DESCRIPTION

Provides methods on a Test::Mojo object suitable for using OpenAPI::Modern to validate the request and response.

ACCESSORS/METHODS

openapi

The OpenAPI::Modern object to use for validation. This object stores the OpenAPI schema used to describe requests and responses in your application, as well as the underlying JSON::Schema::Modern object used for the validation itself. See that documentation for information on how to customize your validation and provide the specification document.

If not provided, the object is constructed using configuration values passed to the application under the openapi key (see "new" in Test::Mojo), as for Mojolicious::Plugin::OpenAPI::Modern, or re-uses the object from the application itself if that plugin is applied.

request_valid

Passes $t->tx->req to "validate_request" in OpenAPI::Modern, as in "validate_request" in Mojolicious::Plugin::OpenAPI::Modern, producing a boolean test result.

request_not_valid, request_invalid

The inverse of "request_valid". May optionally take an error string, which is matched against the "recommended_response" in JSON::Schema::Modern::Result, and all error strings in the result.

response_valid

Passes $t->tx->res to "validate_response" in OpenAPI::Modern as in "validate_response" in Mojolicious::Plugin::OpenAPI::Modern, producing a boolean test result.

response_not_valid, response_invalid

The inverse of "response_valid". May optionally take an error string, which is matched against all error strings in the result.

Note that normally you shouldn't be testing for an invalid response, as all responses from your application should be valid according to the specification, but this method is provided for completeness. Instead, check for invalid responses right in your application (see Mojolicious::Plugin::OpenAPI::Modern) and log an error when this occurs.

operation_id_is

Test the operationId corresponding to the last validated request or response (the unique string used to identify the operation). See https://spec.openapis.org/oas/v3.1.0#operation-object.

request_validation_result

Returns the JSON::Schema::Modern::Result object for the validation result for the last request, or calculates it if not already available.

Does not emit a test result.

response_validation_result

Returns the JSON::Schema::Modern::Result object for the validation result for the last response, or calculates it if not already available.

Does not emit a test result.

FUTURE FEATURES

Lots of features are still to come, including:

  • request_invalid, response_invalid test methods, including a mechanism for providing the expected validation error(s)

  • stashing the validation results on the test object for reuse or diagnostic printing

  • integration with Mojolicious::Plugin::OpenAPI::Modern, including sharing the openapi object and customization options that are set in the application
