+### Testing functions in online mode
+
+Testing your cloud functions online is very simple and easy.
+
+For that, you only have to set the variables localted in the env.example.json inside /functions folder. (Remember to rename the file to env.json)
+
+After that, navigate to the /functions folder and execute **npm test** in your terminal.
+
+Note: For finding your service account key you should go to your proyect in the Firebase dashboard, click on **_Project settings_** and then click on **_Service accounts_** tab. After that you'll be able to click on **_Generate new private key_** button and a json file containing your service account's credentials will be downloaded. Place that file in your project and include the location of it into the **_"serviceAccountKey"_** in your env.json file.
+
+_Warning: Use extra caution when handling service account credentials in your code. Do not commit them to a public repository, deploy them in a client app, or expose them in any way that could compromise the security of your Firebase project._

 ### Deployment
