 ### `npm test`
 
 Start continuous unit tests. We use [Jest](https://jestjs.io) to run end-to-end tests. Tests will rerun on changed files, or you can change modes by pressing 'a' to run ALL tests continuously.

-Start the end-to-end testing UI. We use [Cypress](https://cypress.io) to run end-to-end tests. This defaults to testing http://localhost:3000, as specified in `cypress.json`. You should start your test server using `npm start` first. You can override these values in your own `cypress.env.json` file to point to a remote server if you wish.

-To run a smoke test in headless mode, run `npm run test:e2e:smoke`. The current smoke test requires dashboards/workspace to already be created. In the future, we should refine the smoke tests to reset the database to an expected state before running the tests. More detail in [Cypress Best Practices](https://docs.cypress.io/guides/references/best-practices.html#Dangling-state-is-your-friend).

 ## Architecture
 
-At a high level, the Web UI uses the Iris API to communicate with the servers/workers necessary. For details on the Iris API,see the [Web Developers Guide](../WebDevelopersGuide.md). For more details on the sockets and ports used, see [Network Services](https://docs.deephaven.io/latest/Content/runbook/OpsGuide.htm?Highlight=socket%20ports#Network_Services) and [Web API](https://docs.deephaven.io/latest/Content/systemAdmin/sec_webAPI.htm) in our docs.
