Test Writing Prompt Builder

Use AI to write or improve tests by supplying code, expected behavior, edge cases, and the exact test target before asking for suggestions.

Open builder See all prompt guides

Use it when you need to

Draft tests for a function, class, API, or bug regression.
Ask AI to identify missing edge cases in existing test coverage.
Turn production incidents into stronger regression-test prompts.

Prompt Raven helps you pin down

The current code, system context, or failing behavior.
The technical constraints that limit the solution space.
The evidence the model should reason from, such as logs or diffs.
The output shape you want: analysis, plan, tests, or code.
The risks you want the model to avoid while helping.

Why this focused page exists

AI writes better tests when it sees the code and expected behavior. This page helps you provide the context that separates useful tests from generic ones.
