Behaviour Driven Development has gained traction as a mainframe tool for automated testing in the agile software development process. In this talk, the aim here is to shed some light upon how it is a welcome addition to the data engineer's toolbox for testing data pipelines and data as a product. Further we'll also see how BDD can act as enabler for GxP process from a regulatory and compliance perspective. We'll do this by using an example of a real world data pipeline, step by step. We'll extensively be using the python framework Behave for the walkthrough and example.
