Mink Driver testsuite

This is the common testsuite for Mink drivers to ensure consistency among implementations.

Usage

The testsuite of a driver should be based as follow:

{
    "require": {
        "behat/mink": "~1.7"
    },
    
    "require-dev": {
        "mink/driver-testsuite": "dev-master"
    },

    "autoload-dev": {
        "psr-4": {
            "Acme\\MyDriver\\Tests\\": "tests"
        }
    }
}
<!-- phpunit.xml.dist -->
<?xml version="1.0" encoding="UTF-8"?>

<phpunit colors="true" bootstrap="vendor/autoload.php">
    <php>
        <var name="driver_config_factory" value="Acme\MyDriver\Tests\Config::getInstance" />

        <server name="WEB_FIXTURES_HOST" value="http://test.mink.dev" />
    </php>

    <testsuites>
        <testsuite name="Functional tests">
            <directory>vendor/behat/mink/driver-testsuite/tests</directory>
        </testsuite>
        <!-- if needed to add more tests -->
        <testsuite name="Driver tests">
            <directory>./tests/</directory>
        </testsuite>
    </testsuites>

    <filter>
        <whitelist>
            <directory>./src</directory>
        </whitelist>
    </filter>
</phpunit>

Then create the driver config for the testsuite:

// tests/Config.php

namespace Acme\MyDriver\Tests;

use Behat\Mink\Tests\Driver\AbstractConfig;

class Config extends AbstractConfig
{
    /**
     * Creates an instance of the config.
     *
     * This is the callable registered as a php variable in the phpunit.xml config file.
     * It could be outside the class but this is convenient.
     */
    public static function getInstance()
    {
        return new self();
    }

    /**
     * Creates driver instance.
     *
     * @return \Behat\Mink\Driver\DriverInterface
     */
    public function createDriver()
    {
        return new \Acme\MyDriver\MyDriver();
    }
}

Some other methods are available in the AbstractConfig which can be overwritten to adapt the testsuite to the needs of the driver (skipping some tests for instance).

Adding Driver-specific Tests

When adding extra test cases specific to the driver, either use your own namespace or put them in the Behat\Mink\Tests\Driver\Custom subnamespace to ensure that you will not create conflicts with test cases added in the driver testsuite in the future.
