+OpenSearch Dashboards uses [Jest](https://jestjs.io/) for unit and integration tests, [Selenium](https://www.selenium.dev/) for functional tests, and [Cypress](https://www.cypress.io/) for backwards compatibility tests.

+In general, we recommend four tiers of tests:
 * Unit tests: Unit tests: small and modular tests that utilize mocks for external dependencies.
 * Integration tests: higher-level tests that verify interactions between systems (eg. HTTP APIs, OpenSearch API calls, calling other plugin). 
 * End-to-end tests (e2e): functional tests that verify behavior in a web browser.
+* Backwards Compatibility tests: cypress tests that verify any changes are backwards compatible with previous versions.
 
 # Requirements
 * Install the latest NodeJS, [NPM](https://www.npmjs.com/get-npm) and [Yarn](https://classic.yarnpkg.com/en/docs/install/#mac-stable)
