Load Testing is Not an Academic Problem

For Rowan University, ensuring that their students can get registered for classes is not an academic problem. If errors or system crashes prevent students from getting into the classes they need, it can have a serious impact on their academic careers, potentially even resulting in additional educational costs. So when the IT wizards at Rowan were planning significant upgrades to their hardware and the Banner 9 software from Ellucian to ensure the best possible experience for their students, they knew load testing was an essential part of the project.

We have completed work on an improved version for our next release (3.6).

Of course, you can still specify a global page performance goal, as you could in the past. In addition, users can specify a default page (or transaction) duration goal for an entire testcase and then override that value for each page or transaction. The performance … Continue reading »
