Rerun tape tests when files change

tape-watch is an auto-test runner for tape. It will re-run your tests when any of the files in your project changes. This is better than using watch or nodemon: it will reload your tests in the same Node.js process, saving you precious startup time.

Usage

Can happily live in your project (--save-dev) or globally (-g). I prefer global, since it's compatible with every project with tape in it.

npm install -g tape-watch

Reference

Usage:
  $ tape-watch <files> [options] -- [options for the test]

Options:
  -p, --pipe PACKAGE        pipe to this package
  -o, --out CMD             output to this file/cmd
  -R, --refresh PACKAGE     ensure this PACKAGE gets refreshed
  -r, --require PACKAGE     require a PACKAGE before startup
  -1, --once                only run once
  -w, --watch               cancel out --once
  -c, --clear               clear console between test runs

Other options:
  -h, --help                show usage information
  -v, --version             print version info and exit

Examples:

tape-watch test/index.js
tape-watch test/index.js -p tap-spec
tape-watch test/index.js -o '| tap-spec --color'

# ensure require('jquery') and require('react') always gets reevaluated
tape-watch test/index.js -r jquery -r react

# run all test files in test/
tape-watch 'test/**/*.js'

Using with Babel

Use the -r (--require) flag with babel-register.

tape-watch -r babel-register

Before you do this, of course, you'll need to install the requisite modules first.

npm install --save-dev babel-register babel-preset-es2015

/* package.json */
  "babel": {
    "presets": ["es2015"]
  }

Adding npm test

Add this to your package.json:

  "scripts": {
    "test": "tape-watch -1 test/*"
  }

You can now run tests with npm test, or make it auto-run with npm test -- --watch.
