Test of boolean expressions
This page describes W3C SPARQL Working Group's SPARQL1.0 test suite.
The test manifests and entries are built automatically from manifest.ttl using a Rake task. Tests may be contributed via pull request to https://github.com/w3c/rdf-tests with suitable changes to the manifest.ttl and referenced files.

Non-zero numerics, non-empty strings, and the true boolean have an EBV of true
Zero-valued numerics, the empty string, and the false boolean have an EBV of false
The && operator takes the EBV of its operands
The || operator takes the EBV of its operands
The EBV of an unbound value or a literal with an unknown datatype is a type error, which eliminates the solution in question
Negating a type error is still a type error
