## Usage
2538

26-
## Demo
39+
You can either use the `trait` or `class` version.
40+
41+
### Trait
42+
43+
<?php
44+
45+
namespace EnricoStahn\JsonAssert\Tests;
46+
47+
use EnricoStahn\JsonAssert\Assert as JsonAssert;
48+
49+
class MyTestCase extends \PHPUnit_Framework_TestCase
50+
{
51+
use JsonAssert;
52+
53+
public function testJsonDocumentIsValid()
54+
{
55+
// my-schema.json
56+
//
57+
// {
58+
// "type" : "object",
59+
// "properties" : {
60+
// "foo" : {
61+
// "type" : "integer"
62+
// }
63+
// },
64+
// "required" : [ "foo" ]
65+
// }
66+
67+
$json = json_decode('{"foo":1}');
68+
69+
$this->assertJsonMatchesSchemaString('./my-schema.json', $json);
70+
$this->assertJsonValueEquals(1, '* | [0]', $json);
71+
}
72+
}
73+
74+
### Class
75+
76+
In case you don't want to use the `trait` you can use the provided class wich extends from `\PHPUnit_Framework_TestCase`.
77+
You can either extend your test case or use the static methods like below.
78+
79+
<?php
80+
81+
namespace EnricoStahn\JsonAssert\Tests;
82+
83+
use EnricoStahn\JsonAssert\AssertClass as JsonAssert;
84+
85+
class MyTestCase extends \PHPUnit_Framework_TestCase
86+
{
87+
public function testJsonDocumentIsValid()
88+
{
89+
// my-schema.json
90+
//
91+
// {
92+
// "type" : "object",
93+
// "properties" : {
94+
// "foo" : {
95+
// "type" : "integer"
96+
// }
97+
// },
98+
// "required" : [ "foo" ]
99+
// }
100+
101+
$json = json_decode('{"foo":1}');
102+
103+
JsonAssert::assertJsonMatchesSchemaString('./my-schema.json', $json);
104+
JsonAssert::assertJsonValueEquals(1, '* | [0]', $json);
105+
}
106+
}
107+
108+
## Tests
109+
110+
To run the test suite, you need [composer](http://getcomposer.org).
111+
112+
$ composer install
113+
$ bin/phpunit
114+
115+
