Test cases of software testing

For software test cases, we have many methods, such as equivalence class partitioning method, boundary value analysis method and causality diagram method. There are different ways to think differently, so we have to learn to use test cases reasonably to achieve the results we expect.

Take a question as an example:

EditBox

Allow 1 to 6 characters or numbers, press OK to end.

Analyze its valid equivalence classes:

Length: 1 to 6

Character: a-z,a-z,0-9

Parse its invalid equivalence class:

Length: 0,7

Characters: Characters outside of English and numerals, control characters, and punctuation

Based on the above analysis, we can design its test cases:

Number	Test Cases	Results
1	1	True
2	123	True
3	123456	True
4	1234567	False
5	Null	False
6	A	True
7	Abc	True
8	ABCdef	True
9	Abcdefg	False
10	A	True
11	Abc	True
12	ABCDEF	True
13	ABCDEFG	False

The above use case not only takes into account the equivalence class partitioning method, in which the numbers 1, 3, 6, 8, 10 and 12 also take into account the boundary value analysis method, I think more reliable and effective test cases, I hope there is worth reference to the place.
