1. There are many ways to design test cases, and each method has different applicable conditions. The following are descriptions of several methods:

For systems with clear business flow, you can use _ throughout the whole test case design process; comprehensively use various test methods in the use case, and use the combination of less selection for the software of the parameter configuration class to achieve the best results; if the functional description of the program contains a combination of input conditions, you can choose _ from the beginning.

For the above description, the option to fill in the blanks above in the correct order is (). (select one)

a. Equivalent class division method, causality diagram method, state diagram method

b. Scene method, orthogonal arrangement method, causality diagram method

c. State diagram method, equivalent class division method, causality diagram method

d. Causality diagram method, orthogonal arrangement method, equivalent class division method

Explanation and analysis: based on the system with clear business flow, the scenario method can be used throughout the test case process, and various test methods can be comprehensively applied on this basis; the orthogonal test method is simple and has significant advantages in the test case design of parameter configuration and compatibility; the causality diagram method is more suitable for the situation where there is a relationship between the input conditions and output results in the system, so the correct answer to this question is B.

two。 When using LoadRunner's results chart analysis function, you can break down the following () as a condition to determine whether there are network bottlenecks and server bottlenecks in the Web system. (select one)

A.Connection time

B.Receive time

C.Client time

D.First Buffer time

Explain the analysis:

Connection time: the time it takes to establish an initial connection, which reflects network problems. The smaller the value, the better.

Receive time: the time it takes to receive data, which reflects the size of the bandwidth. The greater the bandwidth, the shorter the download time.

Client time: think time or client request delay time

First Buffer time: after establishing a connection with the server, the time required to successfully receive the first buffer of the server after the first packet is sent by the server and transmitted over the network. Can reflect whether it is a network problem or a service problem. So the answer to this question is D.

3. There are the following C language program segments:

If (xylene 30 minutes >-10)

Zhen0

For the value of the variable XBI y, the combination of the following test cases () can meet the requirements of conditional combination testing.

① Xuan 50 Yoyo 10 ② Xuan 40 Ying 40 ③ Xuan 30 Yong Mui 10

④ xx 20 ⑤ x 30 y 30 ⑥ x 30 y 10

A. ①②⑤⑥ B. ③④⑤⑥ C. ①②③④ D. ①②③⑥

Explanation and analysis: conditional combination coverage is a strong way of coverage, and various combinations of conditions appear at least once, so the answer to this question is D.
