exclusion filters

You can exclude examples from a run by declaring an exclusion filter and
then tagging examples, or entire groups, with that filter.

If you set the treat_symbols_as_metadata_keys_with_true_values config option
to true, you can specify metadata using only symbols.

Scenarios
  1. exclude an example
  2. exclude a group
  3. exclude multiple groups
  4. before/after(:all) hooks in excluded example group are not run
  5. Use symbols as metadata
exclude an example
Given
a file named "spec/sample_spec.rb" with: 
RSpec.configure do |c|
  # declare an exclusion filter
  c.filter_run_excluding :broken => true
end

describe "something" do
  it "does one thing" do
  end

  # tag example for exclusion by adding metadata
  it "does another thing", :broken => true do
  end
end
When
I run rspec ./spec/sample_spec.rb --format doc
Then
the output should contain "does one thing"
And
the output should not contain "does another thing"
exclude a group
Given
a file named "spec/sample_spec.rb" with: 
RSpec.configure do |c|
  c.filter_run_excluding :broken => true
end

describe "group 1", :broken => true do
  it "group 1 example 1" do
  end

  it "group 1 example 2" do
  end
end

describe "group 2" do
  it "group 2 example 1" do
  end
end
When
I run rspec ./spec/sample_spec.rb --format doc
Then
the output should contain "group 2 example 1"
And
the output should not contain "group 1 example 1"
And
the output should not contain "group 1 example 2"
exclude multiple groups
Given
a file named "spec/sample_spec.rb" with: 
RSpec.configure do |c|
  c.filter_run_excluding :broken => true
end

describe "group 1", :broken => true do
  before(:all) do
    raise "you should not see me"
  end
  
  it "group 1 example 1" do
  end

  it "group 1 example 2" do
  end
end

describe "group 2", :broken => true do
  before(:each) do
    raise "you should not see me"
  end
  
  it "group 2 example 1" do
  end
end
When
I run rspec ./spec/sample_spec.rb --format doc
Then
the output should match /All examples were filtered out/
And
the examples should all pass
And
the output should not contain "group 1"
And
the output should not contain "group 2"
before/after(:all) hooks in excluded example group are not run
Given
a file named "spec/before_after_all_exclusion_filter_spec.rb" with: 
RSpec.configure do |c|
  c.filter_run_excluding :broken => true
end

describe "group 1" do
  before(:all) { puts "before all in included group" }
  after(:all)  { puts "after all in included group"  }

  it "group 1 example" do
  end
end

describe "group 2", :broken => true do
  before(:all) { puts "before all in excluded group" }
  after(:all)  { puts "after all in excluded group"  }

  context "context 1" do
    it "group 2 context 1 example 1" do
    end
  end
end
When
I run rspec ./spec/before_after_all_exclusion_filter_spec.rb
Then
the output should contain "before all in included group"
And
the output should contain "after all in included group"
And
the output should not contain "before all in excluded group"
And
the output should not contain "after all in excluded group"
Use symbols as metadata
Given
a file named "symbols_as_metadata_spec.rb" with: 
RSpec.configure do |c|
  c.treat_symbols_as_metadata_keys_with_true_values = true
  c.filter_run_excluding :broken
end

describe "something" do
  it "does one thing" do
  end

  # tag example for exclusion by adding metadata
  it "does another thing", :broken do
  end
end
When
I run rspec symbols_as_metadata_spec.rb --format doc
Then
the output should contain "does one thing"
And
the output should not contain "does another thing"
