Now there are many test automation tools. Choosing reasonable and correct automated software testing tools plays an important role in saving testing costs, shortening testing cycle, improving testing efficiency and improving software quality. How to choose a reasonable and correct test automation tool should be considered from the following aspects:
1. Whether the functional function of automated software testing tools is powerful or not is an important reference factor in selecting automated software testing tools. Automated software testing tools not only need to have the basic functions of software testing but also need to have: integration function, recording and playback function, image testing function.
2. Automated software testing tools must adapt to the software life cycle. The purpose of software testing varies with the software life cycle, so the life cycle of the software should be fully considered when selecting automated software testing tools. According to different stages of software life cycle, select the test software that meets the actual requirements.
3. Automated software testing tools must have consistency and continuity.
Software testing has a core position in the field of software engineering technology and methods. it is the guarantee of software quality and software reliability, and the guarantee that software can run correctly and effectively. Traditional manual testing methods have been unable to meet the actual needs of software testing with the rapid development of programming languages and the increasing scale of software systems, so automated software testing tools have been widely used. Automated software testing tools can reduce the workload of software testing, reduce the cost of software testing, shorten the time spent on software testing, and improve the efficiency of software testing. However, not all automated software testing tools can be applied at any time. They should be selected according to the characteristics and main uses of automated software testing tools and the different types of software systems to be tested. The commonly used automated software testing tools mainly include: network testing tools, functional testing tools, load stress functional testing, white box testing tools, test management tools.
The network testing tool is composed of network simulation tools, network positioning tools and network performance testing tools. the evaluation method of this kind of automated software testing tool is mainly to analyze the distributed application performance of the software. test the interactive activities within the network, applications, and other elements, so that operators can clearly and fully grasp the application behavior of different network activities and different locations. The network testing tool can observe and evaluate the application behavior of the software at the code level and application level, that is to say, the network testing tool can not only evaluate and test the internal structure of the code, but also evaluate and test the network conversation behavior of the network application, and parse all the problematic network conversations.
The functional testing tool will compare the user's operation record with the pre-set standard through recording, playback, detection and evaluation of the software user's operation. it has been tested whether the function of the software can operate normally and whether the function of the software can meet expectations, and the reasonable and correct use of functional testing tools can greatly reduce the workload of black box testing. Reasonable and correct use of functional testing tools can also effectively perform regression testing in the iterative development phase.
The load stress testing tool tests the software with the performance and scalability of the software as the evaluation objective. the load stress testing tool evaluates the critical business of the system by simulating n users. real-time monitoring is used to find and confirm the problems of the application system, and then to successfully deploy the application, we must formulate the corresponding optimization strategy according to the actual problems of search and confirmation. Reasonable use of load stress testing tools to evaluate and test the overall architecture of the application software can optimize the performance of the application software and shorten the testing cycle.
The main function of the white box testing tool is to test the code of the software, effectively locate the defective code segments in the testing process, and then repair the defective code segments. According to the working principle, white-box testing tools can be divided into dynamic testing tools and static testing tools. The static testing tool does not need to run the code during the testing process, but directly scans the code syntax to check whether the code matches the coding specification; the running principle of the dynamic testing tool is to insert part of the monitoring code into the executable file to evaluate and test and to count the data of the running phase of the application software to check whether the code syntax matches the coding specification. The biggest difference between static testing tools and dynamic testing tools is that the former does not need the actual operation of the application software in the testing phase, while the latter must actually run the application software in the testing phase.
