+# How to add Cypress tests
+
+When making changes to JavaScript, CSS, or HTML which could change the functionality or layout of a page, it's important to add corresponding [Cypress](https://docs.cypress.io) integration tests.
+
+To learn how to write Cypress tests, or 'specs', please see Cypress' official [documentation](https://docs.cypress.io/guides/getting-started/writing-your-first-test.html).
+
+> Note: When writing tests for freeCodeCamp, remember to add `/* global cy */` to the top of the file to avoid ESLint issues.
+
+### Where to add a test
+
+- Cypress tests are in the `./cypress` directory.
+
+- Cypress tests for a curriculum module are in the corresponding curriculum directory, i.e. `cypress/integration/learn/responsive-web-design/basic-css/index.js`.
+
+### How to run tests
+
+**1. Ensure that MongoDB and client applications are running**
+
+  - [Start MongoDB and seed the database](/how-to-setup-freecodecamp-locally#step-3-start-mongodb-and-seed-the-database)
+
+  - [Start the freeCodeCamp client application and API server](/how-to-setup-freecodecamp-locally#step-4-start-the-freecodecamp-client-application-and-api-server)
+
+**2. Run the cypress tests**
+
+  To run tests against production builds, replace `dev` with `prd` below.
+
+  - To run all tests in the `./cypress` directory:
+
+    ```console
+    npm run cypress:dev:run
+    ```
+
+  - To run a single test:
+
+    ```console 
+    npm run cypress:dev:run -- --spec=cypress/pathToYourSpec/youSpecFileName.js
+    ```
+
+  - To create a development build, start the development server, and run all existing cypress end-to-end tests:
+
+    ```console 
+    npm run e2e:dev:run
+    ```
