`junit` is the legacy Chef InSpec JUnit reporter, which is retained for backwards compatibility. It generates an XML report in Apache Ant JUnit format. The output format is 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 at runtime, but uses Nokogiri, a more heavyweight XML library, for testing. This design keeps packaging requirements lightweight and free of compiled dependencies.
