JSON Schema Test Suite

This repository contains a set of JSON objects that implementors of JSON Schema validation libraries can use to test their validators.

It is meant to be language agnostic and should require only a JSON parser.

The conversion of the JSON objects into tests within your test framework of choice is still the job of the validator implementor.

Structure of a Test

If you're going to use this suite, you need to know how tests are laid out. The tests are contained in the tests directory at the root of this repository.

Inside that directory is a subdirectory for each draft or version of the schema. We'll use draft3 as an example.

If you look inside the draft directory, there are a number of .json files, which logically group a set of test cases together. Often the grouping is by property under test, but not always, especially within optional test files (discussed below).

Inside each .json file is a single array containing objects. It's easiest to illustrate the structure of these with an example:

        "description": "the description of the test case",
        "schema": {"the schema that should" : "be validated against"},
        "tests": [
                "description": "a specific test of a valid instance",
                "data": "the instance",
                "valid": true
                "description": "another specific test this time, invalid",
                "data": 15,
                "valid": false

So a description, a schema, and some tests, where tests is an array containing one or more objects with descriptions, data, and a boolean indicating whether they should be valid or invalid.


Draft 3 and 4 should have full coverage. If you see anything missing or think there is a useful test missing, please send a pull request or open an issue.

If you see something missing or incorrect, a pull request is most welcome!

There are some sanity checks in place for testing the test suite. You can run them with bin/jsonschema_suite check. They will be run automatically by Travis CI as well.
