Chapter 6. Test Management/Reporting System

In Chapter 3, you learned how to access a database to store and retrieve structured data for use in a Python script, but what about situations where a database is overkill? It is precisely for these kinds of situations that XML exists, and Python is brimming with features to enable you to write to, query, and otherwise manipulate XML.

The test management and reporting system in this chapter shows how you can use XML to store and retrieve structured data in a Python script.

The application will perform the following functions:

Enable a user to run tests and report on the pass or fail results of the tests
Enable a user to list the test runs, by date
Enable a user to show test run results for any previous test run
Enable a user to output the results of any completed test run to an HTML file, so that results can be viewed in a web browser

Using the Program

You can get to the program by navigating to the directory corresponding to this chapter. As in the previous chapters, the files are available for download from www.wrox.com. To run the application, simply go to a command prompt, and from the directory on your system where the Chapter 6 program files are located, type ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
