Hi Rajkumar,
You can duplicate your development database as testing database and
specify the same in database.yml test environment. By doing this you
will get the desired result without loosing data from development
database.

No you don't. The point of a test database is to have something that
your tests can run against without messing with your dev data.

Yes you do. Tests must start from a known state, or they will not be
reliable.

how to do this.

Don't. It's a terrible, horrible, dangerous idea. Don't even consider
it.

Best,

Rails makes the right things to do very easy, and if you stray outside
that, well you made a conscious decision to go that route, and bear the
consequences.

You *are* using automated testing aren't you?

You *are* keeping your tests up to date with the code and data changes
you make in your development database on an ongoing basis?

You really need to look into some automated testing tools available for
Rails to do this with any kind of replicability and efficiency.

If you absolutely, positively, against-all-reason-and-recommendation
have to use the same database for dev and test, I would still not do
exactly that.

I'd suggest you use sqlite for your development database, and copy your
development.sqlite3 file to test.sqlite3 before running your tests, each
and every time.

Take a look at some Rails testing resources - http://guides.rubyonrails.org/testing.html
- take a look at the fixtures part.

I can't think of a reason not to have a separate testing database or
to try and run tests on the dev db, unless you are trying to re-invent
the wheel and make your own test suite. I think quite a few of us have
had the experience of trying to build something, like unit tests, that
have in place several standard solutions already.
