Does expectCall work when the count is zero?

[PaulRBerg]

i.e. like this:

vm.expectCall(
  callee: address(someAddress),
  data: abi.encodeCall(token.transfer, (alice, 10)),
  count: 0
);

Would this fail the test if there's at least 1 call made?

Yes, it would fail. The count is used as a strict parameter.

Good to know! I've also seen this in the docs now:

count can also be set to 0 to assert that a call is not made
