Telerik's free Test Studio for iOS offers an exciting new tool for developers. It allows you to record and execute automated tests in your mobile apps and websites. Users can also use the tool to provide feedback to your team as they test.

Telerik worked closely with Apple to get this app into the iOS App Store, and it provides an astonishing utility to anyone who develops. It allows you to run tests in separate apps that you create. It also works with stand-alone websites.

To make your app Test Studio-compatible, you do need to compile in a small static library so Test Studio can see it on your device or in the simulator. Website testing works straight out of the box. The test suite is aware of all installed applications that have been prepared for use with these tools.

In the testing mode, you create a series of validation sequences. These sequences consist of interaction events, which you can record directly from your app, and verification tests, which you specify in the built-in action editor. These tests ensure that user interactions match certain expectations that you set.

A special-purpose menu, which appears directly in-app, lets you pause, add tasks, and review the steps that you have already taken. Anyone who's used a UI recording tool will be familiar with this kind of interface. Nicely, the menu can be easily flipped out of your way if it obscures things you need to work with. A lot of work has gone into making this suite usable for developers.

This app works in the simulator as well as on devices; it also works in off-line mode, so you can create your tests while on-the-go if you're away from the Internet.

Once recorded, you can then play back these interactions directly to the app or website. The integrated library will simulate all user interactions in the test, and confirm that the interface matches all your verification targets.
