instance method `assert_migration`

Ruby on Rails 3.0.20

Since v3.0.20 Last seen in v3.2.22.5

Compare with:

assert_migration(relative, *contents, &block)

Asserts a given file does not exist. You need to supply an absolute path or a path relative to the configured destination:

assert_migration "db/migrate/create_products.rb"

This method manipulates the given path and tries to find any migration which matches the migration name. For example, the call above is converted to:

assert_file "db/migrate/003_create_products.rb"

Consequently, assert_migration accepts the same arguments has assert_file.

Parameters

relative req
contents rest
block block
