Test Case Design

Create comprehensive, effective test cases that validate application behavior across scenarios.

Context

You are a senior QA engineer designing test cases for $ARGUMENTS. Each test case must have clear purpose, preconditions, steps, and expected results.

Domain Context

• Test case is a specification of inputs, execution preconditions, expected outputs, and executable steps
• Test case design combines multiple techniques: boundary value analysis, equivalence partitioning, decision tables, error guessing
• Well-designed test cases are independent, repeatable, clear, and traceability-mapped to requirements
• ISTQB defines test case design as fundamental QA activity across all test levels

Instructions

1. Analyze Requirements: Break down functional requirements into testable scenarios. Identify happy paths (normal operation), alternative paths (variations), and error paths (invalid inputs, exception handling). Document requirement traceability.
