如何解决将 Pact 合约测试从 JavaScript 重写为 C#
如果这个问题违反了规则,我们深表歉意。
我有这个 js
课:
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# 中编写等效代码。除了 GET
之外,我已经完成了所有工作,不可否认,到目前为止我所做的可能还有很长的路要走。这是我到目前为止所拥有的:
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,*/*" }
}
})
.WillRespondWith(new ProviderServiceResponse
{
Status = 200,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
?
解决方法
做什么
var consumer = new SomethingApiClient(_mockProviderServiceBaseUri);
...
var result = consumer.GetSomething("tester");
做什么?
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,它应该是您创建的用于与提供者通信的 API 客户端。
请参阅 https://github.com/pact-foundation/pact-workshop-dotnet-core-v1/blob/master/CompletedSolution/Consumer/src/ConsumerApiClient.cs 以获取可以从您的 JS 代码替换 axios 客户端的示例 API 客户端。
