Videos & posters

Learn to utilize the poster image if a video is playing within your tests while taking screenshot.

To enable the display of content for <video> elements, videos without a poster attribute will have the current frame serialized into an image, automatically setting it as the poster attribute. This ensures that videos have a designated image for display when capturing screenshots.

This scenario can lead to flaky tests when the video is playing. Percy’s SDKs capture the current frame of the video when percySnapshot is called. If this causes flakes in your tests, the recommended solution is to provide your own poster image for the video. This ensures that the same image is captured and used when screenshots are captured.
