Equivalence class partitioning in software testing

Equivalence class partitioning:


It is a black box testing technique with the help of this technique we can divide the data into valid parts and invalid parts

For example take this requirement: Username should take alphanumerics only

For this requirement we can write ECP like this

Valid: all alphabets a to z, all numbers 0 to 9 

Invalid: special characters

After that we can write testcases like this

Positive test cases:

1) Verify the functionality of the username field by entering alphabets
2) Verify the functionality of the username field by entering numbers

Negative test case

1)Verify the functionality of the username field by entering specials characters
