Patent attributes
Techniques are disclosed for performing visual regression testing for a software application. In one embodiment, a regression testing tool identifies a first collection of web pages from a first version of the application, and captures an image of each identified web page. The regression testing tool identifies, for one or more of the identified web pages, a corresponding web page in a second collection of web pages from a second version of the application, and captures an image of the corresponding web pages. The regression testing tool identifies differences in pixel values for images in the first collection and images in the second collection to determine differences between the image of at least one web page in the first collection and the image of the corresponding web page. The regression testing tool generates an image providing a visualization of the one or more differences.
