There is provided a method of test plan generation for live testing and corresponding system and non-transitory computer readable media. The method comprises generating test configurations under which a plurality of test suite items (TSIs) are to be run, merging call paths, in a plurality of groups, according to intersections of call paths on which each of the plurality of TSIs are to be applied and environment coverage associated with the TSIs. The method comprises selecting a test method for each configured instance in each call path associated with one group of call paths. The method comprises creating an initial UML Testing Profile (UTP) model by mapping the TSIs to UTP test cases, thereby generating test runs, and deleting any duplicate test runs. The method comprises ordering test runs and selecting a test runtime framework for each TSI for which the test plan is generated.
