How do I test receive and fallback function

[samlak]

I have been able to test all other parts of my smart contract but I am unable to test the receive and fallback function. I have searched through the internet but I can't find a straightforward answer. I tried to test the fallback function using this code but it doesn't work.

  await expect(
     transportManager.sendTransaction({
        value: sendValue,
      })
  ).to.be.revertedWith("TransportManager__Fallback");

The test failed with this result

TypeError: transportManager.sendTransaction is not a function

How do I go about this? How can I test the receive and fallback function.

For the fallback you can send a function to the contract that doesn't exist

here's an awesome article that goes more indept

and for receive:

I'd imagine you just send ether directly to the contract

@samlak I managed to test both function. This is my repo: https://github.com/PacelliV/hardhat-fund-me. Let me if it works for you.
