Hi,

I’ve a Rakefile generated by jeweler. It uses rcov default but that
doesn’t properly work with 1.9 (I’m using 1.9.2), so I’d like to enable
simplecov for my tests. I’ve used simplecov successfully without a
Rakefile.

I added

gem “simplecov”, “>= 0.4.0”

to Gemfile and modified the test task:

require ‘rake/testtask’
require ‘simplecov’
Rake::TestTask.new(:test) do |test|
SimpleCov.start do
add_filter ‘test_’
end
test.libs << ‘lib’ << ‘test’
test.pattern = ‘test/**/test_*.rb’
test.verbose = true
end

simplecov is executed, but doesn’t record anything:

Coverage report generated for rake to coverage. 0 / 0 LOC (0.0%)
covered.

As far as I can see, simplecov doesn’t provide a ready rake task, how
can I use it in this case? I’ve gone through the rake documentation but
didn’t spot anything obvious I’m missing.

thanks,

  • Markus

I’m not super familiar with simplecov, but i just merged a patch that
implements it on one of my projects this morning:

Hope that helps you? It runs the coverage report on every task, though.

Thanks, that helped at least get some result. However the coverage
itself is wrong, it’s not 12.8% (80/625 LOC), when the real coverage
(standalone without rake) is 597 / 626 LOC (95.37%).

Without the Rakefile, all I do is

$ cat mylib_simplecov.rb
require ‘simplecov’
SimpleCov.start do
add_filter ‘_test’
end
require_relative ‘mylib_test’

and mylib_test starts with

$ head mylib_test.rb
require ‘test/unit’
require_relative ‘mylib’

module MylibTests
class Misc < Test::Unit::TestCase

and that’s all and it works.

I thought moving to jeweler and all the other stuff makes things easier,
but currently it made it just harder :confused:
