Test a Power BI custom visual before submitting it for publication

Before you publish your visual to AppSource, it must pass the tests listed in this article. It's important to test your visual before you submit it. If your visual doesn't pass the required test cases, it will be rejected.

For more information about the publishing process, see Publish Power BI visuals to Partner Center.

Testing a new version of a published visual

By default, Power BI loads the latest published version of the visual from AppSource, even if you import the visual from a local file. Version numbers consist of four digits in the following format: X.X.X.X.

When testing or updating a visual that's already published, make sure you're using the correct version of the visual without changing the GUID. To override the AppSource version with a local file version, enable Developer mode in either Power BI Desktop or Power BI service.

Important

When testing or debugging a new version of a visual that's available in AppSource, do not change the GUID of the visual. Use Developer mode instead.

Enable Developer mode in Power BI Desktop

In Power BI Desktop, Developer mode is valid for only one session. If you open a new Power BI Desktop instance for testing, you need to enable Developer mode again.

To enable Developer mode, follow these steps:

1. Open Power BI Desktop.
2. Select File > Options and settings.
3. Select Options.
4. In the Options window, from the CURRENT FILE list, select Report settings.
5. In Developer Mode, select the Turn on developer mode for this session option.

Enable Developer mode in Power BI service

In Power BI service, Developer mode is kept per user account. Whenever a user loads the package from the local file, Power BI will ignore the AppSource version of the visual.

To enable Developer mode in Power BI service, follow the instructions in Set up Power BI service for developing a visual.
