Tell us what’s happening:
Describe your issue in detail here.

I do not understand this error message:

Traceback (most recent call last):
  File "main.py", line 10, in <module>
    ports = port_scanner.get_open_ports("104.26.10.78", [8079, 8090])
  File "/home/runner/portscan/port_scanner.py", line 26, in get_open_ports
    host_ip = checkTarget(target)
  File "/home/runner/portscan/port_scanner.py", line 13, in checkTarget
    host = socket.gethostbyaddr(target)
socket.herror: [Errno 1] Unknown host
exit status 1

It most likely means that ip address doesn’t have corresponding host name.

I added it when possible, but still some errors I don’t understand. Example:

FAIL: test_port_scanner_url_multiple_ports (test_module.UnitTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/runner/portscan/test_module.py", line 22, in test_port_scanner_url_multiple_ports
    self.assertEqual(actual, expected, 'Expected scanning ports of URL address to return [22, 80].')
AssertionError: 'Open ports for scanme.nmap.org (45.33.32.156)\nPORT     SERVICE\n22       \n80' != [22, 80] : Expected scanning ports of URL address to return [22, 80].

Looks like the function returns the full text also in case when only list is expected as a returned value.
