The "soft testing basics" software test is a key step in the software development process and aims to ensure that the software meets the desired quality standards. The basics of software testing are basic theoretical knowledge of software testing, covering basic concepts of software testing, software testing models, software testing methods and test tool profiles. ** definition of software testing** definition of software testing is one of the basic concepts of software testing. Software testing can be defined as a final review of software needs analysis, design specifications and coding before software is operational and is a key step in software quality assurance. The process of running the software is defined earlier as the purpose of the software test to detect errors in the software. The later definition considers software testing to be a process by which a system is operated or measured using manual or automated means to test whether it meets the required needs or to ascertain the difference between the expected and the actual operating results. ** the purpose of the software test** is one of the basic concepts of the software test. There are two authoritative definitions of the purpose of software testing: to evaluate the characteristics or capabilities of a programme and system and to determine whether it has achieved the desired results; and to identify potential errors and deficiencies in the software at a minimum of time and manpower before the software is distributed to end-users. The purpose of the software test is to test whether the software meets the required requirements or to ascertain the difference between the expected and the actual operational results. ** software testing principles** software testing principles are the basic principles of software testing. The principles for software testing include that all testing standards are based on user needs; that quality standards for good products are defined as early as possible; that testing should involve early intervention; that exhaustive testing is not possible; that testing should span the entire life cycle of the software; and that there should be a third party or independent testing team. **software test classification**software test classification is one of the basic concepts of software testing. Software tests can be divided into unit tests, integration tests, system tests and acceptance tests according to the development phase. The module testing is the correctness test of the basic modules of the software, the examination of errors in code grammatics, format and logic, the verification of the program's conformity with norms and the early detection of possible deficiencies within the modules. An integration test is a unit test for defects in integration, a logical extension of the unit test and an issue that arises when the combination unit is tested. ** the software test model** is one of the basic concepts of software testing. Software test models include black box tests, white box tests and grey box tests. The black box tests observe the behaviour of the software from the outside, check whether the software meets the requirements and check whether the software is correctly entered and exported. The white box test is to check the internal structure of the software, check whether the software is logical and check whether the software code is standard. The grey box test is a combination of black box testing and white box testing to check the internal structure and external behaviour of the software. ** the software test method** is one of the basic concepts of software testing. Software testing methods include equivalent partitioning, boundary value analysis, state migration testing, case testing, exploratory testing, etc. Equivalent partitions are divided into several sections of the software input data, each with representative input values. Boundary values are analysed to check whether the software's boundary values are correct. The status migration test is to check the correct state of the software. The use test is to check whether the software is used correctly. The exploratory test is to check the soundness of the software. ** the test tool brief** is a supporting tool for software testing. Testing tools can help testers to conduct software tests more easily and quickly. Test tools include junit, testng, selenium, appium, etc. Junit is a unit testing framework in java. Testng is a test framework that provides many useful features. Selenium is an automated testing tool for the web application. Appium is an automated testing tool for mobile applications。
