there are already tests for this component in packages/core/test/controls/numericInputTests.tsx. can you please move your new tests into that test suite?

it("Initial state should be empty string", () => {
const wrapper = mount(<NumericInput />);
const input = wrapper.find("input");

assert.strictEqual(input.prop("value"), "");
});

it("Should handle increment up to 21 decimal digits", () => {
const changeSpy = spy();
const wrapper = mount(
<NumericInput
onValueChange={changeSpy}
value={0}
stepSize={0.000000000000000001}
minorStepSize={0.000000000000000001}
/>,
);
const input = wrapper.find("input");

console.log(input.simulate("keydown", { key: "ArrowUp" }));

assert.isTrue(changeSpy.calledWith(0.000000000000000001));
});
});
