Ask For Tests Before Code

Test-first prompting improves implementation quality.

Best way to use it:

• Describe behavior.
• Ask for test cases.
• Review edge cases before implementation.

Copy-ready prompt:

Before writing code, propose tests for this behavior: [behavior]. Include happy path, edge cases, errors, permissions, and regression risks.

Quality check:

• Tests cover behavior.
• Edge cases are included.
• Implementation is not premature.

DropTicks note:

Use ChatGPT like a workstation, not a magic answer box. Give it the role, goal, input material, constraints, expected output format, and review criteria. The stronger your workflow, the better the result.
