Introduction to Software engineering Tenth chapter

Software Testing

Verification and validation, software errors are objective, so in order to grasp the correctness of the various aspects of the software needs to carry out a variety of validation and verification work.

The basis of software testing first to understand what is software testing, but also to comply with the basic principles of software testing, master software testing and software development of the various stages of the relationship also to test document records.

Software testing strategy to carry out unit Test unit testing the main task is to complete the module interface test, module local data test, module all independent execution path test, module error

Process path test, module boundary condition test. The method of integration test integration test After the module testing has top-down integration, bottom-up integration. Validation tests are also performed, system tests

To ensure that the software through recovery testing, security testing, strength testing, performance testing and so on. Test also with the Software debugging software debugging method has a simple debugging method, inductive method debugging, deduction debugging

Backtracking debugging.

The software testing strategy is described above, and the software test method static test and dynamic test, black box test and white box test are introduced.

In addition to the general software testing methods for object-oriented software testing, first of all to understand the object-oriented test type, mainly model testing, class testing, interactive testing.

A Software performance test tool, LoadRunner, is also presented at the end of this chapter.
