Identify and design boundary test cases

Design comprehensive manual test cases

Plan and execute exploratory testing session

Identify and test boundary values for input validation. Use when designing test cases for numeric ranges, dates, and string lengths.

Use decision tables to test complex business logic with multiple conditions. Use when testing rules and workflows with many input combinations.

Partition test input domain into equivalence classes to reduce test count. Use when testing multiple similar scenarios.

Experience-based testing technique that anticipates defects through intuition, domain knowledge, and common failure patterns. Use when supplementing systematic techniques with exploratory instinct.

Create and execute exploratory testing charters to discover defects through unscripted testing. Use when exploring new features or validating user scenarios.

Design tests from state machine models to verify correct transitions, guard conditions, and invalid state handling. Use for workflows, UI flows, protocols, and stateful components.

Design systematic test cases covering valid inputs, invalid inputs, and edge cases. Use when creating manual test suites.

Derive test scenarios from use case specifications to validate end-to-end user workflows including main success, alternate, and exception paths. Use for acceptance testing and requirements validation.
