jsonschema-test is a tool for writing and running tests against a given JSON Schema. You can write a set of test-cases including example JSON values and if they should validate or not against the given JSON Schema.

pip install jsonschema-test

To use jsonschema-test, you will need to write a collection of tests. The tests are decoupled from any language and are written in JSON.

A test suite is a collection of test's and test cases. See the test suite structure for more information

[
    {
        "description": "a person",
        "tests": [
            {
                "description": "validates with a name",
                "data": {
                    "name": "Kyle"
                },
                "valid": true
            },
            {
                "description": "fails validation without a name",
                "data": {
                },
                "valid": false
            }
        ]
    }
]

A JSON Schema to test.

{

        }
    },
    "required": [ "name" ]
}

There is a JSON Schema file for the test suite structure.

A test suite is a logical group of Test's. It's a simple JSON file with an array containing each test.

• description (string, required) - A short description of what this test tests.
• tests (array[Case], required) - A collection of test cases.
• skip (boolean, optional) - Whether to skip the test. This defaults to false.

• description (string, required) - The description of this test case.
• data (any, required) - The JSON used against the JSON Schema.
• valid (boolean, required) - If the data should validate or not.
• skip (boolean, optional) - Whether to skip the case. This defaults to false.
