TDD for resources

Although this test might it doesn't actually check that a resource was created (since the implementation doesn't actually save anything). I would also check that the page you're redirected to contains some additional info:

```ruby
expect(page).to have_link("Descriptive Title", href: "http://www.google.com")
```

You can also check that the number of records in the database has changed:

```ruby
expect(Resource.count).to eq(1)
```
