npm run test for jest code example

Example: jest run specific test

From the command line, use the --testNamePattern or -t flag:

jest -t 'fix-order-test'
This will only run tests that match the test name pattern you provide. It's in the Jest documentation.

Another way is to run tests in watch mode, jest --watch, and then press P to filter the tests by typing the test file name or T to run a single test name.

If you have an it inside of a describe block, you have to run

jest -t '<describeString> <itString>'
