What is jest's equivalent of `mocha -g` (grep option)?

Question

Per the Mocha documentation, I can run a group of tests with a particular pattern in their describe/suite or it/test block using mocha -g. For example mocha -g 'filtering usernames' only the tests with filtering usernames in their names.

Test Filters
  --fgrep, -f   Only run tests containing this string                   [string]
  --grep, -g    Only run tests matching this string or regexp           [string]
  --invert, -i  Inverts --grep and --fgrep matches                     [boolean]

I am now working on projects using jest.

How can I run tests whose name matches a pattern in Jest?

Looking through the Jest docs I've found the answer to this one myself - keeping the question up as the answer may be useful for others:

From https://jestjs.io/docs/en/cli

Run tests that match this spec name (match against the name in describe or test, basically).

jest -t name-of-spec
