[back to package description]

swagger-test

This is a tool for Property Based Testing of swagger APIs.

It basically allow you to approximate the computation of the following proposition:

![](https://latex.codecogs.com/png.latex?\forall&space;\,&space;input&space;\in&space;\text{API}&space;\,&space;:&space;\underset{API}{valid}(input)&space;\Rightarrow&space;\underset{API}{valid}(output)&space;\\&space;\text{where}&space;\\&space;output&space;=&space;\underset{API}{request}(input))

Which translates to:

For all valid requests that can be derived from my Swagger schema, the API response obtained from executing that request is valid according to the same Swagger schema.

The tool exposes several ways to configure get value from parts of it, for example, you may be interested in getting just a random valid request from the schema (use the generate command), or validating if a given response (from a particular operation) is valid (use the validate command), or, run one sample instance of the full proposition, which picks a random request and validate it's resulting response (use the request command).

The generator random request values are reproducible by re-using the same seed value, or one can focus on a particular operation by specifying the operation id.

The tool also simplifies integration with other systems by allowing to configure output formats as standard HTTP message, JSON, or curl. Additionally, there are Haskell modules exposed as a library if one wants to build on top of it.

Command Line Interface

swagger-test supports three commands:

  • generate - generates a new random valid request from Swagger schema.
  • validate - validate a response to a given operation id, according to the schema.
  • request - generate and make the request, then validates the response (combines generate and validate).
  • report - high-level command that run several requests concurrently, and write HTML reports for multiple Swagger schemas. Useful for testing systems with many Swagger services in a CI server.
