This article mainly introduces "what is the meaning of black box testing". In daily operation, I believe that many people have doubts about the meaning of black box testing. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the question of "what does black box testing mean?" Next, please follow the editor to study!

What is a black box test?

Black box testing means that testers regard software products or phased products as a black box. In the process of testing, testers only need to care about the results of operating on this software black box. There is no need to go deep into the internal implementation of the software.

That is to say, black box testing only considers the input and output of the system, regardless of the internal structure and processing of the program)

Second, why do you want to do black box testing?

1. Verification

Verify that the software product conforms to the design of the requirements document

two。 Confirm

Confirm that the software product meets the needs of the end user

Third, which testing phases in the software life cycle will use black box testing?

1. The life cycle of software

(1) Unit test

(2) Integration testing

(3) system testing

(4) user acceptance test

two。 Generally speaking, black box testing is suitable for all testing phases of the software life cycle, but black box testing is usually used in the system testing and acceptance testing phases of software products.

Ps: black box testing is also used for performance testing and functional testing of software products

Fourth, the advantages of black box testing

1. From the point of view of product function, it can meet the needs of users to the maximum extent.

two。 The same actions can be performed repeatedly, and the most boring parts can be done by machines.

3. Find the problem according to the test case, the location is more accurate, and it is easy to generate test data.

4. Tests can be directly associated with what the program / system is going to do

Fifth, the shortcomings of black box testing

1. The code cannot be tested.

Because the black box test will not look at the internal implementation of the system.

two。 If the specification is wrong, it is difficult to find it.

3. The test cannot be carried out fully

4. The accuracy of test results depends on the design of test cases.

5. The reusability of automated testing is low.

6. What are the test methods of black box testing?

1. Boundary value analysis

two。 Equivalent class division method

3. State transition test method

4. Causality diagram method

5. Grammar testing

At this point, the study of "what is the meaning of black box testing" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
