.TestSuite.AddItemsTest)
    ----- begin exception -----
E/TestRunner: java.lang.RuntimeException: No activities found. Did you forget to launch the activity by calling getActivity() or startActivitySync or similar?

我需要做什么特定的事情才能继续我在上一个测试用例中停止的工作流程？

我认为这不是一个有效的解决方案，但我想通了。我只是创建一个单独的 Test 类，并在我的测试中创建它的一个实例。这有效。
