swagger2yaml — Convert Swagger specs into Taurus YAML

Taurus includes a command-line utility named swagger2yaml that can be used to convert existing Swagger definitions into Taurus YAML-based configs.

Supported command-line options:

  • -h, --help - show help message and exit
  • -q, --quiet - only errors printed to console
  • -v, --verbose - prints all logging messages to console
  • -j, --json - use json format instead of yaml
  • -o FILE_NAME, --out=FILE_NAME - change output file name, by default is input file name + .yml in current directory
  • --scenarios-from-paths - generate a scenario per Swagger path (instead of generating a single scenario). disabled by default.
  • --parameter-interpolation - setup interpolation for templated parameters. Valid values are 'values', 'variables', 'none'. Default is 'values'.


  • swagger2yaml swagger.json - convert Swagger spec
  • swagger2yaml swagger.json -o swagger-converted.yml --scenarios-from-paths - convert Swagger spec, creating a scenario per path, and save it to a specific file

Notes about Swagger to YAML translation process:

  1. The whole spec can be converted either into a single scenario or to multiple scenarios (--scenarios-from-paths)
  2. Templated paths (e.g. /api/users/{userId}) are converted to real paths by replacing path parameters with placeholder values according to parameter type
  3. All types of parameters (except for body) are supported: path, query, header, formData.
  4. While swagger2yaml can generate dummy data for parameters using type and format fields, the generation of dummy data from schema field (containing JSON Schema definition) isn't supported (yet).
  5. Some authentication types are not supported yet
