In my scrum team, the stories are not breaking up correctly. For example, one feature needs to be built, the team, divided into 2 parts, 13 and 8 pointers each, testing efforts are outside this. and assigned to 1 person. I am currently on my 7th day of the sprint, it is due to get pushed to QA by tomorrow EOD, I am unable to track the progress daily. My burn down chart looks like a straight line.
