将 Pact 合同测试从 JavaScript 重写为 C#

Question

如果这个问题违反了规则，我们深表歉意。

我有这个 js class:

src/get.js

const { get } = require('axios')

module.exports = function () {
    return get(`http://localhost:1234/token/1234`)
}

还有这个测试：

consumer.pact.js

const path = require("path")
const chai = require("chai")
const { Pact, Matchers } = require("@pact-foundation/pact")
const chaiAsPromised = require("chai-as-promised")
const expect = chai.expect
chai.use(chaiAsPromised)
const { string } = Matchers
const get = require('../src/get')

describe('Consumer Test', () => {
    const provider = new Pact({
        consumer: "React",
        provider: "token",
        port: 1234,
        log: path.resolve(process.cwd(), 'logs', 'pact.log'),
        dir: path.resolve(process.cwd(), 'pacts'),
        logLevel: "INFO"
    });

    before(() => provider.setup()
    .then(() => provider.addInteraction({
        state: "user token",
        uponReceiving: "GET user token",
        withRequest: {
            method: "GET",
            path: "/token/1234",
            headers: { Accept: "application/json, text/plain, */*" }
        },
        willRespondWith: {
            headers: { "Content-Type": "application/json" },
            status: 200,
            body: { "token": string("bearer") }
        }
    })))

    it('OK response', () => {
        get()
        .then((response) => {
            expect(response.statusText).to.be.equal('OK')
        })
    })

    after(() => provider.finalize())
})

我正在尝试使用 js 代码和示例 here 在 C# 中编写等效项。除了 GET 之外，我已经完成了所有工作，诚然，到目前为止我所做的可能还有很长的路要走。这是我目前所拥有的：

ConsumerTest.cs

//using NUnit.Framework;
using System.Collections.Generic;
using PactNet;
using PactNet.Mocks.MockHttpService;
using PactNet.Mocks.MockHttpService.Models;
using Xunit;

namespace PactTests.PactTests
{
  public class ConsumerTest : IClassFixture<ConsumerPact>
  {
    private IMockProviderService _mockProviderService;
    private string _mockProviderServiceBaseUri;

    public ConsumerTest(ConsumerPact data)
    {
      _mockProviderService = data.MockProviderService;
      _mockProviderService.ClearInteractions(); //NOTE: Clears any previously registered interactions before the test is run
      _mockProviderServiceBaseUri = data.MockProviderServiceBaseUri;
    }

    [Fact]
    public void OKResponse()
    {
      //Arrange
      _mockProviderService
        .Given("user token")
        .UponReceiving("GET user token")
        .With(new ProviderServiceRequest
        {
          Method = HttpVerb.Get,
          Path = "/token/1234",
          Headers = new Dictionary<string, object>
          {
            { "Accept", "application/json, text/plain, */*" }
          }
        })
        .WillRespondWith(new ProviderServiceResponse
        {
          Status = 200,
          Headers = new Dictionary<string, object>
          {
            { "Content-Type", "application/json" }
          },
          Body = new //NOTE: Note the case sensitivity here, the body will be serialised as per the casing defined
          {
            token = "bearer"
          }
        }); //NOTE: WillRespondWith call must come last as it will register the interaction

        var consumer = new SomethingApiClient(_mockProviderServiceBaseUri);

      //Act
      var result = consumer.GetSomething("tester");

      //Assert
      Assert.Equal("tester", result.id);

      _mockProviderService.VerifyInteractions(); //NOTE: Verifies that interactions registered on the mock provider are called at least once
    }
  }
}

ConsumerPact.cs

using PactNet;
using PactNet.Mocks.MockHttpService;
using System;

namespace PactTests.PactTests
{
  public class ConsumerPact : IDisposable
  {
    public IPactBuilder PactBuilder { get; private set; }
    public IMockProviderService MockProviderService { get; private set; }

    public int MockServerPort { get { return 1234; } }

    public string MockProviderServiceBaseUri { get { return String.Format("http://localhost:{0}", MockServerPort); } }

    public ConsumerPact()
    {
      // Pact configuration
      var pactConfig = new PactConfig
      {
        SpecificationVersion = "2.0.17",
        PactDir = @"Users/paulcarron/git/pact/pacts",
        LogDir = @"Users/paulcarron/git/pact/logs"
      };

      PactBuilder = new PactBuilder(pactConfig);

      PactBuilder
        .ServiceConsumer("React")
        .HasPactWith("token");

      MockProviderService = PactBuilder.MockService(MockServerPort);

    }

    public void Dispose()
    {
      PactBuilder.Build();
    }
  }
}

我该怎么做GET？

Answer 1

什么

var consumer = new SomethingApiClient(_mockProviderServiceBaseUri);
...
var result = consumer.GetSomething("tester");

做吗？

那应该是执行 HTTP GET 的 API 客户端代码。任何 HTTP 客户端库都可以完成这项工作，但重要的是，它应该是您创建的 API 客户端，用于与您的提供商通信。

请参阅 https://github.com/pact-foundation/pact-workshop-dotnet-core-v1/blob/master/CompletedSolution/Consumer/src/ConsumerApiClient.cs 示例 API 可以从您的 JS 代码中替换 axios 客户端的客户端。
