我正在使用Espresso 2.2编写仪器测试。
流程我想测试:
我想在点击radioButton后注册IdleResource,等待vSetupAmount变为可见。但我无法使其发挥作用。请告诉我我做错了什么。
我写过这样的IdleResource:
public class AmountViewIdlingResource implements IdlingResource {
private CountriesAndRatesActivity activity;
private ResourceCallback callback;
private SetupAmountView amountView;
public AmountViewIdlingResource(CountriesAndRatesActivity activity) {
this.activity = activity;
amountView = (SetupAmountView) this.activity.findViewById(R.id.vSetupAmount);
}
@Override public String getName() {
return "Amount View idling resource";
}
@Override public boolean isIdleNow() {
callback.onTransitionToIdle();
return amountView.getVisibility() == View.VISIBLE;
}
@Override public void registerIdleTransitionCallback(ResourceCallback resourceCallback) {
this.callback = resourceCallback;
}
}
所以我将活动传递给IdleResource,链接视图和变量。我知道IdleResource不会让测试通过,直到isIdleNow()返回值true。因此,如果视图是View.GONE,那么它就不会再进一步了。
它在测试中的表现如何:
// click of radioButton picked from radioGroup
onView(withId(rgDeliveries.getChildAt(id).getId())).perform(scrollTo(), click());
// wait for view to become visible
Espresso.registerIdlingResources(new AmountViewIdlingResource(getActivity()));
// go to button on view
onView(withId(R.id.btnGetStarted)).perform(scrollTo());
// unregister idle resource
for ( IdlingResource resource : getIdlingResources()) {
Espresso.unregisterIdlingResources(resource);
}
所以我点击了radioButton。 IdleResource已成功注册,但没有任何反应。在我的设备API响应来了。正在显示vSetupAmount但
amountView.getVisibility() == View.VISIBLE;
永远被检查(但我在屏幕上看到我的视图)总是返回false。
我做错了什么?
答案 0 :(得分:16)
我知道这可能为时已晚,但我的回答可能对某人有帮助。
AmountViewIdlingResource
时,请保留对其的引用并仅取消注册该引用,不要取消注册所有IdlingResources
。isIdleNow()
方法的实现只应调用回调的onTransitionToIdle()
方法,如果您的空闲资源实际上并非每次都空闲。我需要做类似的事情,等待按钮出现在屏幕上,而这反过来只有在HTTP调用完成后才能看到。我对视图可见性空闲资源的实现如下:
public class ViewVisibilityIdlingResource implements IdlingResource {
private final View mView;
private final int mExpectedVisibility;
private boolean mIdle;
private ResourceCallback mResourceCallback;
public ViewVisibilityIdlingResource(final View view, final int expectedVisibility) {
this.mView = view;
this.mExpectedVisibility = expectedVisibility;
this.mIdle = false;
this.mResourceCallback = null;
}
@Override
public final String getName() {
return ViewVisibilityIdlingResource.class.getSimpleName();
}
@Override
public final boolean isIdleNow() {
mIdle = mIdle || mView.getVisibility() == mExpectedVisibility;
if (mIdle) {
if (mResourceCallback != null) {
mResourceCallback.onTransitionToIdle();
}
}
return mIdle;
}
@Override
public void registerIdleTransitionCallback(ResourceCallback resourceCallback) {
mResourceCallback = resourceCallback;
}
}
希望这有帮助
