SimpleCov is not picking up any coverage for our project

We did manage to get it to work after a few weeks experimentation, however it still does not integrate with the IDE (so you can see the coverage percent next to each file in your project).  If someone could tell us how to make the integration feature work, we'd be most grateful.

To make simplecov work, we had to create a .simplecov file in the root of our project that contained the following (note, nothing else was necessary, it just worked from here):

module SimpleCov::Configuration
  def clean_filters
    @filters = []
  end
end

SimpleCov.configure do
  clean_filters
  load_adapter 'test_frameworks'
  add_filter '/Ruby192/'

  # You can add_filter here to add anything else you don't want to cover
end

SimpleCov.at_exit do

  base_result = {}

  # This next bit is to show what files we have no coverage for.  Without these lines, uncovered files are not reported...
  Dir["#{SimpleCov.root}/**/*.rb"].each do |file|
    absolute = File::expand_path(file)

    next unless absolute.start_with?(SimpleCov.root)
    next if SimpleCov.result.original_result.has_key?(absolute)

    lines = File.readlines(absolute).size
    base_result[absolute] = [0]*lines
  end

  merged = SimpleCov.result.original_result.merge_resultset(base_result)
  result = SimpleCov::Result.new(merged)
  result.command_name = SimpleCov.result.command_name
  result.format!

  puts "covered_percent: #{result.covered_percent}"
  minimum_coverage = 80
  if result.covered_percent < minimum_coverage
    error_message = "Coverage too low: #{result.covered_percent.round(2)}%, should be #{minimum_coverage}%"
    puts "##teamcity[buildStatus status=\'FAILURE\' text=\'{build.status.text}; #{error_message}\']"
    raise error_message
  end
end

SimpleCov.start 'test_frameworks'
