Using benchmark for wait times

I’m trying to use Benchmark, to return the wait time for a search in an
application, and thought I could fairly neatly wrap up the wait time
like this:

$logger.log(Benchmark.measure($ie.wait()))

However, when I run this test from my harness, I get the following in
the console:

LocalJumpError: no block given
C:/ruby/lib/ruby/1.8/benchmark.rb:293:in measure' ./Tests/test_audittrail.rb:119 ./Tests/test_audittrail.rb:61:ineach’
./Tests/test_audittrail.rb:61
C:/workspace/CV_Auto/harness.rb:41:in load' C:/workspace/CV_Auto/harness.rb:41:intest_audittrail’

What confuses me further is that line 61 reads:
message_type.each do |link|
$logger.log("")

which when I diff it against my last version, I can see has not changed.

What I’d like to know is:

Am I off the mark wrapping the wait in a measure and then logging it?

Why does my each statement now fail?

You are not “wrapping the wait in a measure”. Instead you invoke #wait
and stuff the result into #measure. Consider this:

$ ruby -r benchmark -e ‘puts Benchmark.measure( sleep(1) )’
/usr/lib/ruby/1.8/benchmark.rb:293:in `measure’: no block given
(LocalJumpError)
from -e:1

[email protected] ~
$ ruby -r benchmark -e ‘puts Benchmark.measure{ sleep(1) }’
0.000000 0.000000 0.000000 ( 1.000000)
