deploy

[Naveed-Jameel]

in some cases first we deploy contract and then use contract instance and vice versa ?

1. await deployements.fixture(["all"]);
   fundMe=await ethers.getContract("FundMe")

fundMe=await ethers.getContract("FundMe");
myContract=await fundMe.deploy();

Hey @Naveed-Jameel please elaborate further the question you want to ask.

@Naveed-Jameel : ^ Exactly!

Code snippets (examples work too) for both scenarios 1 and 2 please.

I assume, you want to know the differences between 1 and 2 scenarios, if it is that what you want, here's an explanation for you:

1. In the first scenario you are using hardhat-deploy which is a Plugin for replicable deployments. Tests can use the deployments.fixture function to run the deployment and snapshot it so that tests don't need to perform all the deployment transactions every time. They can simply reuse the snapshot for every test.

• So you are executing deployment as fixture for test in the first line await deployements.fixture(["all"]); and then getting FundMe contract instance is the second line.

2. In the second scenario you are getting the FundMe contract instance and then deploying the contract by myContract=await fundMe.deploy(); which is a function for deploying contracts using hardhat-ethers plugin. It will start the deployment, and return a Promise that resolves to a Contract.

• Deploying with this method means that at the beginning of each test you are deploying your contract.

Btw your question can be drastically improved and you should consider that.
