Hello I was wondering how to test a class in python is it the same way
as
testing a function ?
Depending on the design of the class, there might be a little bit more
set-up involved. But the ideas are similar.
In a test case for a function, we have a few things in hand:
1. The function being tested.
2. The parameters we're going to pass as inputs to that function.
3. The expected output we want to see if the function is behaving
properly.
In a test case for a class, we have a few more things in hand.
1. The class being tested.
2. The parameters we use to create the class instance.
3. The particular method of the class that we're testing.
4. The parameters we're going to pass as inputs to that method.
5. The expected output we want to see if the method is behaving
properly.
So you can see that the core concept for testing is the same: we
express the things that are going to change, and we also say what the
expected result is supposed to be. It just so happens that classes
can have a lot more state, and this can contribute to a few extra
steps to do the test set up..
I suggest PyUnit for easier testing.
Here is a very good guide: http://pyunit.sourceforge.net/pyunit.html
Quoting from the link "PyUnit forms a part of the Python Standard
Library as of Python version 2.1." so for the latest version see
https://docs.python.org/3/library/unittest.html

what you can do for our language.
