What is software testing? What should I learn from software testing?

Software testing is defined as the process of executing a program to discover errors in the program. It is the correctness of computer software that helps identify development (intermediate or final version) complete and quality software processes are important subdomains of SQA (Software Quality Assurance. What should I learn from software testing?

First, you need to learn more development, such as: Database (oracle \ sqlserver \ mysql programming), VB \ Vc, HTML \ ASP \ PHP, testing Theory (software engineering \ test process \ black/white box test method \ CMM), testing documents (test plan \ test cases \ test report-both Chinese and English ); the multi-Learning Test Tool (robot \ LR \ wr \ qtp \ some tools in Linux) and test the project management tool (TD \ VSS \ CVS \ Bugzilla \ Project ).

Also, learn more about the operating system (windows2000server \ Linux -- Common commands \ Services \ shell programming) and information security knowledge. There is also more projects, accumulated experience, and more time to communicate with people in the testing circle. In addition, the main work of software testing is verification and validation. The concepts are given below:

Verification is a series of activities that ensure that the software correctly implements some specific functions, that is, to ensure that the software does what you expect. (Do the right thing)

1. Determine whether the product in a given stage of the software life cycle meets the requirements established in the previous stage;

2. Formal proof of procedural correctness, that is, the process of using formal theory to prove the procedural symbols as defined in the Statute;

3. Evaluation of various activities, such as city, review, test, inspection, and audit, or judgment and report on whether certain items, services, or documents are consistent with the specified requirements.

To successfully develop high-quality software products, we must pay attention to and strengthen software testing. After several years of development, in order to win the competition, Chinese software enterprises pay more and more attention to the "economic value" of software testing (software testing can reduce the number of Software defects by more than 70%, with a return on investment of up to 350%), many companies have successively set up the software testing department. software outsourcing companies and third-party testing institutions that focus on testing have also emerged, leading to a dramatic increase in the demand for software testing talents.
