Because the software programmer in the error and the operator in the use of errors will be the application of such problems. Therefore, we must be familiar with the types and classifications of program errors, so that we can solve these errors, our program is more perfect.
Error authentication is the process of determining what errors lead to failure, error correcting, or purging is the process of modifying the system to remove errors. Errors in calculation and precision occur in the execution of the formula or without the need to calculate the desired precision result. When the document and the program do not actually match, common errors have documentation errors. Overload error. Jongcay, edge errors, clock and coordination errors, throughput or performance errors, recovery errors, hardware and system software errors, standards, and program errors.
Software tests are divided into module tests, component tests, or unit tests. Integration testing is a process that ensures that the components of the system work together according to the system description and design requirements. Functional testing evaluates whether a system can implement the functionality described in the requirements analysis as a complete system. The result is a functional system.
Check code is divided into code pre-line, code review, successful code review, and finally to prove the correctness of the code, a program, there must be good and bad, so we also need a specific method to prove his bad.
