What is the main purpose of having Equivalence Class
Particition & Boundary value analysis in Testing?

Answer Posted / gupta

EP-this technique is used to test when we got to test different combinations of inputs or when testing different permutations and combinations of data. we divide data into 3 equal partitions and test those partitions. for example consider a text box which can only accepts numbers from 1-100. in this case we can't write test cases for 100 input values. so we divide the data in to 3 equal partitions i) 1-100 ii)data value below 1 iii)data value above 100.
BVA- testing data at boundaries. for the same above example we test with the input boundary values 0,1,100,101

Correct me if i'm wrong.

Corrections are always welcome to enrich my knowledge.
Thanks
