xUnit.net XML Format v2

Several runners—including the console and MSBuild runners—are capable of generating XML reports after tests have been run. Some of those runners also support running XSL-T transformations against that XML (some built-in examples include transformations to HTML and NUnit format). This page documents the format of the XML emitted from v2 (and later) runners.

The schema-version attribute on the assemblies element identifies the schema version of the document. Since this attribute was introduced in schema version 2, it should be assumed that the absence of this attribute implies schema version 1. It's also important to note that schema versions are unrelated to versions of xUnit.net and their runners; you should only make assumptions about supported features in the XML file based on schema-version and not based on the version of xUnit.net.

The top level element of the document is the assemblies element.

Note

Any child element that doesn't link to specific documentation is an element that contains text, rather than child elements and/or attributes. Older runners will place this text in a CDATA block; newer runners will just put the text directly into the element. XSL-T (and most parsers) won't differentiate between naked text vs. a CDATA block.

Note

If you are looking for documentation on the deprecated XML format supported by xUnit.net v1, see the xUnit.net XML Format v1 documentation page.
