The JSON-LD Test Suite is a set of tests that can be used to verify JSON-LD Processor conformance to the set of specifications that constitute JSON-LD. The goal of the suite is to provide an easy and comprehensive JSON-LD testing solution for developers creating JSON-LD Processors.
Tests are defined into compact, expand, flatten, frame, normalize, and rdf sections:
PositiveEvaluationTest. For negative tests, the expected result is an exception matching an error code defined for JsonLdErrorCode. For positive tests, the expected results can be compared using JSON object comparison with the processor output.
To run the tests, create a test runner which will run through each test manifest
and execute the tests defined within the manifest using the rules associated with
@type defined for the test case as defined in the test vocabulary.
processingMode is set explicitly in a test entry,
processingMode is compatible with both
json-ld-1.1. Otherwise, a JSON-LD 1.0 processor should not run
json-ld-1.1 and a JSON-LD 1.1 processor should not run
Note that property values are typed, and those which are typed as
be treated as IRIs relative to the manifest test base. In particular, this means that
input, context, frame, and expandContext are to be
passed as IRIs to the API methods being tested.
More details for running different types of tests are also defined in the test vocabulary.
If you would like to contribute a new test or a fix to an existing test, please follow these steps:
Optionally, you can ask for direct access to the repository and may make changes directly to the JSON-LD Test Suite source code. All updates to the test suite go live within seconds of committing the changes to GitHub via a WebHook call.
In order to add a unit test, you must follow these steps:
The test suite is designed to empower JSON-LD processor maintainers to create and add tests as they see fit. This may mean that the test suite may become unstable from time to time, but this approach has been taken so that the long-term goal of having a comprehensive test suite for JSON-LD can be achieved by the JSON-LD community.
