Mobile app development is evolving at a very fast pace. There’s an app for almost everything, from dating and tracking sleep cycles to making doctor’s appointments and booking flights. Shopping, music, finance, fitness classes, news, and reading — digital users can get all this done through apps.
Comprehensive mobile apps testing helps prevent user churn because as much as 80% of users uninstall apps that don’t meet their expectations. Mobile testing teams need practical tools to execute smart and efficient test cases that contribute to developing reliable and user-friendly apps.
There is a vast number of free and paid tools in the market, each with different strengths and weaknesses. Hence, selecting a mobile app testing tool can be confusing, especially for those who don’t have enough experience in the field. This article provides descriptions of the most popular paid and open-source mobile testing tools to assist you in choosing the one that can speed up and scale your testing efforts. To be more precise, we’ll cover:
Choosing Mobile Testing Tool: Essential Questions to Answer
With so many variants out there, finding the right mobile testing tool can be difficult, but it is crucial for successful test execution. Without thorough research, many end up wasting time and resources trying to force a square peg into a round hole. Let’s discuss what questions need to be asked to ensure you select a mobile testing tool that will best meet the needs of your project.
- Does the tool offer integrations with commonly used app testing tools and frameworks? When making your final decision on buying a mobile app testing tool, you expect the tool itself to include all necessary resources — no additional downloading and installing are needed.
- How often is the mobile testing tool updated? Has it ever fallen victim to a security breach? Data protection of the tool is a must, especially in the face of widely spread cyber attacks, viruses, and malware.
- Can the tool create a comprehensive test summary report, explaining the overall testing activities performed? This includes details on what was tested, when it was tested, how it was tested, and the environments in which it was tested.
- Does your team of technical experts possess the necessary knowledge and skills to execute tests with this tool? If not, can they get a hold of the tool quickly?
- Does the tool provide scriptless methods? The ability to create tests without in-depth knowledge of the code is of great help. Scriptless testing tools simplify the human effort required to conduct a test.
- Can it integrate with CI/CD pipelines and external platforms? This ensures continuous testing, security, and high quality.
- Can you request a trial version of the tool free of charge to try all the features it has to offer and experience exactly what it can do for you before making the actual purchase? This is the best way to get a feel for the mobile testing solution and how it operates.
