Unlike Android app testing, iOS App Testing is different and more complex. Testing services use many tools to tackle the set of challenges.
Here are top mobile automation tools for iOS mobile app testing services.
-

UI Automation
UI Automation is an Apple sanctioned way of performing iOS functional testing. You might be familiar with typical functional tests or black-box tests. In such tests you’ve to write code that simulates an end user navigating your app, in fact you’re doing a kind of UI Automation there.
You have to use instruments to utilize UI Automation. For example, tools that come with Xcode can be used for this purpose.
iOS code is written in Objective – C or Swift, whereas UI Automation tests are written in JavaScript. This is the only drawback of UI Automation.
Since UI Automation is lightly documented, there is chance for experiencing technical problems. As there is not much of a community around it, you are devoid of technical support as well.
If new versions of XCODE are launched, Apple may provide updates to UI Automation. In the event, apple doesn’t give you technical support; you can rely on third party ways to test your iOS code.

OCmock
OCmock is a popular iOS app testing tool. As it as an efficient tool, you can use it for stubbing out and making mock objects of stuff. For instance, it works like a code that leverages in a remote API.
There are codes that relies on a User Interface (UI), you can utilize OCmock tool for such codes. It’s not easy for you to represent yourself like UI objects.
KIF is an amazing tool for iOS App Testing Services. It can be used as an alternative to UI Automation.
It’s an open source and third party tool as well.
As you write tests in UI Automation, this tool also enables you to write tests somewhat in the similar fashion.
KIF depends on accessibility labels much similar to UI Automation. Since you are allowed to define your application, you can design your app that is accessible for visually impaired persons as well. Instructions for using the app can be prompted through audio queues.
KIF has a couple of advantages over UI Automation. You have to swap languages between Objective – C and JavaScript in UI Automation. As KIF is written in Objective – C which supports Swift too, you don’t need to swap between languages.
