## Abstract

Test of boolean expressions

This page describes W3C SPARQL Working Group's SPARQL 1.0 test suite.

### Contributing Tests

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.

## Test Descriptions

dawg-boolean-literal: Test literal 'true'
  type
    mf:QueryEvaluationTest
  approval
  action
  result
    result-boolean-literal.ttl
dawg-bev-1: Test 'boolean effective value' - true

  Non-zero numerics, non-empty strings, and the true boolean have an EBV of true

  type
    mf:QueryEvaluationTest
  approval
  action
  result
    result-bev-1.ttl
dawg-bev-2: Test 'boolean effective value' - false

  Zero-valued numerics, the empty string, and the false boolean have an EBV of false

  type
    mf:QueryEvaluationTest
  approval
  action
  result
    result-bev-2.ttl
dawg-bev-3: Test 'boolean effective value' - &&

  The && operator takes the EBV of its operands

  type
    mf:QueryEvaluationTest
  approval
  action
  result
    result-bev-3.ttl
dawg-bev-4: Test 'boolean effective value' - ||

  The |  | operator takes the EBV of its operands

  type
    mf:QueryEvaluationTest
  approval
  action
  result
    result-bev-4.ttl
dawg-bev-5: Test 'boolean effective value' - optional

  The EBV of an unbound value or a literal with an unknown datatype is a type error, which eliminates the solution in question

  type
    mf:QueryEvaluationTest
  approval
  action
  result
    result-bev-5.ttl
dawg-bev-6: Test 'boolean effective value' - unknown types

  Negating a type error is still a type error

  type
    mf:QueryEvaluationTest
  approval
  action
  result
    result-bev-6.ttl
