我正在尝试在Android的Robolectric测试中注入一个Mockito模拟器。这是我的代码
public class RoboGradleTestRunner extends RobolectricTestRunner {
public RoboGradleTestRunner(Class<?> testClass) throws InitializationError {
super(testClass);
}
@Override
protected Class<? extends TestLifecycle> getTestLifecycleClass() {
return TestLifeCycleWithInjection.class;
}
@Override
protected AndroidManifest getAppManifest(Config config) {
String manifestProperty = System.getProperty("android.manifest");
if (config.manifest().equals(Config.DEFAULT) && manifestProperty != null) {
String resProperty = System.getProperty("android.resources");
String assetsProperty = System.getProperty("android.assets");
return new AndroidManifest(Fs.fileFromPath(manifestProperty),
Fs.fileFromPath(resProperty),
Fs.fileFromPath(assetsProperty));
}
return super.getAppManifest(config);
}
public static class TestLifeCycleWithInjection extends DefaultTestLifecycle {
@Override
public void prepareTest(Object test) {
super.prepareTest(test);
TestApplication application = (TestApplication) Robolectric.application;
MockitoAnnotations.initMocks(test);
Injector.inject(test);
}
}
}
@RunWith(RoboGradleTestRunner.class)
public class SomeTest {
@Before
public void setUp() {
injectMocks(this);
}
@Inject
MyModel myModel;
@Test
public void testThatICanInject() {
JsonObject params = new JsonObject();
verify(apiClient).request(Request.Method.POST,
"/oauth/token.json",
params);
myModel.login(params);
}
}

BUILD FAILED
答案 0 :(得分：0)
我最后说了一下，然后回到Robolectric 2.1并使用了Jake Wharton的插件版本。工作得更好。如果需要，请向我询问。
