Robolectric filenotFound在资产文件上

Question

您好我正在使用robolectric版本3.0对我的应用进行单元测试，并且在src / test / assets下有一些文件，其中包含一些文件但仍然获取fileNotFound。

这是我的测试代码：

```

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class, manifest = Config.NONE)
public class ShowsDatesTest {

@Test
public void testResponse(){
BufferedReader = getBufferedResponseFromFile("response.json");
}

private BufferedReader getBufferedResponseFromFile(String json) throws IOException {

         mContext = RuntimeEnvironment.application;
        InputStream jsonResponse = mContext.getAssets().open(json);

        BufferedReader br = new BufferedReader(new InputStreamReader(jsonResponse, "UTF-8"));

        return br;

    }

}

```

这是我的gradle文件中的源集和依赖项： ```

 production {
            res.srcDir 'build-config/production/res'
            test.java.srcDirs += 'src/main/java'
            test.java.srcDirs += "build/generated/source/r/production"
            test.java.srcDirs += "build/generated/source/buildConfig/production"
            test.assets.srcDir file('src/test/assets')
        }

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.1.+'
