By clarifying "edge cases" (like what happens if a customer has a negative balance) during the specification phase, teams avoid discovering these issues halfway through coding.
Specification by Example replaces vague "shall" statements with concrete scenarios. Instead of saying, "The system should handle tiered discounts," a team practicing SbE would create a table: Gold | Order Value: $100 | Discount: 20% Customer Type: Silver | Order Value: $100 | Discount: 10% These examples serve three purposes simultaneously: Requirement: They define what the system should do. Test: They provide the exact criteria for success. Specification by Example
While SbE is a process—not a tool—it is often implemented using frameworks like or SpecFlow . These tools allow teams to write examples in plain language (Gherkin syntax) and link them to automated test scripts. This creates a "living documentation" system that evolves with the code. Conclusion By clarifying "edge cases" (like what happens if
is a collaborative approach to defining requirements and functional tests based on capturing and clarifying requirements using realistic examples instead of abstract statements. It bridges the communication gap between business stakeholders, developers, and testers, ensuring that the software being built aligns perfectly with business goals. The Core Problem: The Translation Gap Test: They provide the exact criteria for success
