Testing

We use WordPress plugin unit test to write and run our tests.

Read more on Plugin Integration Test and install it’s dependencies on your system: PHPUnit, curl, svn, git, php and apache

Install temporary WordPress and it’s database

There is a bash script located in bin/install-wp-tests.sh, This script will install a WordPress in your system temp folder.

You should run this script to be able to run your tests. Based on it`s documentation this how it works:

usage: ./bin/install-wp-tests.sh <db-name> <db-user> <db-pass> [db-host] [wp-version] [skip-database-creation]

so in my example it would be:

./bin/install-wp-tests.sh realtyna-test root admin 127.0.0.1 6.1.1

after you ran this command in your terminal you can use phpunit. you have 2 options to do so:

• using phpunit in terminal
• using vendor/bin/phpunit in terminal

bootstrap tests

Go on and take a look at tests/bootstap.php.

this file is responsible to load WordPress before running your tests. feel free to dig deeper in this file.

if you look at line 31-33 you see that it’s loading your plugin. So if you need to include another plugin in your test you should enter it`s path in this function.

Test Naming

Take a look at phpunit.xml.dist, you can see on line 12 that PHPUnit will look for files that ends with Test.php in tests folder.

You can change that if you want.
