Test any app, just click and play
Build automated tests for your apps regardless of their underlying technology, complexity or interactivity. We are the first to support all the latest technologies - HTML5, AJAX, Silverlight and WPF! Test Studio is the one stop shop for testing JavaScript calls, Telerik controls, dynamic page synchronization, client-side behaviors, complex UI virtualizations and XAML animations.
Why functional testing with Test Studio?
Productivity gains
Boost your productivity with unique features like automatic element detection, on-the-spot validation, element abstraction and reuse, DOM Explorer, test step builder, and more.
Cross-browser testing
Be browser independent
No need to tweak your tests for different browsers any more – have a test recorded once and execute against: Internet Explorer, Firefox, Safari and Chrome.
Whole team testing
Export projects in Visual Studio and check in tests in the source repository.
The test is saved in the project folder from where developers can further customize
and extend it.
Visual Studio plugin for coding pro’s:
Test Studio ships with a developer-focused solution that gives you maximum control over your code and tests. It's where you need it most - tightly integrated in Visual Studio.
The powerful built-in test recorder can convert your tests to .NET code which can be further customized or extended in Visual Studio if needed.

the execution time of your manual tests by automating time-consuming repetitive tasks.

Exploratory testing
Test Studio Explore is an in-browser extension that helps you report bugs directly from your application. Attach screenshots, ideas, and annotations, while browsing. Share your feedback via email, or export it to Word and PDF. All this with a simple click of a button – no additional installations are needed.

Much more efficient regression testing
Test maintenance is smoother with Test Studio. We don’t use absolute coordinates which guarantees your tests will not break if the application layout changes. Better yet, all elements are stored in the "Elements repository". If there are multiple tests that use the same element, it will be referenced from the "Elements Explorer" instead of being duplicated in the test.

Test scheduling, execution and reporting
Leverage multiple machines to execute test runs in parallel saving vast amounts of execution time. Test Studio allows you to schedule and execute tests across the entire testing environment. Automatically collect results into a centralized repository and then analyze them on your local machine! Get email notifications upon run completion.

Powerful test recorder
Test Studio introduces a next-gen approach to test recording with its built-in recording surface. Not only are you able to create your tests with point-and-clicks, you can easily add conditional logic without writing a single line of code, or extract a value from a page element to be used later in the test.
