Behat Test Runner
Behat Test Runner is essentially a Behat context class which provides steps for testing a Behat extension. You can put together a feature file and behat.yml configuration, than the test runner will start a second Behat process to evaluate the created feature file.
Installation
Install by adding to your composer.json:
composer require --dev bex/behat-test-runner
Configuration
Include the context file in behat.yml like this:
default:
suites:
default:
contexts:
- Bex\Behat\Context\TestRunnerContext
You can configure the test web browser to be used for opening the pages, like this (optional):
default:
suites:
default:
contexts:
- Bex\Behat\Context\TestRunnerContext:
browserCommand: %paths.base%/bin/phantomjs --webdriver=4444
You can configure the working directory like this (optional):
default:
suites:
default:
contexts:
- Bex\Behat\Context\TestRunnerContext:
workingDirectory: path/to/your/working/dir # if not provided then a temporary working dir is autogenerated
Usage
Simply use the necessary steps from the context file to put together your feature.
An example:
Feature: Visiting a page on the website
In order to demonstrate how to use test runner
As a developer
I should open a page and verify the content of it
Scenario: Visiting the index.html page
Given I have the file "index.html" in document root:
"""
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Test page</title>
</head>
<body>
<h1>Lorem ipsum dolor amet.</h1>
</body>
</html>
"""
And I have a web server running on host "localhost" and port "8080"
And I have the feature:
"""
Feature: Test runner demo feature
Scenario:
Given I open the index page
Then I should see the content "Lorem ipsum" on the page
"""
And I have the context:
"""
<?php
use Behat\MinkExtension\Context\RawMinkContext;
class FeatureContext extends RawMinkContext
{
/**
* @Given I open the index page
*/
function firstStep()
{
$this->visitPath('index.html');
}
/**
* @Then I should see the content :content on the page
*/
function secondStep($content)
{
$this->getMink()->assertElementContains('h1', $content);
}
}
"""
When I run Behat
Then I should not see a failing test
