Traceability Matrix is a document used for tracking the requirement, Test cases and the defect. This document is prepared to make the clients satisfy that the coverage done is complete as end to end, This document consists of Requirement/Base line doc Ref No., Test case/Condition, Defects/Bug id. Using this document the person can track the Requirement based on the Defect id.
Boundary value testing is a technique to find whether the application is accepting the expected range of values and rejecting the values which falls out of range. Ex. A user ID text box has to accept alphabet characters ( a-z ) with length of 4 to 10 characters. BVA is done like this, max value:10 pass; max-1: 9 pass; max+1=11 fail ;min=4 pass;min+1=5 pass;min-1=3 fail; Like wise we check the corner values and come out with a conclusion whether the application is accepting correct range of values. Equivalence testing is normally used to check the type of the object. Ex. A user ID text box has to accept alphabet characters ( a - z ) with length of 4 to 10 characters. In +ve condition we have test the object by giving alphabets. i.e a-z char only, after that we need to check whether the object accepts the value, it will pass. In -ve condition we have to test by giving other than alphabets (a-z) i.e A-Z,0-9,blank etc, it will fail.
