How do you know when to stop testing?
This can be difficult to determine. Many modern software applications are so complex and run in such an interdependent environment that complete testing can never be done. Common factors in deciding when to stop are...
•        Deadlines, e.g. release deadlines, testing deadlines;
•        Test cases completed with certain percentage passed;
•        Test budget has been depleted;
•        Coverage of code, functionality, or requirements reaches a specified point;
•        Bug rate falls below a certain level; or Beta or alpha testing period ends.

Q3：unit test objective include that:all the functions had been tested fully.
quality  measurements to the UT:the rate of logic coverage can be considered as a whole.That means the logic coverage rate should reach a certain level,for eg. 50% or 70%.
Actually,the logic coverage includes statement coverage,decision coverage,path coverage and so on.Different projects have different coverage rate standards,so it's hard to define a clear quality  measurements.
