If a test is launched via a Rake task, it is the user's responsibility to provide code coverage measurement.
It is supposed that you have a special Rake task that collects code coverage information via rcov.
- Open for editing your *.rake file, and add the following code:
require 'rcov/rcovtask' Rcov::RcovTask.new do |t| t.libs << "test" t.test_files = FileList ['test/**/*_test.rb'] t.verbose = true end
- Create run/debug configuration for the task 'rcov' and run it with coverage.
