  • Article

Important

We've introduced the Teams Toolkit v5 extension within Visual Studio Code. This version comes to you with many new app development features. We recommend that you use Teams Toolkit v5 for building your Teams app.

Teams Toolkit v4 extension will soon be deprecated.

You can test your Teams app after integrating with Microsoft Teams. To test your Teams app, you need to create at least one workspace in your environment. You can use Teams Toolkit for testing your Teams app:

  • Locally hosted in Teams: Teams Toolkit locally hosts your Teams app by sideloading it into Teams for testing in local environment.

  • Cloud-hosted in Teams: For testing your Teams app remotely, you need to Cloud-host it using provisioning and deploying on Microsoft Azure Active Directory (Azure AD). It involves uploading your solution to the Azure AD and then upload into Teams.

Note

For production-scale debugging and testing, we recommend that you follow your own company guidelines to ensure you are able to support testing, staging, and deployment through your own processes.

Locally hosted environment

Teams is a cloud-based product that requires all services it accesses, to be available publicly using HTTPS endpoints. Local hosting is about sideloading into Teams for testing in local environment.

Note

Although you can use any tool of your choice for testing, we recommend you to use ngrok.

Cloud-hosted environment

To host your development and production code and their HTTPS endpoints, You need to remotely test your teams app using provisioning and deploying on Azure AD. You need to ensure that all domains are accessible from your Teams app listed in the validDomains object in the manifest.jason file

Note

To ensure a secure environment, be explicit about the exact domain and subdomains you reference and those domains must be in your control. For example, *.azurewebsites.net is not recommended, however contoso.azurewebsites.net is recommended.
