我目前正在尝试使用mocha和NYC在我的固定路线上进行代码覆盖。

我已经尝试过预先检测代码，然后对检测到的代码运行测试，以及尝试以各种方式设置NYC以使其正常工作。

这是我当前的配置。先前所有代码都产生了相同的代码覆盖率输出）：

nyc配置

"nyc": {
  "extends": "@istanbuljs/nyc-config-typescript","extension": [
        ".ts",".tsx"
    ],"exclude": [
        "**/*.d.ts","**/*.test.ts"
    ],"reporter": [
        "html","text"      
    ],"sourceMap": true,"instrument": true
}

路由文件：

const routes = async (app: FastifyInstance,options) => {

  app.post('/code',async (request: FastifyRequest,response: FastifyReply<ServerResponse>) => {
    // route logic in here
  });
};

集成测试：

import * as fastify from fastify;
import * as sinon from 'sinon';
import * as chai from 'chai';

const expect = chai.expect;
const sinonChai = require('sinon-chai');
chai.use(sinonChai);

describe('When/code POST is called',() => {
  let app;

  before(() => {
    app = fastify();

    // load routes for integration testing
    app.register(require('../path/to/code.ts'));
  });
  after(() => {
    app.close();
  });

  it('then a code is created and returned',async () => {
    const {statusCode} = await apiTester.inject({
      url: '/code',method: 'POST',payload:{ code: 'fake_code' }
    });
    expect(statusCode).to.equal(201);
  });
});

我的单元测试调用如下所示：

nyc mocha './test/unit/**/*.test.ts' --require ts-node/register --require source-map-support/register --recursive

我实际上只为const routes =获得5％的代码覆盖率。我真的在想办法解决这个问题。任何帮助将不胜感激！我在这里研究过的其他解决方案都没有。
