Abstract: According to some embodiments, systems and methods are provided, comprising an Application Programming Interface (API) source; a cluster including a master node and at least one worker node; a memory storing processor-executable program code; and a processing unit to execute the processor-executable program code to cause the system to: receive, at the cluster, an API from the API source; receive, at the cluster, a customer usage value for the received API; determine a load test injection pattern for the received API based on the customer usage value; schedule execution of a load test for the received API based on the determined load test injection pattern; and execute the load test on the at least one worker node. Numerous other aspects are provided.
