xmlunittest
Library using lxml and unittest for unit testing XML.
Decision gist · record as of 2026-08-14
Yes, if you generate XML and use unittest. The package is stable, has no known vulnerabilities, and low install friction. Dormant maintenance is a minor concern—it suggests no active development, but the core functionality is straightforward and unlikely to break. Use it when string-based XML comparison would be fragile or unreadable.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires lxml to be installed; lxml has C dependencies that may need compilation on some platforms.
- Low friction: pure Python wheel with a single runtime dependency on lxml.
- Maintenance is dormant (762 days since last release) but the repository is not archived and the package is marked Production/Stable.

What it is and what it does
xmlunittest is a TestCase subclass that adds assertion methods for validating XML documents as structured data rather than raw strings. It uses lxml and XPath to let you write tests that check namespaces, element values, attribute presence, and document structure without being brittle to formatting changes or attribute reordering.
You extend XmlTestCase, call assertXmlDocument() to parse your XML, then use methods like assertXpathValues(), assertXmlNamespace(), and assertXpathsUniqueValue() to validate specific parts of the tree. This is useful when your code generates XML and you want tests that survive cosmetic changes to the output while still catching structural problems.
Use it for
- Test XML output from code that generates configuration files, RSS feeds, or SOAP responses without brittle string comparisons.
- Validate that XML documents conform to expected namespaces and element structures using XPath queries.
- Check that optional XML elements and attributes are present or absent as expected in unit tests.
- Ensure attribute values match a set of allowed options across multiple elements in a single assertion.
- Verify uniqueness constraints on XML attributes across a document tree using XPath expressions.
