Testing strategies are not a new concept; they are used in development companies to present a strategy and an approach for how the testing of the software should be performed. However, test strategies are often specialised for individual companies or projects. Following an analysis of test strategies, the authors of the report have found a lack of test strategies that are generalised, that companies or projects can quickly start using to begin their software testing. This report will formulate and create a generalised test strategy that can be used by a number of small to medium-sized companies and projects. The method selection design science performs an iterative process where an artefact is created, the generalised test strategy. Developers from Greater Than AB participate in the design science process and test the generalised testing strategy. During each iteration, the generalised test strategy is evaluated through interviews with developers who participated in the testing of the generalised test strategy. With the interviews, each part of the generalised test strategy is examined and thus, the generalised test strategy is iteratively improved. The results of interviews conducted include what is added to the generalised test strategy and the artefact produced, the generalised test strategy, indicates a successful generalisation of a test strategy.
