What’s The 6-Step List For A Mobile App’s Quality Testing?

15th November 2021


A mobile app needs to be tested rigorously and multiple times before it’s launched. Even when any edits or changes are made, thorough testing at every stage ensures smoother operations and usability of the app. However, bug testing isn’t the only form of testing and there are many other forms of testing that one has to keep in mind when working on an app. There are mainly 6 types of testing that need to be conducted as depicted in the image above.

Performance Testing

Performance testing is done to ensure that the app works smoothly across a bunch of situations. For example, specific testing is done to check if the app can take and work smoothly through heavy workloads. What’s the highest capacity of the application for a non-glitchy experience. Another important factor often checked is the impact that an application can have on the system’s hardware- the kind of RAM capacity required, the ROM memory needed. This checks the factors like heating or battery drainage issues in the mobile app. Some tests that can help you verify these factors include:

  • Load test: Check response time to various requests like page loading, response time to navigation, etc
  • Stress test: How does the app perform when the load increases
  • Stability test: How consistently does the app perform under average load usage
  • Concurrency test: Checks how well the app does when many users simultaneously use it and/or the same functions on it
  • Functionality Testing

Functionality Testing

There are many use case scenarios where we have to test how the app functions and if those functions are feasible given the scenario. Testing for these use cases may include:

  • Testing how the installation process works
  • How does the app react to external interruptions like receiving calls
  • How will app updates affect its functionality across devices

Usability Testing

This testing is to largely check how well the UI/UX of the app is optimized. There are many ways by which you can avoid common UI/UX mistakes and learn why UI/UX optimization is super important. The design needs to be intuitive ie easy to understand for the user and simple enough to recall and replicate in terms of user behavior. This testing would ensure that the user base has a seamless experience. Parameters to be tested can include:

  • Layout optimization
  • Size & look of buttons
  • Apt icon usage
  • Logic of navigation
  • Text clarity & hierarchy

Security Testing

Security of data is of the utmost priority and risking the same can lead to serious consequences. Thus, this is a sphere that needs constant testing especially when user data is at stake. There are many things to test when checking for security & these include:

  • Confidentiality: Use of appropriate encryption tech for data security
  • Authorization: Application should request access to only the necessary services on the user’s device like storage access, camera access, etc
  • Authentication: Stringent user authentication process before data access is granted
  • Web Services: The application should only interact with secure third party web services
  • Storage: The locally stored data on the device should also be encryption protected

Compatibility Testing

When creating an app, the intended user and their devices should be kept in mind. For example, mobile phone users span across both iPhone & Android and even amongst those some users have full-screen devices and devices with older smaller screens. The app you create should be compatible with all the intended users’ devices and the necessary design ideas created. Main pointers to keep in mind include:

  • Content: What fits on a full-screen phone or a tab will not fit or be as visible on a smaller screen
  • Navigation: Simple scroll up and down function isn’t the only option, unlike a desktop site, explore other intuitive gestures like swipe, tap, shake your device, etc
  • Hierarchy: Both small & big screens should be kept in mind when layouting and creating the design hierarchy for the screens
  • Feature and Functions: Just because one feature or function works on one OS doesn’t mean that it will do the same on another, test & ensure it’s equally seamless across all

Localization Testing

This type of testing isn’t something that is usually considered as important as the ones above, however, it’s as relevant and should always be undertaken. This test is to ensure that the design, visual language, content, context or any part of your app doesn’t get lost in translation to any local communities who might be using your app. For example, the common English word ‘sale’ means to ‘come out’ in Spanish. A banner or button declaring an ongoing sale in an e-commerce app might be misinterpreted by the Spanish audience. This is a form of testing that is especially essential for global companies who cater to a much larger & diversified audience.

The user’s experience on dating apps should be easy, engaging & seamless always. Simple to navigate for a satisfying user experience. Testing helps avoid any glitches that a user might experience otherwise. It’s best to work with an end-to-end expert for mobile app development to ensure quality.
