Part I of the book describes the use of constraints for data validation and shows how tools can use a machine-learning-style approach to infer suitable constraints from data. This is illustrated using the command-line tools in the open-source Python tdda library, as well as alternatives. These can be used regardless of the programming language in use. Part II covers reference testing of analytical pipelines and processes. Again, there is support in the tdda library for this, including automatic test-generation capabilities for testing software in any language. There are specific discussions of testing models and modeling, including the large language models used in chatbots, coding bots, and summarizers. Part III covers broader kinds of errors that can occur in analysis, including
errors of formulation, when the problem domain, methods or libraries are misinterpreted;
errors of process, as developed analytical processes are used;
errors of applicability, when analytical processes are used in situations for which they were not designed;
errors of communication, when valid analyses are misinterpreted; and
errors of judgement, when harmful analyses are carried out.
Extensive checklists are provided that can be used to improve quality before, during, and after analysis.
Test-driven data analysis can be thought of as a sibling to reproducible research, with similar concerns, but greater emphasis on automated testing, and less requirement for a human to reproduce results.
Key Features:
Prevents costly errors in analytical processes before they reach production through automated data validation and reference testing of data pipelines.
Provides actionable checklists for issues beyond the reach of automated testing.
Equips readers with open-source Python tools and language-agnostic command-line interfaces.
Addresses testing challenges for modern LLM-based systems including chatbots and coding assistants.
Instills in analysts an inner voice that is always asking: “How is this misleading data misleading me?”
