Question

How to install phpunit?

I read documentation https://github.com/sebastianbergmann/phpunit, but have an error:

>pear upgrade PEAR
Nothing to upgrad

Old answer (2014): It's said that phpunit will not be available via PEAR since December 2014.
So it's easy to install it using composer:

composer global require "phpunit/phpunit=4.1.*"

Update 2019: it should be installed as a local (for your project) development package:

 composer require --dev phpunit/phpunit ^8

Update 2020: it should be installed as a local (for your project) development package: composer require --dev phpunit/phpunit ^9.3
