Acceptance test flaking only in CI

[Vir-8]

Hey, I'm writing an acceptance test for topic management in this PR, it's failing at a certain point only in CI, with me having no clear way of reproducing it.

It works perfectly fine and executes correctly on my local environment, and other very similar functionalities work fine on CI too. I have no clue what the issue is yet, but it always seems to fail in CI. I'm hard-stuck and would really appreciate any help.

See this debugging doc for more info -

Vir, before pushing onto CI , did you check the tests in headless mode?
In my case, whenever the test passes either of the modes (headless and non-headless) locally then it passes over CI as well.

Hope this helps.

[Vir-8]

Yes, it passes in headless mode as well.
I just used the --headless flag for context instead of the method you mentioned below

[Akhilesh-max]

Running in headless mode, is as simple as toggling the Envirronment variable process.env.HEADLESS in puppeteer.utils.ts file.

@Vir-8 For posterity, what was the fix?

[Vir-8]

It was simply waiting for a selector to be visible that was being evaluated, added solution to the debugging doc.

Ah thanks, interesting. So why would it pass on your local machine ... any idea?

[Vir-8]

Not exactly sure, but possibly CI being slightly slower comparatively so it wasn't necessary to wait locally but necessary to wait on CI.
