# eslint and stylelint
npm run lint

# eslint only

To run the full suite of tests:

npm test

Alternatively, tests can be selectively run:

# unit tests
npm run test:unit

# aXe accessibility tests

# translations tests
npm run test:translations

Note: The axe tests require prefers-reduced-motion emulation to be turned on in the dev console if debugging in a local browser.

This repo uses @brightspace-ui/testing's vdiff command to perform visual regression testing:

# vdiff
npm run test:vdiff

# re-generate goldens
npm run test:vdiff -- --golden
