Gulp 4 – Error – “Task function must be specified”

// Gulp task to minify all files
gulp.task('default', ['clean'], function () {
  runSequence(
    'styles',
    'scripts',
    'pages'
  );
});

If you this Standart Tasks sequence from every Tutorial using, you will be got this error message.

Fixing is so simple for simple way. Because gulp.tasks(name, deps, func) method was replaced by gulp.task(name, gulp.series/gulp.parallel)(deps, func)

// Gulp task to minify all files
gulp.task('default',
gulp.series('clean', gulp.parallel('scripts', 'styles')
));

PHPUnit Boilerplate

Of course first phpunit/phpunit to be installed. I think, local installation much better.

composer require --dev phpunit/phpunit ^7
