• Equivalence Partitioning Method is also known as Equivalence class partitioning (ECP). It is a software testing technique or black-box testing that divides input domain into classes of data, and with the help of these classes of data, test cases can be derived. An ideal test case identifies class of error that might require many arbitrary test cases to be executed before general error is observed.

    • If the range condition is given as an input, then one valid and two invalid equivalence classes are defined. 
    • If a specific value is given as input, then one valid and two invalid equivalence classes are defined. 
    • If a member of set is given as an input, then one valid and one invalid equivalence class is defined. 
    • If Boolean no. is given as an input condition, then one valid and one invalid equivalence class is defined.
