Hi, for today I have some tips about swiping ViewActions in Espresso for Android. As you may know the latest Espresso release contains new swipeLeft and swipeRight ViewActions. They both are really useful when you'd like to swipe between activity fragments, tab layouts or any other UI elements. You can use it as any other view action: onView(withId(R.id.viewId)).perform(swipeRight()); But be aware that doing this you will operate on a view, in our case R.id.viewId, but not on the screen size. That means that to swipe right or left, for example between fragments you have to deal with some parent layout or maybe list view. If you take a look inside Espresso's ViewActions.java class you will see below code for swipeRight() method:   public static ViewAction swipeRight() {     return new GeneralSwipeAction(Swipe.FAST, GeneralLocation.CENTER_LEFT,         GeneralLocation.CENTER_RIGHT, Press.FINGER);   } As you may g...

After more than a month of using great test tool from Google - Espresso for Android, I'd like to share with you some of my experience. I assume that you've already added espresso jar into your project, spent some time playing with Espresso samples and have basic understanding how this tool works. In this post I'll show how to match particular view with text or assert that it contains (or not) specified Strings. Before we start, you have to take a look at Hamcrest matchers - Hamcrest tutorial and API Reference Documentation , which are used together with Espresso's ViewAssertions and ViewMatchers and included into Espresso standalone library. Pay more attention to Matcher<java.lang.String> matchers. So, here we go. For simplicity following String "XXYYZZ" will be used as a expected text pattern. Espresso ViewMatchers class implements two String matcher methods withText() and withContentDescription() which will match a view which text is equal...
