1. Software Defect attribute classification:

 

Attribute name	Description
Identifier)	A defect identifier is a group of symbols that mark a defect. Each defect must have a unique identifier
Defect type)	Defect types are the types of defects that are divided based on the natural attributes of defects.
Severity)	The severity of a defect refers to the extent to which the fault caused by the defect affects the software products.
Priority)	Priority of a defect refers to the degree of urgency to which the defect must be repaired.
Status)	Defect status indicates the progress of a defect by tracking the repair process.
Origin)	The source of a defect refers to the phase in which a fault or event is detected for the first time.
Source)	The source of the defect refers to the cause of the defect.
Root Cause)	The root cause of a defect is the root cause of an error.

2 categories of Common Software defects:

Defect type no.	Defect type	Description
10	F-Function	It affects important features, user interfaces, product interfaces, hardware structure interfaces, and global data structures. The design documents must be formally changed. Such as logic, pointer, loop, recursion, function, and other defects.
20	A-assignment	You need to modify a small amount of code, such as initialization or control blocks. Such as declaration, repeated naming, range, limitation, and other defects.
30	I-Interface	Defects that affect other components, modules, or device drivers, call parameters, control blocks, or parameter lists.
40	C-checking	Error messages, improper data verification, and other defects.
50	B build/package/merge	Errors Caused by configuration library, change management, or version control.
60	D-Documentation	Affects release and maintenance, including comments.
70	G-Algorithm	Algorithm error.
80	U-User Interface	Human-Computer Interaction Features: screen format, validation of user input, functional effectiveness, page layout and other defects.
90	P-Performance	Does not meet the property values that can be measured by the system, such as execution time and transaction processing rate.
100	N-norms	Does not meet the requirements of various standards, such as coding standards and design symbols.

 

3 software defect severity classification:

#	Severity Level	Description
0	Block	Very serious error, such as program cannot run blocking test
1	Critical	You cannot perform normal functions or important functions. For example, program crashes, crashes, and memory leaks.
2	Major	General critical errors, such as unreasonable program processing and unlimited boundaries
3	Minor	General problems mainly refer to non-standard interface, unclear display, unfriendly display, etc.
4	Trivial	Small errors usually refer to issues or suggestions related to user experience.

4Software Defect priority classification:

#	Priority Level of defects	Description
1	P1	The highest priority, for example, defects that cause major software functional errors or software crashes and data loss.
1	P2	High priority, such as general defects that affect software functions and performance;
2	P3	General priority. For example, some characters in the localization software have no translation or inaccurate translation defects;
3	P4	Low priority, for example, defects that have a slight impact on the quality of software or have a low probability;

 

5. The defect categories of CMM are as follows:

Defect type Defect type	Defect name Defect name	Description Description
10	Documentation Document	Comments, software unit description Annotation, software unit description
20	Build, package Version, package	Change management, library, Version Control Change management, database files, and Version Control
30	Assignment Assignment	Declaration, duplicate name, scope, limit Declaration, repeated name, range, and restriction
40	Design entities Interface Design entity Interface	Procedure CILS and reference, I/O, user formats   Process call and reference, I/O, user format
50	Checking Verify	Error message, inadequate checks Error message, improper verification
60	Data Data	Structure, content Structure, content
70	Function Function	Logic, pointer, loop, recursion, computation, Function Logic, pointer, loop, recursion, calculation, Function
80	System behavioral System behavior	Configuration, timing, memory Configuration, processing efficiency, memory
100	Performance Performance	Metric values for measurable attributes of the system, execution time, timing of event, etc, Metric values of measurable attributes, such as execution time and transaction processing efficiency
110	Quality Quality	Attributes of the system: usability, portability, reliability, maintainability System features: availability, portability, reliability, and maintainability
120	Constraints Restrictions	Constraints under which the system must operate usually affected by policies ies or regulations such as security, safety, or restriction hardware, etc... Restrictions that must be followed by a system, typically influenced by policies or decrees, such as security or hardware restrictions
130	Software Interface System Interface	Data management systems, operating system, other applications Data management system, operating system, and other applications
140	User Interface User Interface	Characteristics for the human/Computer Interaction: screen format, validation for user input, function availability, page layout, etc... Features of human-computer interaction: screen format, user input confirmation, function validity, page layout, etc.
150	Norms Standard	Notation for design entities Representation Design entity representation symbols
