Following xspec:
<x:description xmlns:x="http://www.jenitennison.com/xslt/xspec"
stylesheet="identical.xsl">

<x:scenario label="Test combination of expect content and @test
attribute">
<x:context>
<topic>
<body>Body</body>
</topic>
</x:context>

<x:expect label="Should select one element from result and compare
to content" test="descendant::body">
<body>Body</body>
</x:expect>
</x:scenario>

</x:description>

using identity transformation:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output indent="no"/>

<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>

<xsl:template match="*">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>

I've tracked down the problem. When test attribute is specified and expect
have context elements results are wrapped in document node. When expected
content is simple sequence.

Expected is evaluated using following function:
<xsl:variable name="impl:successful"
as="xs:boolean"
select="test:deep-equal($impl:expected, if (
$impl:with-context ) then $impl:context else $x:result, 2)"/>

In our case $impl:with-context is true(). So we using $impl:context which
is evaluated as:
<xsl:variable name="impl:context" as="item()?">
<xsl:choose>
<xsl:when test="$impl:context-tmp instance of node()+">
<xsl:document>
<xsl:sequence select="$impl:context-tmp"/>
</xsl:document>
</xsl:when>
<xsl:otherwise>
<xsl:sequence select="$impl:context-tmp"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>

$impl:context-tmp contain nodes selected by @test attribute of x:excpect.
As result they wrapped into document.

Question why?

Solution: remove impl:context variable and rename $impl:context-tmp to
$impl:context

I discovered the same thing while working on some of my own test cases.

This issue has existed since May 2012; I have therefore forked the xspec
repository, where this bug has been corrected (and a test case added):
