gulp-mocha-c8

gulp-mocha-c8 is a gulp plugin that runs mocha tests through c8.

NPM

Usage

gulp-mocha-c8 provides a function to run mocha tests with c8 within a gulp task.

var mochaC8 = require('gulp-mocha-c8');

gulp.task('default', () =>
	gulp.src('test.js', {read: false})
		// `gulp-mocha-c8` needs filepaths so you can't have any plugins before it
		.pipe(mochaC8({ 
            mochaOpts: {
                reporter: 'json'
            },
            c8Opts: {
