snap-shot-it is a smarter snapshot utility for Mocha and BDD test runners that enables data-driven testing. It spies on the global `it` function to accurately capture test information, making it compatible with transpiled code, and provides intelligent diffing for objects, arrays, and multi-line text. The tool also supports advanced features like named snapshots, chunked snapshots, and pruning unused snapshots, making it ideal for developers using Mocha or other BDD frameworks who want efficient snapshot testing with clear, maintainable test output.
