  // - {String} info: a summary of the test case
  // - {String} property: the CSS property that should be tested
  // - {String|undefined} tagName: the tagName of the element we're going to test.
  //                               Optional only if there's a createTestElement property.
  // - {Function|undefined} createTestElement: A function that takes a node as a parameter
  //                                           where elements used for the test case will
  //                                           be appended. The function should return the
  //                                           element that will be passed to
  //                                           isPropertyUsed.
  //                                           Optional only if there's a tagName property
  // - {Array<String>} rules: An array of the rules that will be applied on the element.
  //                          This can't be empty as isPropertyUsed need a rule.
  // - {Integer|undefined} ruleIndex: If there are multiples rules in `rules`, the index
  //                                  of the one that should be tested in isPropertyUsed.
  // - {Boolean} isActive: should the property be active (isPropertyUsed `used` result).
