+## k6 Testing
+
+To run a k6 script tests, first you should run the whole project (see [**Running the Project**](#running-the-project)). 
+
+Then run the following command:
+
+```bash
+docker run --rm --network bazaar-network -v "$(pwd)/src/test/k6:/io" -w /io grafana/k6 run scripts/<test_name>.js
+```
+
+> [!NOTE]
+> If you are using Windows Powershell, you should replace `$(pwd)` with `"$($pwd.Path)"`.
+> ```bash
+> docker run --rm --network bazaar-network -v "$($pwd.Path)/src/test/k6:/io" -w /io grafana/k6 run scripts/<test_name>.js
+> ```
