Recently I wrote a post about how our team used a mind map to help us with theme planning. We also sometimes use mind maps to help us in planning our testing. Some people asked if I’d post an example. Here it is:

Theme Testing Mind Map

We’re a financial services company, and this theme was a rewrite of one of the oldest and most critical parts of our system: sweeping a tiny percentage of the assets in each participant’s account as pay for our services.
My fellow tester Lori Thayer (who came up with the idea to mind map test cases) and I wrote the initial mind map, then discussed it with the rest of the development team, the product owner, the controller and other stakeholders. Our central node is “Run”, because this is a batch process that needs a way to be kicked off, make sure prerequisites are in place, provide a way to monitor progress, and be restartable in case of problems. Not only is it important to test these parts of the system, but they’ll be invaluable to help us execute and monitor tests.
Without boring you with all the details of this them, you can see that the map includes some primary nodes such as “collection” for sweeping shares out of the account, “sale” for selling the shares once they’re in our company account (definitely in our best interest!), and “instructions”, each representing one participant’s account. We drew dotted lines between related nodes, such as “collection” and “sale”, “sale” and “fast401k account”. The map includes details such as the internal account number where the funds should end up. On the right side, we wrote questions that nobody was able to answer yet. These got answered as we learned more through talking to stakeholders and doing exploratory testing on a design spike.
We referred to this map many times over the next several iterations as we implemented this theme. We checked off the areas that were tested, added more questions and/or answers, even added more nodes as we thought of more areas to test. We didn’t get down into level of test case detail, but the map shows the relationships we needed to test, in addition to the individual components. (Unfortunately, I neglected to take an “after” photo).
We got into more details on the team wiki, using color-coding to show questions and answers. Our most senior programmer lives in India, and the wiki is a good way for him to participate in discussions like this.

Here’s a snippet of some test scenarios we wrote. When we’re satisfied with a test, we put our initials next to it to indicate it’s done.

Example Test Scenarios

It took us five iterations (ten weeks total) to finish this theme. At the end, we felt confident that we’d thought of and discussed all angles of the process, its potential impacts on other parts of the system, talked to all stakeholders about their individual needs and concerns, and done adequate testing not only at the functional level, but also performance and usability.
