Tech & Development Prompts Generate test cases that cover where code actually breaks — not just the happy path. This test case generator prompt creates structured test suites — unit, integration, E2E, API, UI, edge, regression, and negative — for any feature, function, user story, or bug fix, with preconditions, steps, expected results, automation recommendations, and requirement traceability. Paste into Claude, ChatGPT, or any AI chat, describe the feature or paste the function, and get a risk-focused test suite ready to execute or automate. Happy-path-only tests are not sufficient — this prompt targets where code most commonly breaks: numeric and string boundaries, permission edges, third-party dependency failures, race conditions, SQL injection patterns, and cross-tenant data access. Every expected result must be specifically verifiable ("returns correct result" is banned). Works with Claude, ChatGPT, or any AI chat model.
