alib 0.0.1

A LIB-rary of useful Python code

Alib provides simple testing without boilerplate. For example, if myfile.py contains the line:

7 * 8 == 54  # I'm not sure about this!

then running:

$ python -m alib.test myfile.py

will, because the test fails, report the test line and the nature of the failure:

line 3:  7 * 8 == 54  # I'm not sure about this!
(['Eq'], [ReturnValue(56), ReturnValue(54)])

Exceptions are caught. The input line:

(1 + '2') == 3  # Can we add a string to a number?

produces:

line 4:  (1 + '2') == 3  # Can we add a string to a number?
(['Eq'], [ExceptionInstance(TypeError), ReturnValue(3)]

This test line succeeds (because the left hand side raises the right hand side).:

(1 + '2') ** TypeError  # We can't add a string to a number.

To test all Python files in the folder path/to/mydir run the command:

$ python -m alib.test path/to/mydir
