A discussion with Katharine Jarmul, aka kjam, about some of the challenges of data science with respect to testing.
Some of the topics we discuss:
- experimentation vs testing
- testing pipelines and pipeline changes
- automating data validation
- property based testing
- schema validation and detecting schema changes
- using unit test techniques to test data pipeline stages
- testing nodes and transitions in DAGs
- testing expected and unexpected data
- missing data and non-signals
- corrupting a dataset with noise
- fuzz testing for both data pipelines and web APIs
- datafuzz
- hypothesis
- testing internal interfaces
- documenting and sharing domain expertise to build good reasonableness
- intermediary data and stages
- neural networks
- speaking at conferences
