Test Cases: Four-Step Test Design Approach

Reader Questions:

阿常，上节我们讲到Test points are not equivalent to test cases, I would like to ask you how to process test points into test cases?

At present, testers in the team write different test cases for the same test point. One thousand people have one thousand Hamlets, and 108 testers will have 108 test ideas. How to ensure the output in the team?What about the quality of the use cases? Is there a better test design method?

A Chang replied:

Four-step test design method.

First, modeling.

Select a suitable model for the test point, and divide different test points into four types of models: process type, parameter type, data type, and combination type.

1. Process class, build a test model by drawing "Flowchart".

2. Parameter class, establish a test model through "input and output table".

3. For data class, establish a test model through "equivalence class analysis table".

4. Combination class, establish test model through "factor table".

2. Design basic test cases

Then we design some basic test cases for the established test model to cover this test model.

III. Supplementary test data

Determine test inputs for base test cases and supplement test data.

Four. Extension

According to the actual test experience, in addition to the test model, based on the understanding of where defects are likely to occur in the system, add some test cases to increase the integrity and effectiveness of the test cases.

A Chang's thoughts:

How to process test points into test cases, we will continue to discuss in the next question.
