[[https://melpa.org/#/jest-test-mode][file:https://melpa.org/packages/jest-test-mode-badge.svg]]

Emacs minor mode for running jest (Nodejs test framework). Inspired by =ruby-test-mode= and =cider-test=.

** Features

Uses =npx jest= to execute tests. This respect your project's version of =jest=.
Keybindings to execute tests for the entire project, a test module, or a top-level test/describe block.
File references in the Test Execution Buffer support jump to definition.

** Keybindings jest-test-mode comes with some default keybindings:

| Binding | Action | |-------------+------------------------------------------------------------------| | ~~C-c C-t n~~ | Runs tests in the current buffer. | | ~~C-c C-t p~~ | Runs all tests in the project. | | ~~C-c C-t t~~ | Runs the it/test/describe block at the current point. | | ~~C-c C-t a~~ | Re-runs the previous test command. | | ~~C-c C-t d n~~ | Runs tests in the current buffer with node debugger. | | ~~C-c C-t d t~~ | Runs the describe block at the current point with node debugger. | | ~~C-c C-t d a~~ | Re-runs the previous test command with node debugger. |
