+## To run the tests locally
+```bash
+cd tests/e2e
+npm install
+npm test
+```
+## To debug the tests locally with VSCode
+Add the following configuration to your local ``launch.json``:
+```json
+{
+  "type": "node",
+  "request": "launch",
+  "name": "Debug e2e tests",
+  "runtimeArgs": [
+    "--inspect-brk",
+    "${workspaceRoot}/tests/e2e/node_modules/.bin/jest",
+    "--runInBand",
+    "--colors"
+  ],
+  "cwd": "${workspaceFolder}/tests/e2e",
+  "restart": true,
+  "console": "integratedTerminal",
+  "internalConsoleOptions": "neverOpen",
+  "port": 9229
+}
+```
+Now you can run the tests by clicking on the Play button, using that configuration. It should allow you to insert breakpoints and inspect variables.
+## To run the tutorials
+```bash
+cd tests/e2e
+node tutorials/<tutorial>.js [<user> <password>]
+```
