![]() ![]() Incorporate everything in a single test run which runs storybook, run cypress to generate new screenshots and then the diff tool and fail if there is a regressionĪdd an update command that runs cypress run and c/p the new images into the base folder. here's a rough idea of what's left to do: If you feel this could be included in grommet then i will continue working on this. so if you run again visual regression then you shouldn't get any errors If you run cypress run then you set of images will be produced in cypress/screenshots/new which are going to be correct this time. Since the circular meter is wrong, it will produce an error and create the a diff image as here the following if you run yarn visual-regression diff images will be deleted and the differ tool will try to identify regressions. in diff there are the images produced by blink-diffįor showing results i have changed the one of the new images to not be correct.OS: Mac OS 10. new are the images produced by the test run Developers Homepage: Visual Differ System Requirements for VisualDiffer for Mac.in cypress/screenshots there are 3 sets of folder:.magic is in for now i haven't submitted a PR but i can if you think it can facilitate discussion.i run the tests on the public storybook for now. So i manage to take accurate screenshots. Maybe end to end testing could be used for further accessibility tests (inject axe-core in a page with components and verify there are no warnings etc).This could also be used for cross-browser testing.compared to snapshot testing it will be probably not that obvious to present results and diffs.in order to make the diffs the "snapshots" would need to be commited in the repository.otoh it seems that using the dashboard is optional their dashboard service is paid with no mention for free pass on open source projects.More context cypress-io/cypress#495 Trade-offs It doesn't provide an in-house image differ but it seems this could be done with another tool such as blink-diff, or some other in-development cypress plugins. can take screenshots/videos during test runs.provides the necessary for end to end testing, might even be possible to use jest as assertions.It seems cypress provides enough tools to achieve something similar to what is described above: I am thinking that there could be a test-suite that tests some components and takes some screenshots with the aim to compare images at each run and try and detect visual regressions. It could be interesting to add some end to end tests with the goal to introduce some visual regression tests.
