2, measurement edit, software reliability is measured in terms of mean time between failures (mtbf).
Here one checks how the software works in its relevant operational environment.
Life testing of the product should always be done after the design part is finished or at least the complete design is finalized.There may be some critical runs in the software which are not handled by any existing test case.7 Importance of reliability testing edit The application of computer software has crossed into many different fields, with software being an tempat game perang pc essential part of industrial, commercial and military systems.A Statistical Basis for Software Reliability Assessment.Such type of simulation is observed in some industries like nuclear industries, in aircraft etc.Mean Time Between Failure(mtbf)Mean Time To Failure(mttf) Mean Time To Repair(mttr).

The distribution of test cases should match the actual or planned operational profile of the software.
