“无法通过节点在Mocha测试中使用Wolkenkit客户端获取配置”

Question

我正在尝试通过Node中的Mocha测试与Wolkenkit应用程序进行交互。

跟随tutorial on client connections，在运行测试时，出现以下错误：

Error: Failed to get configuration.
  at ConfigurationWatcher.wentOffline (node_modules/wolkenkit-client/dist/ConfigurationWatcher.js:113:28)
  at /home/aef/Projects/experiments/wolkenkit_bullet/node_modules/wolkenkit-client/dist/ConfigurationWatcher.js:101:16
  at tryCatch (node_modules/es6-promise/dist/es6-promise.js:409:12)
  at invokeCallback (node_modules/es6-promise/dist/es6-promise.js:424:13)
  at publish (node_modules/es6-promise/dist/es6-promise.js:398:7)

  at flush (node_modules/es6-promise/dist/es6-promise.js:128:5)
  at processTicksAndRejections (internal/process/task_queues.js:79:11)

非常感谢您提供解决此问题的帮助。

我在package.json中添加了以下依赖项：

"devDependencies": {
  "chai": "^4.2.0",
  "mocha": "^7.0.1"
},
"dependencies": {
  "wolkenkit": "^3.1.2",
  "wolkenkit-client": "^3.1.0"
},

我的测试代码如下：

'using strict';

const expect = require('chai').expect;
const wolkenkit = require('wolkenkit-client');

describe("wolkenkit app", () => {
    it("first test", async () => {
        const app = await wolkenkit.connect({host: 'local.wolkenkit.io', port: 3000});
    });
})

此错误可能是由您的本地自签名证书引起的。客户端无法连接到后端，因为它不信任此证书。您可以像这样使用process.env.NODE_TLS_REJECT_UNAUTHORIZED标志来绕过此检查…

process.env.NODE_TLS_REJECT_UNAUTHORIZED = 0;

suite('integration', () => {
  let application;

  suiteSetup(async () => {
    application = await wolkenkit.connect({ host: 'local.wolkenkit.io', port: 3000 });
  });

另一种选择是将证书添加到您信任的证书中。
