Http requests always returns 404

[digigarlab]

Hi there,

I am basically writing a network adapter between two http APIs, and I want to write some integration tests.

For now I have a very simple flow with 2 nodes:

• http in [POST /txmessage]
• http out [statusCode = 204, body = ""]

That was pretty trivial to implement with node-red and it's working fine (I can query my node-red instance with CURL and get the 204 message). However when I try to test this with the node-red-node-test-helper I always get a 404.

Here is the code I used:

const test = require("ava");
const got = require("got");
const helper = require("node-red-node-test-helper");
const nodeDebug = require("node-red/nodes/core/core/58-debug");
const nodeHttpIn = require("node-red/nodes/core/io/21-httpin");
const nodeHttpReq = require("node-red/nodes/core/io/21-httprequest");

helper.init(require.resolve("node-red"));

test.before.cb(t => {
  helper.startServer(t.end);
});

test.after.cb("cleanup", t => {
  helper.stopServer(t.end);
});

test.afterEach.always(async t => {
  await helper.unload();
});

test.cb("txmessagestatus", t => {
  t.plan(2);

  var flow = [
    {
      id: "12d2f142.f5953f",
      type: "tab",
      label: "txmessagestatus",
      disabled: false,
      info: ""
    },
    {
      id: "c8f9f191.d37fe",
      type: "http in",
      z: "12d2f142.f5953f",
      name: "",
      url: "/txmessagestatus",
      method: "post",
      upload: false,
      swaggerDoc: "",
      x: 150.90908813476562,
      y: 118.18181610107422,
      wires: [["47b2e0e1.e1e37", "35170c4f.2aade4"]]
    },
    {
      id: "47b2e0e1.e1e37",
      type: "http response",
      z: "12d2f142.f5953f",
      name: "",
      statusCode: "204",
      headers: {},
      x: 384.5454559326172,
      y: 118.18181037902832,
      wires: []
    },
    {
      id: "35170c4f.2aade4",
      type: "debug",
      z: "12d2f142.f5953f",
      name: "",
      active: true,
      tosidebar: true,
      console: false,
      tostatus: false,
      complete: "false",
      x: 395.9090881347656,
      y: 189.9999942779541,
      wires: []
    }
  ];

  const nodes = [nodeHttpIn, nodeHttpReq, nodeDebug];

  helper.load(nodes, flow, async () => {
    const client = got.extend({
      headers: {
        "Content-Type": "application/json"
      }
    });

    try {
      const res = await client.post(helper.url() + "/txmessagestatus");
      t.is(res.statusCode, 204);
      t.is(res.body, "");
    } catch (err) {
      // Always fail here, statusCode = 404
      t.fail(err);
    } finally {
      t.end();
    }
  });
});

Do you have any idea why this is not working? I couldn't find any recipe of integration testing with node-red and http in/out online, it would be great if someone could point to a fix or suggest another approach. Thanks.

Hi, I have the same issue by using the supertest API : helper.request().get("/").expect(200).end(done);

I always get a 404 .

same problem. how can we write integration tests involving NR's http in node? The test http requests originate outside, e.g. from a python or go program.
