The measurement to software testing process is addressed.Software testing is to find software internal problems. It is crucial part of quality assurance. But it is pity that we cannot achieve complete testing due to practical limitations and theoretical impossibility. And just as the old saying "fail to plan, plan to fail",good testing requires thinking out a test plan, defining the responsibilities and tasks during the development of product. They are the essential prerequisites to prepare for and manage the testing in the realworld. Software Metric for software testing is the measurement of quantity that has impact on software testing. This paper makes a brief introduction to software testing measurement and then introduces a practical metric for the schedule and software problems counting in software testing.
