What motivated this change?
We are currently working on allowing system tests to be run within a
Docker container. While system tests are usually ran in chrome headless
mode, it is useful to also be able to run the system tests with chrome
in the non-headless mode. However, running a GUI application from within
a docker container is not usually recommended and from our research
quite difficult. As such, we want to allow running system tests against
a remote browser.
For example, one can run a `chromedriver` server on localhost and then
configure Capybara to connect to the `chromedriver` from within the
container.
What does this change do?
This change adds support for a `CAPYBARA_REMOTE_DRIVER_URL` env variable
which will switch Capybara to use the remote driver instead of the
`chrome` driver. Currently, we expect the remote driver to be a
`chromedriver` server.
