android - java.lang.RuntimeException : Stub! 在Android 项目中运行Junit

Question

在一个 android 项目中，我尝试运行简单的 junit 测试。他们总是失败:

java.lang.RuntimeException: Stub!
at org.apache.http.impl.client.AbstractHttpClient.<init>(AbstractHttpClient.java:5)
at org.apache.http.impl.client.DefaultHttpClient.<init>(DefaultHttpClient.java:7)
at com.my.android.JsonParser.getJSONFromUrl(JsonParser.java:27)
at com.my.android.test.JsonParser_Test.getJson(JsonParser_Test.java:19)

这是它失败的行，任何新的类启动都会这样做。

 public JSONObject getJSONFromUrl(String url) {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        ...
 }

在几篇文章中，我发现 junit jar 应该包含在 Android SDK 之前。我在 IntelliJ 中做到了这一点，但我没有帮助。我正在使用 junit 4.9 和 Android SDK 4.2.2

我认为 robolectric 对您很有用。

Running tests on an Android emulator or device is slow! Building, deploying, and launching the app often takes a minute or more. That’s no way to do TDD. There must be a better way.

Wouldn’t it be nice to run your Android tests directly from inside your IDE? Perhaps you’ve tried, and been thwarted by the dreaded 'java.lang.RuntimeException: Stub!'?
