Testing of a resource manager of an application management system

A testing system for testing a resource manager of an application management system, the testing system comprising:

• a processor;
• and
• a memory device that store program code to be executed by the processor, the program code comprising:
• a load orchestrator communicatively coupled to a first application instantiated in a computing node of a cluster of computing nodes, the load orchestrator configured to:
• receives the utilization model via an application programming interface;
• generates an artificial metric value based on the received utilization model, the artificial metric value representative of a value of a metric reportable to the resource manager by the first application;
• and
• transmits the artificial metric value to the first application, the first application configured to transmit the artificial metric value to the resource manager and the resource manager configured to generate control output for managing the first application in the cluster of computing nodes based on the artificial metric value after receiving the artificial metric value from the first application.

A testing method for testing a resource manager of an application management system, the testing method comprising:

• obtaining, by a load orchestrator, an artificial metric value generated based on a utilization model, the artificial metric value representative of a value of a metric reportable to the resource manager by a first application instantiated in a cluster of computing nodes;
• and
• transmitting, by the load orchestrator, the artificial metric value to the first application;
• receiving, by the resource manager, the artificial metric value from the first application;
• and
• generating, by the resource manager, control output for managing the first application in the cluster of computing nodes based on the received artificial metric value.
