BUG: Selenium::WebDriver::Error::TimeoutError
Describe the bug
We occasionally get test flake on CI with Selenium::WebDriver::Error::TimeoutError
. It looks like Selenium is timing out when trying to get about:blank
inside within_about_blank_context
. I'm going to see if I can increase the timeout, since right now it's only 1 second, but I'm wondering if this is something that should be handled somehow inside of the gem.
Environment Happening In
- [ ] Production
- [ ] QA
- [X] Dev
To Reproduce
I don't have a great way to reproduce it, unfortunately. Basically, you need to run it lots of times on CI (we run it on every button or link click). One thing to note is that it only seems to happen very early in the test, like on the login page. We do have assertions to ensure that our page is fully loaded before running be_axe_clean
. Here is the error and stack trace:
1.1) Failure/Error: expect(page).to be_axe_clean.skipping(*a11y_skip)
Selenium::WebDriver::Error::TimeoutError:

Expected behavior
Consistently executing accessibility checks.
Actual behavior
Something like 5-10% of builds fail due to one of the tests getting this timeout.

Okay, I was trying to figure out where that "1000 ms" was coming from, and realized you set it inside your code. So I can't really control that. Not sure if it will do any good, but I might try navigating to a blank page at the beginning of each test to make sure about:blank
can load quickly.
Welp, that didn't work either. It looks like the timeout was added in #315, but it's not clear to me why it was needed.
