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 can be used either with frameworks or PHPBrowser. If a framework module is connected, the testing will occur in the application directly. Otherwise, a PHPBrowser should be specified as a dependency to send requests and receive responses from a server.

Configuration

url optional - the url of api
shortDebugResponse optional - amount of chars to limit the api response length

This module requires PHPBrowser or any of Framework modules enabled.

In case you need to configure low-level HTTP fields, that’s done on the PHPBrowser level. Check the example below for details.

Example

modules:
   enabled:
       - REST:
           depends: PhpBrowser
           url: &url 'http://serviceapp/api/v1/' # you only need the &url anchor for further PhpBrowser configs
           shortDebugResponse: 300 # only the first 300 chars of the response
   config:
       PhpBrowser:
           url: *url # repeats the URL from the REST module; not needed if you don't have further settings like below
           headers:
               Content-Type: application/json

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

amAWSAuthenticated

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.
