npm test <ng-project> -- --testFile "file-name-part"
yarn test -- <file-name>n order to run a specific test, you'll need to use the jest command. npm test will not work. To access jest directly on the command line, install it via npm i -g jest-cli or yarn global add jest-cli.
Then simply run your specific test with jest bar.spec.js.
Note: You don't have to enter the full path to your test file. The argument is interpreted as a regexp. Any part of the full path that uniquely identifies a file suffices.
