The Importance of Quality Assurance in App Development


Your great app idea is your brainchild and you want the end product to be loved by your users as much as you love it. That means the UX needs to be flawless and transitions need to be spot on. In order to deliver a seamless app to the marketplace, it’s crucial to do quality assurance (QA) throughout the app development process.

It’s no secret that the app development space is thriving but it’s also very competitive. So, when you deliver your app to the marketplace it needs to be top notch to stand out. QA is a crucial piece of the puzzle to ensure a viable app.

Having the right app development team can make or break your app and having QA engineers on your team is imperative. Identifying bugs from the very beginning is pivotal when it comes to app success so let’s dive into the process and what you should look for when it comes to a QA engineer on your app development team.

Why Does My App Need QA?

In 2018, there were 194 billion app downloads. This proves that there is a lot of room in the market for your great app idea. However, 52% of users are frustrated by overall app performance. These shocking statistics tell us that while apps are in high demand, over half of the apps downloaded are a letdown. In order to ensure your app doesn’t fall into the app performance frustration category, QA is a crucial stage in app development.

QA engineers test all aspects of an app while it’s in the development phase to find and eliminate any bugs or hang ups in the app. This way, when it goes to production, the app is seamless. QA engineers work in tandem with app developers so that any bugs located can be fixed right away. This crucial step shouldn’t be skipped because nothing will cause users to uninstall an app more quickly than coming across a bug in your app.

Common Bug Occurrences

Let’s explore common bugs that occur in the app development process so that you know what to expect from your QA engineer:

User data input: One of the most common areas that bugs exist is when apps require users to put in data. These data fields must be tirelessly tested by QA to make sure that this app functionality works properly.

Popup messages: Whether popup messages aren’t grammatically correct, or they are too complex for the average user to understand, popup messages are an area of apps that a good QA team will pay close attention to.

Multiple device testing: A good QA team will test your app on multiple mobile devices. One of the most common hang ups is that an app performs differently on each mobile device and it’s easy to let bugs fall through the cracks if an app isn’t tested on multiple devices.

Dynamic Testing

With the app market being so competitive, dynamic testing needs to be performed on your app before it hits the market, so you need to make sure that your QA engineer is top notch.

A competent QA engineer will run dynamic tests on your app during the app development phase so make sure they do the following tests:

  •         User experience with the UX of your app
  •         Performance of different components of your app
  •         Functionality across different devices
  •         Enhanced security features
  •         The streamlined process of entering user data
  •         The installation process when the user downloads the app
  •         Resource usage (does it drain a phone’s battery?)
  •         Memory usage

Can’t My App Developer Perform QA Testing?

Whether it’s for budgetary reasons or a team lacks a QA engineer, many companies rely on their developers to do QA testing. While developers are very talented, it’s essential that your app gets a second pair of eyes on it from someone who specializes in QA services.

Having a QA engineer on your app development team means that your app developer can spend more time writing new code and implementing new features instead of running exhaustive tests on your app.

QA engineers have a distinct set of skills and specialize in running tests to ensure that your app is flawless.  They are extremely knowledgeable when it comes to user behavior and running a series of tests that mimic consumer behavior to identify potential bugs.

App Security

Security flaws are hard to recognize so it’s extremely important that your QA engineer is an expert when it comes to data security and compliance standards.

This is especially important when it comes to MedTech and FinTech apps. Authentication, data storage, compliance and other security issues can be thoroughly tested by your QA team. They’ll know the ins and outs when it comes to compliance and making sure information stored on your app functions properly.

Key Takeaways

The app development market is thriving but there is also a lot of competition. Users will be quick to uninstall an app that has bugs so if you’re developing an app, you need to make sure you have a QA engineer on your team. QA engineers are highly experienced professionals who will work hard to identify any bugs that your app may have and will ensure that you deliver a flawless app to the marketplace. Be sure to vet your QA engineers for the following:

  •         Experience doing dynamic and tireless testing to identify bugs in all parts of your UX
  •         Has a strong knowledge of app security regulations and potential issues
  •         They have good interpersonal skills to work hand in hand with your developer

It may be tempting to overlook QA and leave the bug testing in the hands of your developer but that could be a mistake that could make or break your app. Take our advice to heart and find an app development team with a QA engineer ASAP!
