How do testers ensure software quality?

2. Risk assessment: This ability is very important, and there may be risks in each stage of the project: unclear requirements, imperfect system design or test design, unsafe code writing, insufficient test cases, incomplete testing by testers, insufficient test resources, improper estimation of regression workload, improper project progress, and the impact of other projects on this project. Therefore, we should keep a high degree of vigilance during the project, especially in the development and testing stages. 3. Defect prevention: I personally think that good defect prevention needs comprehensive quality, such as skilled business ability. It is best to be familiar with the relationship between products, and it is best to understand the implementation methods and processes of products. Be able to predict the impact on this project in time according to the problems arising from the release of other products at present, and do a good job in analyzing related defects. 4. Communication ability: Testing and development are often antagonistic, and a discordant team will inevitably have a negative impact on the quality of the project. After all, people's emotions at work have a great influence on work efficiency, and software quality is guaranteed by development and testing. I remember that at the test technology exchange meeting, the boss Guo Fu said that developers' test awareness is not innate, and testers need to guide developers and improve their test awareness when they encounter insufficient test concepts. The developer's lack of testing consciousness can't be regarded as the reason of poor product quality, so communication ability is a good embodiment in this process. 5. Time management: People who can manage time are often one step closer to success. How to use time to solve urgent project problems, conflict problems, resource arrangement problems, and the execution order of test cases is one of the factors to ensure quality.
