parserTest — UI-driven log parser

Turn unstructured logs into structured ones, by people who hate regex

javalog parsingregexuiqa tooling

My first real internal project at a previous employer — a UI-driven log extraction tool. Engineers needed to pull specific fields from messy log streams, but most QA folks will not write regex from scratch. parserTest exposes a UI for building extraction rules: you point at the parts you want, name them, choose the format, and the tool generates the regex behind the scenes. The output is a clean, queryable structured log. Years before "log analysis SaaS" had a name, this was already running for the team.
