Bugs are commonplace for testers, after all, finding software bugs is part of the work of testers. However, it is not enough to find bugs. At the same time, it is necessary to avoid the reappearance of bugs and do a good job in software quality assurance. Therefore, a good bug analysis is a very important thing. Next, the editor will share with you the correct way to open the bug analysis.
1. The first is to know the bug
What is a bug? The original meaning of bugs is bugs, defects, damages, poverty, bugs, bugs, etc. Now people will collectively call some undiscovered defects or problems hidden in computer systems or programs as bugs (vulnerabilities).
Due to the development of modern society, bugs have another extended meaning. They are used to describe something that is beyond imagination. Bugs can crash computer systems and are easily attacked by fraudsters. There are tools to fix vulnerabilities.
And software bugs are caused by the negligence and mistakes of software developers.
Moreover, software bugs are the sum of all problems found and undiscovered during the software life cycle.
Software bugs do not only refer to the functional errors of the software system found in the software testing phase, but also include the problems found in the review process of requirements, design, and development during the software development process, as well as the problems found and feedback by customers after the software is released. Including those hidden in the software that have not been discovered for the time being.
2. Obtain specific bug data
Obtaining bug data is the first step in bug analysis. A complete and clear bug data record is the key to bug management and analysis.
Record bugs according to attributes to meet the analysis needs of different dimensions and different indicators.
The living environment and life cycle of software bugs determine the person, process, organization and other links, various methods and measures in the software development process, which will cause bugs. Through bug analysis, you can find the deficiencies of software development links, methods and measures. Through multi-dimensional, multi-level analysis to discover the root causes of bugs and improvement methods, improve the quality of software products through improvements, and enhance the capabilities and adaptability of people, processes, and organizations.
3. Effectively manage bugs
The purpose of management is to allow management objects to work in a standardized and efficient manner, and to obtain higher benefits from management.
The purpose of software bug management is to achieve standardization, process, and standardization of bug management, so that all bugs found in the software development process can be fully recorded and effectively tracked. At the same time, use statistical analysis methods to discover the causes of bugs, study prevention and solutions, and implement them effectively to achieve continuous improvement of software, processes, people and organizations.
The software bug management process and tools should meet the three main functions of information entry, tracking and query, and statistical analysis.
Fourth, do a good job of bug analysis
Analysis is to divide the whole of the research object into various parts, aspects, factors and levels, and to investigate and understand them separately.
Software bug analysis is to take all the bugs that appear in the software life cycle as the research object. From the analysis of the stages of bug generation, the modules generated, and the causes, to discover the problems in the process, stage, technology, people and organization of the software life cycle. . As well as the collaboration between key links and elements in the software development process, through adjustment, improvement and control, software quality can be improved, software costs can be saved, organizational productivity, and high-quality software results can be delivered.
1. The purpose of bug analysis
The basic ug analysis is based on the bugs found in the testing phase. Through the distribution and trend research of the bugs, the root causes of the bugs are found, and adjustment and control measures are taken as early as possible to prevent and control the spread of problems and the generation of new problems, and to improve software quality.
In-depth bug analysis is based on all the bugs that appear in the software life cycle, using statistical analysis methods to discover technical, human, process, project and organizational problems in the software life cycle through the commonality of bugs, revealing software quality, process quality, and personnel capabilities , The relationship between organizational capabilities, strengthen software refined management, and promote continuous improvement of people, processes, and organizations.
2. The basis of bug analysis
Software quality is not checked out, but produced.
People create software, build software quality, and also produce a lot of bugs. It should be noted that talents are the main body of software production. Many people with different personalities and technical abilities form the software organization, and human software activities constitute the software production process.
Therefore, the final decision on software quality is people, and the ultimate goal of software bug analysis lies in the analysis of people. Through bug analysis, discover human defects and deficiencies (technology, communication, standardization, etc.) in the software life cycle, formulate targeted methods and training to improve personnel technical and communication skills, enhance the standardization of human activities in the software process, and reduce human intervention The negligence and mistakes, and finally build an effective software process, improve the overall productivity of the organization, and improve the quality of software delivery.
Five, in-depth bug analysis
1. Bug is a very important data in the software life cycle and should be paid enough attention and fully utilized.
2. Pay attention to the accumulation of bug data in the organization, use standard processes and mature defect management tools to manage Bbugs, and perform basic analysis on bugs through the analysis methods provided by the defect tools.
3. In-depth bug analysis, improve the quality of bug use, and explore the value of bug use.
4. Strengthen hierarchical analysis based on bug data statistics. According to different dimensions and levels of project, process, stage, module, technology, people, etc., conduct vertical correlation analysis within the life cycle of the same software, and conduct horizontal comparative analysis between different software to obtain multi-dimensional and multi-level analysis data to achieve lean Software development, measurement and management.
5. Using data mining methods, analyze the relationship between the occurrence of bugs and the people, processes, and organizations in the software development process, discover the deep-seated causes of bugs, study solutions, and prevent and reduce the occurrence of bugs. Form the data support from bug analysis to the improvement of organizational production capacity, and complete the positive drive from the improvement of organizational production capacity to the growth of personal quality.
6. Use third-party data analysis tools to efficiently perform statistical analysis on bug data, realize multi-dimensional and multi-level dynamic analysis and display of bug analysis based on powerful analysis functions, improve the effect of bug analysis, and realize bug visualization and refined management. Provide multi-faceted data support for the lean management of software organizations.
