QA is QualityAssurance, which focuses on quality measurement and inspection, and improves the quality of software through improvement process, thus guiding the release of software. The focus of QA is to manage the product life cycle and verify whether the software meets the defined quality standards and user agreements. QA is not to analyze the software to find out the problem, but to verify whether the software can work under a given set of conditions.

1. Safety test

Security testing before the application goes online is an essential link, and it is necessary to check the basic user name and password, as well as whether there are security loopholes. Especially if this application is highly confidential, we should cooperate with network experts and security experts to do as much security prevention and control as possible during the inspection.

2. Stress testing

An application must pass the maximum load stress test at any time to simulate what kind of support the application needs to provide during use, so as to verify that the application can cope with this load. If the application runs on the Internet, the boundary of stress testing should also be extended from the place where the transaction is executed to the global Internet nodes. Sometimes, Internet bandwidth or services are limited in different regions. When an application fails in the stress test, it may mean that more processing power or storage space must be allocated to the application, or an alternate Internet channel must be opened to reach the bandwidth and service level required to support a specific geographical area. By working with network experts and application developers in stress testing scenarios, these potential checkpoints can be identified so as to solve these problems before deploying applications. Maituo software adopts the latest technical architecture and innovative design of high concurrency big data examination engine, which has stable performance under high concurrency and reduces operation and maintenance costs for customers.

3. User testing

Even if an application can perform the designed function normally, if the user can't understand or use it, the application foundation

It is useless in this book. This means that we should cooperate with end users in application testing to ensure that users can use the application conveniently. If this is not done, the application will not be used.

4. Multi-interface deployment

If you want to deploy the application on multiple terminals, you should adjust the appearance and size of the application user interface for each terminal. Before going online, we should check the availability of these different interfaces on various devices, check the loading time and other factors.

5. User support

Before deploying the application, the technical support department should systematically train the users, guide them on how to install and use the application, and give technical support to the problems in the use process in time.
