Generate only tests from existing model / controllers

Question

I have a Rails3 app that is based on someone else\'s work. For some reason they decided not to supply the tests with the app, which I am finding frustrating.

What I

Answer 1

To only generate the associated test files for an existing Rails 3 app, I use "generate resource" but skip everything that I don't want:

rails g resource Post --skip --no-resource-route --no-migration --no-helper --no-assets

Other options can be found using rails generate resource --help

-s, [--skip]     # Skip files that already exist
--resource-route            # Indicates when to generate resource route
[--helper]                # Indicates when to generate helper
[--assets]                # Indicates when to generate assets
[--migration]            # Indicates when to generate migration

Why not use generate scaffold? Because it might generate views that I'm not using.
