# Important note: These tests are very expensive, and details of

|
# Django's database transaction model mean it does not super work to
|
|
# have a lot of migrations tested in this file at once; so we usually
|

# delete the old migration tests when adding a new one, so this file
|
|
# always has a single migration test in it as an example.
