[英]Robolectric Unit Test throws Exception
我是整個測試工作的初學者。 我想用Robolectic建立一個活動,但是如果我運行測試,它總是會拋出NullPointerException
我的測試設置
@RunWith(RobolectricTestRunner.class)
@Config(constants = BuildConfig.class)
public class HomeActivityTest {
private HomeActivity activity;
@Before
public void setup() throws Exception{
activity = Robolectric.buildActivity(HomeActivity.class)
.create()
.resume()
.get();
}
我的StackTrace
java.lang.NullPointerException

我已經嘗試過該解決方案,但Android Studio 2.3更新失敗了,但它對我不起作用。
我昨天在升級我的一個舊項目的部門時遇到了這個問題。 原來在robolectric 3.3+中添加了“與工具鏈更緊密的集成”。 對我來說,解決方法是執行robolectric的“入門”頁面( http://robolectric.org/getting-started/ )的build.gradle
,並將以下內容添加到我的應用程序的build.gradle
文件中。
android {
testOptions {
unitTests {
includeAndroidResources = true
}
}
}
