Tests

This library includes a sample testing utility which may be used to verify that changes to the processor maintain the correct output.

The test suite is included in an external repository:

https://github.com/json-ld/normalization

This should be a sibling directory of the rdf-canonize directory or in a test-suites dir. To clone shallow copies into the test-suites dir you can use the following:

npm run fetch-test-suite

Node.js tests can be run with a simple command:

npm test

If you installed the test suites elsewhere, or wish to run other tests, use the TEST_DIR environment var:

TEST_DIR="/tmp/tests" npm test

To generate earl reports:

# generate the earl report for node.js
EARL=earl-node.jsonld npm test

Benchmark

See docs in the benchmark README.
