Senior coder to win software testing just master these two methods
Posted by Ottesen Li on February 7th, 2021Absrtact: computer software testing is a critical link in software engineering, this paper will elaborate the related understanding of computer software testing from the goal of software testing, white box testing and black box testing and their specific classification. Finding defects in the tested object as early as possible must be the most frequently mentioned testing goal in the testing process, and also a significant embodiment of the alleged testing value. The objective of finding defects is to promote developers to find and fix problems. Testers can make sure that developers have fixed defects by retesting and regression testing, and don't affect the initial normal area, to be able to improve product quality. Atlanta divorce attorneys stage of the development life cycle, there should be testing participation, and try to look for as much defects as possible, so as to greatly increase the capability to contain defects in this stage, to be able to improve the efficiency of testing, keep costs down and improve quality. White box test regards the test object as an open box. If the white box test method is employed for dynamic testing, it is crucial to check the interior structure and processing procedure for the application product, which is not necessary to try the function of the application product. The coverage standards of white box test include logical coverage, cyclic coverage and basic road strength test. Logic coverage includes statement coverage, judgment coverage, condition coverage, decision / condition coverage, condition combination coverage and path coverage. White box test is always to know the internal working procedure for the merchandise. It could detect whether the internal action of the product is normal based on the specification through the test. According to the internal structure test procedure of the process, it may inspect every part of the procedureThe main types of white box test are logic drive and base test, which are used mainly for computer software verification. Black box testing may be the testing of pc software based on the specification of the software. This sort of testing doesn't consider the interior operation principle of the software, therefore the software is similar to a black box to the consumer. From the user's perspective, testers can find the defects of the application through various inputs and different outputs of the software, but they don't worry about the specific implementation of this program. (1) Unit testing is to check and verify the tiniest testable unit in computer software. The student module refers to the module that simulates the module under test, and the driver module identifies the superior module that simulates the module under test. The driver module is used to get the test data, start the module under make sure output the results. (2) Integration testing is the next stage of unit testing, this means to assemble the system modules that pass the test into a system or subsystem, and then test them, concentrating on the interface departments of different modules. Integration testing can be used to test whether each unit module can cooperate and operate normally. (3) System testing refers to testing the whole computer software system as a whole, including testing the function, performance and the program and hardware environment when the software runs. DepartmentThe main basis of system testing is the document of system requirements specification. (4) Acceptance testing refers to the testing in the later stage of system testing, that will be mainly predicated on user testing, or with the joint participation of quality assurance personnel such as testers. Additionally it is the last process for the program to be formally paid to users. Acceptance testing could be divided into A-test and beta test. A-test refers to the interior test jointly participated by users, testers and developers, while beta test refers to the general public test following the internal test, that's, the test is totally paid to the end user. (1) Function testing is one aspect of black box testing, which checks whether the function of the actual software meets the needs of users. Including logic function testing UI testing UI = interface usability testing: it refers to checking the application system from the perspective of rationality and capability of pc software use, to be able to find out the inconvenient parts in the application. Compatibility testing: including hardware compatibility testing and computer software compatibility testing (2) performance testing software performance mainly includes time performance and space performanceThere are two types of time performance: time performance: mainly identifies the response time of a particular transaction of software. Space performance: mainly identifies the machine resources consumed by the program running. Software performance test may be divided in to: general performance test: it identifies the performance test that enables the tested system to perform in the conventional pc software and hardware environment with no pressure. Stability testing, also called reliability testing, refers to the continuous operation of the system under test to check on the stability of the machine. Load testing: it's to check the stability of the device by making the machine under test run continuously within the limit of the pressure it could bear. Stress testing: it refers to continuously increasing pressure on the system under test before system under test is crushed. It is used to test the maximum pressure that the system can withstand. (validate the device or software enables the biggest stress. ). Interface testing is mainly used to detect the interaction points between external systems and internal subsystems. The focus of the test is to check the info exchange, transfer and control management process, plus the phase of the systemMutual logical dependence etc. Recommend an interface make sure interface document production tool: apipost regression testing refers to the employment case of over repeatedly executing the previous version test when testing a new version of computer software. (when a fresh build or release is deployed, repeat all of the test cases that has been executed within the last build or release. ) smoke testing identifies verifying if the basic functions of the application are realized and whether it has testability before large-scale testing of a new version. (validate the major function is deployed or not in pc software of system each time a new build or release is implementation. ) random testing ensures that most of the input data in the test are randomly generated. Its purpose is always to simulate the true operation of users in order to find some marginal errors. (means or all of the test data is ranDom, to validate the some edge bugs. ) this article is shared from Huawei cloud community "software testing methods", original author: Ben Si Dunong. aws certification visit site
