Running specs multiple times with different runner options in the same process

Use clear_examples command to clear all example groups between different
runs in the same process. It:

clears all example groups
restores inclusion and exclusion filters set by configuration
clears inclusion and exclusion filters set by previous spec run (via runner)
resets all time counters (start time, load time, duration, etc.)
resets different counts of examples (all examples, pending and failed)

require "spec_helper"

RSpec::Core::Runner.run([... some parameters ...])

RSpec.clear_examples

RSpec::Core::Runner.run([... different parameters ...])

Background

Given

a file named "spec/spec_helper.rb" with:

RSpec.configure do |config|
  config.filter_run_when_matching :focus => true
  config.filter_run_excluding :slow => true
end

Given

a file named "spec/truth_spec.rb" with:

require 'spec_helper'

RSpec.describe "truth" do
  describe true do
    it "is truthy" do
      expect(true).to be_truthy
    end

    it "is not falsy" do
      expect(true).not_to be_falsy
    end
  end

  describe false do
    it "is falsy" do
      expect(false).to be_falsy
    end

    it "is truthy" do
      expect(false).not_to be_truthy
    end
  end
end

Scenarios

Running specs multiple times in the same process

Given

a file named "scripts/multiple_runs.rb" with:

require 'rspec/core'

RSpec::Core::Runner.run(['spec'])
RSpec.clear_examples
RSpec::Core::Runner.run(['spec'])

When

I run ruby scripts/multiple_runs.rb

Then

the output should match:

4 examples, 0 failures
.*
4 examples, 0 failures

Running specs multiple times in the same process with different parameters

Given

a file named "spec/bar_spec.rb" with:

require 'spec_helper'

RSpec.describe 'bar' do
  subject(:bar) { :focused }

  it 'is focused', :focus do
    expect(bar).to be(:focused)
  end
end

Given

a file named "scripts/different_parameters.rb" with:

require 'rspec/core'

RSpec::Core::Runner.run(['spec'])
RSpec.clear_examples
RSpec::Core::Runner.run(['spec/truth_spec.rb:4'])
RSpec.clear_examples
RSpec::Core::Runner.run(['spec', '-e', 'fals'])

When

I run ruby scripts/different_parameters.rb

Then

the output should match:

1 example, 0 failures
.*
2 examples, 0 failures
.*
3 examples, 0 failures
