Note: Only use this method if all your tests run on API versions Build.VERSION_CODES.JELLY_BEAN_MR2 or above. ![]() This is great, because all of the screenshots can be taken, even if, for example, the Activity/Fragment is not currently displayed on the screen or a system dialog is in the foreground.Īs I said, we’re gonna need the Screenshot.capture() method:Ĭreates a ScreenCapture that contains a Bitmap of the visible screen content for Build.VERSION_CODES.JELLY_BEAN_MR2 and above. This library contains a Screenshot class and capture() method that we’re gonna need. The solution I found is simply… using Android Support Test Library. Well, first of all, Android 4.3 is a minimum system version we need to have in our project, because we are gonna be using UI Automator under the hood. I decided that this was too much for a simple operation like taking a device screenshot, so I began to research for a better solution. One guy from my project spent a few days to manually fix some code inside the library to make it work on Windows 10. These libraries were honestly a pain in the ass, completely impossible to set up and use in a long term. ![]() I’ve worked on a few projects that used screenshot testing and these test were always dependent on external libraries like Karumi Shot or Facebook Screenshot Tests For Android.

One of many ways of using this mechanism is to test the UI and take screenshots of every screen in our app. On Android we have also Instrumentation Tests - tests that run on physical devices and emulators, and they can take advantage of the Android framework APIs and supporting APIs, such as AndroidX Test. You must write them to ensure that a particular part of the code is working. The most basic tests for any application are Unit Tests. Every good Android application should be well tested to minimize the risk of error after releasing it to the world. ![]()
