First released on June 29, 2007, iOS is the Apple’s foundation for portable smartphone and mobile applications. In contrast to Android, Apple doesn’t permit iOS to install on non-Apple devices and hardware, iOS & iOS applications can just be installed on Apple mobile devices.

Your application must go with the following four types of iOS devices:

  1. iPhone
  2. iPad
  3. iPad Mini
  4. iPod

Types of iOS Devices

These are the basic questions that a developer asks himself while developing an iOS application:

  • How my iOS app can be bug free?
  • How will I do the app testing?

It doesn’t make a difference how much time you had put into designing the application, failures are inescapable, and bugs will show up at the end. There are a few common errors in iOS apps the cause problems like:

  • App Incompatibilities
  • Application Crashing
  • Memory Leak
  • Security Bugs

If you are here in search of a testing company for your iOS application BugEspy can be the right iOS app testing partner, visit our Software Testing Page here.

Now let’s talk about our topic, how to test an iOS application. Following are the types of testing that play a vital role in making your iOS app bug free and efficient. 

Automated Testing:

Automated testing has many points of interest in iOS app testing. It allows you to recognize the bug and issues in performance rapidly. The advantages of automated testing are:

  • Automated testing could be run on various gadgets, sparing your time.
  • Automated testing would target SDKs. You could run tests on various SDK variants.
  • Automated testing increments your efficiency of testing and save the expense of software development and programming.
  • There are a lot of open-source testing systems that support the process of automated testing on iOS.

Unit testing with OCUnit:

At the point when the first iOS SDK was launched, it needed Unit Testing abilities. Hence, Apple brought the solution of the OCUnit unit test in SDK version 2.2. In Mac OS OCUnit is an app testing structure for C-Objective.

The greatest advantages and focal points of an OCUnit system are the strong integration into the XCode development environment as demonstrated below.

Benefits of OCUnit:

  • Object-oriented tests
  • Low overhead
  • Same languages as implementation
  • Integration to IDE
  • Records testing capabilities
  • Easy installation
  • Open source license

UI Automation Testing:

Provided by Apple, UI Automation is basically aJavaScript library, used for the execution of automated testing on real gadgets and iOS simulator.

UI Automation provides you with the following advantages:

  • No need to put big efforts into Manual Testing
  • Use less memory to execute all of your testing processes.
  • Rearrange your UI testing method and make it simple (run your test by pressing press 1 or 3 buttons)
  • UI Automation instrument operates from the script that is written in JavaScript. It recreates and simulates events of a user on the target iOS app.
  • It is a process of low-cost testing but it could leave some potential errors and bugs in your iOS app.
  • Detect the serious errors sooner and less preparation is required to detect the bugs speedily without the need of any plan.
  • By means of exploratory testing many bugs and errors are discovered initially.


  • Require testers with high skills.
  • It does not make sure that all the needs and requirements are sufficiently tested.
  • Lack of test documentation.

User Testing:

User testing is a type of manual testing on IOS applications used to create some better apps without any errors, we’ve shown four types of user testing below.

Concept Testing:

Concept testing analyzes the response of users to an app before it is launched to the marketplace. Concept testing procedures on iOS apps are stated as:

Usability Testing:

This type of testing examines that how easily a user can use that iOS application. In the process of iOS manual testing, the usability testing can play a vital role in effecting the success of the app.

We have mentioned two tools for iOS usability testing here:

  • Magitest, is a common usability testing tool for iOS apps and sites.
  • Delight.io, capture the detection of real-time results to your application.

Beta Testing:

Beta testing is performed to get the final feedback from application users by means of integration of testing results with real-time data. You must follow these steps below to distribute your application for beta testing.

  • Before distributing your app to the testers be sure to first run some basic tests of the app, like the ones mentioned above.

A/B Testing:

A/B Testing Example

You can evaluate the effectiveness of your iOS application with the use of the A/B testing process. It utilizes random equipment with 2 devices, A & B. Three main steps involve in A/B testing as below:

1) Test configuration:

Prepare two versions (A and B) for your iOS application and test metric.

2) Test:

Test the IOS application versions simultaneously on both devices.

3) Analyze:

Select the better performing version before release.

The right tool that supports the process of A/B testing.

Arise: This tool is used to test both Android and iOS applications. It could be integrated into an iOS application and perform the testing process more efficiently.

The Best Practice:

  • Defined your test target. All the testing is useless without having a target.
  • Watch the end users using your application for the first time.
  • Per update runs a single test only. During the process of testing it will save your time.
  • Carefully monitor test. By monitoring it you could learn all the experiences from your testing.
