Automation Testing – Best Open Source Tools For Mobile Apps

Why Mobile App Automation Testing?

Testing of Mobile Apps in quite cumbersome because of sheer magnitude of testing required on variety of devices. Moreover, Mobile Apps require changes faster than other kind of Applications (Web or Desktop). That’s the reason, more and more organizations have started realizing the need of using automation testing over manual testing as much as possible.

Mobile App Automation Testing can be a massive undertaking, and if unaware, one can end up complicating the process by selecting a bad tool. With a major trending shift to open-source mobile test automation tools, there have been a plethora of tools available in most open-source software markets.

So how do you know which are the best software testing tool available in the market? Which tools will give you the most efficient solution to fulfill your enterprise’s need for speed and integration? Will manual testing suffice your app testing needs?

This blog post is to help you quickly choose which open-source test automation tool will be right for your automation testing

Benchmarks for selecting the right tool

You would need a set of criteria to fulfil when assessing your selection of the right open-source automation tool. Here are a crucial few questions to ask:

• Do you have the required skilled resource for automation tasks?
• Is there ease of script development to support agile processes and shorter iteration cycles?
• Does the tool support cross team collaboration for seamless use by QA and Dev?
• Can it match app platform with test development language?
• Will it have performance capabilities gaps while testing?
• Will it support both real devices and emulators?
• Does the app support multiple platforms — Mobile and Web?
• Does it have multi device execution capability
• How easily can it integrated with external Device cloud platforms?

Best Open-Source Mobile Testing Frameworks to use:

To take the final call, testers must have a strong awareness of the tool’s strong and weak aspects, what it can do and what it cannot, and find a balance between cost and benefit.

These are top highly adopted open source test automation frameworks available in the market.

• Easy to develop techniques including test recorders
• Support both types of unit testing and functional UI

Con: Both are app context only, which means limited ability to test for user condition scenarios

4. Selendroid: An open source automation framework which drives off the UI of android native, hybrid and mobile web application. A powerful testing tool that can be used on emulators and real devices. And because it still reuses the existing infrastructure for web, you can write tests using the Selenium 2 client APIs.

Pros:

• Can interact with multiple Android devices and simulators simultaneously
• Can simulate human actions like touch, swipe, drag etc. on devices
• Supports development tools using any WebDriver compatible language including Java, C#, Ruby etc.

5. Robotium: Widely adopted open source Android test Automation framework.

Pros:

• Easy to write powerful test scenarios
• Full support for native and hybrid Android Apps
• Easy to use recorder
• Handles multiple Android routines automatically

6. EarlGrey: EarlGrey is a native iOS UI automation test framework that enables you to write clear, concise tests. It integrates with Xcode’s Test Navigator so you can run tests directly from Xcode or the command line.
