data-provider

This project provides a composer package with generic data providers for use with phpunit/phpunit.

Installation

Run

composer require ergebnis/data-provider

Usage

This package provides the following generic data providers:

• Ergebnis\DataProvider\BoolProvider
• Ergebnis\DataProvider\FloatProvider
• Ergebnis\DataProvider\IntProvider
• Ergebnis\DataProvider\NullProvider
• Ergebnis\DataProvider\ObjectProvider
• Ergebnis\DataProvider\ResourceProvider
• Ergebnis\DataProvider\StringProvider
• Ergebnis\DataProvider\UuidProvider

Since it is possible to use multiple @dataProvider annotations or PHPUnit\Framework\Attribute\DataProviderExternal attributes for test methods, these generic data providers allow for reuse and composition of data providers:

<?php

declare(strict_types=1);

namespace Example\Test;

use Ergebnis\DataProvider;
use PHPUnit\Framework;

final class ExampleTest extends Framework\TestCase
{
    /**
     * @dataProvider \Ergebnis\DataProvider\StringProvider::blank()
     * @dataProvider \Ergebnis\DataProvider\StringProvider::empty()
     */
    public function testFromNameRejectsInvalidValueWithAnnotation(string $value): void
    {
        $this->expectException(\InvalidArgumentException::class);
        $this->expectExceptionMessage('Value can not be an empty or blank string.');

        UserName::fromString($value);
    }

    #[Framework\DataProviderExternal(DataProvider\StringProvider::class, 'blank')]
    #[Framework\DataProviderExternal(DataProvider\StringProvider::class, 'empty')]
    public function testFromNameRejectsInvalidValueWithAttribute(string $value): void
    {
        $this->expectException(\InvalidArgumentException::class);
        $this->expectExceptionMessage('Value can not be an empty or blank string.');

        UserName::fromString($value);
    }
}
