transactional examples

By default rspec executes each individual example in a transaction.

You can also explicitly enable/disable transactions the configuration
property 'usetransactionalexamples'.

Scenarios
run in transactions (default)
Given
a file named "spec/models/widget_spec.rb" with:
require "spec_helper"

describe Widget do
  it "has none to begin with" do
    Widget.count.should == 0
  end

  it "has one after adding one" do
    Widget.create
    Widget.count.should == 1
  end

  it "has none after one was created in a previous example" do
    Widget.count.should == 0
  end
end
When
I run rspec spec/models/widget_spec.rb
Then
the examples should all pass
run in transactions (explicit)
Given
a file named "spec/models/widget_spec.rb" with:
require "spec_helper"

RSpec.configure do |c|
  c.use_transactional_examples = true
end

describe Widget do
  it "has none to begin with" do
    Widget.count.should == 0
  end

  it "has one after adding one" do
    Widget.create
    Widget.count.should == 1
  end

  it "has none after one was created in a previous example" do
    Widget.count.should == 0
  end
end
When
I run rspec spec/models/widget_spec.rb
Then
the examples should all pass
disable transactions (explicit)
Given
a file named "spec/models/widget_spec.rb" with:
require "spec_helper"

RSpec.configure do |c|
  c.use_transactional_examples = false
end

describe Widget do
  it "has none to begin with" do
    Widget.count.should == 0
  end

  it "has one after adding one" do
    Widget.create
    Widget.count.should == 1
  end

  it "has one after one was created in a previous example" do
    Widget.count.should == 1
  end

  after(:all) { Widget.destroy_all }
end
When
I run rspec spec/models/widget_spec.rb
Then
the examples should all pass
run in transactions with fixture
Given
a file named "spec/models/thing_spec.rb" with:
require "spec_helper"

describe Thing do
  fixtures :things
  it "fixture method defined" do
    things(:one)
  end
end
Given
a file named "spec/fixtures/things.yml" with:
one:
  name: MyString
When
I run rspec spec/models/thing_spec.rb
Then
the examples should all pass
