rossille · rossille · commit bd49cd72e780 · 2016-04-03T16:17:10.000+02:00
Changes highlights:

package.json
- Add devDependencies: mocha (test runner) and istanbul (to measure code
coverage)
- Add npm "test" lifecycle script: now "npm test" runs the mocha tests,
wrapped with istanbul to measure coverage. Test coverage is not amazing
so far, but that's a start :=)
