Fail test with no snapshot file

[vladimirvolek]

Is there any option to fail the test if there is NO snapshot?

[jackjocross]

Interesting, not currently. Are you envisioning that at the end of your tests, if any snapshot files exist that were not compared on the run the test would fail?

[obartra]

Yeah it would be really useful to have a flag (to use on CI) where if images are missing the tests fail but working locally (without a flag) it would create missing images

Cool, that makes sense. I think we might want to hook into Cypress' test:after:run event to perform these checks.

Any update on this?

I'm interested in this as well. I run Cypress in a CI environment, and I'd like to see a failure on my PRs when new snapshots are created. Two reasons:

• I'd like to be notified that I need to check the new snapshot to make sure it looks as expected.
• A new snapshot could indicate a regression (e.g. an unexpected change in the name of the snapshot, a test that runs when it should have been skipped, etc.)

Yes, this would be a very useful option ... and I think it should be default behavior: If you don't find the file to match fail the test. Then you can use the updateSnapshots=true option and update the screenshots locally. @jaredpalmer Is there some option to add a quick fix for this?

@lexanth would you be willing to create a PR with your solution from df2f147? That would be very helpful for all people using this package in CI :)

Hey Friends, It seems that this feature is not yet implemented in this library. Is there any fork that has this feature?

[vladimirvolek]

The library is ded.
