TEST DESIGN TECHNIQUES:
While developing the test cases if at all the test engineer
feels complex in some areas to over come that complexity
usually the test engineer will use test design techniques.
Generally two types of techniques are used in most of the
companies.
1. Boundary Value Analysis (BVA).
2. Equivalence Class Partition (ECP).
1). Boundary Value Analysis (BVA).
When ever the engineers need to develop test cases for a
range kind of input then they will go for boundary value
analysis. Which describes to concentrate on the boundary of
the rang.
Usually they test with the following values.
LB-1 LB LB+1 MV UB-1 UB UB+1
2). Equivalence Class Partition (ECP).
When ever the test engineer need to develop test cases for a
feature which has more number of validation then one will go
for equableness class partition. Which describe first divide
the class of inputs and then prepare the test cases.
