PEG.js Test Suites
This directory contains various test suites and scripts to ensure PEG.js works correctly.
- Spec Suite: Runs various test's that ensure PEG.js and it's generated parsers are working as intended. All tests should always pass on all supported platforms.
- Benchmark Suite: It measures speed of the parsers generated by PEG.js on various inputs. Its main goal is to provide data for code generator optimizations.
- Impact Script: Measures impact of a Git commit (or multiple commits) on generated parsers speed and size.
