openapi-validator-bundle

An OpenAPI specification validator for a symfony application

It checks if the request and response from your symfony application matches your openapi documentation file.
If the endpoint is not documented, receives or responds with mismatching payload it will throw ValidationError.
This comes in handy when application has integration/functional/manual tests because it will alert early that documentation is outdated.

Installation

composer require temirkhann/openapi-validator-bundle

Usage

Enable bundle in config/bundles.php

// Usually you don't want validation to work on your production server.  
// So, enable it for all envs and disable for prod
return [
    Symfony\Bundle\FrameworkBundle\FrameworkBundle::class => ['test' => true],
    ....
    TemirkhanN\OpenapiValidatorBundle\OpenapiValidatorBundle::class => ['all' => true, 'prod' => false],
];

Declare configuration in config/packages/openapi_validator.yaml as follows:

openapi_validator:
  # Path to your openapi specification (json or yaml)
  # Only local file is accepted (http links won't work)
  specification: '%kernel.project_dir%/openapi.yaml'

Configuration

If you have multiple sections in your application or for some reason don't want to apply validation to some particular
endpoints you can use exclusion policy

openapi_validator:
  specification: '%kernel.project_dir%/openapi.yaml'
  policy:
    exclude:
      paths:
        - '#^/some-internal/#'
      status_codes:
        - 304
        - 500

paths accepts list of regexp patterns. If the request path(not URI) matches pattern then validation will be omitted.

defaults value is empty list - validation is applied to every single route.

status_codes accepts list of integer values which represent http status-codes. If response code matches any of these
then validation will be omitted.

default value is 500. There should never be 500 in API documentation.
