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@
@time@
@date@
@datetime@
@timezone@ || @tz
@array@
@array_previous@ - match next array element using pattern from previous element
@array_previous_repeat@ - match all remaining array elements using pattern from previous element
@...@ - unbounded array, once used matcher will skip any further array elements
@null@
@*@ || @wildcard@
expr(expression) - optional, requires symfony/expression-language: ^6.4 || ^7.4 || ^8.0 to be present
@uuid@

Array Previous

@array_previous@ can also be used when matching JSON's and XML's

<?php

use Coduo\PHPMatcher\PHPMatcher;

$matcher = new PHPMatcher();

$matcher->match(
   array(
      'users' => array(
          array(
              'id' => 1,
              'firstName' => 'Norbert',
              'lastName' => 'Orzechowicz',
              'roles' => array('ROLE_USER'),

              'firstName' => 'Johnny',
              'lastName' => 'DąbrowsBravoki',
              'roles' => array('ROLE_HANDSOME_GUY')
          )
      ),
      true,
      6.66
  ),
   array(
      'users' => array(
          array(

$matcher = new PHPMatcher();

$matcher->match(
   array(
      'users' => array(

              'lastName' => 'Orzechowicz',
              'roles' => array('ROLE_USER'),
              'position' => 'Developer',
          ),
          array(
              'id' => 2,
              'firstName' => 'Michał',
              'lastName' => 'Dąbrowski',

              'id' => 3,
              'firstName' => 'Johnny',
              'lastName' => 'DąbrowsBravoki',
              'roles' => array('ROLE_HANDSOME_GUY')
          )
      ),
      true,
      6.66
  ),
   array(
      'users' => array(
          array(
              'id' => '@[email protected](0)',
              'firstName' => '@string@',
              'lastName' => 'Orzechowicz',
              'roles' => '@array@',
              'position' => '@[email protected]()'
          ),
          '@array_previous_repeat@'
      ),
      '@boolean@',
      '@double@'
  )
);

Json matching

<?php

use Coduo\PHPMatcher\PHPMatcher;

$matcher = new PHPMatcher();

$matcher->match(
  '{
    "users":[
      {
        "firstName": "Norbert",
        "lastName": "Orzechowicz",
        "created": "2014-01-01",
        "roles":["ROLE_USER", "ROLE_DEVELOPER"]
      }
    ]
  }',
  '{
    "users":[
      {
        "firstName": "@string@",
        "lastName": "@string@",
        "created": "@[email protected]()",
        "roles": "@array@",
        "position": "@[email protected]()"
      }
    ]
  }'
);

Json matching with unbounded arrays and objects

<?php

use Coduo\PHPMatcher\PHPMatcher;

$matcher = new PHPMatcher();

$matcher->match(
  '{
    "users":[
      {
        "firstName": "Norbert",
        "lastName": "Orzechowicz",
        "created": "2014-01-01",
        "roles":["ROLE_USER", "ROLE_DEVELOPER"],
        "attributes": {
          "isAdmin": false,
          "dateOfBirth": null,
          "hasEmailVerified": true
        },
        "avatar": {
          "url": "http://avatar-image.com/avatar.png"
        }
      },
      {
        "firstName": "Michał",
        "lastName": "Dąbrowski",
        "created": "2014-01-01",
        "roles":["ROLE_USER", "ROLE_DEVELOPER", "ROLE_ADMIN"],
        "attributes": {
          "isAdmin": true,
          "dateOfBirth": null,
          "hasEmailVerified": true
        },
        "avatar": null
      }
    ]
  }',
  '{
    "users":[
      {
        "firstName": "@string@",
        "lastName": "@string@",
        "created": "@[email protected]()",
        "roles": [
            "ROLE_USER",
            "@...@"
        ],
        "attributes": {

        },
        "avatar": "@[email protected]({\"url\":\"@[email protected]()\"})"
      }
      ,
      @...@
    ]
  }'
);

Xml matching

Optional - requires openlss/lib-array2xml: ^1.0 to be present.

<?php

use Coduo\PHPMatcher\PHPMatcher;

$matcher = new PHPMatcher();

$matcher->match(<<<XML
<?xml version="1.0"?>
<soap:Envelope
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

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');
