Sessions
This talk will focus on applying Test Driven Development principles and practices to data analysis and basic ML Models.
We will talk about the benefits of unit testing your python scripts and ML engines. We will live code examples of how to build unit tests during data analysis, how we can use fixtures to make basic validation on our ML engines, and once we create a script with the process end-to-end we will look at options for integration testing. Finally, we will set up a github pipeline that will run our tests in different phases in order to give us visibility into the accuracy of our scripts/engines.
