问题 Espresso claims that there is no need for Thread.sleep(); , but my code doesn't work unless I include it. I am connecting to an IP. While connecting, a progress dialog is shown. I need a sleep to wait for the dialog to dismiss. This is my test snippet where I use it: IP.enterIP(); // fills out an IP dialog (this is done with espresso) //progress dialog is now shown Thread.sleep(1500); onView(withId(R.id.button).perform(click()); I have tried this code with and without the Thread.sleep(); but

问题 I am using val activityRule = ActivityTestRule(SingleFragmentActivity::class.java, true, true) and SingleFragmentActivity is a test helper activity class I used from google GithubBrowseSample how can I launch activity with bundle ? 回答1: You can get activity from activityRule and you can set extra data for intent activityRule.activity.intent.putExtra("key",value) 回答2: There are 2 ways of achieve what you would like to. First one, unfortunately, require creating custom ActivityRule , which will

问题 I have been wrestling with a legacy Android app, attempting to add testing and proper architecture to it. The app has a main LaunchActivity which runs a series of checks on launch. Originally, the activity was using Dagger to, rather poorly, 'inject dependencies' that the activity would use to run checks. I shifted gears to MVVM, so that I could test the view model separately, without instrumentation, and would only need to inject a mocked view model for UI tests. I followed this article to

问题 I'm trying to create Espresso UI test inside the new Android project but I faced with the following problem.

问题 In my espresso test, I close the app by using "device.pressBack()". I then want to re-open the app, in a certain Activity, but I'm not quite sure how to do that, since I don't even have a context at this point. Does anybody have an idea? 回答1: OK, got it. You define a rule in your test class: @Rule public ActivityTestRule<MyActivity> myActivityTestRule = new ActivityTestRule<>(MyActivity.class, true, false); Then, after you used device.pressback(), you can use this to open that specific
