PHP Matcher

Library created for testing all kinds of JSON/XML/TXT/Scalar values against patterns.

API:

PHPMatcher::match($value = '{"foo": "bar"}', $pattern = '{"foo": "@string@"}') : bool;
PHPMatcher::backtrace() : Backtrace;
PHPMatcher::error() : ?string;

It was built to simplify API's functional testing.

Installation

Require new dev dependency using composer:

composer require --dev "coduo/php-matcher"

Basic usage

Direct PHPMatcher usage

<?php

use Coduo\PHPMatcher\PHPMatcher;

$matcher = new PHPMatcher();
$match = $matcher->match("lorem ipsum dolor", "@string@");

if (!$match) {
    echo "Error: " . $matcher->error();
    echo "Backtrace: \n";
    echo (string) $matcher->backtrace();
}

PHPUnit extending PHPMatcherTestCase

<?php

use Coduo\PHPMatcher\PHPUnit\PHPMatcherTestCase;

class MatcherTest extends PHPMatcherTestCase
{
    public function test_matcher_that_value_matches_pattern()
    {
        $this->assertMatchesPattern('{"name": "@string@"}', '{"name": "Norbert"}');
    }
}

PHPUnit using PHPMatcherAssertions trait

<?php

use Coduo\PHPMatcher\PHPUnit\PHPMatcherAssertions;
use PHPUnit\Framework\TestCase;

class MatcherTest extends TestCase
{
    use PHPMatcherAssertions;

    public function test_matcher_that_value_matches_pattern()
    {
        $this->assertMatchesPattern('{"name": "@string@"}', '{"name": "Norbert"}');
    }
}

Available patterns

@string@
@integer@
@number@
@double@
@boolean@
@array@
@...@ - unbounded array
@null@
@*@ || @wildcard@
expr(expression)
@uuid@
@json@
@string@||@integer@ - string OR integer

Available pattern expanders

startsWith($stringBeginning, $ignoreCase = false)
endsWith($stringEnding, $ignoreCase = false)
contains($string, $ignoreCase = false)
notContains($string, $ignoreCase = false)
isDateTime()
isEmail()
isUrl()
isIp()
isEmpty()
isNotEmpty()
lowerThan($boundry)
greaterThan($boundry)
inArray($value)
hasProperty($propertyName) - example "@json@.hasProperty(\"property_name\")"
oneOf(...$expanders) - example "@string@.oneOf(contains('foo'), contains('bar'), contains('baz'))"
matchRegex($regex) - example "@string@.matchRegex('/^lorem.+/')"
optional() - work's only with ArrayMatcher, JsonMatcher and XmlMatcher
count() - work's only with ArrayMatcher - example "@array@.count(5)"
repeat($pattern, $isStrict = true) - example '@array@.repeat({"name": "foe"})' or "@array@.repeat('@string@')"
match($pattern) - example {"image":"@json@.match({\"url\":\"@string@.isUrl()\"})"}

Example scenario for api in behat using mongo.

@profile, @user
Feature: Listing user toys

  As a user
  I want to list my toys

  Background:
    Given I send and accept JSON

  Scenario: Listing toys
    Given the following users exist:
      | firstName     | lastName     |
      | Chuck         | Norris       |

    And the following toys user "Chuck Norris" exist:
      | name            |
      | Barbie          |
      | GI Joe          |
      | Optimus Prime   |

    When I set valid authorization code oauth header for user "Chuck Norris"
    And I send a GET request on "/api/toys"
    Then the response status code should be 200
    And the JSON response should match:
    """
      [
        {
          "id": "@string@",
          "name": "Barbie",
          "_links: "@*@"
        },
        {
          "id": "@string@",
          "name": "GI Joe",
          "_links": "@*@"
        },
        {
          "id": "@string@",
          "name": "Optimus Prime",
          "_links": "@*@"
        }
      ]
    """

PHPUnit integration

The assertMatchesPattern() is a handy assertion that matches values in PHPUnit tests. To use it either include the Coduo\PHPMatcher\PHPUnit\PHPMatcherAssertions trait, or extend the Coduo\PHPMatcher\PHPUnit\PHPMatcherTestCase:

namespace Coduo\PHPMatcher\Tests\PHPUnit;

use Coduo\PHPMatcher\PHPUnit\PHPMatcherAssertions;
use PHPUnit\Framework\TestCase;

class PHPMatcherAssertionsTest extends TestCase
{
    use PHPMatcherAssertions;

    public function test_it_asserts_if_a_value_matches_the_pattern()
    {
        $this->assertMatchesPattern('@string@', 'foo');
    }
}

The matchesPattern() method can be used in PHPUnit stubs or mocks:

$mock = $this->createMock(Foo::class);
$mock->method('bar')
    ->with($this->matchesPattern('@string@'))
    ->willReturn('foo');
