1.1Why Prompt Structure Matters

A poor prompt produces poor tests. The difference between "write tests for login" and a structured prompt is the difference between a junior engineer guessing and a senior engineer analyzing requirements. LLMs are statistical pattern matchers -- the quality of their output is directly proportional to the specificity and structure of your input.

In test generation, this means you need to think of your prompt as a test specification document, not a casual request. Every piece of context you include (or omit) shapes the coverage, quality, and usefulness of the generated tests.
