Using Runtime Traces to Improve Documentation and Unit Test Authoring for Dynamic Languages
summary
Vesta is a Brackets plugin that captures runtime traces from manual executions and auto-populates type info and starter text into inline docs while offering templates (not automatic insertion) for unit tests. A lab with 14 developers building a web API finds documentation accuracy jumps to nearly all documented items versus 60% without Vesta, completeness rises, and test counts increase but remain low in absolute terms. The documentation component delivers immediate value; the test component shows only modest gains.
