jest: Run the tests whose names match the given regular expression.
$ jest --testNamePattern ${regular_expression}
try on your machine
This command uses the Jest testing framework to run tests that match a specific regular expression pattern for the test names.
Here's the breakdown of the command and its components:
jest
: This is the executable command for running Jest, a popular JavaScript testing framework.--testNamePattern
: This option allows you to specify a regular expression pattern to match the test names against.${regular_expression}
: This is a placeholder indicating that you should replace it with your desired regular expression pattern. Regular expressions are a powerful way to search, match, and manipulate text patterns in strings.- The overall command would be something like
jest --testNamePattern ^test-
which would only run tests whose names start with "test-".
By using this command, you can selectively run specific tests based on matching their names against a regular expression pattern.

never run a command you are not sure if it is safe.
