List of common bugs in software testing

Software testing ,bug There are many types of , such as ： Code error 、 Interface optimization 、 Design flaws 、 Demand supplement and user experience ;

In general , It's easy to distinguish between demand supplement and design defect , But the code is wrong 、 The distinction between interface optimization and user experience is not obvious ;

Now let's talk about these three , By the way, sort out some common types bug example .

Code error

Code errors are easy to understand , In a nutshell , When programmers design works , The programming code created and written is wrong , For example, methods 、 Function, etc. , Unable to achieve the required functions or achieve the wrong functions .

Examples are as follows ：

1、 When operating or using a function , Cause the program to exit abnormally , Or other functions cannot be used , Or cause frequent crash and restart ;

2、 Memory leak ;

3、 Loss or destruction of user data ;

4、 System crash 、 crash 、 frozen ;

5、 The program or module cannot start normally or exit abnormally ;

6、 Serious numerical error ;

7、 The functional design is seriously inconsistent with the requirements ;

8、 Errors that make other functions unusable ;

9、 Key operation error or failure ;

10、 Function not implemented ;

11、 Function error ;

12、 System refresh error ;

13、 Voice or data communication error ;

14、 Prompt information error, etc .

Interface optimization

As the name suggests, interface optimization is the optimization of operation interface .

Whether the layout of the functional modules of the user interface is reasonable 、 Is the overall style consistent 、 Whether the placement position of each control conforms to the customer's usage habits , Interface operation convenience 、 Whether the navigation is easy to understand ; Whether the style and presentation effect of the design conform to the design drawings, etc .

Common examples are ：

1、 The design style and presentation effect are inconsistent with the design drawings ;

2、 The string display is not uniform ;

3、 spell 、 Alignment class error 、UI Icon 、 Literal error ;

4、 The interface display is not beautiful ;

5、 Information is blocked , The position is wrong ;

6、 The picture is misplaced , Problems such as irregular text arrangement .

User experience

User experience is a purely subjective feeling established by users in the process of using products . But for a well-defined group of users , The commonness of its user experience can be recognized through well-designed experiments .

In a nutshell , It is the human-computer interaction between products and users , Is it friendly , Is it reasonable ;

Examples are ：

1、 The auxiliary description is not clear ;

2、 No prompt for operation ;

3、 There is no obvious distinction between the inputable area and the read-only area ;

4、 Some wrong words that do not affect the understanding of the product ;

5、 Some small problems such as irregular arrangement of words ;

6、 The user interface is not very friendly ;

7、 Not used to ;

8、 Adjust the size of the controllable area of the operation button ;

9、 Good operation suggestions, etc .
