Get the number of passed/failed tests in the code

I would like to use GoogleTest for automatic grading of homework assignments. For this, I need to get the number of passed tests and the number of failed tests in the code, so that I can write, at the end of the main testing program, something like: "grade = passed*100/(passed + failed)". I do not need to print a report - I will later insert this grade into a database. Is it possible?
