如何对具有多个约定的本地网运行近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jest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，显然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 node_modules/near-api-js/lib/account.js:83:23
      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)

看起来near-js-api也被硬编码为只部署一个契约。我需要测试多个合约。如何部署多个合同？来自near-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',
        };

如何部署多个合同？

您可以使用与test_environment.js相同的masterAccount.createAndDeployContract。除了一些常见的init之外，这里没有什么特别的--你可以直接创建你的测试所需要的任何账户/契约。

near-js-sdk本身正在针对神秘的共享测试进行部署。

这是可用于运行集成测试的共享网络。除非你想让你的开发工作保持私密性--这是运行测试的推荐方式(因为这是目前可用于测试的最现实的环境)。

但是，显然缺少如何在本地节点上创建测试帐户的步骤。

如果您使用create-near-app创建项目，那么在neardev/项目文件夹中可能已经有了相应的test.near密钥。这就是为什么上面的神秘环境通常是开箱即用的。

对于您的本地环境，您需要自己创建test.near：

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

在此之后，您可以将密钥复制为本地格式(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
