When we generate our reports, Test Studio will only indicate to us the number of test cases that were executed. 

The problem here is when we use data driven testing, the number of scenarios executed can be much higher than the number of test cases. For example, if we have 10 test cases in our list, but each test case runs through 10 iterations, Test Studio will only report that 10 test cases have been run, not the 100 iterations. 

This makes getting an accurate report of our testing very difficult. If one iteration fails inside a test case, then the entire test case is considered a failure.
