  • Open UI Automation

    I guess all of you who have worked on UI testing know the “locator” problem. In order to find an element in the DOM you need to provide a locator and usually it’s an XPath string.

In order to avoid such situations as much as possible my colleagues Peter Savage, Ronny Pfannschmidt and Karel Hala have developed a specification for frontend developers Open Web UI Design Specification for Enabling Automation (OUIA). If your application complies with OUIA it will have predictable locators and the behavior. This significantly simplifies writing automated tests.
