Writing Robust Tests for Data & Machine Learning Pipelines

Read Original

This technical article analyzes the brittleness of tests in data and machine learning pipelines. It examines why tests often break despite correct new code, using a recommendation system pipeline as an example. The author details testing scopes (unit, integration, functional), demonstrates the impact of new data/logic, and provides concrete suggestions for creating more robust and less fragile pipeline tests with shorter feedback loops.
