Basis Path Testing in Software Testing

Testlodge

Basis path testing in software testing is a white box method where the tester examines the codebase to identify all possible paths that could be taken by the user to achieve their aims. These paths are then written as test cases to ensure all the different identified scenarios in the main branches are covered. Higher test coverage is then achieved when test cases are executed, typically through a form of unit testing.

The value of a prototype is in the insight it imparts, not the code being written. Prototyping lets us fail fast and cheap, or get the data to make a concrete decision on direction. It helps answer the question, "What happens if we try this?" Most significantly, prototyping provides us with the guardrails to safely and productively fail.
