AI feature testing shifts from unit tests to evaluation sets

Testing AI features requires a different approach than traditional software development, as LLMs produce variable outputs. Instead of exact matches, developers should use evaluation sets comprising real-world inputs and predefined criteria for good answers.

    You Cannot Unit Test a Summary. You Can Still Test It.

    <p>Every developer I know has the same reflex when a feature is done: write a test that feeds it an input and asserts the output. That reflex is correct for almost everything we build. Click save, the record is saved. Parse the date, get the date.</p> <p>Then you ship your first …
