Caution is needed when using QuantestPyError as a mother class because...

try:
    assert_is_fuga()
except QuantestPyAssertionError:
    print("hoge") # called when QuantestPyAssertionError

try:
    assert_is_fuga()
except QuantestPyError:
    print("hoge") # called when QuantestPyAssertionError and QuantestPyError

try:
    assert_is_fuga()
except Exception:
    print("hoge") # called when TypeError, KeyError, ...., QuantestPyAssertionError and QuantestPyError
