我已经构建了一个api，我想测试一些端点。
我有许多与以下测试相似的测试。它们都因Error: ECONNREFUSED: Connection refused
测试
import { assert, expect } from "chai";
import request from "supertest";
import app from "./../src/index";
describe("Authentication", () => {
it("should respond with 200 product_id is authorised", async () => {
const result = await request(app).post("/api/auth")
.send({
product_id: "123",
origin: "localhost:3000",
})
.expect("Content-Type", /json/)
.expect(200);
});
it("should respond with session token", async () => {
const result = await request(app).post("/api/auth")
.send({
product_id: "123",
origin: "localhost:3000",
});
expect(result.body.data).to.have.property("token");
});
});
package.json

错误：

显然连接被拒绝了吗？但是我不确定这到底意味着什么，因为您可以看到错误日志中的服务器已连接，mongo服务也已连接。
index.ts
import Server from "./server";
export default new Server().server;
server.ts
从“ ./app”导入应用；
class Server {
public server: any;
private instance: any;
private app: any;
private config: any;
constructor() {
this.instance = new App();
this.app = this.instance.app;
this.config = this.instance.config;
this.server = this.app.listen(this.config.port, this.config.hostname);
console.log("Server Running On: " + this.config.hostname + ":" + this.config.port);
}
}
export default Server;

来运行测试用例之前，请确保服务器已停止，因为supertest在同一端口中运行api。因此，您需要使该端口免费供supertest使用。
由于您正在测试文件中使用它，
supertest import request from "supertest";
import app from "./../src/index";
包含域URL，例如app，当您调用api之类的http://localhost:3135时，其中request(app).post指的是request模块，需要确保supertest是免费的。也就是说，app在端口request('http://localhost:3135').post上没有进程运行时起作用。
您可以使用3135（在Linux中）检查正在运行节点的进程，并终止每个进程以确保端口可用或终止该特定端口的进程。

我遇到了相同的错误，花了几个小时试图弄清楚是怎么回事。我正在使用$echo "node_modules" >> .gitignore
$git rm -r --cached node_modules
$git commit -am 'untracked node_modules'
库，因此碰巧它需要从环境变量中选择db选项。我的问题是我在错误的地方打了pg。
