How to automatically migrate the development and test databases with `rails db:migrate` and Spring?

Question

I understand that rails db:migrate only affects the development database.

When running rspec with guard-rspec and spring, the test environment doesn't automatically apply migrations. Instead, you have to have guard fail, manually run RAILS_ENV=test rails db:migrate, and run your rspec guard again. This is expected behavior according to this issue: https://github.com/rails/rails/issues/25804

How could I make it so that either rails db:migrate does so for both environment at once, or have spring rspec automatically run pending migrations for the test environment as well?

I'd rather avoid a bash/zsh/shell alias because it has to be set up manually on everyone's machine.

As @stuart said in the comments, the only way is to either RAILS_ENV=test rails db:migrate && RAILS_ENV=development rails db:migrate or rails db:migrate db:test:prepare.
