我正在尝试使用Typescript实现pact-node. (https://github.com/pact-foundation/pact-node).我遇到一些问题,导致的错误消息描述性不是很高.可能是我在设置中做错了某些事情,在线提供的许多文档和示例都使用pact.js,并且存在一些差异.下面是我的代码:
const path = require('path');
import { Pact } from '../../../node_modules/@pact-foundation/pact';
import { Interaction, InteractionObject } from '../../../node_modules/@pact-foundation/pact';
import { expect } from 'chai';
import { afterEach, before, beforeEach, describe, it, after } from 'mocha';
import { myService } from '../../main/typescript/service/test-service';
describe('My Pact Test', () => {
const port = 5428;
let service: myService;
const provider = new Pact({
port,
log: path.resolve(process.cwd(), 'logs', 'pact.log'),
dir: path.resolve(process.cwd(), 'pacts'),
spec: 2,
consumer: 'MyConsumer',
provider: 'MyProvider',
pactfileWriteMode: 'merge',
});
const EXPECTED_BODY = [{
'auctionStartTime': 1549652248000,
'auctionEndTime': 1549911448000,
'resolveTime': 1539670248000,
'openTimestamp': 1533496996000,
'closeTimestamp': 1547804158000,
'previewStartTime': 1549393048000,
}];
before(() => provider.setup());
after(() => provider.finalize());
afterEach(() => provider.verify());
describe ('should get items ', () => {
console.log ('message 1 ');
before(() => {
console.log ('message 2');
return provider.addInteraction({
state: 'item present in database,
uponReceiving: 'a request for items',
withRequest: {
method: 'GET',
path: 'path_to_my_api_endpoint,
headers: {
Accept: 'application/json',
},
},
willRespondWith: {
status: 200,
headers: {
'Content-Type': 'application/json',
},
body: EXPECTED_BODY,
},
});
});
it('returns the correct response', (done) => {
console.log ('message 3');
service.getInfo('123', '123')
.then((response: any) => {
expect(response.data).to.eql(EXPECTED_BODY);
done();
});
});
});
})
但是,当我尝试运行此命令时,出现以下错误:
1) My Pact Test "before all" hook:
Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
2) My Pact Test "after all" hook:
Error: Failed to get the current sub/segment from the context.

有人知道我在做什么错吗?否则,有没有人举过使用打字稿实现契约的例子?
谢谢!
解决方法:
您没有使用https://github.com/pact-foundation/pact-js的原因吗?
Pact Node是一个较低级别的库,可能不适合您的工作. Pact JS是您创建的用于测试的高级DSL.
那里有一个TypeScript示例.
更新:您可能需要增加超时时间,看来您的系统启动模拟服务器所花费的时间超过2秒,并且正在运行.
描述的第二个错误看起来与公约无关.
