Nock causes error when using a HTTPS_PROXY #2923
Description
Please avoid duplicates
- I checked all open bugs and none of them matched my problem.
Reproducible test case
https://github.com/SanderDeclerck/safe-chain-nock-bug
Nock Version
14.0.10
Node Version
v24.4.1
TypeScript Version
No response
What happened?
When the environment variable HTTPS_PROXY is set, it causes errors if nock is being used. The tests without nock run fine, but after requiring nock, tests start to fail.
In the linked repo, a minimal reproducible example can be found:
- tinyproxy is setup in the github actions workflow
- tests are run with HTTPS_PROXY set
dependencies
- nock@14.0.10
- axios@1.13.0
index.test.js
// Function under test
async function fetchData() {
const axios = require("axios");
const response = await axios.get("https://example.com/");
return response.status;
}
// Tests
describe("HTTP request test", () => {
test("without nock", async () => {
const result = await fetchData();
expect(result).toBe(200);
}, 20000);
test("with nock", async () => {
const nock = require("nock");
nock.disableNetConnect();
nock("https://example.com").get("/").reply(200);
const result = await fetchData();
expect(result).toBe(200);
}, 20000);
