ApiTestCase
===========
[](https://scrutinizer-ci.com/g/lchrusciel/ApiTestCase/?branch=master)
**ApiTestCase** is a PHPUnit TestCase that will make your life as a Symfony API developer much easier. It extends basic [Symfony](https://symfony.com/) WebTestCase with some cool features.
Thanks to [PHP-Matcher](https://github.com/coduo/php-matcher) you can, according to its readme, "write expected json responses like a gangster". We definitely agree.
It also uses [Alice](https://github.com/nelmio/alice) for easy Doctrine fixtures loading.
Features:
* Clear TDD workflow for API development with Symfony;
* JSON/XML matching with clear error messages;
* Fixtures loading with Alice *(optional)*;
Installation
------------
Assuming you already have Composer installed globally:
```bash
composer require --dev lchrusciel/api-test-case
```
And it's done! ApiTestCase is working with the default configuration.
Usage
-----
We provide two base classes for your test cases: JsonApiTestCase and the XmlApiTestCase. Choose one based on the format of the API you want to create.
### Json Example
The basic TDD workflow is the following:
1. Write a test case that sends the request and use ``assertResponse`` assertion method to check if response contents are matching your expectations. You need a name for the response file;
2. Create the file with name that you picked in step 1. and put expected response contents there. It should be put in ``src/AppBundle/Tests/Responses/Expected/hello_world.json`` for example.
3. Make it red.
4. Make it green.
5. Refactor.
Let's see a simple example! Write the following test:
```php
namespace AppBundle\Tests\Controller\HelloWorldTest;
use ApiTestCase\JsonApiTestCase;
class HelloWorldTest extends JsonApiTestCase
{
public function testGetHelloWorldResponse()
{
$this->client->request('GET', '/');
$response = $this->client->getResponse();
$this->assertResponse($response, 'hello_world');
}
}
```
Now define the expected response file:
```json
{
"message": "Hello ApiTestCase World!"
}
```
Run your tests:
```bash
vendor/bin/phpunit
```
Your test should fail with some errors, you are probably missing the controller and routing, so go ahead and define them!
As soon as you implement your Controller and configure appropriate routing, you can run your tests again:
If the response contents will match our expectations, console will present a simple message:
```bash
OK (1 tests, 2 assertions)
```
Otherwise it will present diff of received messages:
```bash
"Hello ApiTestCase World" does not match "Hello ApiTestCase World!".
@@ -1,4 +1,3 @@
{
- "message": "Hello ApiTestCase World!"
+ "message": "Hello ApiTestCase World"
}
-
```
Firstly, function `assertResponse` will check the response code (200 is a default response code), then it will check if header of response contains `application/json` content type. At the end it will check if the response contents matches the expectation.
Sometimes you can't predict some values in the response, for example autogenerated date or id from the database. No magic is needed here because [PHP-Matcher](https://github.com/coduo/php-matcher) comes with a helping hand. These are just a few examples of available patterns:
* ``@string@``
* ``@integer@``
* ``@boolean@``
* ``@array@``
Check for more on [PHP-Matcher's documentation](https://github.com/coduo/php-matcher).
With these patterns your expected response will look like this:
```json
{
"message": "@string@"
}
```
With this in place, any string under key `message` will match the pattern. More complicated expected response could look like this:
```json
[
{
"id": "@integer@",
"name": "Star-Wars T-shirt",
"sku": "SWTS",
"price": 5500,
"sizes": "@array@",
"created_at": "@[email protected]()"
},
{
"id": "@integer@",
"name": "Han Solo Mug",
"sku": "HSM",
"price": 500,
"sizes": "@array@",
"created_at": "@[email protected]()"
}
]
```
And will match the following list of products:
```php
array(
array(
'id' => 1,
'name' => 'Star-Wars T-shirt',
'sku' => 'SWTS',
'price' => 5500,
'sizes' => array('S', 'M', 'L'),
'created_at' => new \DateTime(),
),
array(
'id' => 2,
'name' => 'Han Solo Mug',
'sku' => 'HSM',
'price' => 500,
'sizes' => array('S', 'L'),
'created_at' => new \DateTime(),
),
)
```
### Testing With Database Fixtures
ApiTestCase is integrated with ``nelmio/alice``. Thanks to this nice library you can easily load your fixtures when you need them. You have to define your fixtures and place them in an appropriate directory.
Here is some example how to define your fixtures and use case. For more information how to define your fixtures check [Alice's documentation](https://github.com/nelmio/alice).
In order to use Alice with Doctrine, you should enable two additional bundles:
**Symfony 4.0+**
```php
// config/bundles.php
return [
// ...
Nelmio\Alice\Bridge\Symfony\NelmioAliceBundle::class => ['test' => true],
Fidry\AliceDataFixtures\Bridge\Symfony\FidryAliceDataFixturesBundle::class => ['test' => true],
];
```
Now, let's say you have a mapped Doctrine entity called Book in your application:
```php
class Book
{
private $id;
private $title;
private $author;
// ...
}
```
To load fixtures for the test, you need to define a simple ``YAML`` file in ``src/AppBundle/Tests/DataFixtures/ORM/books.yml``:
```yml
ApiTestCase\Test\Entity\Book:
book1:
title: "Lord of The Rings"
author: "J. R. R. Tolkien"
book2:
title: "Game of Thrones"
price: "George R. R. Martin"
```
Finally, to use these fixtures in a test, just call a proper method:
```php
public function testBooksIndexAction()
{
// This method require subpath to locate specific fixture file in your DataFixtures/ORM directory.
$this->loadFixturesFromFile('books.yml');
// There is another method that allows you to load fixtures from directory.
$this->loadFixturesFromDirectory('big_library');
}
```
Configuration Reference
-----------------------
To customize your test suite configuration you can add a few more options to phpunit.xml:
```xml
```
* `KERNEL_CLASS` allows you to specify exactly which class should be used in order to setup the Kernel.
* `ERESPONSE_DIR` variable contain paths to folder with expected responses. It is used when API result is compared with existing json file. If this value isn't set, ApiTestCase will try to guess location of responses, looking for the responses in a folder: '../Responses' relatively located to your controller test class.
* `FIXTURES_DIR` variable contains a path to folder with your data fixtures. By default if this variable isn't set it will search for `../DataFixtures/ORM/` relatively located to your test class . ApiTestCase throws RunTimeException if folder doesn't exist or there won't be any files to load.
* `OPEN_ERROR_IN_BROWSER` is a flag which turns on displaying error in a browser window. The default value is false.
* `OPEN_BROWSER_COMMAND` is a command which will be used to open browser with an exception.
* `IS_DOCTRINE_ORM_SUPPORTED` is a flag which turns on doctrine support includes handy data fixtures loader and database purger.
* `TMP_DIR` variable contains a path to temporary folder, where the log files will be stored.
* `ESCAPE_JSON` is a flag which turns on escaping (unicode characters and slashes) of your JSON output before comparing it to expected data. The default value is false. This flag only exists for backwards compatibility with previous versions of ApiTestCase (when turned on) and will be removed in a future version.
