Unit Testing with Pressmatic

  • Updated 20 August 2016

Installing Composer on Pressmatic

  1. SSH into the Pressmatic box
  2. $ apt-get update
  3. $ apt-get install curl php5-cli git subversion
  4. $ curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Installing PHPUnit with Composer

  1. $ composer global require "phpunit/phpunit=4.8.*”
  2. $ export PATH="$PATH:$HOME/.composer/vendor/bin"

Setting Up Plugin Unit Tests

1. Generate the Plugin Test Files

$ wp scaffold plugin-tests <plugin-name>

2. Initialize the Environment Locally

$ cd $(wp plugin path <plugin-name> --dir) $ bash bin/install-wp-tests.sh wordpress_test root root localhost latest

3. Run the Plugin Tests

$ phpunit

TROUBLESHOOTING

1. Running phpunit errors out

Running phpunit could result in a fatal error stating that some core WordPress files in /tmp directory were not found.

It probably means that the bash bin/install-wp-tests.sh wordpress_test root root localhost latest command failed and you might have to delete the "wordpress-test" database as well as /tmp/wordpress and /tmp/wordpress-tests-lib directories and re-run the bash bin/install-wp-tests.sh wordpress_test root root localhost latest command again.
