Rails 7 system test on WIndows 10 - certificate verify failed

Question

On Windows 10, with a new Rails 7 application and an empty system test, when I run the system test:

rails test test/system/empty_test.rb, I got following error:

C:/Ruby30-x64/lib/ruby/gems/3.0.0/gems/net-protocol-0.1.2/lib/net/protocol.rb:46:in `connect_nonblock': SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate) (OpenSSL::SSL::SSLError)

I am not sure what certificate the code is looking for, it is just a new site and I locally access it from localhost:3000.

Here is the code for the empty system test:

require "application_system_test_case"

class EmptyTest < ApplicationSystemTestCase
end

I used the empty test just to make sure it is not the test code caused the error.

Here is my question:

Which certificate the rails system test is looking for?
How could I fix it?

Rails document should document this in System Testing section.

When we have System Testing with the default setting:

driven_by :selenium, using: :chrome, screen_size: [1400, 1400]

A system environment variable SSL_CERT_FILE should be defined.

I followed the answer in this thread:

Getting SSL error in ruby on Windows

It started to work right away.
