๐ Require using .only and .skip over f and x.
๐ผ This rule is enabled in the โ
recommended
config.
๐ง This rule is automatically fixable by the
--fix CLI option.
Jest allows you to choose how you want to define focused and skipped tests, with multiple permutations for each:
- only & skip:
it.only,test.only,describe.only,it.skip,test.skip,describe.skip. - 'f' & 'x':
fit,fdescribe,xit,xtest,xdescribe.
This rule enforces usages from the only & skip list.
Rule details
This rule triggers a warning if you use one of the keywords from the 'f' & 'x' list to focus/skip a test.
