rake db:test:prepare

Why is it necessary for me to run ‘rake db:test:prepare’ when I generate a new model?

Shouldn’t the ‘rake db:migrate’ also affect the test database? Why would anyone want to preserve the (broken) state of their test database?

Am I missing something?

it shouldn't be - if you run rake (which defaults to running rake test
or rake spec depending in your setup) it runs rake db:test:prepare for
you

Shouldn't the 'rake db:migrate' also affect the test database? Why would
anyone want to preserve the (broken) state of their test database?

In general it is easier to clone the test database from the
development database (via schema.rb) than try and replay migrations on
both, particularly for an older application with logs of migrations

I do this in my bashrc:

alias migrate=‘bundle exec rake db:migrate; RAILS_ENV=test bundle exec rake db:migrate;’

Not sure of the syntax but you get the idea. I don’t use rake or rake spec, and prefer running a guard/spork combo. Hence whenever I want to run a migration, I just run ‘migrate’ and that’s it.
