NoMethodError: undefined method `call'

When running the following test suite:

require 'spec_helper'

describe User do
  before { @user = User.(name: "Example User", email: "user@example.com" }

  subject { @user }

  it { should respond_to(:name) }
  it { should respond_to(:email) }
end  

I get this error:

Failure/Error: before { @user = User.(name: "Example User", email: "user@example.com") }
NoMethodError:
  undefined method `call' for #<Class:0x007fdfd5dd8008>
  # ./spec/models/user_spec.rb:15:in `block (2 levels) in <top (required)>'

Creating the user works in the console just fine and it responds to the methods.
