filters

before/after/around hooks defined in the RSpec configuration block can
be filtered using metadata. Arbitrary metadata can be applied to an example
or example group, and used to make a hook only apply to examples with the
given metadata.

Scenarios
  1. filter `before(:each)` hooks using arbitrary metadata
  2. filter `after(:each)` hooks using arbitrary metadata
  3. filter around(:each) hooks using arbitrary metadata
  4. filter before(:all) hooks using arbitrary metadata
  5. filter after(:all) hooks using arbitrary metadata
filter `before(:each)` hooks using arbitrary metadata
Given
a file named "filter_before_each_hooks_spec.rb" with: 
RSpec.configure do |config|
  config.before(:each, :foo => :bar) { puts "In hook" }
end

describe "group 1" do
  it("example 1") { }
  it("example 2", :foo => :bar) { }
end

describe "group 2", :foo => :bar do
  it("example 1") { }
  it("example 2", :foo => :bar) { }
end
When
I run "rspec filter_before_each_hooks_spec.rb --format documentation"
Then
the output should contain: 
group 1
  example 1
In hook
  example 2

group 2
In hook
  example 1
In hook
  example 2
filter `after(:each)` hooks using arbitrary metadata
Given
a file named "filter_after_each_hooks_spec.rb" with: 
RSpec.configure do |config|
  config.after(:each, :foo => :bar) { puts "In hook" }
end

describe "group 1" do
  it("example 1") { }
  it("example 2", :foo => :bar) { }
end

describe "group 2", :foo => :bar do
  it("example 1") { }
  it("example 2", :foo => :bar) { }
end
When
I run "rspec filter_after_each_hooks_spec.rb --format documentation"
Then
the output should contain: 
group 1
  example 1
In hook
  example 2

group 2
In hook
  example 1
In hook
  example 2
filter around(:each) hooks using arbitrary metadata
Given
a file named "filter_around_each_hooks_spec.rb" with: 
RSpec.configure do |config|
  config.around(:each, :foo => :bar) do |example|
    puts "Start hook"
    example.run
    puts "End hook"
  end
end

describe "group 1" do
  it("example 1") { }
  it("example 2", :foo => :bar) { }
end

describe "group 2", :foo => :bar do
  it("example 1") { }
  it("example 2", :foo => :bar) { }
end
When
I run "rspec filter_around_each_hooks_spec.rb --format documentation"
Then
the output should contain: 
group 1
  example 1
Start hook
End hook
  example 2

group 2
Start hook
End hook
  example 1
Start hook
End hook
  example 2
filter before(:all) hooks using arbitrary metadata
Given
a file named "filter_before_all_hooks_spec.rb" with: 
RSpec.configure do |config|
  config.before(:all, :foo => :bar) { puts "In hook" }
end

describe "group 1" do
  it("example 1") { }
  it("example 2") { }
end

describe "group 2", :foo => :bar do
  it("example 1") { }
  it("example 2") { }
end

describe "group 3" do
  describe "subgroup 1", :foo => :bar do
    it("example 1") { }
  end
end
When
I run "rspec filter_before_all_hooks_spec.rb --format documentation"
Then
the output should contain: 
group 1
  example 1
  example 2

group 2
In hook
  example 1
  example 2

group 3
  subgroup 1
In hook
    example 1
filter after(:all) hooks using arbitrary metadata
Given
a file named "filter_after_all_hooks_spec.rb" with: 
RSpec.configure do |config|
  config.after(:all, :foo => :bar) { puts "In hook" }
end

describe "group 1" do
  it("example 1") { }
  it("example 2") { }
end

describe "group 2", :foo => :bar do
  it("example 1") { }
  it("example 2") { }
end

describe "group 3" do
  describe "subgroup 1", :foo => :bar do
    it("example 1") { }
  end
end
When
I run "rspec filter_after_all_hooks_spec.rb --format documentation"
Then
the output should contain: 
group 1
  example 1
  example 2

group 2
  example 1
  example 2
In hook

group 3
  subgroup 1
    example 1
In hook
