In Part 2, I had gone through the Robolectric set up and a simple example showing how to write unit test using Robolectric. Application Since most Android code is centric around the Context, getting hold of your application's context is a typical task for most tests. @felipecsl does indeed unblock immediate issues, but seeing as the support library authors clearly believed they had properly handled Robolectric as a special case, it might warrant taking a look at why their initial workaround doesn't work. The context we're using is an Activity instance created with Robolectric. I didn't investigate how to replicate that behavior in our test runner with 2.x (and it seems likely to change anyway), but many of these shadowed classes to the 1.x support for run-time checks for hardcoded strings in i18n-sensitive methods. And last but . RobolectricではShadowという仕組みでMockクラスを用意することができます。. The context we're using is an Activity instance created with Robolectric.

It has a specific JUnitRunner class for running unit tests in the test package with shadow classes for Android objects like application context. March 27, 2014. If you are starting a new project, we would recommend Gradle first (since it is the build system of choice in Android Studio) and Bazel second. Data read from the source input stream is. I worked with the same problem, and the only solution I found was that I needed to develop the Robolectric project and add ShadowSQLiteOpenHelper .

If you are starting a new project, we would recommend Gradle first (since it is the build system of choice in Android Studio) and Bazel second. This means when your tests or code under test calls into the Android framework you get a more realistic experience as for the most part the same code is executed as would be on a real device. I don't know enough about the internals of Robolectric to say if the support lib's approach was wrong for the start, or did work in some cases and not others. We also compare it with the drawable we expect to see. When I modified the data binding between api and UI or Sqlite, then I will only run Robolectric. And then our clazz variable or the class. org.robolectric.shadow.api.Shadow. 2 Shadow Classes, rewritten android core libraries by Robolectric, are the real magic of Robolectric.
