1. Overview of software testing defect:
Software defect management software is an important part of software testing, testers ensure that all defects discovered can be properly processed, and to avoid processing defects for effective management, in order to facilitate the management of defects, defect classification needs from different angles, such as the origin of defects, defect severity, defect priority, defect status.
2. defect severity
Defect severity can be judged from the software end-user perspective, consider the impact on the users of software defects caused by defects in the end the severity level can be divided into five levels from High:
- Serious flaws (Critical): can not perform work functions or important functions or endanger personal safety, severe grade defects can be classified according to the actual situation of the project.
Operation or use a feature, causing the program to quit unexpectedly, or the rest of the functions are not available, or cause frequent crashes and restart
serious Huaping
memory leak
user data is lost or corrupted
system Ben collapse / crash / freeze
program or module can not start normal or abnormal exit
serious numerical error
functional design and demand serious discrepancies
lead to errors other functions can not be tested
- More serious defects (Major): a serious impact on the basic functions of the system requirements, and there is no alternative, such as
Key operation error or malfunction
in the customer environment itself, there is no problem, network instability, frequent disconnection, dropped to realize functions and related needs serious discrepancies Function not implemented Function error
system error refreshing
voice or data communication error
slight numerical calculation error
functions or services provided by the system significantly affected
- Usually defect (Average Serverity): the minor loss of function, less serious, can be resolved through alternative means, for example:
Key operating occasional failures
word error handling invalid boundary value problem displaying important interface, users will have a certain impact on the
user interface errors (including the column names in the data window definitions, meanings are the same)
boundary condition error
message Error (including no information is given, an error message, etc.)
for a long time without the operation progress indication
system is not optimized (performance issues)
cursor jumps not set, the mouse cursor positioning error
- Minor defects (Minor): the operator is inconvenient or trouble, but it does not affect the function or the implementation of important features such as:
String display is not uniform
spelling, aligned such mistakes, UI icon, the text of the error
screen displays unsightly, but the problem does not affect the user
does not often and not a serious problem users recoverable
assistance in explaining description is not clear
when the operation is not users are prompted to
enter the area of the read-only area and there is no obvious distinguishing mark
of individual products do not affect the understanding of the error word
text irregular arrangement and some other minor problems
- Improved defect (Enhancement): individual functions is not convenient enough to use, but the problem does not affect users, such as:
User interface is not very friendly
to use are not used
If you need video software resources, you can leave a message, Lok personally distributed software test video, documentation resources.
