Improvement of software testing processes with test maturity model integration (TMMi)

In this study, maturity and level determination and evaluation methods which are developed in order to be able to perform TMMi 2nd and 3rd Level evaluations before the audit are given from the firms operating in the software insdustry with the understanding of improvement in test processes. With this method, it is aimed to help companies to make their own self-assessments before they participate in the evaluations that they will make by allocating high budget and to improve the test processes by increasing their maturity level. The validity of this method has been tested in the 2nd and 3rd level evaluations of TMMi. Companies operating in the software industry can prepare for an official TMMi audit if they wish, using the test maturity level determination method prepared within the scope of this thesis, to help them better understand and develop software testing processes. If they want to improve their processes, they can create better quality and valid products, or if they already have such a certificate, they can control themselves at any time to ensure its continuity.With this study, it will be a study that will be helpful to show the usage of TMMi model related to the software testing process, to make a suggestion that can be a guide in determining the test process maturity level, to make a contribution to the literature by taking a detailed study on TMMi subjects which have a small number of available resources in the literature and to include practical application.
