Research Of Auto Test On The SDH Transmission Network

With the constant enlargement of the software scale, thecomplexity of software design is improving constantly, the chance of themistake or defect appears to get more and more in softwaredevelopment. Meanwhile, the understanding of quality importance ofthe software of market is strengthened gradually. So, the importance inproject implementation of software of software test is outstanding dayby day. The main research contents in the article are divided into fourparts: Relevant knowledge introductions tested in software test andautomation;Only transmit group's network of network (SDH ) and testthat analyzes testably;NE key technological analysis of artificialplatform and application while testing in automation;Concreteapplication that tested.Ever a master has said: The software test purpose lies in findingthe mistake;a good test lies in finding the mistake that has been neverfound in the past with the example;a successful test is to find that it iswrong to never find in the past. Software test occupies very importantposition in whole software development as the important means thatquality ensures of the software. A large number of statistics indicatesoftware test work load account for software development total 40 workloads often? Fragment With change, take the place of typepopularization to develop course, test extensive applicationautomatically, it can finish testing the unable realizing or test difficult torealize by more hand. The correct and rational automatic test ofimplementation, can improve software quality, save the funds, shortenthe products and release cycle.It is tested that automation is a kind of test technology, through testusing automation software according to mechanism that establish ,automatic to examine system carry out a kind of technology tested.More precise and speech, it is tested that automation is not "tested"technology is a kind of technology of " testing again ", used mainly fortesting. It is tested that the automatic goal is the automatic test to becarried on by the test system. Generally speaking, it is tested that theautomatic goal is to obtain more thorough test through less expenses,improve the quality of the products.SDH full name is synchronous digital system (Synchronous DigitalHierarchy);city land key supporting network of transmission net, itsapparatus stability is important and self-evident. In the face of the fiercetelecommunication market competition, the apparatus supplier has tolook for a certain equilibrium between quality and pace. System testingis to research and develop the test which the simulation users of theproducts use in the system, content various, by done by hand to go on ,test , catch up with products paces of demand more and more mainly allthe time. So the research tested in automation is imperative, and needto become effective fast.Only transmit the network group's network and test that can bedivided into: Network management interface test, network pipe NE ofinterface test, NE of system testing of management, introduce networkpipe NE of interface test mainly in the article. What is called networkpipe NE of interface test, test network management and networkinteraction of NE according to interface file mainly. The interactionoccupies very important position in the network of transmitting of light, ifthe interface goes wrong, will cause the taking off and is in charge ofthe phenomenon of the whole network, the consequence is veryserious. Interface file come, make, finish by sector standard accordingto communication, all rule to follow needed , manufacturer ofcommunication ,, if only the interface communication between thenetwork management and apparatus of our company is normal,represent products qualified , such apparatus will appear unablecompatible phenomenon in many manufacturer cooperation in thefuture. So test, want test according to the interface file totally ininterface communication.Interface test can divide into network management test and NE testtwo part, network management test i.e. network managementnewspaper exactness that document issue test , NE test it is NE ofsystem that deal with newspaper gentle exactness and treatmentfunction test. SDH apparatus that company produce, and networkmanagement systematic communication way to come, finish accordingto TCP/IP agreement, according to the agreement, can design onenetwork management artificial platform come intercepting newspaperarticle that the two take place each other test. Contrast interface file,prove newspaper gentle exactness, do it in this way, realize interfacemutual test of exactness. Simulation newspaper gentle to carry on greatdata quantity issue to NE, observe the handling capacity of NE of thenetwork, can realize NE of management device test of performance.Gentle to every newspaper issued, the operation of the networkmanagement is usually complicated, and make and transmit the gentlecondition to change to some extent, the smiling change that will causethe newspaper to be gentle, it is very difficult to test like this. In order tosolve this problem, we have put forward a new artificial method,artificial platform of the network management. The artificial platformuses the artificial network management, the newspaper documentcarrying on the quantity of big data the apparatus is issued, can comestructure to be newspaper gentle , make fashionable test tactics come ,divide piece to issue time according to the needs of one's own one. It isgentle to keep the each test newspaper , is used for continuing the testnext time , has realized the automation that is tested, test , offerfavorable terms for group network , offer effective means directly for thefact that the tester carries on the performance of group's network , testof stability and communication ability .The main thinking of the test platform of the network managementis to separate the network management and network apparatus ofgroup, achieve the goal of testing to NE alone. Through setting upessential check point, set up and measure the pass way, thereforeproduce the correct template storehouse. In combine test , withhardware apparatus that upgrade network management edition thatupgrade, through the same operation, the data produced compare withdata of the template storehouse, can look for the question that thesingle-board software upgraded appear directly , thus improve theefficiency of system testing , save the human resources .Combine the whole framework of designing artificial platform of theactual conditions in the article, and has carried on key technologicalanalysis to the realization of the artificial platform. First of all, analyzeQx interface characteristic, analyze the newspaper documentaccording to the code principle of Qx interface with gentle newspaper,and analyze the implementation method in simple introduction.Secondly, in come back, need some functions that realize test, artificialplatform, for example automatic execution that tests by the automaticsave of the example, compares, etcLast part in the article, combine actual conditions discuss, test untildesign, test of example with management of example, and come backexecution that test. It is numerous that test uses the example designmethod, consider the work load of exhausting the law is too large,unable to finish place enable us choose a part among them as and testthe example of using in the possible data actually, the most commonequivalence division law and border value law are suitable for mostoccasions, can use the example choice method as testing. Test thatcan be realized in the artificial platform by the management of theexample, can utilize existing management software too. Testmanagerone good administrative system, detailed introduction office procedureand advantage its in the article. Finally in come back test, introducingmethod, return tested to come back test tactics make, return to resultanalyze and test conclusion, etcThis kind of method of testing has already been used in the realwork, and has reached very good result, have found a lot of troublesproduced while revising. This kind of method of testing that has themodel for the first time is in the exploration of the future method oftesting, there is broad promotion space.
