小编Dra*_*ake的帖子

我正在尝试为我的SignIn Activity编写测试,其中我正在使用AsyncTask.

public class SignInActivity extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {

    .........

    new AsyncSignButton().execute();
}

class AsyncSignButton extends AsyncTask<Void, Void, Integer>{
   ....... 
}

为了测试,我尝试过使用IdlingResource,但我不明白如何将它与AsyncTask一起使用,而不是像示例中那样使用WebView,只是简单的AsyncTask.

这是我的测试代码:

public class Test extends ActivityInstrumentationTestCase2<SplashActivity> {

private SplashActivity mActivity;

public Test(){
    super(SplashActivity.class);
}

public Test(Class<SplashActivity> activityClass) {
    super(activityClass);
}

@Override
protected void setUp() throws Exception{
    super.setUp();
    mActivity = getActivity();
    //how call it?
}

@LargeTest
public void testList() throws InterruptedException {

   //wait AsyncTask before call
   onView(withId(R.id.action_bar_accept_button)).perform(click());

}

public final class AsyncIdlingResource implements IdlingResource { …

如何使用枚举将JSON解析为模型？

这是我的枚举类:

enum class VehicleEnumEntity(val value: String) {
   CAR("vehicle"),
   MOTORCYCLE("motorcycle"),
   VAN("van"),
   MOTORHOME("motorhome"),
   OTHER("other")
}

我需要解析type一个枚举

"vehicle":{"data":{"type":"vehicle","id":"F9dubDYLYN"}}

我已经尝试过标准方法,只需将我的枚举传递给POJO,它总是为空

如何在RecyclerView使用中创建动态列数StaggeredGridLayoutManager.我已经有工作了RecyclerView.这是我需要做的屏幕:

我进行了浓缩咖啡测试，希望应用程序在测试完成后保持准确的活动。我需要继续与应用程序交互。

@SmallTest
public void testOpenNavigationDrawer()
{
    Espresso.onView(ViewMatchers.withId(com.eleks.espresso.example.app.R.id.content_frame)).perform(ViewActions.swipeRight());
    ListView lvDrawerMenu = (ListView) getActivity().findViewById(com.eleks.espresso.example.app.R.id.lvDrawerMenu);
    Preconditions.checkNotNull(lvDrawerMenu, "lvDrawerMenu is null");
    final int count = lvDrawerMenu.getAdapter().getCount();
    Preconditions.checkPositionIndex(2, count, "No 1 index " + count + " size");
    Object obj = lvDrawerMenu.getItemAtPosition(2);
    Espresso.onView(Matchers.allOf(ViewMatchers.withId(com.eleks.espresso.example.app.R.id.tvItem), ViewMatchers.hasSibling(ViewMatchers.withText(obj.toString())))).perform(ViewActions.click());
}

我怎样才能做到这一点？谢谢你！

如何在Espresso测试中打开标签？我试着做Espresso.onView(ViewMatchers.withId(R.id.practice_results_tab)).perform(ViewActions.click());,但那不起作用.在该代码中,我打开了此选项卡的布局.有XML文件:

    <TabHost
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/practice_tabHost">

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical">

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content">
            </TabWidget>

            <FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent">

                <LinearLayout
                    android:id="@+id/practice_settings_tab"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:orientation="vertical">

                </LinearLayout>

                <LinearLayout
                    android:id="@+id/practice_results_tab"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:orientation="vertical">

                </LinearLayout>
            </FrameLayout>
        </LinearLayout>
    </TabHost>

我应该使用什么ID来打开标签？

logcat中的错误:

Caused by: java.lang.RuntimeException: Action will not be performed because the target     view does not match one or more of the following constraints:
at least 90 percent of the view's area is displayed to the user.

我用Retrofit 2,okhttp和okhttp:logging-interceptor创建了项目.

private static APIInterface apiInterface;
private static RestClient restClient;
private static HttpLoggingInterceptor interceptor;

OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.setConnectTimeout(30, TimeUnit.SECONDS);
    okHttpClient.setReadTimeout(30, TimeUnit.SECONDS);
    okHttpClient.interceptors().add(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Request original = chain.request();

            Request.Builder requestBuilder = original.newBuilder()
                    .header("Accept", "application/json")
                    .header("X-Parse-Application-Id", Constants.PARSE_APP_ID)
                    .header("X-Parse-REST-API-Key", Constants.PARSE_REST_API)
                    .method(original.method(), original.body());

            Request request = requestBuilder.build();
            return chain.proceed(request);
        }
    });

    interceptor = new HttpLoggingInterceptor(); // got crash here
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

    okHttpClient.interceptors().add(interceptor);

这是我的踪迹:

java.lang.VerifyError: com/squareup/okhttp/logging/HttpLoggingInterceptor
   at com.rocker.rest.RestClient.setupRestClient(RestClient.java:62)
   at com.rocker.rest.RestClient.<clinit>(RestClient.java:39)
   at com.rocker.fragment.HistoryFragment.onCreateView(HistoryFragment.java:38)

我没有使用平方的okio!

首先,我通过Repository类管理realm实例:

public class RealmRepository {

private Lock lock;

protected RealmRepository() {
    lock = new ReentrantLock();
}

public  <T> T execute(Executor<T> executor) {
    Realm realm = null;
    try {
        lock.lock();
        realm = Realm.getDefaultInstance();
        return executor.execute(realm);
    } finally {
        if (realm != null && !realm.isClosed()) {
            realm.close();
        }
        lock.unlock();
    }
}

public interface Executor<T> {
    T execute(Realm realm);
}
}

而且这个RealmRepository扩展的唯一类就是我的控制器类.问题是当我第一次执行我的片段中的执行方法时,我得到了:

java.lang.IllegalStateException:此Realm实例已被关闭,使其无法使用.

但是在这个错误之后如果重载片段一切正常.在此第一个片段之前,执行方法从Services类调用并且运行良好.例如:即使首先执行它,此方法也能完美运行:

public Observable<ModuleRealm> getModule(String moduleTitle) {
    return execute(realm -> realm.where(ModuleRealm.class)
            .equalTo("code", moduleTitle)
            .findAllAsync()
            .asObservable()
            .first()
            .map(RealmResults::first));
}

但是这个抛出异常:

public Observable<List<ProductCategoryRealm>> …

我试图用测试来覆盖演示者。演示者用例作为数据源。用例的 Execute 方法具有以下结构：fun execute(params: TInput? = null, onNext: (TOutput) -> Unit, onError: (Throwable) -> Unit).

我的问题是如何从 onNext 和 onError 模拟发射？

这是我的 PresenterTest：

class AssignmentsPresenterTest : UnitTest() {

    @Mock lateinit var dataRepository: IDataRepository
    @Mock lateinit var viewState: AssignmentsView

    lateinit var execute: ExecuteUseCase
    lateinit var presenter: AssignmentsPresenter


    @Before fun setUp() {
        execute = ExecuteUseCase(dataRepository)
        presenter = AssignmentsPresenter()
        presenter.attachView(viewState)
    }

    @Test fun `should return list of assignments`() {
        given {
            execute.execute(anyVararg(), { }, { })
        }.willReturn(anyVararg())
    }
}
