Android Automation Testing Frameworks: See The Best of Them
When we use an attractive and thoroughly developed Android app, we usually don't ponder on how it has been created. But before the app is released, it evolves from the original idea to the elaborated project. And the testing is one of the most crucial stages of the app development. Due to the QA testing, the app can be verified for presence or absence of any bugs. Moreover, QA engineers can also check the performance level and thought-out UX of the app.
So how are Android apps tested? They are tested using special frameworks and other tools that can help perform the testing at the highest level and fix all bugs before it is released. That is why testing service means a lot for any software development company, and we are not the exception to this rule. What frameworks do we use for Android app testing? You are here to figure it out.
Android UI frameworks for automated testing
First, we would like to speak about UI frameworks for automated testing. User interface testing makes it possible for QA engineers to see whether the app meets the UI standards, how it was implemented etc. Mobile app automation testing is considered to be one of the most accurate testing types.
Robotium is a framework for testing Android apps that allows QA engineers create test scenarios for functional, systematic and behavior testing. In fact, this framework gives the opportunity to perform gray box testing.
It is a reliable and well-known tool. The framework is constantly being updated, and its performance is improved after each update.
Robotium Android testing is provided in the form of a JAR file to be compiled with your project.
Know everything about testing types.
- You need minimum time to write solid test cases;
- You can create good test cases with the minimal knowledge of the app tested;
- Framework can process a few testing processes for Android automatically;
- Automated synchronization;
- Quick testing implementation;
- Tests are more reliable due to runtime binding to UI components.
- It doesn't offer screenshots feature;
This framework for Android application testing is created for developers that consider automated testing as the component of system development lifecycle. For those who are skilled in coding a bit, testing will take less time. The tool has a programming interface that is simple-to-understand and it can be changed if necessary since the framework is open-source.
It is designed for white-box testing. Despite the fact you need to be familiar with the app tested and understand the code, Android Espresso tests are running fast and they are reliable. But it can test only one app at a time.
- Espresso API tests are displayed as a common English text, so you can learn to work with it very fast;
- It has a small API;
- It is launching fast;
- Gradle+Android Studio support.
- It doesn't support webviews.
Strong sides of Espresso and Robotium frameworks
UIAutomator is developed by Google corporation and supplied together with Android SDK. This framework is an analog of UIAutomation tool of Apple company but for Android test. Android SDK provides QA engineers with the following tools for automated functional testing of user interface:
- UIAutomatorviewer is a graphic tool for the recognition of UI components in Android app;
- UIAutomator is set of Java API libraries that contain methods for the creation of user interfaces tests.
To use these tools, specialists need to to have Android SDK Tools ver. 21 or higher, and Android SDK platform API 16 or higher.
It is a black-box testing tool. UIAutomator is created only for native Android apps that is for Android auto test of apps.
- You don't depend on screen resolution;
- All actions are bound to Android UI components. It allows specialists to work directly with UI elements;
- You can start complicated sequence of actions;
- You can use external buttons on the device.
- It works on Android devices with API 16 level or higher only;
- It doesn't support webview as well.
