In the process of software testing , You will find some errors in the software , however , The occurrence of this kind of mistake is just a kind of appearance , What exactly caused the error , Which code caused it , These problems need debugging to determine .

Software debugging method

Software debugging generally includes the following methods ：

• Brute force method ： according to “ Let the computer find the error by itself ” Thought , Perform memory mapping , Activate runtime tracing . The method is inefficient , Time consuming .
• backtracking ： Manually follow the control process back from the error , Until the root cause of the error is found . Complex programs have many backtracking paths , Difficult to implement .
• Cause exclusion ： Through deduction and induction , And dichotomy implementation .

The comparison between software testing and software debugging is shown in the following table ：
