Simplecov: No data is generated

[pupeno]

Hello,

I'm not sure when simplecov stopped generating data for my project, the html is generated but no file is mentioned. I'm configuring it this way:

# Setup simplecov.
require "simplecov"
SimpleCov.start "rails"
SimpleCov.command_name # Needed to separate test suits, due to issue https://github.com/colszowka/simplecov/issues/45

Setting config.cache_classes to false made it generate some data.

[pupeno]

If I start simplecov like this:

SimpleCov.start

without specifying "rails" I get code coverate but only for files in the test directory.

[jrmehle]

I am seeing the same issue, but with Rspec. Ruby 1.9.2 p290, Rails 3.1.

If I use SimpleCov.start in spec_helper.rb, it only shows my spec files in the coverage report (of course they are all 100%) and if I use SimpleCov.start 'rails', then it doesn't show any data at all.

[macedo]

I got the same issue too.

[aribeiro]

Hi guys, same issue here too.

[lucasallan]

I have the same issue too

[colszowka]

Hey guys. For some reason I'm not getting mails from github on new issues, sorry for being late :)

Actually SimpleCov.command_name will need an argument, like "Unit Tests". Could you please try to go with SimpleCov.command_name 'Unit Tests' and report back if that fixes the problem?

[macedo]

SimpleCov.command_name 'RSpec' not works for me =/

[lucasallan]

Didn't work for me either.

[lucasallan]

Hey guys

I changed the gem's declaration in my Gemfile and it works.
Before I have something like that:

gem 'simplecov', :require => false

Then I removed the 'require => false'

Now it works fine.

[yalab]

Hey guys.

I write setting first line on test/test_helper.rb
like this

require 'simplecov'
SimpleCov.start 'rails' do
  add_filter "/gems/"
end

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)

It work fine.

[jrmehle]

I did some more investigation and I still can't get simplecov to generate any report data other than on my spec files (which all report 100%).

I tried several permutations of requiring the gem in the Gemfile or in the spec_helper, Simplecov.start with and without 'rails', and also including or not including the command_line calls.

Still no luck. :(

[pupeno]

I was requiring simplecov after doing require File.expand_path('../../config/environment', FILE), now I put the require and start for simplecov on top, as instructed by the documentation (doh!) and it worked.

[jrmehle]

Ahh ha! Pupeno nailed the problem. You must place the require and start calls before File.expand_path... to get it to work. This could definitely be made more clear in the README as several of us have run into this gotcha.

[kippr]

Fix confirmed - same for me: moved the Simplecov.start above file expand and it alls works. Fab stuff!

[colszowka]

Guys, I'm glad you managed to figure this one out yourselves. I already went through various permutations of the README to make it superclear that the require should be happening before loading anything else, so obviously I didn't even consider mentioning this here as a possible source for the problem. Great that you've got it to work anyway :)

If you have suggestions on how to improve the README so that your past selfs would have realized this earlier please let me know :)

Also, if someone in here bumps into partially "vanishing" coverage (particularily using rspec) please check out #60. That one is a nasty motherfucker I'm telling you...

[kippr]

LOL - yeah, so that's pretty obvious. I read about simplecov elsewhere, and google brought me to this page, not the readme. At least it'll help future selfs figure out the problem quick, plus give them a chance to laugh at us doofuses! :)

[karishmamalkan]

im facing the same issue :( Does the test gemfile and application gemfile need to be the same.. my application has a separate gemfile so where do i start simplecov?

[jmervine]

I had this issue, not with rails, but with a gem I was developing and removing gemspec from my Gemfile fixed it.

[ghost]

I get this issue as well. I am using SimpleCov with RubyMine IDE.

and this what the coverage report looks like:

Really need some help

[harold-s]

If someone is not finding a solution. My problem in a Rails project was not having a .rspec file with inside
--color --require spec_helper
Guessed spec_helper was not called right a the beginning and so simplecov registered too late,
