[openstack-dev] [neutron] questions about uni test

[Gareth]

Hey neutron guys

What will happen if I remove this line[0]?

When running unit test, do we create tables in real database?

Creates and deletes actually.

Line 69 creates all the tables when a test starts.

Line 78 uses the unittest framework to add the function clear_tables() to the
post-test operations that are run after every test. So after a test finishes,
all the tables will be deleted by line 76.


Neutron's unit test framework uses a sqlite in-memory database, yes. This is
configured by [1].

That line has nothing to do with what database backend you use (SQLite
or mysql or whatever), it's used to clear the contents of the tables
so the next test starts with a clean DB.

It creates and cleans the tables in memory?
