Robolectric 2.0 在测试时不创建 View

Question

我正在尝试使用 robolectric 和 roboguice 进行测试。我已成功注入(inject)和测试类，但是当我尝试测试事件时，我似乎无法在测试环境中创建 View 对象

我收到以下错误

testAttemptsLoginWhenSignInButtonIsClicked(com.clearc2.HomeActivityTest) Time elapsed: 2.234 sec <<< ERROR! java.lang.RuntimeException: Failed to create a android.widget.EditText at

发现了问题。 Robolectric 不喜欢在我的密码 EditText 上设置的 android ime 选项。一旦我删除了这些行，测试就会按预期运行。
