How does it work

• Shadow object
• View and resource loading

New Resource :

• Unit testing support
• Android Studio 1.1.0 (Beta 4) and Robolectric 2.4
• Robolectric Installation for Unit Testing

目前在網路上的 Android Studio unit test 的範例可以說是少得可憐，尤其是 Android Studio 和 Gradle 這兩個大傢伙不斷低更新，要找到比較符合現狀的組合又更少了。

android-unit-test 和 android-studio-unit-test-plugin 這兩個 repo 來設置 Robolectric 是我目前看到最簡單的設定。

建置環境：

• OS X 10.10.2
• JDK 1.7.0_71
• Adnroid Studio RC 1
• Gradle 2.1 (應該不重要)
