Abstract: A mechanism is provided for automatic testing a software product comprising a plurality of software packages that are to be installed or de-installed in defined order. Software package dependency and prerequisite information is analyzed for each software package and a dependency abstraction level matrix is created for the software packages. The dependency abstraction level matrix is reduced by searching for software packages assigned to more than one abstraction level, determining the highest abstraction level the software package is assigned to, and deleting the software package from lower abstraction levels that the software package is assigned to. Possible software package test combinations of the software product are determined based on the reduced dependency abstraction level matrix. An installation or de-installation procedure of software packages is performed based on the software package test combinations to test installation or de-installation order of the software packages.
