Equivalence class partitioning method for black-box testing Software testing (2)

We often need to enter multiple information at the same time when filling in the information, and must meet the input requirement.

In the original input box to increase the input requirements, the input is increased to three, there is more than one illegal input is not the result of judgment, only three inputs are correct when the input is determined to be successful.

Equivalence class Partitioning

Number	Valid equivalence classes	Number	Invalid equivalence class
1	Length <6	5	Length = 0 or >7
2	Digital	6	control characters, punctuation
3	lowercase English letters
4	Uppercase English letters

Use Case number	Line	Two lines	Propelled	Results
(1)		Asd	Wer3	Illegal
(2)	Tcy2	Flower	Lion20	Pass
(3)	answ!	21345	3.1415	Illegal
(4)	112233	44556	7895999	Illegal
(5)	Apple	Banana	Peach	Pass
(6)				Illegal
(7)	[Email protected]	Br_er	Wer_12	Illegal
(8)	Asdfghjk	123	Asnf	Illegal
(9)	12345678	Fly	Carer	Illegal
(10)	Emanon	Neo	Jhon	Pass
