Unit test results are occasionally put under different namespaces, depending on the type of the tests.

The issue is in the transform file nunit-to-junit.xsl.

Specifically, the cause is due to the firstTestName variable. The original is:

<xsl:variable name="firstTestName" select="results//test-case[1]//@name" />

The "fixed" version is:

<xsl:variable name="firstTestName" select="results/test-case[1]/@name" />

This fixes my current issue, but I don't know if it introduces any new (or old) issues.

I have attached an example nunit results file that will generate the error (one of the 3 Inflector.OrdinalizeTests testsuites has the name Inflector rather than Inflector.OrdinalizeTests)
