* Tests can be run in isolation
* Dependencies added
* A few tests modified to avoid depending on AS deps
not depended on my files they were testing

# This helper offers a method to measure the execution time of a block
|
|
# in a template.
|
|
module BenchmarkHelper
|
|
# Allows you to measure the execution time of a block
|
|
# in a template and records the result to the log. Wrap this block around
|
|
# expensive operations or possible bottlenecks to get a time reading
|
|
# for the operation. For example, let's say you thought your file
|
|
# processing method was taking too long; you could wrap it in a benchmark block.
|
|
#
|
|
# <% benchmark "Process data files" do %>
|
|
# <%= expensive_files_operation %>
|
|
# <% end %>
|
|
#
|
|
# That would add something like "Process data files (345.2ms)" to the log,
|
|
# which you can then use to compare timings when optimizing your code.
|
|
#
|
|
# You may give an optional logger level as the :level option.
|
|
# (:debug, :info, :warn, :error); the default value is :info.
|
|
#
|
|
# <% benchmark "Low-level files", :level => :debug do %>
|
|
# <%= lowlevel_files_operation %>
|
|
# <% end %>
|
|
#
|
|
# Finally, you can pass true as the third argument to silence all log activity
|
|
# inside the block. This is great for boiling down a noisy block to just a single statement:
|
|
#
|
|
# <% benchmark "Process data files", :level => :info, :silence => true do %>
|
|
# <%= expensive_and_chatty_files_operation %>
|
|
# <% end %>
