Over the next few weeks Big Data LDN will be revisiting some of the highlights from our 2019 Conference in November as part of our Refresh series. More than 130 sessions at Big Data LDN 2019 were recorded split across 8 distinct content streams; DataOps, Data-Driven, Self-Service Analytics, Customer Experience, Governance and Master Data Management, AI, Fast Data and  BluePrint (Data Architecture). We will be releasing a video daily, delivered by a leading member of the user, vendor or consultancy community on a range of topics.

As more models are being developed to help businesses understand and serve customers better, it is crucial to ensure the code written behind these model pipelines have been sufficiently tested so the various components perform as expected. In our latest video Tola Alade of Lloyds Banking Group demonstrates unit testing using pytest, a python based test framework and gives practical examples of how to increase trust in your model pipelines by writing good unit tests.
