There are now about 280 projects which raise more than 300,000 test cases, 350,000 test sets, and some 400,000 test runs.

Lyall said there are a few challenges for the future, including treating test tools as production applications in the organization.

"We're getting more formal with how they are treated [and] more formal capacity planning and monitoring," he said. "We also want more formal SLAs (service level agreements) that define to our users what to expect."

The bank doesn't have the dashboard implemented yet, but is writing perl scripts and excel macros to generate reports. The business process testing module is also yet to be done.

Lyall's colleague Lin Sun said the benefits of a migration approach was that downtime was minimized.
