The Research And Building Of Improved V Model In Embedded Software Testing

Software testing model is the theoretical model that used to guide how to carry out the process of software testing. This article has been improved the return testing to improve the test model, increase the arrows that from all the testing phases to unit testing, The scope of return testing from the unit testing to ensure that change the original error and the new error avoidance. In the improving test model to identify the various testing activities in parallel, allowing all the testing phase of adjacent, or even non-adjacent overlap between the testing phase.The requirement changes as a starting point to improve the test model, analyzing the type and causes. Introducing the UML, XP and TDD technology into embedded software testing, UML able to clearly describe user'needs and requirement changes, XP and TDD's "test first" can be highly effective solution to the requirement changes. In this paper, the specific examples introduced to assess the improved test model.
