Refactor request tests for clarity and structure - #7447
Conversation
Issues Found: 1. Incorrect error expectation in app2 test The test expects a 500 error with message containing "not a function" or "has no method", but the error message might be different in modern Node.js versions. 2. Missing error handling in middleware Some routes don't handle errors properly. 3. Potential race condition in async tests Using after(2, done) without ensuring both calls complete properly. 4. Inconsistent test structure Some tests use .expect() with multiple arguments incorrectly.

Worthless AI slop full of lies; waste of our time.
- Incorrect error expectation in app2 test The test expects a 500 error with message containing "not a function" or "has no method", but the error message might be different in modern Node.js versions.
How can the error be different in modern Node.js versions if it isn't? It can be verified by running tests on modern Node.js versions like the CI does.
- Missing error handling in middleware Some routes don't handle errors properly.
Ah, yes. Relying on the Express default error handler in Express tests is definitely a mistake. Not like this is a deliberate functionality of the framework.
- Potential race condition in async tests Using after(2, done) without ensuring both calls complete properly.
??? The author of this PR (some kind of an LLM) probably did not bother to look what after does and did not decide to think for up to 5 seconds to deduce it from the code.
- Inconsistent test structure Some tests use .expect() with multiple arguments incorrectly.
All .expect() calls changed in this PR were correct.
| var after = require('after') | ||
| var express = require('../') | ||
| , request = require('supertest'); | ||
| var request = require('supertest'); |
| .expect(200) | ||
| .expect('name=tobi', done); |

The .expect(200) is ok, but not really necessary. If Express changed the default status code other tests would also catch it.
Otherwise it's just a formatting change.
| var app2 = express() | ||
| var cb = after(2, done) | ||
|
|
||
|
|
| // This should fail because foobar doesn't exist on app2's request | ||
| try { | ||
| res.send(req.foobar()) | ||
| } catch (err) { | ||
| res.status(500).send(err.message) | ||
| } |

Yes, it should fail and Express should automatically do what was added here.
The try/catch is completely unnecessary, because Express (or router in 5.x) catches errors and forwards them to the error handling middleware, which in this case is the default error handler:

This is just after(2, done), but worse.
