Method of testing and description
System testing is through the whole process of system definition and exploitation.Resulting documents of each stage such as demand analysis, summary design, detailed design and program coding comprise requirements specification, summary design specification, system design specification and source program, all should become the object of software test.
For holding the correctness of each link of system development, need carry out various affirmations and checking work.Be confirmed to be series of activities and process, purpose is to want to confirm the logical correctness of system in a given external environment condition.Checking is attempted proof in each stage of system's lifetime, and the logic coordinating between the stage, completeness and correctness.
Native system mainly adopts the method for Black-box Testing to test.
1. functional test.The whether explanation up to specification of the function of its check system.Because correctness is the most important qualitative factor of system, so its test is also important.
Another kind of effectively method of testing is the boundary value test, promptly adopts field of definition or section boundaries value of equal value to test.The possibility of makeing mistakes when noting just equaling, be greater than or less than definite fiducial value in data stream, the control stream.To carefully select test case to these places, conscientiously be tested.If module is had requirement working time, also to carry out critical path test specially, to determine influencing the module factor of working time under the worst case and under the average meaning.Because the programmer neglects border condition easily, and program is made mistakes through the boundary value place that is everlasting.
2. fault-tolerance test
The fault-tolerance test is the behavior of check system under exception condition.The system of zmodem can guarantee that the accident that can't expect does not take place in system.Fault-tolerance test some irrational inputs of structure usually lures software to make mistakes, for example: input erroneous data type, the numerical value outside the input field of definition.
3. performance and efficiency test
Performance and efficiency test mainly are the travelling speed of test macro and to the utilization factor of resource.Sometimes people are concerned about test " absolute value ", are how many bits of per second as the data transfer rate.Sometimes people are concerned about test " relative value ", as certain system than another system fast what doubly.
When obtaining " absolute value " of test, we will take into full account and write down the influence of running environment to test.When obtaining " relative value " of test, we will guarantee that tested several running softwares are on all four environment.
Very important one is limit test in performance and the efficiency test, because a lot of software systems can be collapsed in limit test, promptly ceaselessly send out request continuously to server, whether testing server can be absorbed in deadlock state be can not extricate oneself, import king-sized data to program, look at whether it is able to stand.
