data-provider

Installation

Run

composer require --dev 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

Since it is possible to use multiple @dataProvider annotations for test methods, these generic data providers allow for reuse and composition of data providers:

<?php

declare(strict_types=1);

namespace Example\Test;

use PHPUnit\Framework;

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

        UserName::fromString($value);
    }
}

• greaterThanZero() provides ints greater than 0.0
• lessThanOne() provides ints less than 1.0
• lessThanZero() provides ints less than 0.0
• one() provides 1.0
• zero() provides 0.0

For examples, see Ergebnis\DataProvider\Test\Unit\FloatProviderTest.

DataProvider\IntProvider

• arbitrary() provides arbitrary ints
