Unit Test Writer Prompt for Copilot

This is the Copilot version of the unit test writer prompt: tests that cover the edge cases you would forget, not just the happy path. It is formatted the way Copilot takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.

Using this prompt with Copilot

Copilot is grounded in Microsoft 365 work context: prompts that name the artifact (the email, the deck, the document) and the audience get the most from it. This version is framed around the work product.

Replace the bracketed placeholders — [PASTE THE FUNCTION OR CODE], [LANGUAGE AND TEST FRAMEWORK] — with your own details before pasting.
