Celtric Fixtures - PHP

Introduction

This is a small library that aims to offer an easy way to define static fixtures. By default it uses YAML files and a custom format (inspired by Alice format, which is also partially supported using AliceStyleParser included in this package), but tries to give several extension points so any developer can easily customize it.

What this library is not

The aim of this package is not to provide dynamic fixtures (via fake data generation). Support for it can be added, but you are encouraged to check out Alice or any other fixture generator.

An example

We are going to assume that we have the following class definition:

<?php

namespace Foo\Bar;

class Person
{
    private $name;
    private $age;

    public function __construct($name, $age)
    {
        $this->name = $name;
        $this->age = $age;
    }
}

And the following fixtures file: fixtures/people.yml

root_type: Foo\Bar\Person

ricard:
    name: Ricard
    age: 30

laura:
    name: Laura
    age: 29

We are now ready to use the library as follows:

<?php

namespace Tests;

class FooTest extends \PHPUnit_Framework_TestCase
{
    /** @test */
    public function can_load_fixtures()
    {
        $this->assertEquals(new Person("Ricard", 30), $this->fixture("people.ricard"));
    }
    
    /**
     * @param string $fixtureName
     * @return mixed
     */
    private function fixture($fixtureName)
    {
        $fixtures = Fixtures::celtricStyle(__DIR__ . "/../fixtures/");
        
        return $fixtures->fixture($fixtureName);
    }
}

A more complex example

We now have an slightly more complex class definition:

<?php

namespace Foo\Bar;

class Money
{
    private $amount;
    private $currency;

    public function __construct($amount, Currency $currency)
    {
        $this->amount = $amount;
        $this->currency = $currency;
    }
}

class Currency
{
    private $isoCode;

    public function __construct($isoCode)
    {
        $this->isoCode = $isoCode;
    }
}

In order to define fixtures for it, we can use the following example: fixtures/money.yml

root_type: Foo\Bar\Money

# We can inline the currency definition
two_euro:
    amount: 200
    currency<Foo\Bar\Currency>:
        isoCode: EUR

# Or we can reference it
three_euro:
    amount: 300
    currency: "@money.euro"

euro<Foo\Bar\Currency>:
    isoCode: EUR
