iOS App Testing is a testing process in which an iOS application is tested on real Apple devices to check whether it works as expected or not for specific user actions like installation time, user interface, user experience, appearance, behaviour, functionality, load time, performance, App Store listing, OS version support, etc.
iOS App Testing is required because iOS is Apple’s platform for mobile applications which was released on June 29, 2007. Unlike Android, Apple doesn’t license iOS for installation on non-Apple hardware. iOS and iOS applications can be only installed on Apple devices hence, your iOS App must be compatible with iOS versions and iOS devices.
This is the common question when developer create an iOS application.
It doesn't matter how much time you invest in design and implementation, mistakes are inevitable, and bugs will appear. There are some common bugs on the iOS application. As shown in below figure.
One of the most frustrating problems, when using Apple's devices, is that an application may crash frequently during execution. Many times the app crashes because there's some bugs or memory leak in apps.
Your iOS application may run perfectly on current iOS version, but if iOS is upgraded, it may not work due to incompatibility issues.
A Security vulnerability in iOS allows the hacker to attack your iOS devices, steal your private information. Until now, severe iPhone security vulnerabilities are discovered in different iOS versions.
Memory leaks are blocks of allocated memory that the program no longer uses. Memory leaks cause your iOS application to crash. They are bugs and should always be fixed.
In this tutorial, you will learn-
As shown in the above figure, iOS Testing MindMap shows all the items which tester should consider when conduct testing on iOS.
This checklist is specifically designed to test the characteristics of iOS mobile applications. Obviously, it tests only generic application characteristics and not the functionality of it.
The below figure introduces some common types of iOS testing strategy.
Automated testing is the most advantages of iOS testing. It enables you to detect the bug and performance issues quickly. The benefits of automated testing as shown below:
When the original iOS SDK was released, it lacked Unit Testing capabilities. So Apple has brought back the OCUnit unit test solution in iOS SDK version 2.2.
OCUnit is a testing framework for C- Objective in the Mac OS. The biggest advantages of an OCUnit framework are the tight integration into XCode development environment as shown below.
Some of the benefits of OCUnit are shown in below figure.
UI Automation is a JavaScript library provided by Apple Inc, which can be used to perform an automated test on real devices and on iOS Simulator. This framework is added to iOS SDK4.0. Using UI Automation, you can automate testing the application not only on the simulator but also the real device.
UIAutomation brings you these benefits:
UIAutomation instrument works from scripts, which are written in JavaScript. It simulates user events on target iOS application.
UIAutomation Cons vs. Pros
Pros | Cons | |
---|---|---|
1. | Good support for gesture and rotation | It's not open source, less support from the developer |
2. | Can run UIAutomation tests on the device, not the only simulator. | Can’t integrate with other tools extremely well |
3. | Developed by JavaScript, it is a popular programming language. |
The above figure represents some common classes in UIAutomation framework.
It is a testing without a formal test plan. Exploratory Testing is low cost testing method, but it can miss the potential bugs in your iOS application.
Exploratory Testing Cons vs. Pros
Pros | Cons | |
---|---|---|
1. | Less preparation is needed, early detect serious bugs. | Requires high skill of the tester |
2. | Don't need Test Plan speed up the bug detection. | Test coverage is low. It does not guarantee that all your requirements are tested. |
3. | Most bugs are discovered early by some sort of exploratory testing | Lack of testing documentation |
User testing is a type of Manual Testing on iOS. The purpose of this testing is to create better apps, not only bug-free apps. Below figure shows four types of User Testing
Evaluate user response to an application idea before releasing to the market. Procedures of concept testing on iOS are described as below
Usability Testing is a test how easy to use your iOS application. In iOS testing, usability test could be recorded to remember or to share with others.
There is some tools support usability testing on iOS.
Magitest, a simple iOS usability testing for sites and apps.
Delight.io, this tool can capture real user interaction on your iOS apps.
Beta Testing is the integration testing with real data to get final feedback from users. To distribute your apps for beta testing, you have to follow steps below.
-Pre-condition: If you are beta testing a final candidate for a release, be sure to validate the app before distributing it to testers.
-Find tester via service: you collect device IDs from testers and add them to Member Center
-Create ad-hoc distribution: Ad Hoc distribution allows the tester to run your app on their device without need Xcode. This step includes 2 sub-steps
-Solicit feedback from tester: Tester conduct testing and send bug reports to you. After your app is released, you can get the reports from iTunes connect.
A/B testing is one of the most powerful ways to evaluate the effectiveness of your iOS app. It uses randomized experiments with two devices, A and B.
A/B testing includes three main steps
Following tools support A/B testing on iOS.
Best practices for A/B testing
Here are some tips you should know when organizing the testing of your iOS application
This section examines a few popular myths and realities of iOS testing
Testing application on iOS and Android are the same thing.
iOS and Android are two platforms were developed by Apple Inc and Google. They are totally different. Etc test environments, test frameworks, programming languages.
Test application on iOS Simulator is enough.
iOS Simulator is not strong enough for testing an app. Because iOS Simulator has some limitations:
Everyone will download my apps on the app store because it has many features
The more features your application has, the more bugs you could get. No user will download your application if it still has many defects.
