  I am not sure what you mean by "duplicate".  The principle
is simply to write little pieces of code that each setups
values, exercizes the component under test and then apply
assertions on the result.  Sounds familiar ?-)

  How it is implemented is by generating XSLT stylesheets
that have a copy of the pieces of XSLT code, as well as code
generated from assertions (and others), and that imports the
tested stylesheets.

  For instance:

    <t:test>
      <xsl:variable name="input">
        ...
      </xsl:variable>
      <xsl:variable name="expected">
        ...
      </xsl:variable>
      <xsl:apply-templates select="$input" t:variable="result"/>
      <t:assert-deep expect="$expected" select="$result"/>
    </t:test>

will generates something with the same taste as:

    <xsl:import href="test-stylesheet.xsl"/>

    <xsl:template name="some-id">
      <xsl:variable name="input">
        ...
      </xsl:variable>
      <xsl:variable name="expected">
        ...
      </xsl:variable>
      <xsl:variable name="result" as="item()*">
        <xsl:apply-templates select="$input"/>
      </xsl:variable>
      <xsl:if test="not(deep-equals($expected, $result))">
        <xsl:sequence select="
	    error(xs:QName('t:ASSERT'), 'Error message')"/>
      </xsl:if>
    </xsl:template>

  I am not sure that answers your question?
