SchemaConformist

An automatic JSON request/response validator for testing in Rails

SchemaConformist is an automatic JSON request/response validator for your API testing in Rails.

This library automatically validates that JSON requests/responses are conformant with the schema. The schema can be described as one of JSON Hyper Schema, OpenAPI 2.0 and OpenAPI 3 (currently 3.0.2 is latest).

This library uses Committee to validate JSONs.

Add this line to your application's Gemfile:

gem 'schema_conformist'

and execute bundle install.

Configure schema_path as follows (ex. using an OpenAPI 3 schema):

Rails.application.config.schema_conformist.schema_path = Rails.root.join('doc', 'openapi.yaml')

That's all. Then all JSON requests/responses in integration-test/request-spec are validated according to your schema.

Write your API schema in one of JSON Hyper Schema, OpenAPI 2 and OpenAPI 3.

See test/dummy app for examples.

Configuration options are following:

• schema_conformist.schema_path
  • Required. The path where the schema is placed
• schema_conformist.ignored_api_paths
  • Optional. The array of API paths not to validate. Each path can be described in String literal (used for prefix search) or regular expression.
• schema_conformist.committee.old_assert_behavior
  • Optional. Set true if you want to skip validating request parameters. The default value is false.
  • cf. "Test Assertions" in Committee README
