Stub for

To explore the concepts of functional testing using python and python testing frameworks, I’m building a project to test, on github.

In this post, I’m discussing the stub implementation that I will use to set up the testing frameworks.

I’ve got my requirements written.
An initial set, at least. Enough to get me started.

I want to move on to explore testing frameworks and testing strategy.

But to do that, it will be helpful to have something to test. So I’m going to write a stub for my script. Something that has the right name and interface. I can use it just as I will use the completed script. It just doesn’t work yet.

What’s the stub have to do:

  • be a callable command line script
  • accept input through stdin
  • accept a file name argument
  • print at least something to stdout

That’s really it.
Now I can use this stub to look at test frameworks and start writing tests.

So here is a reasonable stub.

I will go ahead and check this in to version control.

Next, a look at frameworks.

Normally, I’d already have a test framework chosen.
But that’s kind of the point of this blog. At least to some extent.

I’ll take a look at pytest, nose, and the built-in python unittest.

I know doctest is also available and built-in. However, I don’t think I’ll look at it for a general purpose functional test framework. This may be shortsighted. Please let me know if you think leaving it out is a mistake.

Please leave a comment or contact me otherwise if there is some other framework I really ought not to forget.
