Extension for PhpUnit, that helps you to test JSON or Array with changeable values, like timestamps, count etc. It can be very helpful if you decide to test your API. All you need - is to define data structure with set of helper classes.
via composer
composer require zlob/any-json-tester
Lets test JSON like
{
"id" : "1",
"author" : "Zlob",
"project" : "AnyJsonTester",
"date" : "21-09-2015",
"rating" : "9.9",
"url" : "https://github.com/Zlob/AnyJsonTester",
"comments" : [
{
"text" : "awesome",
"like" : "true"
},
{
"text" : "Very good",
"like" : "true"
}
]
}'Test code:
<?php
//import classes
use AnyJsonTester\Types\AnyArray;
use AnyJsonTester\Types\AnyBoolean;
use AnyJsonTester\Types\AnyDateTime;
use AnyJsonTester\Types\AnyFloat;
use AnyJsonTester\Types\AnyInteger;
use AnyJsonTester\Types\AnyObject;
use AnyJsonTester\Types\AnyString;
class ExampleTest extends PHPUnit_Framework_TestCase
{
//use AnyJsonTester trait
use \AnyJsonTester\AnyJsonTester;
public function testSeeJsonLikeSimple()
{
//JSON, that we wont to test
$JSON = '{
"id" : "1",
"author" : "Zlob",
"project" : "AnyJsonTester",
"date" : "21-09-2015",
"rating" : "9.9",
"url" : "https://github.com/Zlob/AnyJsonTester",
"comments" : [
{
"text" : "awesome",
"like" : "true"
},
{
"text" : "Very good",
"like" : "true"
}
]
}';
//describe JSON schema
$expectedJson = new AnyObject([
'id' => new AnyInteger(), // you can set restrictions for type, like min, max
'author' => new AnyString(), // string length or regex
'date' => new AnyDateTime(), // date period or format
'rating' => new AnyFloat(), // precision
'project' => 'AnyJsonTester', // or you can just set explicit value
// or skip some fields, that you don`t wont to test
'comments' => new AnyArray(new AnyObject( //you can test array of objects, set min and max array length
[
'text' => new AnyString(),
'like' => new AnyBoolean() //test boolean variables
]
)
)
]
);
//call seeJsonLike function to test JSON against schema
static::seeJsonLike($JSON, $expectedJson, false);
}
}After install, use AnyJsonTester trait in your test class. It gives you two methods: seeJsonLike to test JSON, and seeArrayLike to test arrays.
In my favorite framework, you can use AnyJsonTesterLaravel trait instead of AnyJsonTester trait, that will automatically retrieves data from response, so you can chain seeJsonLike method with request method, like
$this->post('/user', ['name' => 'Sally'])
->seeJsonLike( new AnyObject( [ 'name' => AnyJsonString() ] ) );##Interface Trait has only two public methods: seeJsonLike and seeArrayLike, that takes as argument AnyObject or AnyArray object (and tested JSON string in case of non-Laravel trait). AnyObject is used to test JSON object like '{"name" : "Zlob"}' and can use additional types described bellow. AnyArray is used to test JSON array of similar objects, such as AnyObject, AnyInteger and etc. or even another AnyArray. ##Supported types ####AnyObject - help to test JSON objects #####Arguments:
- options - array, avaible options are:
- hasFields - array of fields and values, that Object should contain. Instead of explicit value, you may use one of supportd types
- hasNoFields - array of fields, that Object should not contain.
- strictMode - boolean. In strict mode, object can contain only fields, described in hasFields option
- nullable - boolean. If true, object can be null.
#####Example:
$anyObject = new AnyObject(
[
'hasFields' => ['id' => '1', 'name' => new AnyString()],
'hasNoFields' => ['password'],
'strictMode' => true,
'nullable' => false
]
);####AnyArray - helps to test array #####Arguments:
- expectedElement - AnyObject, AnyBoolean, AnyDateTime, AnyFloat, AnyInteger, AnyString or another AnyArray object, that describe content of array items
- options - array, avaible options are:
- min - int, minimum array length
- max - int, maximum array length
- nullable - boolean. If true, array can be null.
#####Example:
$anyArray = new AnyArray(
new AnyObject(['name' => 'Zlob']),
[
'min' => 1,
'max' => 100,
'nullable' => true
]
);####AnyString - helps to test strings #####Arguments:
- options - array, avaible options are:
- min - int, minimum string length
- max - int, maximum string length
- regex - string, regex pattern
- enum - array, defines possible string values
- nullable - boolean. If true, string can be null.
#####Example:
$anyString = new AnyString(
[
'min' => 1,
'max' => 20,
'regex' => '/rin/',
'enum' => ['value 1', 'value 2'],
'nullable' => true
]
);####AnyInteger - helps to test integers #####Arguments:
- options - array, avaible options are:
- min - int, minimum integer value
- max - int, maximum integer value
- nullable - boolean. If true, integer can be null.
#####Example:
$anyInteger = new AnyInteger(
[
'min' => 1,
'max' => 2000,
'nullable' => true
]
);####AnyFloat - helps to test floats #####Arguments:
- options - array, avaible options are:
- min - int, minimum float value
- max - int, maximum float value
- precision - int, float precision
- nullable - boolean. If true, float can be null.
#####Example:
$anyFloat = new AnyFloat(
[
'min' => 1,
'max' => 99.99,
'precision' => 2
'nullable' => true
]
);####AnyDateTime - helps to test date and time #####Arguments:
- options - array, avaible options are:
- min - int, minimum date/time value
- max - int, maximum date/time value
- format - string, DateTime format
- nullable - boolean. If true, value can be null.
#####Example:
$anyDateTime = new AnyDateTime(
[
'min' => '14-12-1987 23:57',
'max' => '22-09-2015 14:30',
'format' => 'd-m-Y H:i'
'nullable' => true
]
);####AnyBoolean - helps to test boolean #####Arguments:
- options - array, avaible options are:
- strictMode - bool, if true - only 'true' and 'false' strings are boolean. Otherwise, 'true', 'false', '0', '1', 'on', 'off', 'yes' and 'no'.
- nullable - boolean. If true, value can be null.
#####Example:
$anyBoolean = new AnyBoolean(
[
'strictMode' => false,
'nullable' => true
]
