This package provides helpers to run jest.

Installation

jest.el is available from melpa.

With use-package:

(use-package jest)

Manually:

M-x package-install RET jest RET

Overview

The main command is jest-popup, which will show a dispatcher menu, making it easy to change various options and switches, and then run jest using one of the actions.

• jest (run all tests)
• jest-file (current file)
• jest-file-dwim (‘Do what I mean’ for current file)
• jest-function (the test function where the pointer is now, fallback to current file)
• jest-last-failed (rerun previous failures)
• jest-repeat (repeat last invocation)

A prefix argument causes the generated command line to be offered for editing, and various customization options influence how some of the commands work. See the README.org for detailed information.

Jest Minor Mode

Jest minor mode binds compilation-related commands such as compile-command and recompile-command to Jest commands, so that, for example C-c <RET> (compile) runs jest-popup and C-c C-<RET> (recompile) runs jest-repeat. The commands to run are configurable.

(use-package jest
  :after (js2-mode)
  :hook (js2-mode . jest-minor-mode))
