FAQPage Schema

How do I understand a new codebase quickly without reading implementation details?▼

To understand a new codebase quickly, analyze test suites to extract behavioral specifications and contracts. This approach reveals functionality through test names and setup patterns without requiring deep implementation analysis.

How do I extract behavioral specifications from test files?▼

Extract behavioral specifications by reading test file names and setup configurations. Test names serve as a behavioral catalog, while fake implementations provide contract documentation for the codebase.

Can I use test suite analysis to map dependency graphs?▼

Yes, test suite analysis can map dependency graphs by examining test setup routines. These construction patterns reveal how components interact and depend on each other within the codebase.

What is the best way to explore code through contract documentation?▼

The best way to explore code through contract documentation is utilizing fake implementations within test suites. Fakes serve as explicit contracts, outlining expected behaviors and interactions without delving into source code.

Does exploring codebases through test files work for legacy code?▼

Exploring codebases through test files works for legacy code if test suites exist. It requires reading available test file names, setup, and fakes to extract behavioral specifications and construction patterns effectively.

When should I not use test files for code exploration?▼

You should not use test files for code exploration when the test suite is sparse, outdated, or absent. Without comprehensive test names and fakes, extracting accurate behavioral specifications and dependency graphs is not feasible.
