我正在尝试编写一个测试来验证使用espresso启动意图，问题是目标（）没有记录任何意图。
我有这个测试
@Test
public void shoulddosomething(){
startActivity();
intended(hasComponent(hasClassName(TemplatePictureCaptureActivity.class.getName())));
}
在我的活动中，我有这个代码
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(onRequestLayout());
Intent intent = new Intent(this, TemplatePictureCaptureActivity.class);
startActivity(intent);
}
测试结果是这样的。
android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: Wanted to match 1 intents. Actually matched 0 intents.
IntentMatcher: has component: has component with: class name: is "cat.helm.recertel.ui.templatepicturecapture.TemplatePictureCaptureActivity" package name: an instance of java.lang.String short class name: an instance of java.lang.String
Matched intents:[]
Recorded intents:[]
我试图在onClickListen中启动intent并且它有效，但没有它我无法让它工作。我也试着闲置资源而没有运气。你知道怎么做到这一点吗？
解决方案是注册一个空闲资源以等待第二个活动。
在我的情况下，测试将保持如下：
@Test
public void shoulddosomething() {
startActivity();
String templatePictureActivityClassName = TemplatePictureCaptureActivity.class.getName();
Espresso.registerIdlingResources(new WaitActivityIsResumedIdlingResource(templatePictureActivityClassName));
intended(hasComponent(hasClassName(templatePictureActivityClassName)));
}
而这里是闲置的资源。
private static class WaitActivityIsResumedIdlingResource implements IdlingResource {
private final ActivityLifecycleMonitor instance;
private final String activityToWaitClassName;
private volatile ResourceCallback resourceCallback;
boolean resumed = false;
public WaitActivityIsResumedIdlingResource(String activityToWaitClassName) {
instance = ActivityLifecycleMonitorRegistry.getInstance();
this.activityToWaitClassName = activityToWaitClassName;
}
@Override
public String getName() {
return this.getClass().getName();
}
@Override
public boolean isIdleNow() {
resumed = isActivityLaunched();
if(resumed && resourceCallback != null) {
resourceCallback.onTransitionToIdle();
}
return resumed;
}
private boolean isActivityLaunched() {
Collection<Activity> activitiesInStage = instance.getActivitiesInStage(Stage.RESUMED);
for (Activity activity : activitiesInStage) {
if(activity.getClass().getName().equals(activityToWaitClassName)){
return true;
}
}
return false;
}
@Override
public void registerIdleTransitionCallback(ResourceCallback resourceCallback) {
this.resourceCallback = resourceCallback;
}
}
试着等一会儿
intended(hasComponent(hasClassName(TemplatePictureCaptureActivity.class.getName())));
