can any one explain with example the diff between boundary
value analysis testcasees and equivalence class testcases
pls urgent

Answer Posted / kishore

Keep it simple
BVA: test cases on boundaries.
how? min--max is the range

min,min+1,min-1 and max,max+1,max-1

apply above rule for the min max boundary

Now ECP: divide the input range in the class
one valid and two invalid (for any type of range)
true and false ( for boolean)
so, when u divide ur input into valid and invalid class
there also falls boundaries. Now, apply ur BVA techniques to
minimise the test cases.

suppose input domain is 1-20
valid class=1-20
invalid class less than 1
invalid class more than 20

Hope the answer is clear to you
