True question 60: in the following statement about the boundary value test, what is incorrect is ()

a. Boundary value analysis not only pays attention to the boundary of input domain, but also must consider the boundary of output domain.

b. Boundary value analysis is a supplement to the equivalent class division method.

c. Fewer errors occur on the input-output boundary than internal errors occur in the input-output range

d. The test data should select the value on the boundary as much as possible, rather than the typical or arbitrary value in the equivalence class.

Analysis and answer: this question examines the boundary value test method in the black box test, there are more errors on the input and output boundary than internal errors in the input and output range, so the correct answer to this question is C.

True question 61: the white box test cannot be found ()

a. Errors in the code path

b. Endless cycle

c. Logic test

d. Functional error

Analysis answer: White-box testing does not care about functional requirements, so it is impossible to determine whether the function is correct or not. So the answer to this question is D.

True question 62: how many test cases are required to complete the conditional combination coverage for logical expressions ((axifolb) | | c).

A.2

B.4

C.8

D.16

Analysis and answer: this question examines the conditional combination coverage of the logical coverage method in the white box test.

The meaning of conditional combination coverage: select enough test cases, as if all possible combinations of conditions in each decision appear at least once. There are three conditions in this question, and the test case required after the combination is 8. So the answer to this question is C.

Question 63: in order to detect whether there is a performance bottleneck in the system running for a long time, () should be carried out.

a. Load testing

b. Pressure testing

c. Fatigue strength test

d. Large data volume test

Analysis and answer: the goal of this question is to test the performance of the system under long-term operation, and fatigue strength test should be carried out. So the answer to this question is C.

Question 64: in the following description of load stress test, what is incorrect is ()

a. Load stress tests are used to confirm that performance requirements are supported

b. The load stress test can get the increase of the business volume that the system can bear.

c. Load pressure test is the maximum load pressure that the test system can bear under certain constraints.

d. Load stress testing is not used to find problems such as slower speed and memory leaks under different load scenarios.

Analysis and answer: load stress tests can find that the speed becomes slower and memory leaks under different load scenarios, so the correct answer to this question is D.
