This repository contains around 40,000 tests for XPath and XQuery, developed originally by the W3C XQuery and XSLT Working Groups, and subsequently expanded by members of the QT4CG W3C Community Group, and by individual contributors.
This started as a fork of the qt3tests repository published by W3C. The original tests have been retained in their entirety, changing only when the results are no longer valid, and many new tests have been added for new features proposed for the 4.0 versions of the specifications. Efforts are made from time to time to pull new QT3 tests across into this repository when gaps are found in the test coverage.
The tests cover both XPath and XQuery.
There is metadata with each test to indicate its dependencies (which language versions and optional language features it requires), and its required environment (resources such as source XML files).
The metadata defines the expected results of each test, as a set of one or more assertions.
The test suite does not include test drivers for particular XQuery implementations.
Further information about the test suite is available in various documents in the "guide" directory.
Change control on the test suite is based on informal consensus. Adding new tests is always welcome (but please make sure they pass on at least one implementation first). Existing tests should not be modified (except in trivial ways such as improving the description) without some attempt to ensure that the change has consensus. Submitting a PR is an appropriate way of doing this.
