Equivalence class Partitioning Example 2

Title: instance of equivalence class is increased to three boxes, click OK button to determine the test case character in three boxes does not meet the requirements.

Understanding of the topic: The equivalence class used for this problem is similar to the equivalence class used in the last box, but I made some improvements, and then I designed the test cases separately in three edit boxes to achieve:

The equivalence classes for partitioning are:

by condition	Number	Valid equivalence classes	Number	Invalid equivalence class
Length	1	1~6	3	Length 0 or greater than or equal to 7
Character	2	Contains A~z,0~9,a~z	4	Contains control characters and punctuation marks

Test Case:

NO	Editbox1 input	Editbox2 input	Editbox3 input		Expected output
1	Axw2	ds0a	Dwdw		Editbox1 input legal Editbox2 input legal, EDITBOX3 input legal
2	2ew	0	Sdjdjsf		Editbox1 input Legal, editbox2 input length is not legal, editbox3 input length is not legal
3	2ew	' FD	0		Editbox1 input valid, Editbox2 input character is illegal, editbox3 input length is not legal
4	12dsdcxc	Ew3	&djsi		Editbox1 input character is illegal, editbox2 input is legal, editbox3 input character is illegal
5	0	Disdgjhj	2rfA		Editbox1 input length is not valid, Editbox2 input length is illegal, editbox3 input is legal
6	Asj1	AXs3	0		Editbox1 input Legal, editbox2 input legal, editbox3 input length is not legal
7	Aow	0	Sak		Editbox1 input Legal, editbox2 input length is not legal, editbox3 input legal
8	0	Dsd	Qd		Editbox1 input length is not valid, Editbox2 input is legal, editbox3 input is legal
9	, WR	Ds	Fd		Editbox1 input character is illegal, editbox2 input is legal, editbox3 input is legal
10	Dosd	;d C	Fs		Editbox1 input valid, Editbox2 input character is illegal, editbox3 input is legal
11	FFs	Fs	[VD		Editbox1 input Legal, editbox2 input legal, editbox3 input character is not legal
12	Dskddsd	Dw	Hs		Editbox1 input length is not valid, Editbox2 input is legal, editbox3 input is legal
13	Edjw	Fsfdfdffd	ew		Editbox1 input Legal, editbox2 input length is not legal, editbox3 input legal
14	Fe	Fdf	Rwewrrr		Editbox1 input Legal, editbox2 input legal, editbox3 input length is not legal
