Design comprehensive OA test cases
Designing Your Own Test Cases in an Online Assessment
Context
You are participating in a technical online assessment that provides minimal example tests and requires you to generate your own. Your goal is to establish a systematic and repeatable methodology for designing tests that efficiently uncover logic errors and edge cases.
Prompt
Describe your approach to the following:
- Creating a repeatable checklist of edge-case categories applicable to a broad range of algorithm and data-structure problems.
- Rapidly generating test inputs and computing their corresponding expected outputs.
- Comparing your solution's output against a reference answer (oracle), including scenarios where you must develop the oracle yourself.
- Determining when test coverage is sufficient, for instance, after crafting 5–10 carefully selected test cases.

Core dilemma
Balancing the need for comprehensive and robust test coverage with the severe time constraints and limited tooling of an online assessment environment, while also ensuring the correctness of the test oracle itself.
