How to understand traditional software testing

What does software testing need to do? I believe you can understand through the following answers.

1, demand analysis stage: as long as it is learning business, analyze demand points.

2. Test planning stage: The test team leader will start to write a test plan according to SOW, including personnel, software and hardware resources, test points, integration sequence, progress and risk identification.

3. Test design stage: Generally, senior test engineers who are familiar with the requirements design the test scheme. According to each demand point in SRS, the test scheme requires to design a scheme including demand introduction, test idea and detailed test method. After the test plan is written, it also needs to be reviewed.

4. Test scheme stage: mainly the design of test cases and programs. Test cases are written according to the test plan. Through the test planning stage, testers have a detailed understanding of the requirements of the whole system. At this time, writing use cases can ensure the implementation of use cases and the coverage of requirements. Test cases need to include test items, use case levels, preset conditions, operation steps and expected results. Among them, the operation steps and expected results need to be written in detail. Test cases should cover test plans, and test plans should cover test requirements, so as to ensure that customer requirements are not missed. Similarly, test cases need to be reviewed.

5. Test execution stage: execute test cases and submit quality bugs, test daily reports, test reports and other related documents in time.
