In this article, you can find the information about special tools that could make your mobile applications testing easier and more effective. Nowadays there is a trend of mobile applications rapid growth. There are millions of apps designed for different kinds of platforms that need to be tested. OS platforms variety is not the only challenge tester has to face to. The others are:
- different mobile app types
- multitude mobile devices
- device fragmentation
- test interfaces variety.
The most popular tools, as well as special needs tools, will be considered below
So, let’s start.
The most often used and multipurpose Tools
Appium supposed to be the most well-known tool for mobile applications testing. The special Appium philosophy principles describe this app in the best way:
- The user shouldn’t have to recompile your app or modify it in any way in order to automate it.
- The user shouldn’t be locked into a specific language or framework to write and run your tests.
- A mobile automation framework shouldn’t reinvent the wheel when it comes to automation APIs.
- A mobile automation framework should be open source, in spirit and practice as well as in name!
Using these 4 principles gives the main merits for Appium.
- Appium is a freely distributed open source mobile application testing framework.
- Appium has a framework or wrapper that translate Selenium Webdriver commands into UIAutomation (iOS) or UIAutomator (Android) commands depending on the device type, not any OS type. So, there is no dependency on Mobile device OS.
- Appium supports automation of hybrid, native and mobile web applications on physical devices as well as on an emulator or simulator both.
- Appium supports multiple platforms: iOS, Android, Windows, FirefoxOS
Of course, Appium is the non-ideal tool. So it has some disadvantages too:
- Appium directly supports Android version 17 and later. The elder versions are not supported.
- There is no direct Android alert handling support.
- There is no ability for direct image location. The user had to work with screen coordinates to do it.
- Over 50 open bugs with iOS
Selendroid is one of the most powerful test automation frameworks for the multi-type of mobile applications: native and hybrid Android apps and mobile web. Here are its main features:
- As Selendroid tests are written on the Selenium Web driver client API, so it supports full integration with current Selenium frameworks.
- It can be used on emulators as well on real devices simultaneously. So you have a great tool for the compatibility testing.
- Existing emulators are started automatically.
- Special test case development tool – Inspector for checking the current state of your app’s UI.
- No modification of app under test required in order to automate it.
- Selendroid supports old versions of Android starting from the 10-th.
- The user has an ability to change the hardware devices (plug and unplug) during the testing without restarting or stopping the test.
- Full integration as a node into Selenium Grid for scaling and parallel testing
- Full compatibility with the JSON Wire Protocol/Selenium 3 Ready.
- Click actions recording.
Some disadvantages of Selendroid:
- Selendroid directly supports only Android. Though, it’s fair to mention, that you can use ios-driver for testing any iOS native, hybrid, or mobile web application.
- The user has no ability to automate activities outside of app like camera, maps etc.
- Selendroid is quite slow. It is hard to be used on some machines with less than 4GB RAM.
