Hybrid Element Find Logic

By creating automation elements that use both web locators and images, flaky and fragile tests are a problem of the past.

  • Create powerful and rich web queries by using the technologies you know. Supported locators are CSS selectors, HTML attributes, Tag names, XPath and combinations of the above.
  • Element image is automatically set for each element. When it is time for test execution, elements in your application will be located by the powerful image comparison engine and the web query built for that element.
  • The hybrid element detection approach significantly lowers the probability of failure and allows you to perform maintenance in your own time.
  • Image first strategy. Prioritize element location by image only for situations where it’s impossible to create a stable web query.

Responsive Website Testing

Responsive web design is crucial to the success of your applications today. But testing each release for device compatibility can be a tedious task for your entire team. Test Studio helps you future-proof your application’s responsive web design for the modern mobile world with responsive web testing.

Check your responsive web application’s behavior under different form factors without repetitive manual tasks or device switching. Make sure your website scales when the screen size or resolution changes and check its layout and behavior. To simulate different browsers, simply choose from several predefined screen sizes or create the custom ones that you need for your responsive test scenarios.
