Both white box and black box testing end up with a report on the vulnerabilities detected in the customer’s network. Black-box and white-box are test design methods. White box testing is the software testing method in which internal structure is being known to tester who is going to test the software. In the black box model, a report features so-called remediation – possible preventive measures, based on contractor’s experience. Independent Testing Team usually performs this type of testing during the software testing life cycle. A developer has to test if these programming constructs are placed correctly and carries out the required action or not.
