The editbox of application of equivalence class partitioning method

In this week's software testing lesson we learned the equivalence class partitioning method, and in this work further familiar with the application of this method, using this method to study the editbox use case.

Functional Requirements:

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

Valid equivalence classes:

Length: 1 to 6

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

invalid equivalence class:   Length: 0,7

Characters: English/numeric characters, control characters, punctuation

equivalence class partitioning:

	Valid classes	Invalid class
Length	1 to 6	0,7
Character	A-z,a-z,0-9	English/numeric characters, control characters, punctuation

test Case:

Number	Input	overriding equivalence classes	Output
Test1	123456	Length 1 to 6, character 0-9	Enter the correct
Test2	123abc	Length 1 to 6, character 0-9, A-Z	Enter the correct
Test3		Length of 0	Please enter a character with a length of 1-6
Test4	1234567	Length 7, character 0-9	Please enter a character with a length of 1-6
Test5	Abcdefg	Length is 7. Character A-Z	Please enter a character with a length of 1-6
Test6	123!	Length 1 to 6, English/numeric characters, control characters, punctuation	Only English characters and numbers are allowed

Code and results:

This experiment would like to use the Java language to achieve, but there is a period of time useless some unfamiliar, instead of using JSP language to achieve.

Here is the code:

The results are as follows:
