The OP-Pohjola Group has a complex business management system that demands exhaustive testing in the event of any changes. During 2011, three full-time testers were employed to test the system. In their estimation, updates planned for the future would demand a considerable increase in investment in total hours of testing.
Due to the lack of a suitable method for storing old, reusable data, testers manually prepared all test data.prior to each test run, and for each individual test case. In their own estimation, 20% of their working hours went to updating test data.
