README

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 "app-verk/php-matcher"

Basic usage

Direct PHPMatcher usage

<?php

use AppVerk\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 AppVerk\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 AppVerk\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: ^2.3|^3.0|^4.0|^5.0 to be present
• @uuid@
• @ulid@
• @json@
• @string@||@integer@ - string OR integer
• @enum@ - used for PHP backend enums
• @tax_number@ - matches tax identification number(only PL format)
• @regon@ - matches registration number(only PL format)

Available pattern expanders

• startsWith($stringBeginning, $ignoreCase = false)
• endsWith($stringEnding, $ignoreCase = false)
• contains($string, $ignoreCase = false)
• notContains($string, $ignoreCase = false)
• isDateTime()
• isInDateFormat($format) - example "@datetime@.isInDateFormat('Y-m-d H:i:s')
• before(string $date) - example "@string@.isDateTime().before(\"2020-01-01 00:00:00\")"
• after(string $date) - example "@string@.isDateTime().after(\"2020-01-01 00:00:00\")"
• isTzOffset()
• isTzIdentifier()
• isTzAbbreviation()
• isEmail()
• isUrl()
• isIp()
• isEmpty()
• isNotEmpty()
• lowerThan($boundry)
• greaterThan($boundry)
• inArray($value) - example "@array@.inArray(\"ROLE_USER\")"
• 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()\"})"}
• isOneOf(class) - work's only with EnumMatcher, as argument it accepts class name with namespace e.g. @enum@.isOneOf('App\Domain\OrderStatus::class')

        "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@",

      }
      ,
      @...@
    ]
  }'
);

Xml matching

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

<?php

use AppVerk\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 AppVerk\PHPMatcher\PHPUnit\PHPMatcherAssertions trait, or extend the AppVerk\PHPMatcher\PHPUnit\PHPMatcherTestCase:

namespace AppVerk\PHPMatcher\Tests\PHPUnit;

use AppVerk\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');
