I read a stimulating blog post by Michiel de Mare entitled “Is Your Program Perfect”. The post was essentially a bunch of questions that made you consider whether there were any improvements you could make to a program to make it better. There was a section on testing that asked whether your program could be scripted from the command line. It also inquired whether your program exposes an API. I thought long and hard about these questions as I considered my projects own suite of applications. And I determined they were very weak in this area. The question now is how do we make changes to the programs to improve in these areas.
In the past I had played with WinRunner by Mercury Interactive. This tool pretty much allowed you to automate testing of any Windows application. The tests could be scripted and create easily by recording and playing back user actions. However this required you to purchase the expensive WinRunner tool. Furthermore this tool is going to be retired in a few years. It would be more economical and beneficial for our applications to provide better test and scripting support itself.
Currently one of our applications has an API that allows you to instantiate at least one of its screens programmatically. However it is a very cumbersome API. You have to create a data on the file system or in shared memory. It also requires clunky windows messages to initiate the actions. This support only exists in one of the five applications in our suite. And this support is for one very specialized part of the app. It would be great if a more comprehensive and simple API could be produce to control the application for test purposes. I envision this to be of great use during the unit test phase.
Obviously it will take a while to add the hooks to our applications. But we could start small and work our way up from there. Perhaps the best place to start would be to automate access to the new feature we are currently coding into the application. We should be very familiar with the design and implementation of the new code. And we already have time in the schedule to work on these pieces. During the unit test phase of these features we could add in the automated support and actually use it for unit testing.
All of this introspection was due to a small piece of Michiel’s blog post to question whether your software is at its best. Opening our apps up to automation may go a long way to simplifying our unit test strategy.
