Description
Our black box represents into mitive database. it can save an integer array and has a special I variable. at the initial moment black box is empty and I equals 0. this black boxprocesses a sequence of commands (transactions ). there are two typesOf transactions:
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 needs to find the internal code from the code syntax in the algorithm, overflow, path, condit
In the past few weeks, we have studied black-box testing, which summarizes the black-box tests today.Black box test:

Black box testing is also called function testing, data-driven testing, or specification-based testing. Focus on functional requirements of testing software.Using this test method, the te
Black box testing and Its instances
(1): black box testingBlack box testing refers to testing the functionality of the program, that is, testing the functionality of the program to meet the needs without considering the specific internal implementation. It is equivalent to a
collection.(iii) Causal diagram methodCausality diagram method is also a more commonly used black box test method, is a simplified logic diagram. Causality diagrams can visually indicate the causal relationship between input conditions and output actions, and can help testers focus on input combinations related to program functions.Causality diagram method is a kind of test method, which is suitable for de
Black box Test principle: Known product functional design specifications, can be tested to prove that each of the functions implemented to meet the requirements. The black box test of the software means that the test should be done at the interface of the software. This method is to think of the test object as a
equivalence class (9): NN does not meet the requirements, nn>12

Black box testBlack-Box testing is called functional testing or data testing, when tested, the software is considered as a non-open box, regardless of the internal structure of the program and internal characteristics of the case to test, the main purpose of the black
Black box testOverviewThis method is to see the test object as a black box, the tester does not consider the internal logic structure and internal characteristics of the program, only according to the requirements of the program specification, check the function of the program is consistent with its function descriptio
Because the experiment hasn't been done yet, I can't write the experiment report. Here I will briefly describe several common black-box test methods.Black box testing, also known as functional testing or data-driven testing. is to think of the test object as a black box. Whe

Question:
There is a black box for two operations, one is add to save the number in the box, the other is get to find the number in the box, the default box is alway
: Operator + = to complete the above operations?
The answer is no. I did say that cstring avoids the embarrassment of searching for the end, but cstring brings another embarrassment-the embarrassment of duplicate replication. Cstring: Operator + = in the final analysis, the above cstring: concatcopy is called, And once cstring: concatcopy is called, memcpy is called twice, so cstring :: operator + = is a more cost-effective method.
Whether it is a string processing function of C or a string c

Black box testing test case design methods include: equivalence classification, Boundary Value Division, cause and error analysis,
The white-box test case design methods include statement coverage, decision coverage, condition coverage, decision/condition coverage, and multiple condition coverage.
