如何覆蓋Robolectric應用程序？

Question

我已經繼承了舊版Android項目並開始添加Robolectric 3和JUnit 4測試用例。可悲的是，目前主要的Application類不能被初始化，因爲意大利麪代碼和框架在Robolectric中不起作用。我想替換測試的應用程序類。但Robolectric崩潰之前，我甚至可以更新RuntimeEnviroment.application變量。 有沒有辦法在Robolectric中禁用清單應用程序的創建？

這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 
    } 
} 

但由於失敗解析框架：

Answer 1

所以它發生Robolectric開發商forsaw這種情況，並@Config指令允許應用程序覆蓋。另外顯示覆蓋並沒有幫助我，所以它可以被刪除。

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

由於我們的應用程序使用單例模式，我還必須初始化單例實例。我忽略了所有其他關於purpouse的初始化，因爲它大多是在啓動框架。以下是我的MyTestApplication的樣子：

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

Answer 2

有一個更簡單的解決方案。

只需在測試源中放置一個類Test<YouApplicationName> ** ** Robolectric將會拿起它。

所以，如果您的應用程序的名稱是org.my.package.SuperApplication然後在文件夾中創建test\java\org\my\package\類TestSuperapplication，你並不需要提供在@Config部分東西。
