`junit` is the legacy Chef InSpec JUnit reporter. It generates an XML report in Apache Ant JUnit format. The output format may be considered nonstandard in several ways. New users are advised to use `junit2`.
`junit2` is an updated reporter that provides JUnit output according to the schema published by [Windy Road](https://github.com/windyroad/JUnit-Schema).
This reporter uses the REXML XML generator, but uses the more heavyweight XML library Nokogiri for testing. This is to keep packaging requirements lightweight and free of compiled dependencies.
