I use Selenium WebDriver and Chrome to do feature testing in my app. I have already successfully setup multiple rails app with rspec, capybara and selenium, but I can't get why this one does not work.
Here's the problem: When I run the feature tests for the first time, it works according to plan. However, if I run it a second time, selenium crashes with the following message:
Selenium::WebDriver::Error::NoSuchDriverError: invalid session id (Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Mac OS X 10.14.3 x86_64)
I might add that feature tests work perfectly in other apps, so this is not a Chrome/chromedriver compatibility issue.
I have been working on this for days now and I cannot figure out what's happening
Here's my config:
- selenium-webdriver (3.141.0)
- capybara (2.7.1)
- Chrome 74 and chromedriver 74.0.3729.6

Chromedriver reuse the same session id over and over again over the tests. This is why the first time, the tests pass but if I start again, chromedriver will use the exact same session id which is what I think cause the problem. I logged Selenium's actions, and it does send DELETE so I don't understand.

I found what went wrong.
We are using a library to cache api response during test after they are made for the first time.
The problem is, the driver sends a request to get a session id. This is why the first time the tests were passing. The library cached the response from the driver which had the same session id everytime, hence the error from chrome.
If you're using such libraries (VCR, ephemeral_response) and get similar error this is something you might want to investigate
4The first thing I notice is that you're using a 3 year old version of Capybara with new versions of selenium-webdriver, Chrome, and chromedriver. Since selenium-webdriver doesn't follow SemVer expecting those to work correctly together is a stretch. You probably want to upgrade Capybara.
Often this error is caused by resource issues with Chrome. Since you appear to be running on MacOS that's not as likely as if you were running this in containers. However it wouldn't hurt to try adding the disable-dev-shm-usage chrome option, and/or setting the window size smaller to see if the error goes away. You could also just try a reboot.
Beyond that a couple of other potentials are
You have an after block registered that has already closed the session - comment out the after block and see if the issue goes away
A bug in chromedriver 74 (of which a few have been reported - , etc) - try rolling back to chrome and chromedriver 73 to see if the issue goes away
I had this error today and what worked for me was to downgrade the chromedriver version from latest to the version of chrome I have installed on my machine.
The invalid session ID error is a WebDriver error that occurs when the server does not recognize the unique session identifier. This happens if the session has been deleted or if the session ID is invalid.
