Behat Command Runner extension

This is a proof-of-concept - use with caution!

Extension to run commands at hooks in test lifecycle, useful for cache clearing, database setup, teardown, etc...

Installation

Require package adamquaile/behat-command-runner-extension via composer:

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

Add configuration to your behat.yml. This example shows the full configuration options.

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.

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

For more isolation, you could do this copying on beforeScenario rather than beforeFeature.

default:
    extensions:
        AdamQuaile\Behat\CommandRunnerExtension:
              beforeSuite:
                  - rm app/var/test.db 
                  - php app/console --env=test doctrine:database:drop --force
                  - php app/console --env=test doctrine:database:create --force
                  - php app/console --env=test doctrine:schema:update --force
                  - cp app/var/test.db app/var/test.initial.db
                  - { command: 'phantomjs-1.9.7-linux-x86_64/bin/phantomjs" --webdriver=4444  >"phantomjs.log"', background: true }
              beforeFeature:
                  - cp app/var/test.initial.db app/var/test.db
