Referring to how the other components do it but MatSlider is ValueMax / ValueMin / Step & MatNumeric is Maximum, Minimum and Step.

I would like to see it consistent across the components or since we only have 2 instances of "Max/Min/Step" that I found we can refer to material.io for the tie breaker?

**Material-UI uses step, min, max for their Slider - Which I think is best and suggest

The mock JSRuntime should support being cast to IJSInProcessRuntime and IJSUnmarshalledRuntime by implementing the interfaces, and providing additional setup and verify methods.
