Structural Testing or White-Box testing by definition is the testing of Software solution's internal structure, design and coding. The code is therefore visible to the tester, who can verify the internal flow of variables and outputs based on operations of those inputs. This allows the tester to identify areas of improvements. Black-Box testing on the other hand is where the software is tested for behaviour, therefore internals are not visible to the tester.
