json-schema-tests

A node.js tool for testing JSON Schema validators against the JSON Schema Test Suite.

The npm package includes a copy of the JSON Schema Test Suite files from the time of publishing. The present version is 1.1.2-28-gaabcb34.

You must have CoffeeScript installed globally to use json-schema-tests

npm install -g coffee-script

If you install json-schema-tests globally, you can use it like this:

json-schema-tests path/to/validator_adapter.coffee # or .js

The "validator adapter" must export three fields, version, validator, and ignores.

• version: used to select the correct test suite. Must be either "draft3" or "draft4".
• validator: a function that takes a schema and a document, then validates the document against the schema. Return the result like this: {valid: true}
• ignores: specify any JSON Schema attributes that you choose not to test. See examples/jsck.coffee for the format.

To demonstrate a baseline, I've included a sycophantic validator in the examples. It always says the document is valid. The output for examples/yes.coffee looks like this:

Full text of that output is here.

Development

After cloning the repo, you'll need to acquire the test suite submodule:

git submodule update --init
