Magento Testing

• Unit Testing

– Tools

• Performance Testing

– Web page performance testing

– XHProf, Aoe_Profiler

• Resources

Unit Testing

• Available tools:

– plain phpunit

–MTAF

– EcomDev_PHPUnit

– TechDivision_MagentoUnitTesting

–Mage-Test

Plain phpunit

• Test API calls

• Test libraries

• Other basic tests

• Any other aspect of Magento that is

not dependent on things like session

• Requires lots of effort in “setUp()”

EcomDev_PHPUnit

• Integrated with Magento

• Supports Fixtures

• You can test pretty much any aspect

of Magento (Controllers, Models,

Layout, Config, etc)

Database settings

• app/etc/local.xml.phpunit

<phpunit>

<allow_same_db>?</allow_same_db>

</phpunit>

• 0

– Requires a separate db for the tests

• 1

– You can use the same db that Magento uses (local.xml)

Note: Fixtures will delete all existing records (@see ::apply() function in

Fixture/Processor/*)

Module Structure

#Namespace/Module/etc/config.xml <phpunit> <suite> <modules> <Namespace_Module /> </modules> </suite> </phpunit>

#Test files:Namespace/Module/Test/PathTo/Class.phpNamespace/Module/Test/fixtures/*.yamlNamespace/Module/Test/expectations/*.yamlNamespace/Module/Test/providers/*.yaml

Testing Emails

• Extend

Mage_Core_Model_Email_Template

• Mailcatcher.me (+API)

Mage_Core_Model_Email_Template

Mage::getConfig()->setNode(

'global/models/core/rewrite/email_template',

'Namespace_Test_Model_Email_Template'

);

// This is a hack to get the runtime config changes to take

effect

Mage::getModel('core/email_template');

$mailTemplate = Mage::getModel('core/email_template');

//… do your stuff

Note: https://github.com/MageTest/Mage-Test is the inspiration

for this approach

Mailcatcher configuration

$ gem install mailcatcher

$ mailcatcher

php.ini:

sendmail_path = /usr/bin/env catchmail -f mail@example.com

#REST API:

/messages

/messages/1.plain

/messages/1.json

Mailcatcher

CI Integration

• jenkins-php.org

• Book: Integrating PHP Projects with

Jenkins by Sebastian Bergmann

Examples

• Unit Test Demo

Functional Testing with CasperJS

“CasperJS is an open source navigation scripting & testing

utility”

• Writtern for PhantomJS or SlimerJS

• Good for “writing functional test suites,

saving results as JUnit XML”

• Other cool features: take screenshots, test

remote DOM, scrape web documents

‘No more CAPTCHAs, end robot

discrimination’

Why CasperJS

• Friendly

• Javascript

• Quick

• Simple

Performance testing

• Web Page

– webpagetest.org

– PageSpeed

– YSlow

– other tools

• Magento

• CI Integration

– webpagetest.org API

– PhantomJS + YSlow

PhantomCSS Tips

• Avoid dynamic data (homepage

menu, banners)

• Use version control for the base

pictures (and make sure you update

them when they should change)

• Use the same OS/browser/viewport
