I don’t know how you write the parameter verification of the controller layer in your usual business development process? Is there such a direct judgment as below? public String add(UserVO userVO) {<!– –> if(userVO.getAge() == null){<!– –> return “Age cannot be empty”; } if(userVO.getAge() > 120){<!– –> return “Age cannot exceed 120”; } if(userVO.getName().isEmpty()){<!– –> […]

Automated testing–verify email content
Scene There are many scenarios for sending emails in business. The emails are basically sent automatically, and the content of the email is very important. Whether the email is sent or not, and whether the sending time is correct, the workload of each regression test is too large. So consider adding this part to automated […]
21.10 Python uses CRC32 to verify files
CRC file check is a method used to verify file integrity by calculating the file’s CRC value and comparing it with a pre-calculated CRC check value. Whether files have changed, this function can be used to verify whether files in a directory have changed. If changes have occurred, we can print out the changes. This […]
