Smalltalk Report, October, 1994
Published online by Cambridge University Press: 04 August 2010
This was the column that generated the most interest and email for me, all of it positive. Other than that, there's not much to say, except “Get to work writing tests—yeah, you, the Smalltalk hacker.”
You can't argue with inspiration (or deadlines). I started to write the final column in the sequence about using patterns for design, but what came out was this. It describes some work I have been doing with a framework that takes the tedium out of writing tests. I'll get back to the pattern stuff in the next issue.
Smalltalk has suffered because it lacks a testing culture. This column describes a simple testing strategy and a framework to support it. The testing strategy and framework are not intended to be complete solutions, but, rather, are intended to be starting points from which industrial strength tools and procedures can be constructed.
The article is divided into four sections:
Philosophy. Describes the philosophy of writing and running tests embodied by the framework. Read this section for general background.
Framework. A literate program version of the testing framework. Read this for in-depth knowledge of how the framework operates.
Example. An example of using the testing framework to test part of the methods in Set.
Cookbook. A simple cookbook for writing your own tests.
