XSpec is a unit test and behaviour driven development (BDD) framework for XSLT and XQuery. I picked up this open source project at work for testing our XSLT and I’m now actively contributing to it together with the XSpec community.
XSpec v0.5.0 has just been released and is the new XSpec release after 5 years. It includes new features like XSLT 3 support, JUnit report for integration with Continuous Integration tools, support for Saxon-B, etc. It also fixes long standing regression bugs as well as integration bugs in the code coverage, provides feature parity between the shell and batch scripts, integrates an automated test suite, and updates the documentation in the wiki.
