Boundary Value Analysis is a common black box testing method that supplements the equivalence class division method. The so-called Boundary Value refers to the input and output equivalence classes, some specific situations that are slightly higher than the maximum value or slightly lower than the minimum value. The Boundary Value Analysis Steps include determinin

? If a unit test is performed for specific code implementations, the unit test code that is written will be changed as required, and it needs to be changed frequently, does unit test code cost too much? ? Unit tests should emphasize the intention and interfaces of external users (systems) to write tests and perform so-called black box tests? In this way, the unit test code written will be relatively strong

White box test: It is tested by the source code of the program without using the user interface. This type of test requires the discovery of the internal code from the code syntax in terms of algorithms, overflows, paths, conditions, and so on shortcomings or errors, and then corrected.Black-Box testing: Also known as functional

curriculum score of: Chinese, maths, English. First of all, according to the overall score of individuals ranked, if the total of two people are equal in accordance with their language scores ranked, if the score and language scores want to be the same, then according to their mathematical performance rankings, please use the equivalence class method to rank.Answer: Total, language: Chinese, Math: Math, English: 中文版Valid classes: TA≠TB, ranked by total overall score Ta=tb CA≠CB, ranked by lang

software. What is closely related to the software also requires our software testers to test the software. For example, the product manual is very important. It involves issues such as the customer experience when your software is just put into operation. Do not underestimate the product manual. If you have tested the manual, it can clearly explain your individual abilities. Dynamic black box

of the designed test cases against the program logic and should be supplemented with sufficient test cases if the coverage criteria are not met.If the function description of the program contains the combination of the input conditions, the causal diagram and the decision table-driven method can be selected from the outset.For the software of parameter configuration class, the orthogonal test method is used to select less combination method to achieve the best result.For a system with clear bus

One, black box testNot much to say, first on the definition of black box test: Black box test is also called functional testing, it is tested to detect whether each function can be used

To put it simply, software testing can be divided into two main categories: black-box and white-box testing.White Box testing: It is through the program's source code to test without using the user interface, this type of test nee
