Why is jest looking for a test file that no longer exists?

While creating new tests, I got this error:

Determining test suites to run...Error: ENOENT: no such file or directory, stat '/home/andrew/Documents/wise-fox/The-App/src/tests/components/AlertsComponent/AlertsPages/PromoPage3.test.js'

The error is trying to look for a test file that no longer exists. I had copied a number of tests and then adapted the names of the files as well as the tests inside to fit the new files.

Previously, jest just realized that certain test files had disappeared (because of renaming), but in this case jest thinks these files still exist. I'm not sure why, and I'm not sure how to fix it.

For me it was not a snapshot issue, but a cache issue. Run

jest --clearCache

to get rid of it.

Just, delete the generated directory snapshots it will be generated where you have written YOUR_FILE_NAME.test.js.

Ah, it had something to do with the obsolete snapshot files. I deleted them manually and the tests ran just fine
