Test, test, test - from the very beginning to the end

This podcast emphasizes the importance of Test Driven Development (TDD), in particular the early formulation of test cases, in order to avoid misunderstandings and mistakes in software development. It argues that tests should not only be applied to finished software, but to all intermediate results, such as project plans or requirements descriptions. An example from the insurance industry illustrates how user stories can be specified with test cases to describe requirements in detail and validate them early. Identifying errors early saves time and effort.
