I didn't say that it was unit testing, I said that you could use one of
the XSLT unit testing frameworks (among other tools) to do it, since
many of the frameworks explicitly support it:

   If you want to test the stylesheet as a whole, the easiest thing to
   do is to create external input/output files and reference them. [1][5]

   XSLT transformation test case. This is achieved by passing the
   contents of the <utfx:source> fragment through the XSLT stylesheet
   that is being tested and asserting that the result is the same as the
   contents of the <utfx:expected> fragment. [2]

   Knowing the input XML, input stylesheet and expected output XML we
   can assert that the output of the transformation matches the expected
   output as follows [3]

   Often template requires current node to be set up. By default, it is
   a root node of the input document... [4]
