This package provides helpers to run jest.

+BEGIN_SRC elisp

+END_SRC

Manually:

+BEGIN_SRC

M-x package-install RET jest RET

+END_SRC

• 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 = (=compile=) runs =jest-popup= and =C-c C-= (=recompile=) runs =jest-repeat=. The commands to run are configurable.
