Call the run method on the benchmarker object and pass it two arguments. The first argument should be a string of the description. The second argument can be a block with any code you choose.
class SimpleBenchmarker
def run(description, &block)
start_time = Time.now
block.call
end_time = Time.now
elapsed = end_time - start_time
puts "\n#{description} results"
puts "Elapsed time: #{elapsed} seconds"
end
end
benchmarker = SimpleBenchmarker.new
def run(description, &block)
benchmarker.run "sleep a random amount of time" do
5.times do
print"."
sleep(rand(0.1..1.0))
end
end
my error is
The run method was not called. [:methods_called, :methods_called]
class SimpleBenchmarker
def run(description, &block)
start_time = Time.now
block.call
end_time = Time.now
elapsed = end_time - start_time
puts "\n#{description} results"
puts "Elapsed time: #{elapsed} seconds"
end
end
benchmarker = SimpleBenchmarker.new
def run(description, &block)
benchmarker.run "whatever", do
end
end

Look almost perfect, you should remove definition run method with end in the middle. Also, remove coma after description "whatever".
The reason is that we use run method to call benchmarker object in line 3, we don't have to create new another run method in definition in line 2.
For example:
benchmarker = SimpleBenchmarker.new
def run(description, &block)
benchmarker.run "whatever", do
end
end
;)
