Software Testing--application of equivalence class partitioning method for multiple inputs

Examples of multiple input equivalence class partitioning test cases:

1. Question: Enter 1 to 6 English characters or numbers in three text boxes, and press OK to finish.

2. Equivalence class Partitioning:

Number	Valid equivalence classes	Number	Invalid equivalence class
1	Text Box 1 Length: 1-6	8	text box 1 length <1 or length >6
2	Text Box 2 Length: 1-6	9	Text box 2 length <1 or length >6
3	Text Box 3 Length: 1-6	10	Text Box 3 length <1 or length >6
4	Text Box 1 is a character: A-Z-A-0-9	11	Text 1 Enter characters other than alphanumeric, control characters, punctuation
5	Text Box 2 is a character: A-Z-A-0-9	12	Text 2 Enter characters other than alphanumeric, control characters, punctuation
6	Text Box 3 is a character: A-Z-A-0-9	13	Text 3 Enter characters other than alphanumeric, control characters, punctuation
7	Enter 3 sets of strings	14	Input 2 groups, 1 groups or no input

3. Test Cases:

Number	Text Box 1	Text Box 2	Text Box 3	overriding equivalence classes	Expected output
1	1as	2bf	3cade	1,2,3,4,5,6,7	Enter the correct
2	12345	Abcde	123ads	1,2,3,4,5,6,7	Enter the correct
3	1#3c	Asd34	Adaf4	1,2,3,5,6,7,11	Text Box 1 input error
4	1231244ad	Qwrj45	23ks	2,3,4,5,6,7,8	Text Box 1 input error
5	Asd	1b%sd	Sdada	1,2,3,4,6,7,12	Text Box 2 input error
6	@ #ada	12	sd3rrrr555	1,2,5,6,7,8,9,10,11	Text Box 1 input error Text Box 2 input error
7	[Email protected]$	1bdssdssd	%s	1,3,5,7,8,9.11,13	Text Box 1 input error Text Box 2 input error Text Box 3 input error
8	As		1sd	1,3,4,6,7	Text Box 2 input error

4. Summary:

In comparison, increasing the input to the Equivalence class division requirements more complex, strict, of course, test cases are also more complex, so we need to be cautious.
