Current, I installed phpunit. i use OS win 10. I think i installed new version from https://phpunit.de/ (current version 5.6, beta 5.7). But when check version with command
Just download the latest version and replace the old one. It is provided from the phpunit homepage.
$ wget https://phar.phpunit.de/phpunit.phar $ chmod +x phpunit.phar $ sudo mv phpunit.phar /usr/local/bin/phpunit
You are in the latest version. To check version you can use
$ phpunit --check-version
