/**
 * Tests whether all predicates work with the extraction in attributes that are not collections.
 *
 * Extraction mechanism: CUSTOM EXTRACTORS.
 *
 * The trick here is that each extractor is registered under the attribute name like "brain.iq".
 * It is illegal in the production usage, but it enables reusing the test cases from
 * SingleValueAllPredicatesReflectionTest without any code changes, so it is used here.
 * That is the reason why this test may extend the SingleValueAllPredicatesReflectionTest, and the only difference
 * is the registration of the Extractors.
 *
 * This test is parametrised. See SingleValueAllPredicatesReflectionTest for more details.
