Talk: What can go wrong with testing an ETL pipeline?
With businesses wanting to make data-driven decisions, software engineers find themselves implementing more data-intensive applications. More engineers are jumping from application software development to data engineering. Yet, when it comes to testing data-intensive systems, the lessons that we have learned from writing application code seem to be forgotten, making one worry about generating data instead of having a good testing strategy. This talk will be about how a testing strategy evolved in one of the analytics projects I was involved in and how we learned these old lessons the hard way.
