How do I tell hardhat and waffle where my test is?

Question

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,
        tokenUri
      }
      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);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

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 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" },

2. 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
