Why iOS?

iOS is the most widely used operating system and offers n number of features with the latest update.

From AI/ML and IoT to Augmented Reality, Cloud Integrated Apps, Chatbot, Apple Pay and iOS security, it has various features and advancements that can easily make a person feel its necessity. Therefore, there are many apple users, due to which testing of the application plays a vital role in today’s lives.

As you all are aware of the fact that Android is widely used in the market, why choose iOS? The answer to the question goes as follows:

  • Software and Hardware integration is easy in iOS than in Android. The software is very refined and makes the best use of the underlying hardware.
  • It is effortless to use compared to Android as the UI is simple with fewer customizations, making it easy to adopt for new users.
  • When it comes to security, iOS is built upon Linux, and Apple has enhanced the already inherent security features available in Linux.

iOS Automation Testing

As the name suggests, iOS automation testing implies performing automated testing for iOS devices only. It is imperative for a tester to understand the technical and functional aspects before writing the test cases. You should also ensure that the performance metrics are on par with the actual and expected results of the test cases.

This testing is the same as any other automation testing involving bug detection and resolving the issue. There are 4 key aspects that should be considered while testing an iOS application. They are: Hardware, Software, UI, and functionality.

The very basic thing here is that the test cases written should be compatible across all the iOS devices based on their functional and technical aspects from all angles.

You can implement iOS automation testing with following approaches:

What Are iOS Testing Tools?

iOS testing tools are software applications or frameworks designed to evaluate the functionality, performance, and quality of iOS applications. 

They help streamline and automate the testing process and ensure that iOS apps meet the desired standards and user expectations.

They allow you to create test scripts/test cases, measure app performance, and simulate user interactions to identify and address potential issues or inconsistencies in the application.

Why Need iOS Testing Tools?

iOS app testing can be done both manually or using mobile testing tools that support iOS app testing. Manual testing involves testers manually evaluating the app’s functionality and performance to find any bugs. But, there are times when manual testing becomes repetitive or complex. At those times it is better to switch to automated testing to improve the testing speed while the manual testers can focus on other important testing activities. 

Automated testing is highly recommended for fast, accurate, and reliable testing. It uses iOS app testing tools to create and run automated test scripts that simulate user interactions and scenarios, automating repetitive, complex, and time-consuming tasks. 

You can use these tools to automate different testing types, such as 

How To Pick The Right iOS Testing Framework For You

Look into these main factors before you pick an iOS testing tool for your application,

  • Price
  • Learning curve
  • Supported platforms
  • Coding skill requirements


Price is a crucial factor every business should consider based on their budget and project requirements. There are a variety of free and paid tools in the market. Choose a tool that aligns with your testing requirements and budget. 

Evaluate the price associated with each testing tool as they come with licensing fees or additional costs for advanced features. Also, choose a tool that gives you the highest test ROI because that also matters the most.

Learning Curve

Choose a testing tool that is easy to learn and use. Not every tool offers a simple and intuitive user interface for end-users. So check the learning curve of the testing tool by looking at the reviews, ease of use, and, if possible, try out free trials. 

Plus, using a codeless test automation tool will make automation testing more accessible for both technical and non-technical users in the team.

Also, the amount of time it takes to learn a tool impacts the budget and time it requires to train and onboard new users and others involved in testing. 

Supported Platforms

Make sure the testing framework supports iOS testing. Check for compatibility with different iOS versions and devices. 

Some frameworks may be limited in terms of supported platforms. Choose a tool like Testsigma that supports web, mobile (Android, iOS), desktop, and API testing in one place. 

Coding Skill Requirements

Evaluate whether a framework is entirely code-based, codeless, or a hybrid. Your decision should align with your team’s skills, too. A code-based tool requires testers to have strong coding skills to create test scripts. It can be a suitable choice if you have a highly experienced QA team with solid coding knowledge. 

If not, I would recommend using a testing tool that supports both codeless and code-based testing in one platform. It makes test automation accessible to everyone, also boosts the feedback structure, and enhances the testing process. For example, Testsigma, TestComplete, Katalon, etc.

This popular iOS testing framework smoothly integrates with XCode’s testing workflow. Apple developed XCTest, and it turns out to be well-supported. This is also kept in sync with the iOS application framework as it comes with Apple’s suite.


  • XCTest is relatively simple to integrate into an app as it comes with XCode by default.
  • Unit, UI, regression and performance testing are possible.


  • It is necessary that testers should have developer skills because  XCode is a complex software that needs technical expertise.
  • Object-C and Swift are the only programming languages supported with XCTest.

Use case Scenario

In the below scenario, to test the time taken by your code, call the measure(_:) inside your test method, and execute the application code inside the block argument. To measure performance using other metrics, including memory use and amount of data written to disk, call measure(metrics:block:).

class PerformanceTests : XCTestCase {
func testCodeIsReliable() {
self.measure() {
// performance-related code
