-/**
- * Tests attribute parsing and handling of whitespace in attribute values.
- *
- * @param type Name of the type being tested (only for test output)
- * @param target The element that should be tested
- * @param attribute The name of the attribute that should be tested
- * @param expected The fallback/default value that is the expectation for invalid values
- * @param whitespace An array of strings that are valid whitespace characters
- * @param valid An array of strings containing valid attribute values
- * @param invalid An array of strings containing invalid attribute values
- * @param garbage An array of strings containing values that would make a valid value invalid when concatenated
- * @param assert_valid_custom A function for asserting validity of a valid value, arguments passed to this function: the element and the string from valid values array
- * @param assert_invalid_custom A function for asserting that an invalid value results in the expected default value, arguments passed to this function: the element and the expected value
