I created a basic hardhat sample project. When I do npx hardhat test , Hardhat is running the out of the box test in scripts/sample-script.js (which supposedly is the deployment pipeline) and hardhat is NOT running my test which is in test/sample-test.js How do I fix this? How do I tell hardhat where my tests are? Below is my test file sample-test.js:

describe("NFTMarket", function() {
  it("Should create and execute market sales", async function() {
    /* deploy the marketplace */
    const NFTMarketplace = await ethers.getContractFactory("NFTMarketplace")
    const nftMarketplace = await NFTMarketplace.deploy()
    await nftMarketplace.deployed()

    let listingPrice = await nftMarketplace.getListingPrice()
    listingPrice = listingPrice.toString()

    const auctionPrice = ethers.utils.parseUnits('1', 'ether')

    /* create two tokens */
    await nftMarketplace.createToken("https://www.mytokenlocation.com", auctionPrice, { value: listingPrice })
    await nftMarketplace.createToken("https://www.mytokenlocation2.com", auctionPrice, { value: listingPrice })

    const [_, buyerAddress] = await ethers.getSigners()

    /* execute sale of token to another user */
    await nftMarketplace.connect(buyerAddress).createMarketSale(1, { value: auctionPrice })

    /* resell a token */
    await nftMarketplace.connect(buyerAddress).resellToken(1, auctionPrice, { value: listingPrice })

    /* query for and return the unsold items */
    items = await nftMarketplace.fetchMarketItems()
    items = await Promise.all(items.map(async i => {
      const tokenUri = await nftMarketplace.tokenURI(i.tokenId)
      let item = {
        price: i.price.toString(),
        tokenId: i.tokenId.toString(),
        seller: i.seller,
        owner: i.owner,
      return item
    console.log('items: ', items)

and here is my deployment pipeline, sample-script.js

const hre = require("hardhat");

async function main() {
  // We get the contract to deploy
  const Greeter = await hre.ethers.getContractFactory("Greeter");
  const greeter = await Greeter.deploy("Hello, Hardhat!");

  await greeter.deployed();

  console.log("Greeter deployed to:", greeter.address);

  .then(() => process.exit(0))
  .catch((error) => {

Update: Your test file looks OK and it runs on my env; Hardhat config docs explains how to configure test path, the default is test but make sure it's not configured otherwise in your hardhat.config.js -

module.exports = {
  paths: {
    sources: "./contracts",
    tests: "./test",
    cache: "./cache",
    artifacts: "./artifacts"

Try to run npx hardhat test test/sample-test.js and see if it does anything.

Your filename should be test/sample-test.js, if it already is, then your test file is invalid. Find the error and it'll work.

  • I'm sorry, could you rephrase that? My file, as I said above, is called sample-test.js, which is in the test/ folder. So test/sample-test.js. 'Find the error'.... there is no error. it's running the test. But one from the wrong directory.

  • That's what you assume... post the test script as I request and I'll be able to examine it.

  • btw above you said that the test file is called test/sample-test, that's why I was making sure it has the js extension.

  • indeed, thanks for pointing that out. just added a bit more depth to the explanation. In summary I just want to know where does hardhat define what is the path to test files. I find very weird that the tests are ran from the scripts folder out-of-the-box, but it does make sense that one could include tests in the deployment pipeline.

  • Looks OK and it runs on a new project, did you try to run npx hardhat test test/sample-test.js? Let me know if it works

I was able to solve this by

  1. adding to the npm package.json file a field defining explicitly the paths for testing with:

paths: { sources: "./contracts", tests: "./test", cache: "./cache", artifacts: "./artifacts" },

  1. uninstalling all deps and dev-deps. reinstalling the normal dependencies first and then the devDependencies with these commands in this order:

npm install

npm install -D

Running npx hardhat test now points to tests instead of scripts. More info in https://hardhat.org/config/#path-configuration

  • The paths shouldn't be in package.json, they should be in hardhat.config.js as I've written in my answer
