Intermittent `WebDriverException: chrome not reachable` error on Windows runners.

[samcunliffe]

Stupid fix:

For the moment, one can simply rerun the windows (and any other cancelled) job(s). 🔨

Error message:

See, for example, this log.

 selenium.common.exceptions.WebDriverException: Message: chrome not reachable

Investigation:

Googling around it could be caused by:

• a chromedriver vs chrome incompatibility on one or more runners (!?)
• not waiting long enough,
• start-maximised or .. some other option (that you would think are unrelated).

Debugging thoughts dump:

• [x] Timeout option in conftest.py.
• [x] Spit out the chrome and chromedriver versions into the log files (if they're not already there).
• [ ] Try start-maximised in the tests/test_integration/conftest.py.
  • Don't run the server integration tests on Windows jobs?

I ran into a similar error while running pytest locally on my (silicon) Mac:

ERROR tests/test_integration/test_smoke.py::test_start_server_no_errors - selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://chromedriver.chromium.org/home

@niksirbi that is just a missing chromedriver (unrelated to Mac silicon) ... but It's not in the dev docs so my bad.

[samcunliffe]

Just for keeping the paper trail together: @niksirbi saw this which is a WebDriverException followed by some working tests with the chromedriver.

So it's really a timeout or startup problem (seems not likely to be related to versions of things).

Looks like this was solved by #96. Closing this for housekeeping reasons.
