REST

Installation

If you use Codeception installed using composer, install this module with the following command:

composer require --dev codeception/module-rest

Alternatively, you can enable REST module in suite configuration file and run

codecept init upgrade4

This module was bundled with Codeception 2 and 3, but since version 4 it is necessary to install it separately.
Some modules are bundled with PHAR files.
Warning. Using PHAR file and composer in the same project can cause unexpected errors.

Description

Module for testing REST WebService.

This module requires either PhpBrowser or a framework module (e.g. Symfony, Laravel) to send the actual HTTP request.

Configuration

  • url optional - the url of api
  • shortDebugResponse optional - number of chars to limit the API response length

Example

modules:
   enabled:
       - REST:
           depends: PhpBrowser
           url: 'https://example.com/api/v1/'
           shortDebugResponse: 300 # only the first 300 characters of the response

In case you need to configure low-level HTTP headers, that’s done on the PhpBrowser level like so:

modules:
   enabled:
       - REST:
           depends: PhpBrowser
           url: &url 'https://example.com/api/v1/'
   config:
       PhpBrowser:
           url: *url
           headers:
               Content-Type: application/json

JSONPath

JSONPath is the equivalent to XPath, for querying JSON data structures. Here’s an Online JSONPath Expressions Tester

Public Properties

  • headers - array of headers going to be sent.
  • params - array of sent data
  • response - last response (string)

Parts

  • Json - actions for validating Json responses (no Xml responses)
  • Xml - actions for validating XML responses (no Json responses)

Conflicts

Conflicts with SOAP module

Actions

?>
  • param string $jsonPath
  • [Part] json

seeResponseJsonMatchesXpath

Checks if json structure in response matches the xpath provided. JSON is not supposed to be checked against XPath, yet it can be converted to xml and used with XPath. This assertion allows you to check the structure of response json. *

  { "store": {
      "book": [
        { "category": "reference",
          "author": "Nigel Rees",
          "title": "Sayings of the Century",
          "price": 8.95
        },
        { "category": "fiction",
          "author": "Evelyn Waugh",
          "title": "Sword of Honour",

        }
   ],

        "color": "red",
        "price": 19.95
      }
    }
  }
<?php
// at least one book in store has author
$I->seeResponseJsonMatchesXpath('//store/book/author');
// first book in store has author
$I->seeResponseJsonMatchesXpath('//store/book[1]/author');
// at least one item in store has price
$I->seeResponseJsonMatchesXpath('/store//price');
?>
  • param string $xpath
  • [Part] json

seeResponseMatchesJsonType

Checks that JSON matches provided types. In case you don’t know the actual values of JSON data returned you can match them by type. It starts the check with a root element. If JSON data is an array it will check all elements of it. You can specify the path in the json which should be checked with JsonPath

Basic example:

<?php
// {'user_id': 1, 'name': 'davert', 'is_active': false}
$I->seeResponseMatchesJsonType([
     'user_id' => 'integer',
     'name' => 'string|null',
     'is_active' => 'boolean'
]);

// narrow down matching with JsonPath:
// {"users": [{ "name": "davert"}, {"id": 1}]}
$I->seeResponseMatchesJsonType(['name' => 'string'], '$.users[0]');
?>

You can check if the record contains fields with the data types you expect. The list of possible data types:

  • string
  • integer
  • float
  • array (json object is array as well)
  • boolean
  • null

You can also use nested data type structures, and define multiple types for the same field:

<?php
// {'user_id': 1, 'name': 'davert', 'company': {'name': 'Codegyre'}}
$I->seeResponseMatchesJsonType([
     'user_id' => 'integer|string', // multiple types
     'company' => ['name' => 'string']
]);
?>

You can also apply filters to check values. Filter can be applied with a : char after the type declaration, or after another filter if you need more than one.

Here is the list of possible filters:

  • integer:>{val} - checks that integer is greater than {val} (works with float and string types too).
  • integer:<{val} - checks that integer is lower than {val} (works with float and string types too).
  • string:url - checks that value is valid url.
  • string:date - checks that value is date in JavaScript format: https://weblog.west-wind.com/posts/2014/Jan/06/JavaScript-JSON-Date-Parsing-and-real-Dates
  • string:email - checks that value is a valid email according to http://emailregex.com/
  • string:regex({val}) - checks that string matches a regex provided with {val}

This is how filters can be used:

<?php
// {'user_id': 1, 'email' => '[email protected]'}
$I->seeResponseMatchesJsonType([
     'user_id' => 'string:>0:<1000', // multiple filters can be used
     'email' => 'string:regex(~\@~)' // we just check that @ char is included
]);

// {'user_id': '1'}
$I->seeResponseMatchesJsonType([
     'user_id' => 'string:>0', // works with strings as well
]);
?>

You can also add custom filters by using {@link JsonType::addCustomFilter()}. See JsonType reference.
