Contribution guide's "Writing Tests" link to repo is broken

[hbar1st]

Describe the Issue

In the fCC contribution guide section on Writing Tests here https://contribute.freecodecamp.org/how-to-work-on-coding-challenges/#writing-tests the link to the curriculum-helpers repo is invalid (shows a 404 page).
The specific line that links to it is:

The available functions are defined in the curriculum-helpers repo.

I believe the link should be updated to something else, but I'm not sure exactly what.

Affected Page

https://contribute.freecodecamp.org/how-to-work-on-coding-challenges/#writing-tests

Steps to Reproduce

Click on the link "curriculum helpers" to see the 404 page.

Recommended fix or suggestions

please update the link to something that is relevant or the intended page.

could you please share a screen recording

hi again @Jeevankumar-s , I am not sure why you want a screen recording? I simply clicked the link and saw a 404 message as I shared above.
Not sure how a video will help.

Hi @hbar1st, I asked for a screen recording just to check if there’s any difference in how the link behaves on your side (like caching, redirects, or permissions). It’s opening the correct repo page for me, so the recording would help understand where it might be breaking.

Hi @hbar1st, I think I see what's happening. I copied the link manually, and the file (lib/ index. ts) doesn't actually exist, so it should return a 404. But on the GitHub mobile app, it redirects me to the repo's home page instead of showing the 404, which is why it looked like it was working on my side.

Yes, we should update the link 👍

The correct link value should be:
https://github.com/freeCodeCamp/curriculum-helpers/blob/main/packages/helpers/lib/index.ts
