Ran rake db:migrate after adding a new table and this is what happened:  
C:\my\_bigz\>rake db:migrate --trace  
(in C:/my\_bigz)  
\*\* Invoke db:migrate (first\_time)  
\*\* Invoke environment (first\_time)  
\*\* Execute environment  
\*\* Execute db:migrate  
\*\* Invoke db:schema:dump (first\_time)  
\*\* Invoke environment  
\*\* Execute db:schema:dump

…nothing

Why?

just a hunch - did you clone your db structure to test?

imac:~/Documents/dev/ivmc jodi$ rake --tasks | grep clone

rake db:test:clone # Recreate the test database  
from the current environment’s database schema  
rake db:test:clone\_structure # Recreate the test databases  
from the development structure
