The concept and testing method of black box testing

Reader questions: What is black box testing and what are the testing methods?

Answer:

One, black box test

Black box testing does not care about the internal structure and implementation of the software.

We can treat the software as a black box. By entering data and related operations on the black box, we can observe the running results of the program and compare the actual results with the expected results.

Black box testing includes functional testing and non-functional testing.

Functional testing can be divided into different stages: unit testing, integration testing, system testing, acceptance testing, and regression testing.

Non-functional testing includes: performance testing, stress testing, load testing, security testing, compatibility testing, usability testing.

Second, test method

Black-box testing methods include: equivalence class division method, boundary value analysis method, wrong speculation method, cause and effect diagram method, decision table-driven method, orthogonal experimental design method, function diagram method, scenario method, etc.(The specific details are not expanded, and there is a lot of search on the Internet)

A Chang's thoughts:

The above is the basic theory of software testing, which is a bit general.

But when Ah Chang was actually on the job and came into contact with the real test project, the basic concept would be self-defeating.

Practice brings true knowledge, more hands to diligent brain.
