 ### Types of Tests
 
 - **End-to-End (E2E) Tests**: Simulate real user behavior on the web interface. They check critical user flows, data display, error handling, and the responsiveness of the application.
-- **Unit Tests**: Verify the correct functioning of JavaScript/TypeScript components and functions in isolation.

+### End-to-End (E2E) Tests
+
+- **Fetch Measurements Button**:
+  - Verifies that the "Fetch Measurements" button is visible and functional on the main page.
+  - Tests fetching timeseries data with a valid user-room-device selection, ensuring the main chart is displayed and no "no data" message appears.
+  - Tests fetching timeseries data with an invalid user-room-device selection (e.g., changing the user to "Sylvan"), ensuring the main chart is not displayed and the "no data" message is shown.
+
+#### Important Notes
+The E2E tests use a web-app development image deployed on https://app.mse.kb28.ch/ for the moment. Because there is a problem with the service image in the CI. The environment variables cannot be set correctly to the job's service. An issue is opened to fix this problem: [#37].
+
+### Unit Tests
+
+- **Serie Component**:
+  - Checks that a `Serie` instance initializes with the correct properties.
+  - Validates that the correct label is returned for temperature and humidity types.
+  - Ensures the label "Unknown" is returned for unknown types.
+  - Verifies that temperature and humidity data are formatted correctly by `getSerie()`, including label, color, and data structure.
+  - Ensures unknown types are handled appropriately in `getSerie()`, defaulting to the correct color and axis.
