Can TestRunner Be Run Only in Sandbox and/or Automatically on Extension Publish?

Hi everyone,

I’m currently learning and trying to deepen my understanding of working with TestRunner codeunits in Business Central, and I have two related questions:

1. Is it possible to automatically run a TestRunner codeunit every time an extension is published to a sandbox environment?
Ideally, I’d like the TestRunner to execute immediately after publishing.

2. Can this behavior be restricted to sandbox environments only?

I want to ensure that the TestRunner runs in sandbox environments but does not execute when the extension is published to production.

I’ve looked into triggers like 'OnInstallAppPerCompany', but I’m unsure if this is the recommended approach or if there are better patterns (especially for environment-specific execution).

Has anyone implemented something similar or can suggest best practices?

Thanks in advance!

Hello,

I have one suggestion: rather than wanting to run the test codeunit every time you publish, you can use the built-in VS Code feature to run test codeunits directly from VS Code without publishing. Just run them from there.

Note: Make sure you have SubType set to Test, and the procedure type is also set to [Test].

Hope this helps resolve your issue.

@Yash_Mistry Thank you for your answer. I now understand how to run tests directly in VS Code. However, I’m still not clear on the purpose of a TestRunner. Could you elaborate on when and why it should be used?

This usually happens when the dimension isn’t properly configured or linked in the posting setup. Make sure the dimension is active, assigned correctly to the relevant master data (like customer, vendor, or item), and included in the account structure or posting profile. Also, try refreshing or revalidating the setup after changes sometimes the system doesn’t reflect updates immediately.
