I am writing a regex that validates timer input, timer only accepts 0 and between 5 and 120 min in both hour format (1:30) and min format (90).
It fails on "2:01", "2:59" and "0:01", "0:02", "0:03", "0:04", "0:1", "0:2", "0:3", "0:4"
import re
import pytest
pattern = re.compile("^(?:0|[5-9]|[1-9][0-9]|1[01][0-9]|120|[0-2]:[0-5]?[0-9])$")
@pytest.mark.parametrize("zeros", ("0", "0:0", "0:00"))
def test_valid_0_format(zeros):
assert pattern.match(zeros)
@pytest.mark.parametrize("zeros", ("0:", "0::", "0:::", "0::0"))
def test_invalid_0_format(zeros):
assert not pattern.match(zeros)
@pytest.mark.parametrize("minutes", range(5, 121))
def test_valid_min_format_from_5_to_120(minutes: int):
assert pattern.match(f"{minutes}")
@pytest.mark.parametrize("time", ("3", "4"))
