Scenario

I want to use Rspec to build feature specs that test SR pages, just like normal web pages.

Therefore, I expect Capybara + Rspec to be able to do things like:

visit login_path
fill_in 'Email', with: user.email
fill_in 'Password', with: user.password + 'BAD'
expect(page).to have_content('That email or password is not correct')

How to use

In iTerm2, in the menu bar go to Scripts > Manage > New Python Script

Select Basic. Select Long-Running Daemon

Give the script a decent name (I chose auto_dark_mode.py)

Save and open the script in your editor of choice.
