Mobile App Testing Tools

Are you looking for the best mobile app testing tools in 2021 and beyond? In this article, we have hand-picked the best mobile application testing tools to test your mobile applications. 

The software development industry seems to have grown in a fanatic pace like never before. For once, I think we can count stars in the sky but it can get insanely tricky when it comes to counting Android and iOS apps here!

Like it or not, the world has an insatiable appetite for new and better ones. One single mistake can be a major turn-off. I firmly agree with the fact that we are the victims of such mobile apps’ blunders, irrespective of which corner the issue sprouts up. And in that case, it becomes necessary to test a mobile app.

Smartphone apps are developing more than babies born every day. Due to which both Android and iOS app developers require to stay aware of the pace. In the entire mobile app development process, the most tedious or complicated task turns out to be app testing. Surviving in today’s competitive environment requires the product to be centered around a particular functionality and needed to give a superior user experience like never before. One wrong move could lead to an immense loss.

How to excel in the field of Mobile Application Testing?

I highly recommend you go through our Mobile App Testing Guide to learn more about Mobile Testing.

Like I said before, nobody wants to be treated as a Guinea pig. If they find a flaw, you would not hear about the error from them and they would most definitely not come back. Henceforth, enterprises, executive managers are considering high-performing solutions that can deliver results – Mobile Testing Tools!

Further down through the post I would like to get you acquainted with all the foundational information and knowledge of tools required to get you started with test-automation for your mobile apps. However, you will come across a plethora of resources and tools out there; which can certainly be overwhelming at times. So, let me break it down for you! But before that, one must know!

Challenges Faced In the Mobile Testing Field

  • A wide range of mobile devices including smartphones, tablets of various sizes and densities which are iOS and Android-based ready to be explored.
  • Another challenge here is dealing with a variety of hardware configurations featuring memory optimizations, CPU optimizations, and OS optimizations.
  • Dealing with multiple OS and their versions.
  • Mobile app development methods right from native app to creating responsive web apps, hybrid apps, and what not!
  • The necessity of frequent app updates.

Why invest in Mobile Application Testing Tools?

Manual testing slows down the app release cycle- Enterprises should ask mobile app developers to release features faster so that you want to reduce the manual effort required to run the regression tests, and allow the testers to focus on testing new features.

Errors reported after the release deployment- Unlike manual testing, mobile app testing tools support continuous delivery efforts so that each commit can be deployed safely and frequently. The faster the feedback, the less expensive it is to fix an issue that is found.

QA teams can be innovative- By combining Quality Assurance teams with mobile testing tools, you can easily increase testing speed and coverage like never before.

Which parts of the mobile app should you automate first?

One must strategize on which areas would benefit from automation and what kind of specific components should be tested at first. If done right, everything works wonders like a mobile app being less exploratory and hacky.

The scope of the test has to be automated and decided on the most urgent testing priorities. This surely includes any core component which has been tested even manually. Consider the frequency of testing, business priority, and what parts are capable of being automated.

So further look at the functional test-cases which:

  • Are time-consuming?
  • Can be simplified and structured into logical steps
  • Are critical core-flows in terms of the app’s functionality?
  • Have been known to cause issues in the past
  • Require a large amount of data for testing
