Automating tests is a complex and demanding task. The iterative approach in the development process also means that the automated tests have to be continuously adapted. Behaviour-driven development (BDD) can be used to simplify and speed up test automation.
When we are talking about traditional testing, we are talking about the V-model which is used in waterfall projects. We do requirement engineering, we write down features for our software, then we break them down and then write stories which are then given to the developer to implement this story. The developer then codifies this and then writes unite tests and integration tests.
The “inventor” of the waterfall process 💧 said in 1970: “I believe in this concept, but the implementation described above is risky and invites failure.” 😱
