Computer implemented methods and systems are provided for executing tests 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 test class filter module executable by the processing system. Upon being executed by the processing system, the test class filter module can, based on one or more of the input parameters, group and filter test class identifiers to generate a unique test class identifier array of filtered test class identifiers that correspond to a particular subset of tests that are to be executed during testing of an application. A test execution engine can then execute the particular subset of tests corresponding to the filtered test class identifiers specified in the unique test class identifier array.
