PHPSpec auto-testing Gulpfile

Gulpfile.js

var gulp = require('gulp');
var phpspec = require('gulp-phpspec');
var run = require('gulp-run');
var notify = require('gulp-notify');

gulp.task('test', function() {
   gulp.src('spec/**/*.php')
       .pipe(run('clear'))
       .pipe(phpspec('', { notify: true }))
       .on('error', notify.onError({
           title: 'Dangit',
           message: 'Your tests failed!',
           icon: __dirname + '/fail.png'
       }))
       .pipe(notify({
           title: 'Success',
           message: 'All tests have returned green!'
       }));
});

gulp.task('watch', function() {
   gulp.watch(['spec/**/*.php', 'src/**/*.php'], ['test']);
});

gulp.task('default', ['test', 'watch']);

I had to change line 8 for this:
.pipe(run('clear').exec())

I had to change line 8 for this:
.pipe(shell('clear'))
and conseguntely
insert the following line
var shell = require('gulp-shell');

Like @carnar I too had to change line 8 to .pipe(run('clear').exec())

For windows, we can use https://gist.github.com/mishbah/b144e73fcc2bb2caf393

Yes I had to change line 8 as well .pipe(run('clear').exec()).

THis does not work anymore with Gulp4

Use this: https://github.com/fetzi/phpspec-watcher

Gulp 4

var gulp = require('gulp');
var phpspec = require('gulp-phpspec');
var run = require('gulp-run');
var notify = require('gulp-notify');

gulp.task('test', function(done){
	gulp.src('spec/**/*.php')
		.pipe(run('clear').exec())
		.pipe(phpspec('', {notify:true}))
		.on('error', notify.onError({
			'title': 'Failed!!!',
			'message': 'Your test failed'
			//'icon': __dirname + '/fail.png',
		}))
		.pipe(notify({
			'title': 'Success',
			'message': 'All tests have returned green'
		}));
	done();
});

gulp.task('watch', function(){
	gulp.watch(['spec/**/*.php', 'src/**/*.php'], gulp.series(['test']));
});

gulp.task('default', gulp.series(['test','watch']));

Gulp 4

var gulp = require('gulp');
var phpspec = require('gulp-phpspec');
var run = require('gulp-run');
var notify = require('gulp-notify');

gulp.task('test', function(done){
	gulp.src('spec/**/*.php')
		.pipe(run('clear').exec())
		.pipe(phpspec('', {notify:true}))
		.on('error', notify.onError({
			'title': 'Failed!!!',
			'message': 'Your test failed'
			//'icon': __dirname + '/fail.png',
		}))
		.pipe(notify({
			'title': 'Success',
			'message': 'All tests have returned green'
		}));
	done();
});

gulp.task('watch', function(){
	gulp.watch(['spec/**/*.php', 'src/**/*.php'], gulp.series(['test']));
});

gulp.task('default', gulp.series(['test','watch']));

Great! Thanks!
But on macOS Catalina you don't need .exec() in line 8.
Maybe .exec() is for windows? If somebody knows pls put in the comments.

By the way you don't need the gulp-run here, because gulp-phpspec has:
API options.clear
Type: Boolean (Default: false)
Clear console before executing command

If you need an example or more phpspec options, i have a gist with my gulpfile here: https://gist.github.com/cofirazak/8dcf9b5204c7bdafd0f4bcff636a55ee

As a minor fix i would also convert var to const.
And no need in extra quotes around title, message, icon and message json keys.
