Is it possible to send ether to a contract after deployment inside a test?

[xrd]

This is using Hardhat with ethers.js:

My test wants to deploy a contract and then I want to send ether to it:

const { ethers } = require("hardhat");
describe("HandleEther contract", function () {
  let factory;
  let contract;
  let owner;
  let addr1;

  beforeEach(async function () {
    factory = await ethers.getContractFactory("HandleEther");
    [owner, addr1] = await ethers.getSigners();
    contract = await factory.deploy();
  });

  // You can nest describe calls to create subsections.
  describe("Deployment", function () {
    it("Should send ether to contract after deployment", async function () {
        const params = { from: owner,to: addr1, value: ethers.utils.parseUnits("1", "ether").toHexString()};
        const txHash = await owner.provider.sendTransaction(params);
        console.log("transactionHash is " + txHash);  
    });
  });
});

When I run npx hardhat test, I see this:

$ npx hardhat test

My contract contracts/HandleEther.sol looks like this:

pragma solidity ^0.8.7;
contract HandleEther {
    constructor() payable {
    }
}

My hardhat.config.js:

require("@nomiclabs/hardhat-waffle");

/**
 * @type import('hardhat/config').HardhatUserConfig
 */
module.exports = {
  solidity: "0.8.7",
};

My package.json is:

{
  "name": "hardhat-simplified",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "dependencies": {
    "hardhat": "^2.6.0"
  },

  }
}

Hey @xrd just replace owner with owner.address and addr1 with addr1.address.

Hi @zemse , thanks for the comment. I get more or less the same error:

npx hardhat test

$ cat test/SendEtherToContract.js 
const { ethers } = require("hardhat");
describe("HandleEther contract", function () {

  beforeEach(async function () {
    const abi = [
        "constructor()",
    ];
    factory = await ethers.getContractFactory("HandleEther");
    [owner, addr1] = await ethers.getSigners();
    contract = await factory.deploy();
  });

  // You can nest describe calls to create subsections.
  describe("Deployment", function () {
    it("Should send ether to contract after deployment", async function () {
        const params = { from: owner.address,to: addr1.address, value: "1" };
            // ethers.utils.parseUnits("1", "ether").toHexString()};
        const txHash = await owner.provider.sendTransaction(params);
        console.log("transactionHash is " + txHash);  
    });
  });
});

Oh I see, I did not notice that,

// remove the from owner
const params = { to: addr1, value: ethers.utils.parseUnits("1", "ether").toHexString()};
// remove the .provider
const txHash = await owner.sendTransaction(params);

[xrd]

If I use addr1.address then it works! Thank you.
