Clearly functions are ideal for unit testing because unlike templates they
have no context dependencies. But I think you can do it with templates too.
I often exploit the XSLT 2.0 feature that allows a stylesheet to be executed
starting at a named template; you can insert a named template that is there
solely for testing purposes, for example

<xsl:template name="test-table-rendition">
  <xsl:apply-templates select="(//table)[1]"/>
</xsl:template>

or if you prefer you can compare the output with expected results using
deep-equal().

Having said that, my main use for this technique is with a multi-phase
stylesheet, allowing each phase to be tested independently of the others.
