REST

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

This module requires PHPBrowser or any of Framework modules enabled.

Example

modules:
   enabled:
       - REST:
           depends: PhpBrowser
           url: 'http://serviceapp/api/v1/'

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

seeResponseJsonMatchesJsonPath

Checks if json structure in response matches JsonPath. JsonPath is XPath equivalent for querying Json structures. Try your JsonPath expressions online. This assertion allows you to check the structure of response json.

// at least one item in store has price

?>

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. Starts check with a root element. If JSON data is array it will check the first element of an array. 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]');
?>

In this case you can match that record contains fields with data types you expected. The list of possible data types:

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

You can also use nested data type structures:

<?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 : char after the type declatation.

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' => 'davert@codeception.com'}
$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 y accessing JsonType::addCustomFilter method. See JsonType reference.
