Feature #47497
Updated by Ernesto Puerta over 3 years ago
Currently cypress framework supports "visual regression testing":https://docs.cypress.io/guides/tooling/visual-testing.html (comparing screenshots of a webpage/subpart under test with a given reference screenshot).
This will help to reduce issues with styling/brandind changes and reduce the needs of manual testing & validation.
Downsides of this approach:
* As already noted by Tiago, is that most pages are data driven, and hence dynamically changing. That makes hard to compare to fixed screenshots.
** We can either test isolated/static elements of webpages (login page, about box, navigation, forms, ...)
** Provide a given threshold for the matching algorithm (this would require manual tuning and hence is subject to making the test flapping)
** Test isolated elements without back-end data: allowing dashboard to instantiate components (blank table, static landing page, ...)
** Ensure the backend provides 'deterministic data' (feasible?)
** Hide changing data by tagging those with some class (.dynamic) and making those invisible or deterministic.
