  • Today we will talk about the reconciliation testing approach. We think that it can be extremely useful in testing complex integrated trading systems. This approach can be applied at different test levels, and what is also important, the reconciliation tool can afterwards be re-used for carrying out the other activities, such as conformance testing. Reconciliation is a process to determine the differences in data obtained from the different sources. So the Reconciliation testing is the test approach applied when it is necessary to compare the output of different systems or system components. The level of required reconciliation may be different, from simple, which can be done using simple sql scripts, to quite complex, that requires the tool with built-in business rules. Therefore, we have decided to formalize this activity and now we include the reconciliation test approach to our test plans. We are also actively working on the development of appropriate test tools.
