A two-day testing challenge was held for development teams to test software. Teams of two members each selected user stories to test that they did not develop themselves. They presented the stories they chose on day one and the findings from testing on day two. Over the two days, teams found and fixed 44 defects through functional and regression testing, with more than 20 defects fixed before day two began. The goal was for teams to find and fix the most defects over the two days of testing.
