Generate test data from JSON schemata with Hypothesis

Project description

hypothesis-jsonschema

A Hypothesis strategy for generating data that matches some JSON schema.

Here's the PyPI page.

API

The public API consists of just one function: hypothesis_jsonschema.from_schema, which takes a JSON schema and returns a strategy for allowed JSON objects.

JSONSchema drafts 04, 05, and 07 are fully tested and working. As of version 0.11, this includes resolving non-recursive references!

For details on how to use this strategy in your tests, see the Hypothesis docs.

Supported versions

hypothesis-jsonschema requires Python 3.6 or later. In general, 0.x versions will require very recent versions of all dependencies because I don't want to deal with compatibility workarounds.

hypothesis-jsonschema may make backwards-incompatible changes at any time before version 1.x - that's what semver means! - but I've kept the API surface small enough that this should be avoidable. The main source of breaks will be if or when schema that never really worked turn into explicit errors instead of generating values that don't quite match.

You can sponsor me to get priority support, roadmap input, and prioritized feature development.
