# 1) Use VCR.use_cassette in your let block. This will use
# the cassette just for requests made by creating bar, not
# for anything else in your test.
let(:foo) { VCR.use_cassette("foo") { create(:bar) } }
it "uses foo" do
  foo

# 2) Wrap the it block that uses #foo in VCR.use_cassette.

Abstract

You could have postgre installed on localhost with password (or without user or password seted after instalation) but if we are developing we really don't need password, so configuring postgre server without password for all your rails project is usefull.

Install Postgre packages

• postgresql
• postgresql-client
• libpq-dev
