+## A fuzzer that generates random boolean values for testing.[br]

+## This is useful for testing code paths that
+## depend on boolean conditions, flags, or toggle states.[br]

+## [b]Usage example:[/b]
+## [codeblock]
+## func test_toggle_feature(fuzzer := BoolFuzzer.new(), _fuzzer_iterations = 100):
+##     var enabled := fuzzer.next_value()
+##     my_feature.set_enabled(enabled)
+##     assert_bool(my_feature.is_enabled()),is_equal(enabled)
