About

OpenAPI Spec Validator is a Python library that validates OpenAPI Specs against the OpenAPI 2.0 (aka Swagger) and OpenAPI 3.0 specification. The validator aims to check for full compliance with the Specification.

Installation

$ pip install openapi-spec-validator

Alternatively you can download the code and install from the repository:

$ pip install -e git+https://github.com/p1c2u/openapi-spec-validator.git#egg=openapi_spec_validator

Usage

Command Line Interface

Straight forward way:

$ openapi-spec-validator openapi.yaml

pipes way:

$ cat openapi.yaml | openapi-spec-validator -

docker way:

$ docker run -v path/to/openapi.yaml:/openapi.yaml --rm p1c2u/openapi-spec-validator /openapi.yaml

or more pythonic way:

$ python -m openapi_spec_validator openapi.yaml

Examples

Validate spec:

from openapi_spec_validator import validate_spec
from openapi_spec_validator.readers import read_from_filename

spec_dict, spec_url = read_from_filename('openapi.yaml')

# If no exception is raised by validate_spec(), the spec is valid.
validate_spec(spec_dict)

validate_spec({})

Traceback (most recent call last):
    ...
OpenAPIValidationError: 'openapi' is a required property

Add spec_url to validate spec with relative files:

validate_spec(spec_dict, spec_url='file:///path/to/spec/openapi.yaml')

You can also validate spec from url:

from openapi_spec_validator import validate_spec_url

# If no exception is raised by validate_spec_url(), the spec is valid.
validate_spec_url('http://example.com/openapi.json')

If you want to iterate through validation errors:

from openapi_spec_validator import openapi_v3_spec_validator

errors_iterator = openapi_v3_spec_validator.iter_errors(spec)
