import { Program } from "@coral-xyz/anchor";
import { Myproject } from "../target/types/myproject";
describe("myproject", () => {
// Configure the client to use the local cluster.
anchor.setProvider(anchor.AnchorProvider.env());
const program = anchor.workspace.Myproject as Program<Myproject>;
it("Is initialized!", async () => {
// Add your test here.
const tx = await program.methods.initialize().rpc();
console.log("Your transaction signature", tx);
});
});
2. Integration Testing: Deploy your smart contract to a local Solana cluster for integration testing. Anchor makes this easy with its built-in test utilities.
