The dream of a milk cow is to become the most popular cow in the herd, that is, to be welcomed by all other cows. "Welcome" is a transmission, that is, if Niu A thinks that Niu B is popular and Niu B thinks that Niu C is popular, Niu A also implicitly thinks that Niu C is popul
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. When using black-box test method for dynamic testing, the function of software product needs to be tested. There is no need to test the internal structure and process of software products.The test case methods designed with blac
?)After the vision is established, we can start to identify and organize the needs. Use Cases are an effective means of expressing requirements. They help or even force us to think about problems from the user's perspective, so that the needs truly reflect the value to users. The use case itself provides a formal expression specification, which reflects the organizational level of the requirement:In this form, all requirements are organized around us
Interface testing is a part of project testing. Just like its name, it tests interfaces and tests interfaces between system components. Interface testing is mainly used to detect the interaction between the external system and the tested system and between the internal systems. The focus of the test is to check the data interaction, transfer, and control of the management process and the dependency between systems.
How to design an interface test case?First, clarify the starting point. Like all

I. Steps for designing a test case using the causal method:1. analyze the software specification to describe the cause (that is, the equivalence class of the input condition or input condition) and the result (that is, the output condition), and assign an identifier to each reason and result.2. Analyze the semantics in the description of the Software specification, find out the relationship between the cause and the result, and between

ObjectiveSuppose you execute a script (. py) use case for a minute, then 100 scripts take 100 minutes, and when your use case reaches 1000, it takes 1000 minutes, or 16 hours ...How can you save time by running multiple. py scripts in parallel? This is the use of multi-threaded, theoretically open 2 threads time to save half, open 5 threads, time is shortened by five times times.Project structure1.
