Enterprise Testing Methodology And Case Study

Software testing (ST) is a very important part of software engineering. Its target is to find out more bugs in the software to the best of our abilities before the software comes into the productive course. So at the present time, software testing is a key step to guarantee the software quality. It is a final reexamine for the specification description, design and coding. Software testing is concerned with two phases in the software life cycle. Generally, in the unit testing, it is the same person to coding and testing. After this phase, we will put up integrated testing to software system, including competitive testing, system testing, competitive and system testing, customer acceptance testing and etc.Under the instructions of IBM advisors,according to the PDM development experience,the company introduces a set of effective structured testing execution package(STEP), which is concerned by the structured testing and instructed by testing work of subsequent project and achieves biggish profit.The optical transport equipments of the company, its SONET series productions include about 30 functional modules. They provide the foundation of media layer and platform which is the base of information transport and communication realization. BLSR is a kind of link protection, which is the most important protective way in SONET.Consequently, BLSR is a protection mode that formerly traffic can continue to transport and will not have an interruption at BLSR module. Software testing has different missions: at SVT we put up basic function testing, at SIT we put up pressure and coupling testing, at SDV we put up stability and interconnect testing. In the edition interval, we will have a testing construction, autoimmunization script execution and test case amendment.
