Stretching XPath: Three Testing Tales

This paper describes three testing situations that can be addressed by markup-technology functionality whose primary uses are fairly different from those testing situations. One testing situation involves ensuring that certain kinds of test verifications don’t pass for the wrong reason. Another situation involves testing an XSLT template both cleanly and compactly. The third situation involves reducing maintenance of schema-valid and schema-invalid XML fragments when testing a schema. Software testing frameworks are sometimes sparse in their own functionality, but the XSpec and BaseX software discussed here can use rich functionality from the XML technologies on which they rest.
