Behat Command Runner extension

This is a proof-of-concept - use with caution!, _(*1)

Extension to run commands at hooks in test lifecycle, useful for cache clearing, database setup, teardown, etc..., _(*2)

Installation

Require package adamquaile/behat-command-runner-extension via composer:, _(*3)

composer require --dev "adamquaile/behat-command-runner-extension *@dev"

Add configuration to your behat.yml. This example shows the full configuration options., _(*4)

default:
    extensions:
        AdamQuaile\Behat\CommandRunnerExtension:
              beforeSuite:
                  - echo "beforeSuite"
                  - { command: 'ping example.com', background: true }
              afterSuite:
                  - echo "afterSuite"
              beforeFeature:
                  - echo "beforeFeature"
                  - { command: 'ping example.com', background: true }
              afterFeature:
                  - echo "afterFeature"
              beforeScenario:
                  - echo "beforeScenario"
                  - { command: 'ping example.com', background: true }
              afterScenario:
                  - echo "afterScenario"

A symfony2 example

This example runs phantomjs for our javascript behat tests, and also creates and recreates a test database for each feature., _(*5)

For speed, the database is copied back into place after the first run during setup rather than using doctrine each time., _(*6)

For more isolation, you could do this copying on beforeScenario rather than beforeFeature., _(*7)
