TDD BDD
Test-Driven Development (TDD) is a method of developing software that is driven by tests. This means that the developers must first write the test cases before writing the code. BDD is an acronym for behavior-driven development. It's a behavior-based development approach.
TDD tests are developed in a variety of programming languages, including Java,.NET, Python, Ruby, and others. Given-When-Then steps are used to write BDD tests in a human-readable fashion. Non-technical people may read and comprehend these tests as well.
The scope is the key distinction between TDD and BDD. TDD is a development methodology. BDD, on the other hand, is a collaborative methodology.
When a test fails because the specified function does not exist, TDD recommends writing the simplest code possible to pass the test, then reworking to remove duplication, and so on. Creating an executable specification that fails because the feature isn't available, then writing the simplest code possible to make the spec pass in BDD. This process is repeated until a release candidate is ready to be delivered.
The test cases are written by the developers in TDD. Users or testers write automated specifications in BDD, which are then wired to the code under test by developers.
Because TDD tests are written in specific programming languages, they are difficult to interpret by non-programmers. Non-programmers can read BDD tests since they are written in a human-readable format.
