A decorator approach to unit testing.

Unit testing with decorators

Features

• run ./beta.py -f f.py for a quick example
• command-line interface ("beta"):
  • beta -f file1 file2 ...: test provided files
  • beta -d dir: test all Python scripts within directory (non-recursive)
  • beta -r dir: recursively test all Python scripts within directory
• functions can be used as normal even after being decorated
• allow assert against exceptions
• trace will point out file --> function --> test case
• can test against itself! cd into source code, run beta -f beta.py

API:

• available test calls:
  • @Beta(4, 5) -- assert output == 5 when input == 4
  • @Beta(4, assertRaises(Exception, msg = None)) -- assert Exception will be raised with message msg when input == 4

Todo | bug fixes

• make ./beta.py a proper command beta
• multiple decorators, all function names except last are shown as "wrapped_f"
• cannot handle function with no arguments
• better assert message
• ~~handle relative paths import (both non-recursive and recursive) ~~
• test all cases, report #success, #failure (follow python unittest output)
• avoid testing beta.py when testing other files
• how to catch raised exceptions?
• more assert methods
• support json input/output files?
• clean import namespace after each file?
