nearprotocol - 如何针对具有多个契约(Contract)的本地网络运行近 js-api 测试

Question

我已经设置了节点:

nearup run localnet --binary-path ~/code/nearcore/target/release

我正在尝试运行一个开玩笑的测试用例:

beforeAll(async function () {
  // NOTE: nearlib and nearConfig are made available by near-cli/test_environment
  const near = await nearlib.connect(nearConfig)
})

但是，很明显缺少如何在本地节点上创建测试帐户的步骤。这是错误:

 ● Test suite failed to run

    Can not sign transactions for account test.near, no matching key pair found in Signer.

      at Object.exponentialBackoff [as default] (node_modules/near-api-js/lib/utils/exponential-backoff.js:7:24)

      at LocalTestEnvironment.setup (node_modules/near-cli/test_environment.js:39:9)

也长得像 near-js-api硬编码以仅部署一份合约。我需要测试多个契约(Contract)。如何部署多个合约？来自近 js-api test_environment.js

class LocalTestEnvironment extends NodeEnvironment {
    constructor(config) {
        super(config);
    }

    async setup() {
        this.global.nearlib = require('near-api-js');
        this.global.nearAPI = require('near-api-js');
        this.global.window = {};
        let config = require('./get-config')();
        this.global.testSettings = this.global.nearConfig = config;
        const now = Date.now();
        // create random number with at least 7 digits
        const randomNumber = Math.floor(Math.random() * (9999999 - 1000000) + 1000000);
        config = Object.assign(config, {
            contractName: 'test-account-' + now + '-' + randomNumber,
            accountId: 'test-account-' + now + '-' + randomNumber
        });
        const keyStore = new nearAPI.keyStores.UnencryptedFileSystemKeyStore(PROJECT_KEY_DIR);
        config.deps = Object.assign(config.deps || {}, {
            storage:  this.createFakeStorage(),
            keyStore,
        });
        const near = await nearAPI.connect(config);

        const masterAccount = await near.account(testAccountName);
        const randomKey = await nearAPI.KeyPair.fromRandom('ed25519');
        const data = [...fs.readFileSync('./out/main.wasm')];
        await config.deps.keyStore.setKey(config.networkId, config.contractName, randomKey);
        await masterAccount.createAndDeployContract(config.contractName, randomKey.getPublicKey(), data, INITIAL_BALANCE);

        await super.setup();
    }

Near-js-sdk 本身正在针对神秘的共享测试进行部署

    case 'ci':
        return {
            networkId: 'shared-test',
            nodeUrl: 'https://rpc.ci-testnet.near.org',
            masterAccount: 'test.near',
        };

How can I deploy multiple contracts?

您可以使用 masterAccount.createAndDeployContract同 test_environment.js .除了一些常见的 init 之外，没有什么特别的 - 您可以直接创建测试所需的任何帐户/契约(Contract)。

near-js-sdk itself is deploying against mysterious shared-test

这是可用于运行集成测试的共享网络。除非您想将您的开发工作保密 - 推荐运行测试的方式(因为点击当前可用于测试的最现实的环境)。

However there is obvious step missing how to create test accounts on your local node.

如果您使用 create-near-app 创建项目您可能有相应的 test.near key 在 neardev/项目文件夹已经。这就是为什么上述神秘环境通常开箱即用的原因。
对于您的本地环境，您需要创建 test.near你自己:

NODE_ENV=local near create-account test.near --masterAccount some-existing-account

之后，您可以将 key 复制到本地格式(或仅重新配置 UnencryptedFileSystemKeyStore 以使用 ~/.near-credentials 路径):

cp ~/.near-credentials/local/test.near.json project/dir/neardev/local/test.near.json
