Test MELPA

test-cockpit.el

Run tests for multiple languages from emacs.

Synopsis

This project attempts to create a user interface to run tests for different programming languages with a consistent user interface. There are commands common to all the supported programming languages and additional settings which are language specific.

Supported languages / testing environments

So far there are modules for the following languages in connection with the indicated testing environments

  • elisp – cask / ert
  • python – pytest
  • rust – cargo
  • elixir – mix
  • JavaScript / TypeScript – jest

Planned languages

  • any other ... as soon as I need it or as soon as you implement it

Installation

Easiest way to install is from MELPA. If you have configured the MELPA sources you can just install the test-cockpit package using the package-install command.

You can of course also use straight.el. Put the following lines into your startup file.

(straight-use-package
 '(test-cockpit-<language> :type git :host github :repo "johannes-mueller/test-cockpit.el"))

where <langauge> is the programming language you need:

  • python for python - pytest
  • cask for elisp - cask / ert
  • cargo for rust - cargo
  • elixir for elixir - mix
  • npm-jest for JavaScript / TypeScript – jest

Dependencies

  • projectile as in MELPA to determine the project type
  • transient as in MELPA for the OO

Language specific

  • rust
    • emacs-toml not from MELPA but from my fork branch johmue-merges, see issues section. Install it for example this way using straight.el
(straight-use-poackage '(toml :type git :host github :repo "gongo/emacs-toml"
                              :fork (:host github
                              :repo "johannes-mueller/emacs-toml"
                              :branch "johmue-merges")))

Usage

Suggested keybindings

It is suggested that you bind the following two commands to keybindings that suit you best.

  • test-cockpit-repeat-test-or-projectile-test This should be bound to a quickly reachable keybinding, that you can find easily and quickly. It tries to the last test that the current project has been tested with. If in the current session the project has not been tested yet, a dialog is opened for you to choose the way the testing should be performed.

    If the project type is not supported it falls back to projectile-test-project.

    In either way, the test command that you give is remembered. Next time you hit your key binding, the exact same test command for the project is repeated.

  • test-cockpit-test-or-projectile-test This does open the test dialog for you to setup the test command. If the project type is not supported, it falls back to projectile-test-command. So use this if you don't want to repeat the last test, but run a different one.

Other commands

  • test-cockpit-repeat-test-or-projectile-build Like test-cockpit-repeat-test-or-projectile-test but only builds the project if the project type is not supported.

  • test-cockpit-test-or-projectile-build Like test-cockpit-test-or-projectile-test but only builds the project if the project type is not supported.

  • test-cockpit-repeat-test Like test-cockpit-repeat-test-or-projectile-test but does not fallback to projectile.

  • test-cockpit-dispatch Like test-cockpit-test-or-projectile-test but does not fallback to projectile.

You can also use the following commands to run tests in a more manual way

  • test-cockpit-test-project to run the whole test suite.
  • test-cockpit-test-module runs only the tests of the current module.
  • test-cockpit-test-function runs only the test of the function at point.
  • test-cockpit-repeat-test repeats exactly the previous test run.

If the current function at point or the current module cannot be determined, the last tested module resp. last tested function are tested. If there are no last tests, an error message is thrown.

Dape support

There are stubs to make use of the Dape package to call the recent test run in a Dape debugging session. So far, only the python backend supports this feature.

You can call this either using the transient UI or by the command test-cockpit-dape-debug-repeat-test.

Status

The development started more than a year ago in early 2021. Since then I have used it for my daily work and added new features every now and then. It turns out to work smoothly and to be quite useful.

Interesting feature ideas

  • Test discovery
  • Parsing test results to determine failed tests
  • Generalizing it to a more comprehensive build-cockpit also doing simple builds and things like release uploads.

Check the issues for more short term goals.

Limitations

Lots. I implement stuff as soon as I need it and have some time.
