Describe the bug

The test will pass with only one number present using this regex /(?=\w{5})(?=\D*\d)/

To Reproduce

Steps to reproduce the behavior:

  1. Go to '...'
  2. Use /(?=\w{5})(?=\D*\d)/ as the code solution.
  3. The test will pass.

Expected behavior

The test should fail as a word with only one number at the end will be found with the regex. This was tested on regextester.com

Desktop (please complete the following information):

  • OS: [Debian Linux]
  • Browser [Chrome]

It looks like there is no test present to assert that an input with only 1 digit like abcd1 fails. I can take this one.
