XSpec is a popular testing framework, originally created in 2008[CIR2017] for testing XSLT but it has since been extended to also support XQuery and Schematron.[WHATXSP] My experiment to use XSpec for testing iXML extended the process for testing XSLT so the scope of this section is limited to the XSpec process for XSLT. However, Amanda Galtman has published an article on how to test iXML using XQuery in BaseX with Markup Blitz.[GALMED]
