由于某种原因，我的摩卡测试无法找到我的IDL。我得到了下面的错误：

它被正确地生成并保存在我的目标IDL文件夹（../solana-anchor-reactjs-payment/target/idl/payment.json）中，下面是IDL文件的内容：

调用此IDL的测试如下所示（../solana-anchor-reactjs-payment/tests/payment-test.ts）：

import * as anchor from '@project-serum/anchor';
import { Program } from '@project-serum/anchor';
import {Payment} from "../target/types/payment";
import * as assert from "assert";

describe('send payment message', () => {
    // Configure the client to use the local cluster.
    anchor.setProvider(anchor.Provider.env());

    const program = anchor.workspace.Payment as Program<Payment>;

    it('can send a new payment', async () => {
        // Call the "SendTweet" instruction.
        const payment = anchor.web3.Keypair.generate();
        await program.rpc.sendPayment('veganism', {
            accounts: {
                paymentState: payment.publicKey,
                sender: program.provider.wallet.publicKey,
                systemProgram: anchor.web3.SystemProgram.programId,
            },
            signers: [payment],
        });

        //Fetch the account details of the payment sender
        const senderAccount = await program.account.paymentState
            .fetch(payment.publicKey);

        assert.ok(senderAccount.timestamp);
        assert.equal(senderAccount.sender.toBase58(), program.provider.wallet.publicKey.toBase58())
        assert.ok(senderAccount.note, 'Starbucks Coffee');
        assert.ok(senderAccount.amount, '8');
        assert.fail(senderAccount.amount, 200);
    });
});

有可能测试无法访问IDL所在的文件夹。所以我甚至物理地将其复制到与测试相同的文件夹中，但这仍然没有成功。对此的任何帮助都将不胜感激，提前感谢。

Update这并不理想，但你可以通过解析idl json文件，然后将其作为一个对象传递到程序中来解决这个问题。你可以添加以下行来设置程序：

// Read the generated IDL.
const idl = JSON.parse(
    require("fs").readFileSync("./target/idl/payment.json", "utf8")
);

//Address of the deployed program
const programId = new anchor.web3.PublicKey("8BBGEacFKQ1dYDPF39HstjAC2195iV1ta9scv1WxtJfT");

//Generate the program client from IDL
const program = new anchor.Program(idl, programId);
