assert_migration(relative, *contents, &block) public

Asserts a given migration exists. 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.
