如何覆盖Robolectric应用？

Question

我继承了遗留的Android项目并开始添加Robolectric 3和JUnit 4测试用例.遗憾的是,目前主要的Application类无法初始化,因为意大利面条代码和框架在Robolectric中不起作用.我想替换我的应用程序类进行测试.但在我甚至可以更新RuntimeEnviroment.application变量之前,Robolectric崩溃了.有没有办法在Robolectric中禁用清单应用程序创建？

这是我一直在努力做的事情:

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class, sdk = 21, manifest = Config.NONE)
public class TestClass {
    @Before
    public void setUp() {
        RuntimeEnvironment.application = new Application();
    }

    @Test
    public void testFunc() {
        // some testing goes here
    }
}

但由于Parse框架,它失败了:

Answer 1

因此,Robolectric开发人员发现了这种情况并且@Config指令允许应用程序覆盖.另外,显示覆盖对我没有任何帮助,因此可以将其删除.

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class, sdk = 21, application = MyTestApplication.class)
public class TestClass {
    @Test
    public void testFunc() {
        // some testing goes here
    }
}

由于我们的应用程序使用单例模式,我还必须初始化单例实例.我忽略了对purpouse的所有其他初始化,因为它主要是在框架中.这是我的MyTestApplication的样子:

public class MyTestApplication extends MyApplication {
    @Override
    public void onCreate() {
        MyApplication.instance = this;
    }
}
