The main objective of this thesis was to study how regression testing could be improved before maintenance phase during Seafarer's Pension Fund system renewal project by identifying and planning possible process improvements and tools that make testing more efficient. The renewed systems are heavily dependent on both external and internal interfaces based on web services. More efficient regression testing before maintenance phase is vital because the size of the test team will be significantly lower than during the ongoing implementation phase. This thesis starts with a relatively wide literature study on testing and test automation. In the final part this theory has been applied for the chosen project environment by forming a plan on required changes to development and testing process and required tools. A general tool for testing both external and internal web service and WCF interfaces with XML-based messages was identified as a required improvement as these kinds of interfaces are very common both externally and internally. The solution was planned on top of open source tool BizUnit, which enabies also test automation and chaining of the service calls to create a multi-phased process. During the work required extensions were also identified and planned. Another planned tool will help to efficiently analyze the impact of changes in the service schemas for internal applications. Evaluation of the planned changes takes place in the future after the implementation project during 2011. Before that planned changes are implemented as small pilot projects for systems that have already been deployed to production environment.
