TMC Level Integration Testing

The TMC level integration testing is aimed to confirm the integration of all the TMC Mid components and verify that the TMC complies with the requirements. The default approach for testing is automation testing. The deployment setup for this testing involves deployment the TMC and simulate all dependent subsystems using simulators. The simulators for this purpose are developed by TMC teams. BDD test scenarios are implemented to test the TMC level functionality. The entry point of the scenarios are the TMC devices that provide public API interface and results are asserted based on the output expected from TMC.

Commands Implemented

To execute the tests, run the command:

make k8s-test MARK=SKA_mid

  • TelescopeOn - Test the On command on TMC with multiple subsystems.

  • TelescopeOff - Test the Off command on TMC with multiple subsystems.

  • AssignResources - Test the AssignResources command on TMC with multiple subsystems.

  • ReleaseResources - Test the ReleaseResources command on TMC with multiple subsystems.

  • Standby - Test the Standby command on TMC with multiple subsystems.

  • Configure - Test the Configure command on TMC with multiple subsystems.

  • End - Test the End command on TMC with multiple subsystems.

  • Scan - Test the Scan command on TMC with multiple subsystems.

  • EndScan - Test the EndScan command on TMC with multiple subsystems.

  • Abort - Test the Abort command on TMC with multiple subsystems.

  • Restart - Test the Restart command on TMC with multiple subsystems.

Negative test cases Implemented

Timeout

The following tests verify the timeout behavior of the Configure command on various leaf nodes:

  • Test Configure Timeout on CSP, SDP and Dish Leaf Nodes

    • Induces a fault in the CSP, SDP, and Dish Leaf Nodes to simulate a timeout scenario.

    • Verifies that the subarray transitions to the CONFIGURING state.

    • Checks that the long-running command result indicates a timeout and specifies the respective Leaf Node as the source of the failure.

Error Propagation

  • Test case to verify error propagation for the Configure command of CSP and SDP Subarray Leaf Nodes. This test ensures that if either CSP or SDP subarray is identified as defective, and the Configure command is executed on the TMC Mid, the command reports an error.

Invalid Json

  • This scenario tests the rejection of invalid JSON inputs during the Configure command execution on a Telescope Monitoring and Control (TMC) system. It includes steps to set up the TMC, configure the subarray, and validate the rejection of various invalid JSON inputs.

Command Not Allowed

The following tests verify the command not allowed error propagation for the AssignResources command on various leaf nodes:

  • Command Not Allowed Exception Propagation from CSP, SDP, and Dish Leaf Nodes

    • Induces a command not allowed exception in the Leaf Nodes to simulate a failure scenario.

    • Verifies that the long-running command result indicates a failure and specifies the Leaf Node as the source of the failure.
