This test is meant to verify the validation fix, but it only checks "was the green-painting function called?". That same function also gets called by the other new block (the operator-add code above), so this test would still pass even if the validation fix were removed entirely. In other words, it does not actually test the change it is paired with.

Checking the operator's actual final border color would test the real behavior.

vi.spyOn(workflowStatusService, "getCurrentStatus").mockReturnValue(cachedCompleted);
vi.spyOn(validationWorkflowService, "validateOperator").mockReturnValue({ isValid: true });
const changeOperatorStateSpy = vi.spyOn(jointUIService, "changeOperatorState");

workflowActionService.addOperator(mockScanPredicate, mockPoint);

component.paper,
mockScanPredicate.operatorID,

This checks "was the red-painting function called?", but calling it is not enough on its own: red also has to be the color that actually ends up on the operator (see my note on the validation handler about the ordering). The test does not confirm the operator ends up red, so it would not catch the timing problem described there.

Checking the final border color would make this test reliable.

vi.spyOn(workflowStatusService, "getCurrentStatus").mockReturnValue(cachedCompleted);
vi.spyOn(validationWorkflowService, "validateOperator").mockReturnValue({ isValid: false, messages: {} });
const changeOperatorColorSpy = vi.spyOn(jointUIService, "changeOperatorColor");

workflowActionService.addOperator(mockScanPredicate, mockPoint);
fixture.detectChanges();

// The handleOperatorValidation subscription must take the invalid branch,
// which paints red via changeOperatorColor and never calls
// changeOperatorState. (The earlier state-color paint from the operator
// add stream is still made, but the final visible border is red because
// validation runs after.)
expect(changeOperatorColorSpy).toHaveBeenCalledWith(component.paper, mockScanPredicate.operatorID, false);
});
});
});
});
