Computer implemented methods and systems are provided for computing code coverage in a system that includes a user system and a cloud-based computing platform. The user system includes a processing system, memory and an input system that receives input parameters specified by a user of the user system. The memory can store a source class filter module executable by the processing system. Upon being executed by the processing system, the source class filter module can, based on one or more of the input parameters, group and filter source class identifiers to generate a unique source class identifier array of filtered source class identifiers that correspond to a particular subset of source classes that targeted code coverage metrics are to be computed for during code coverage computations when testing an application. A code coverage computation unit can then compute the targeted code coverage metrics for the particular subset of source classes corresponding to the filtered source class identifiers of the unique source class identifier array.
