Description

In this commit, we introduce unit tests for both the MutatingAdmission and ValidatingAdmission webhooks specifically for the FederatedHPA resource.

The tests include:

  • Validation webhook tests:

    • Verifies that admission is denied with an appropriate error message when decoding the request object fails.
    • Ensures admission is denied when the FederatedHPA spec contains invalid values, such as a minReplicas set to zero, and the correct error message is returned.
    • Confirms that a valid FederatedHPA object is allowed through without errors.
  • Mutation webhook tests:

    • Verifies that admission is denied when decoding the request object fails, returning the appropriate error message.
    • Ensures that the FederatedHPA object is correctly mutated when provided with default values, including scale policies and CPU utilization.
    • Confirms that no patches are applied when the FederatedHPA object is handled correctly and that admission is allowed for valid FederatedHPA objects.
