checkexpect is a simple unit testing framework for python development
checkexpect is a simple unit testing framework for python development https://pypi.python.org/pypi/checkexpect in a python library. checkexpect is a mature, viable way to make your test-driven development drive the design of your data, and your data drive the design of your functions. It’s also a simple tool that allows you to execute unit tests inline with your code, in a systematic way.
This is a fork of the original checkexpect, hosted on GitHub and last updated in 2016.
- [x] Support for inline unit tests. checkExpect will support tests created in another directory as well.
- [x] Support for TDD and DDD development.
- [x] Support for Systematic Program Design methods using HtDD and HtDF recipes.
- [x] Support for color coded terminal (console) output.
- [ ] Python 3.5 support.
pip install checkexpect
Now you can now add a reference to the checkexpect package like so.
#!/usr/bin/env python # import package from checkexpect.core import checkExpect
Write some code and test it using checkexpect inline with your code.
#!/usr/bin/env python # import packages from checkexpect.core import checkExpect import math # Usage: checkExpect(function|object|type, param, expected value, "a description of the test") # define a function def square(a): return a * a # could replace return statement with (lambda a: math.pow(a, 2)) # from code_statement_B below. # examples num_to_square = 12 code_statement_A = 12 * 12 # used in the function body # check the algor1thm design of our square function, and unit test it at the same time checkExpect(square, 12, 144, "Square of a number") # Or just pass our examples checkExpect(square, num_to_square, code_statement_A, "Square of a number") # Or use lambda expressions code_statement_B = lambda a: math.pow(a, 2) checkExpect(square, num_to_square, code_statement_B(12), "Square of a number") # add up a list of numbers # examples param1 = [1,2,9] def add(args): total = 0 for i in args: total = i + total return total checkExpect(add, param1, 12, "Add two numbers") # Create a string from an arbitrary list of strings # examples param3 = [ "Darel", "Johnson"] def string_together(los): newStr = [ str.strip() for str in los] return " ".join(newStr) checkExpect(string_together, param3,"Darel Johnson")
Execute your python script from the command line (terminal) to see the unit test results. Most tests usually fail (RED) in the beginning.
Refactor your code and execute your script until all functions under test, turn GREEN.
That’s it! You’re done.
pip install checkexpect -U
That command will upgrade an existing installation of checkexpect.
None - No configuration needed.
