Awesome Team

Awesome Challenges

Why Testing?Why should I test my code ?

Reduce False assumptions -> If you rely on assumptions it will surely fail…

Validate that there is no regression

Make sure the code runs as expected

Test limit values (security,big data)

Automate repetitive tasks -> Good developers are lazy developers!!!

It makes debugging/correction so much easier

But…

Often developers finds it hard to write

Too long too run

Doesn’t correspond to business logic/behaviour/user scenario

CodeCeption(1)http://codeception.com/ (English)

Test Framework

Acceptance Tests

Functional Tests

Unit Tests

Easy

To read

To write

To debug

Natively handles PHPUnit -> standard

http://codeception.com/

CodeCeption(2)BDD-style scenario-driver tests

WebServices tests (SOAP/REST/XML-RPC)

Generates reports(HTML/XML/JSON)

Laravel/Zend/Phalcon/Yii2/Symfony/Composer modules -> No excuse!

Integration with continuous deployment (Jenkins/Bamboo)

Can be used along with Selenium2 and PhantomJS for advanced tests

What does it look like?<?php $I = new AcceptanceTester($scenario); $I->wantTo('create wiki page'); $I->amOnPage('/'); $I->click('Pages'); $I->click('New'); $I->see('New Page'); $I->fillField('title', 'Hobbit'); $I->fillField('body', 'By Peter Jackson'); $I->click('Save'); $I->see('page created'); // notice generated $I->see('Hobbit','h1'); // head of page of is our title $I->seeInCurrentUrl('pages/hobbit'); $I->seeInDatabase('pages', array('title' => ‘Hobbit')); ?>

Function Testing

Acceptance Tests

Enable to do request and interact with the DOM

Use a fake browser to perform the queries

Can click and fill forms

Can be plugged with Selenium/PhantomJS to interact with JavaScript and screenshots

Slowest tests to run

Functional TestsSame as Acceptance test but does not use a browser

engine

Can be plugged with the framework to access internal functions and properties (Models, validation)

Use $_REQUEST, $_POST and $_GET

Faster

No DOM interaction (JS/Ajax/Events)

Unit TestsUsed to test functions Can be plugged with the framework to access internal functions and properties (Models, Validation) Fastest Difficult to use in MVC Not readable by Humans

public function testValidation() { $user = User::create(); $user->username = null; $this->assertFalse($user->validate(['username'])); $user->username = 'toolooooongnaaaaaaameeee'; $this->assertFalse($user->validate(['username'])); $user->username = 'davert'; $this->assertTrue($user->validate(['username'])); }

Let’s get the party started>codecept run

>codecept run —debug

Bonus

>codecept generate:scenarios acceptance //English version

>codecept console acceptance //Interactive console

>codecept run —debug —env test

Demo Time !!!!!> Let’s test PHP conference Kansai website !

Best practices1. Run tests on your vagrant -> GIT push ONLY when tests pass

2. Deploy on test server -> Validate tests on test server

3. Deploy on production ONLY if tests pass on test server

4. NEVER run on production ! NEVER!!!

1. It creates new entries and change Database

2. Add load on the production server

3. Need new set of tests/monitoring on production
