  29. TPRO-26 TEMA Conclusions for Testing Information Systems The development project should be accompanied by a separate test project. Both development and test should be based on the requirements specification. The budget for the test project should be equivalent to that for the development project. The test project should proceed methodologically from the test design to the test execution and evaluation. The test project results should be subject to a similar quality assurance as the development results. 1 2 3 4 5
