This package is considered both internal and experimental, and may change without notice.

Ibexa REST Test package

This package is part of Ibexa DXP.

To use this package, install Ibexa DXP.

Getting started

The purpose of the package is to provide Ibexa REST testing framework, reducing boilerplate code.

Installation

To start using it, install it together with ibexa/test-core:

composer req --dev ibexa/test-rest:^0.1.x-dev ibexa/test-core:^0.1.x-dev

Prerequisites

It is assumed that you already have created an instance of \Ibexa\Contracts\Core\Test\IbexaTestKernel and configured it via phpunit.integration.xml.dist or similar PHPUnit configuration file, together with your ./tests/integration/bootstrap.php.

Configuration

Register Bundles

Your custom IbexaTestKernel::registerBundles method needs to yield your bundle instance, and at least:

yield from parent::registerBundles();
yield new \Hautelook\TemplatedUriBundle\HautelookTemplatedUriBundle();
yield new \Ibexa\Bundle\Rest\IbexaRestBundle();
yield new \Ibexa\Bundle\Test\Rest\IbexaTestRestBundle();

Configure Container

Next, create REST routing configuration file, in a similar way project configuration file is prepared via recipes, e.g.: ./tests/integration/Resources/REST/routing/rest.yaml:

ibexa.acme.rest:
  resource: '@IbexaAcmeBundle/Resources/routing/rest.yaml'
  prefix: '%ibexa.rest.path_prefix%'

Then, in your custom IbexaTestKernel::registerContainerConfiguration method configure the following:

$loader->load(static function (ContainerBuilder $container): void {
    $container->loadFromExtension('framework', [
        'router' => [
            'resource' => __DIR__ . '/Resources/routing.yaml', // path to the file you've just created
        ],
    ]);
  
    $container->setParameter('form.type_extension.csrf.enabled', false);

    self::addSyntheticService($container, \Lexik\Bundle\JWTAuthenticationBundle\Services\JWTTokenManagerInterface::class);
});

Write your first test

At this point you should be able to write your first test:

use Ibexa\Contracts\Test\Rest\BaseRestWebTestCase;
use Ibexa\Contracts\Test\Rest\Request\Value\EndpointRequestDefinition;

final class GetAcmeTest extends BaseRestWebTestCase
{
    protected static function getEndpointsToTest(): iterable
    {
        $endpointRequestDefinition = new EndpointRequestDefinition(
            'GET',
            '/api/ibexa/v2/acme',
            'AcmeValue', // expected resource type
            self::generateMediaTypeString('AcmeValue', 'xml'), // accept header
            [], // custom HTTP headers to include in the request
            null, // InputPayload instance for POST/PATCH requests
            null, // custom request name for the data provider
            'acme/acme01' // snapshot name
        );

        yield $endpointRequestDefinition;

        yield $endpointRequestDefinition
            ->withAcceptHeader(self::generateMediaTypeString('AcmeValue', 'json'));
    }

    protected function getSchemaFileBasePath(string $resourceType, string $format): string
    {
        return dirname(__DIR__) . '/Resources/REST/Schemas/' . $resourceType;
    }

    protected static function getSnapshotDirectory(): ?string
    {
        return dirname(__DIR__) . '/Resources/REST/Snapshots';
    }
}

Base class

You need to override \Ibexa\Contracts\Test\Rest\BaseRestWebTestCase class.

Define what to test

The Test case class needs to override getEndpointsToTest static method which should yield EndpointRequestDefinition describing what endpoints and how you want to test.

Each EndpointRequestDefinition tests one endpoint, expecting one specific response format (XML or JSON).

EndpointRequestDefinition takes the following constructor arguments, in that order:

  • HTTP method type ('GET', 'POST', etc.)
  • Endpoint URI, including REST prefix.
  • Expected Resource Type the endpoint should return (e.g: 'Content', 'Product', or null for NoContent).
  • Accept HTTP header, e.g. application/vnd.ibexa.api.Content+xml (use self::generateMediaTypeString(resourceType, format) syntax sugar for that).
  • Extra HTTP headers if needed.
  • Input Payload (null for GET requests). See Testing endpoints requiring input payload for more details.
  • Endpoint request name used to generate PHPUnit data set name (null to use default name)
  • Snapshot name, see Testing snapshots for more details.

To test an endpoint in another format, you can use withAcceptHeader method which will clone the definition changing Accept header.

Response contents validation against schema files

REST Integration Test Framework, for each resource response, validates it against its schema (XSD or JSON).

Decide where you want to keep schema files and create a directory for them, e.g.: ./tests/integration/Resources/REST/Schemas. To configure it, your Test case class needs to define getSchemaFileBasePath method which returns schema file base path (including file name without an extension), e.g.: ./tests/integration/Resources/REST/Schemas/AcmeValue, where in Schemas directory, there are two schema files: AcmeValue.xsd and AcmeValue.json. You can generate these schema files using IDE and/or some online tools.

Typically, you'd want to create your own abstract base class defining this and make each Test case class extend it instead, e.g.:

abstract class BaseAcmeRestWebTestCase extends BaseRestWebTestCase
{
    protected function getSchemaFileBasePath(string $resourceType, string $format): string
    {
        return dirname(__DIR__) . '/Resources/REST/Schemas/' . $resourceType;
    }
}

File extension is not included because it depends on a validator (e.g. XSD for XML files).

Testing snapshots

If you have a response snapshot to test against, your Test case class needs to override getSnapshotDirectory method and define snapshot base file path (without extension) when instantiating EndpointRequestDefinition.

REST Test Framework looks for a snapshot file concatenating:

<snapshot_directory>/<snapshot_name>.<response_format:json|xml>

If you want to generate a snapshot at runtime, set the following environment variable:

TEST_REST_GENERATE_SNAPSHOTS=1

Testing endpoints requiring input payload

To test mutation endpoints (POST, PATCH, PUT, etc.) you need to create input payload files and load them using \Ibexa\Contracts\Test\Rest\Input\PayloadLoader while creating EndpointRequestDefinition.

Example:

    public static function getEndpointsToTest(): iterable
    {
        $payloadLoader = new PayloadLoader(dirname(__DIR__) . '/Resources/REST/InputPayloads');

        yield new EndpointRequestDefinition(
            'POST',
            '/api/ibexa/v2/acme',
            'AcmeValue',
            self::generateMediaTypeString('AcmeValue', 'xml'),
            [],
            $payloadLoader->loadPayload('AcmeValueCreate', 'xml', 'Acme/CustomPayloadFileName')
        );

        yield new EndpointRequestDefinition(
            'POST',
            '/api/ibexa/v2/acme',
            'AcmeValue',
            self::generateMediaTypeString('AcmeValue', 'json'),
            [],
            $payloadLoader->loadPayload('AcmeValueCreate', 'json', 'Acme/CustomPayloadFileName')
        );
    }

PayloadLoader::loadPayload expects 2 arguments: input Media Type, format. Optionally you can pass custom file base path (without extension) as the 3rd argument. If not given, the file base path will default to the given Media Type.
