1. Use various testing techniques and methods to test and find software defects in software. Testing techniques are mainly divided into black box testing and white box testing.
Among them, black-box testing technology mainly includes equivalence class division method, boundary value method, causality chart method, state diagram method, test outline method and various typical software fault models. The main technologies of white-box testing include statement coverage, branch coverage, decision coverage, basic path coverage and so on.
2. Testing needs to run through the whole software development life cycle. Complete software testing includes unit testing, integration testing, verification testing and system testing.
Unit testing is mainly completed in the coding stage, which is jointly completed by developers and software testing engineers. The main basis is detailed testing. The main work of integration testing is to test whether the interfaces between software modules are realized correctly, and the basic basis is the software architecture design.
Confirmation test and system test are to verify the consistency between the functions and requirements of the software and whether the system functions of the software meet the requirements of users under the corresponding hardware conditions after the software development is completed. The main basis is the requirements of users.
3. Testers compile the found defects into formal defect reports and submit them to developers for defect confirmation and repair. The main requirement of defect report writing is to ensure the recurrence of defects. Testers are required to have good writing skills and language organization skills.
4. Testers need to analyze the software quality. After the test is completed, testers need to analyze the software quality according to the test results, including defect rate, defect distribution and defect repair trend.
Specific measures of various quality characteristics of software are given, including functionality, reliability, ease of use, security, time and resource characteristics. Finally, the conclusion whether the software can be released or submitted to users is given.
5. In the process of testing, in order to better organize and implement testing, the person in charge of testing needs to make a test plan, including testing resources, testing progress, testing strategies, testing methods, testing tools and testing risks.
6. In order to test better and more effectively and ensure the quality of testing work, testers need to design test cases and form test case reports before testing work.
Designing test cases is the core work to ensure test quality, and many test techniques can be used to guide the design of test cases. In order to improve the design efficiency of test cases, the BTEST training class has specially set up a course of efficient design of test cases, teaching various techniques and methods of design cases.
7. In order to improve work efficiency or test level, testing needs to introduce automated testing tools, and testers need to learn to use automated testing tools, write test scripts, and conduct performance tests.
8. During the test, the person in charge of the test needs to constantly improve the test process, improve the test level and build a test team according to the actual situation.
