The innovation of the iPhone has had a significant impact on the smartphone and the wider tech industry at large. Today, iOS apps have a significant market share, with over 1.5 billion people using iPhones, which equates to 30% of the market share. The number and market share of iPhone users continues to grow with the invention of iOS devices with advanced features.

This trend has made iPhone users go for Apple products due to the many benefits they get. Apart from robust security, apple products are known to be effective and reliable in many different ways. Therefore, every iOS developer should put in measures to ensure they release top-quality, reliable, ad fully-functional iOS apps to meet user anticipation.

iOS app testing is a viable way to ensure all the features, security, user interface, and functionalities of iOS apps, among others, meet industry standards. But then, what should iOS developers check before launching the app to the market? Let’s learn more in this iOS application testing checklist guide.

What is iOS testing?

iOS app testing is the process of verifying the usefulness and effectiveness of iOS apps on Apple devices to verify their usefulness and to measure performance metrics. Among the elements to check include overall performance, load time, app store listing, user experience, and user interface. The essence of iOS testing is to enhance the following:

  • Fixed functionality – All Apple devices and operating systems maintain a uniform functionality to overcome certain functionality risks. A good example if the force-stop function in the Android apps, which is not applicable in iOS apps.
  • Device consistency – Apple has a limited range of device models and sizes to simplify the QA testing. When the team knows the available devices in the market, it becomes easy to establish the app testing tools and processes.
  • Strict submission guidelines – Apple has a strict guideline to follow for all the processes. This enhances the app’s success once it is launched.
  • Operating system clarity – The iOS system embraces the closed nature contrary to Android’s nature of divers OS versions. This enables iOS developers and teams to evaluate and decide on the best test set for the iOS operating system within the shortest time and effortlessly.
  • Simplified GPS testing – it is easy and seamless to test GPS functionality in iOS devices since to has in-built features to execute GPS processes like cycling, running, or walking. This approach eliminates the need for field tests and only focuses on the process using dummy GPS data.
  • Automation tools – Apple has a set of test automation tools to simplify the testing processes. However, developers might need some time to learn and master these tools.

Why is iOS app testing important?

There are many reasons why testing the iOS app is a crucial step. Among the top reasons or purposes for testing iOS apps include the following:

  • Promoting user retention and growth

No user wants an app that performs poorly with a lot of errors and crashes. In fact, many users uninstall an app immediately after they experience errors and crashes after downloading it. Similarly, many users also remove the app after a specific timeline after realizing how unstable and reliable the app is. All these challenges and problems are a result of poorly developed apps with no testing done.

No business wants to encounter such costly processes of developing and launching an app only to be rejected by users. That is why iOS app testing helps solve all the issues before the release of the product. This helps attract a large user base while maintaining a high retention rate.

  • Preventing bugs in the final production phases

It can be costly to fix bugs after the iOS app is already deployed in the market. That is why performing iOS app tests is a key aspect, as it helps the teams detect and fix bugs during the early stages of iOS app development. This, in turn, enhances the viability of the app, making it perform well and cutting down on maintenance costs after the launch of the app.

  • Enhances brand reputation

A well-performing and fully functional iOS app creates a positive brand reputation. However, if the app has a lot of issues with downloading, installing, and using, it is likely to ruin the reputation of a company. As an iOS developer, you can avoid a bad reputation by executing iOS app testing processes.

  • Development Cost reduction

Developing an iOS application can be an exhausting and expensive process. In fact, detecting and fixing bugs in the later app development stages can be costly. That is why it is important to perform iOS app testing before you launch the product to reduce overall development costs.

  • Competitive advantage

The iOS app development market is highly competitive. Therefore, many users are looking for a stable, high-performance, and reliable iOS app. Of course, a poorly designed and developed app will face stiff competition and might not survive in the market.

iOS app testing helps developers improve all aspects of the app, enabling it to penetrate the market easily and overcome the stiff competition.

  • Better return on investment

As mentioned before, a better-performing app will attract a large user base and enhance a higher retention rate. When more users are downloading, installing, and using the app throughout, it puts the business ahead, thus maximizing profits from all angles.

Process of iOS app testing

Before you execute the testing process, you need to follow the steps below to ensure the whole process is successful:

  • Have a complete test plan

Start by drawing a practical test plan by defining the scope of testing, the processes, test types, reliable platform, and any other element contributing to the test process. Don’t forget to highlight the tools and other requirements necessary for actualizing the process.

  • Create test scenarios and cases

With a reliable plan, you can now formulate test scenarios and cases. Here, focus more on defining the extent of automation testing because not every process requires automation tools. The teams should note specific areas where automation is applicable and prepare the necessary processes.

  • Choose the ideal mobile device for testing

Finally, you need to select a reliable mobile device to use for testing. Using emulators and simulators is the best approach here, considering that buying devices for every test requirement can be costly.

Types and approaches of iOS app testing

There are different types of iOS apps. That is why, when performing iOS app testing, you should understand the nature of the iOS app you are dealing with. We have three approaches, which include the following:

  • Web applications – These are iOS apps accessed through websites using a safari browser for iPhone. Ideally, these apps function just like built-in iOS apps.
  • Native iOS apps – These are apps developed with SDK – iOS software development kit and they run on native iOS devices. Uber, Flipboard, and VLC are examples of iOS native apps.
  • Hybrid applications – Hybrid apps are a blend of native and web app components. The hybrid iOS apps give users access to web content via native iOS UI and viewing area. Gmail, Twitter, and Zomato are typical examples of hybrid iOS applications.
