Gemini

Gemini is a utility for regression testing the visual appearance of web pages.

Gemini allows you to:

• Work with different browsers
• Test separate sections of a web page
• Include the box-shadow and outline properties when calculating element position and size
• Ignore some special case differences between images (rendering artifacts, text caret, etc.)
• Gather CSS test coverage statistics

Gemini was created at Yandex and is especially useful to UI library developers.
