I haven't had much contact with the cs test all the time, but I recently had the opportunity to learn about it and summarize my study notes.

1. From a testing point of view, cs can be divided into three parts, as follows:

A, a separate client

Integrated testing of b, client and server

Integrated testing of C, client, network and server

2. Comparison of structural characteristics between cs and bs.

A, most of the pressure of bs is on the server side; in the case of cs, the client side can share the write pressure

B, cs programs need to consider different versions of os

C. The cost of maintenance and upgrade of cs is high.

3. Advantages and disadvantages of cs:

Advantages of ★ Cpact S model

Because of the direct connection between the client and the server, ● has no intermediate link, so the response speed is fast.

● has a beautiful interface and various forms, which can fully meet the individual requirements of customers.

The management information system based on ● Cpact S structure has strong transaction processing ability and can realize complex business processes.

The disadvantages of ★ Cpact S mode

● needs a special client installation program, the distribution function is weak, for a wide range of points and do not have network conditions of the user group, can not achieve rapid deployment, installation and configuration.

● has poor compatibility and has great limitations for different development tools. If you use different tools, you need to rewrite the program.

The cost of ● development is high, and it can only be completed by technicians with a certain professional level.

4. The advantages and disadvantages of BBGUA S mode.

The advantages of the ★ BBBUBERS model

● has the characteristics of distribution, and can query, browse and other business processing anytime and anywhere.

The expansion of ● service is simple and convenient, and the server function can be increased by adding web pages.

● maintenance is simple and convenient, only need to change the web page, you can achieve synchronous updates for all users.

● is easy to develop and has strong sharing.

The disadvantages of ★ BBBUBERS mode

The personalization characteristics of ● are obviously reduced, and it is unable to achieve the functional requirements of personalization.

● operation takes the mouse as the most basic operation mode, which can not meet the requirements of fast operation.

The ● page is dynamically refreshed, and the response speed is obviously reduced.

● can not realize paging display, which puts great pressure on database access.

The function of ● is weakened, so it is difficult to realize the special functional requirements under the traditional mode.

5 、 css

That is, client-middle-server adds middleware to handle business logic.

6. Factors affecting the performance of CS/CSS system architecture.

It is very difficult for test engineers to test the performance of a CS/CSS system because of the following characteristics:

All parts of the system use a variety of operating systems, and the performance is different.

L multiple databases are used in all aspects of the system architecture, and there are also differences in performance.

L applications are multiple, belong to multiple categories, and are distributed on different devices, including self-developed applications and third-party applications

The devices and components in the system are connected and communicated through different protocols.

L the system has many internal interfaces and performance bottlenecks, while the overall performance of the system often depends on the worst part; it needs to be tested separately and jointly.

The performance index of the system is not only related to the application system architecture, but also related to the business model of industry-specific applications.

The industry application using this architecture is often a 7 × 24-hour system.

Industry applications that adopt this architecture may have more high-end business, which will affect the selection and conversion of performance metrics.

Each link basically communicates in the way of exchanging data messages, and its format is often complicated.
