Test vs. Test
A New Test Type
A New Test Type “BDD is a second-generation, outside–in, pull-based,
multiple-stakeholder, multiple- scale, high-automation, agile methodology. It describes a cycle of interactions with well- defined outputs, resulting in the delivery of working, tested software that matters”
A New Test Type
A New Test Type Behavior-driven development specifies that tests of
any unit of software should be specified in terms of the desired behavior of the unit.
What’s The Scenario Given I am in a talk When
the speaker is presenting And he glares at me I remain quiet
What’s The Scenario Tests are readable by people first Non-technical
people can be taught the DSL
Getting Started?
Behat
What Is It? “A PHP framework for testing your business
expectations” http://behat.org
How Do I Use It 1. Install it via Composer
2. ??? 3. Profit!
How Do I Use It? 1. Install via Composer 2.
Create a Feature with a Scenario 3. Run your test 4. Profit!
Installing
Create Your Feature File
What Is A Scenario? A test that covers specific behavior
you wish to test
What Is A Scenario?
First Run
Steps To Implement
Steps To Implement
Write Some Code
Scenario Passes!
What About Web Testing?
Mink Framework for doing web acceptance testing Sits between Behat
and browser emulator http://mink.behat.org
Installing
Browser Emulation
How does it help? Provides a common API for browser
interaction Provides built-in functionality for common tasks
Goutte Pure PHP browser emulator Great for testing non-Javascript functionality
Installing Goutte
Behat + Goutte Config
Sample Mink Feature
Proof!
What About JavaScript?
PhantomJS
PhantomJS Headless browser based on WebKit Node app (don’t worry,
npm will save you)
Installing PhantomJS Good instructions at http://slid.es/gimler/behat-mink-phantomjs Install npm (Node Package
Manager) `npm install -g phantomjs`
Selenium2 + PHPUnit
Why Selenium2? PhantomJS can pretend to be a standalone Selenium2
server Configure Behat to send JavaScript scenarios to it
Behat + PhantomJS
Behat + PHPUnit Adds support for generic assertions
Adding in PHPUnit
Run PhantomJS `phantomjs --phantomjs --webdriver=8643`
Our first JS Scenario
Proof!
Now it gets grumpier
CSS Selectors Best way to locate specific elements on a
page If you disliked CSS before, this might push you over the edge
Y U MAD CHRIS? 'html body div.container div.row div.span9 section#modals
div#myModal.modal div.modal-header h3#myModalLabel' TOTALLY INTUITIVE Learn your browser debugger tools well
Pro Tip #1 Give all your elements ID’s Make it
easier for CSS selectors to find them
Waiting For JavaScript Behat steps will need wait() commands for
JS Gives time for browser to render Acceptance tests are not supposed to be fast
Pro Tip #2 Be conservative in your waiting estimates
Breaking down the steps
Breaking down the steps
Lessons Learned WAT is definitely “test-after” Learn CSS really well
or else Twitter Rage ensues Good ratio is 90% unit - 10% WAT
Lessons Learned Keep your feature files focused to scenario groups
Create app-critical scenarios
Advanced Level Different Behat configuration files for different environments `behat
---config <path to config file>`
Advanced Level Use Behat Gearman extension to run scenarios in
parallel http://extensions.behat.org/gearman/
