Create a controller without tests.

rails generate controller {controller name} {views/methods} --no-test-framework

Create integration test

rails generate integration_test {test_name}

Roll back a migration 

rake db:rollback

Rspec test for Mass Assign Vulnerbility (or attribute not being accessible):

describe "accessible attributes" do
  it "should not allow access to **Attribute**" do
    expect do
    **Model**.new(**Attribute**: **attr value**)
    end.to raise_error(ActiveModel::MassAssignmentSecurity::Error)
  end
end

Adding this too an rspec with capybara installed will open the page in your browser. Allows for easy debugging of failing tests.
