Top 10 Tools for Mobile Testing
 |
In early 2023, approximately 5.44 billion individuals were using mobile phones, representing 68 percent of the global population. No wonder, these days, businesses have started investing in building mobile apps for their systems to entice more customers. Rightly so, mobile devices have become an integral part of our day-to-day lives. One can do anything on their mobile device, from ordering food and paying bills to booking travel tickets. With all the focus on mobile apps, you can imagine the expected quality of these applications, with an emphasis on finding novel ways to satisfy customers, develop those features, and test them.
When it comes to testing these rapidly evolving applications over such versatile platforms, having an automation framework in place is helpful. Let’s take a quick look at the process of testing mobile apps and some popular tools that help you achieve this.
Types of tests to automate
Similar to automation testing on any other application, the test suite can be flaky and burdensome to manage if not planned carefully. Hence, you need to pick out the right scenarios for automation. You can start by testing at the three primary levels –
Unit Testing – These tests are meant to look at the smallest code units and ensure they work. This is a fast way to test parts of your application.
Integration Testing – When multiple modules are interacting with one another, testing this interaction is essential as these areas are more prone to errors.
End-to-end testing – Performing these UI-based tests is a great way to validate user journeys. Since mobile applications can be fragmented across OSs and devices, having these test cases in place will help.
More scenarios to look at while testing
While testing at the above three levels gives us a fair idea of the quality of our application, let’s also consider the nuances that might arise, particularly with mobile applications.
Operating system – Mobile applications can be native or hybrid. With the variety of devices and OS versions in the market, it becomes tricky to be sure whether your application will work on all of these platforms or not. Hence, you have different simulators and emulators that help mimic all these cross-browser and cross-platform combinations for testing.
Device size or form layout – Here, we are talking about the screen size, whether it is a small 3.5-inch mobile screen or a tablet of 8.5 inches or larger. How your application is rendered on these different devices is crucial for determining the success of your application.
Location-based scenarios – If your application requires GPS, then testing those scenarios is essential, too. Consider an example where your application is supposed to provide services for booking cabs. Here, you will need to ensure that scenarios like location detection based on ‘current location’ are working and that real-time location is used to determine the arrival time.
Situations affected by connectivity – The essence of mobile phones is to allow you to work on the go. It is thus quite possible that you may face issues where your network bandwidth fluctuates, or you are in airplane mode or offline. In such situations, how your application should behave is another crucial factor to consider.
Some tips to ensure good quality mobile testing
Based on your needs, you can pick from various mobile testing tools. However, you can consider some of these points when going through them.
Consider the form layout of the devices you intend to support
If your application is not responsive on tablets but is supposed to be, then pick a tool that helps you handle this test scenario.
Test on both real and virtual devices
When it comes to testing mobile applications, emulators and simulators make it easy to check all the different platform permutations. However, if you only go with these virtual devices, there’s a chance that you might miss out on situations that the end user will face when using the application on an actual device.
Testing infrastructure
Is your tool using the cloud or on-premise resources for testing? It is convenient to have a cloud-based testing platform as it comes with more features and flexibility.
Integration with other frameworks
Choosing a testing tool that integrates with other frameworks and tools will be beneficial. For example, if you want to build a testing ecosystem, your automation testing tool should work smoothly with your CI/CD and issue management frameworks like Jira.
Mode of creating test cases
Based on your team’s skillset, you can choose a testing tool that requires no coding, low coding, or entirely depends on coding. Most modern automation tools offer no-code capabilities to ensure that your team can leverage the benefits of automation testing without getting entangled in the complex technicalities of the tool, like learning a programming language.
