kwfind

Running:

$ python kwfind.py ./dir ^[a-zA-Z]+_TESTResult.*

Or:

$ python kwfind.py ./dir "^(\+\d{1,2}\s)?\(?\d{3}\)?[\s.-]\d{3}[\s.-]\d{4}$"

Unit test scenarios:

Tests:

1. Expect if missing both arguments:
   • Return TypeError.
2. Expect if both empty string arguments:
   • Print Invalid directory and return None.
3. Expect if directory doesn't exist in filesystem:
   • Print Invalid directory and return None.
4. Expect if (x, y) passed:
   • Return dictionary whose count matches tuples in mock(s) of os.walk().
5. Expect if (x, y) passed:
   • Print z found and additional formatted text.
6. Expect if invalid regex:
   • Rrint Invalid... and return None.

Mocks:

1. os.walk()

Automated or manual E2E test scenarios:

pyenv automated script, VM, containerized machine, etc.:

1. Module should not fail on Python 2.7.x - 3.x.
2. Module should print missing packages if not installed.

VM:

1. Module should not fail on Windows, Mac, and Linux systems.

Performance:

1. Calculate time and space complexity and investigate:
   • Multithreaded approach
   • Distributed approach
