1. Identify what the correct behavior looks like Customers (or QA) do not mention all bugs. Some problems may be caused by their incomprehension of the software. In this case, you need to check the relevant documents of the software (if any). For example, you need documents because the software is implemented as needed. If not, it is a bug.

-related information, such as file path, many times delete the file path, timestamp and other information, you can search results . If the results are still not found, and log has a more definite meaning, then we can directly analyze the meaning of log, determine the cause of the problem . For example, in another article that was encountered error: 不兼容的类型: java.util.List , it is certainly irrelevant to take this error message, because it is too short and too

Writing code to this world is not a single person, but a team (such a large project cannot be developed by one person ). And seriously suspect this open-source project. Developers are considered to be gods, so the theory of God is incorrect. The theory of God is the truth, and mortals have the opportunity to become gods, until your divine attribute breaks through a certain level ).
