rake test and guard show different coverage reports for the same test suite

[csommerauer]

Ruby 1.9.2-p180, Rails 3.0.10, Test::Unit 2.4.5

guard-test (0.4.3)
guard (1.0.0)
simplecov (0.6.1)
simplecov-html (~> 0.5.3)

when running

bundle exec guard

the resulting coverage report is much lower than when running exactly the same test suite with

bundle exec rake:test

which seem to create the right coverage report .

When looking at the coverage within a file (i.e a model class), the only lines highlighted green are the lines with the def keyword and the method calls from within the class (i.e scope, validates, belongs_to and so on).
None of my code is highlight green as tested even though it is highlighted green when running the tests with rake

Please try setting a higher merge_timeout, i.e. SimpleCov.merge_timeout 3600. Check out the README for further info on this.

Also, people using guard & spork had a problem which was resolved with some configuration magic, but since you're using test/unit I assume it won't help you much. I'd still like to at least have it mentioned here - #42

Closing for now, if the problem persists please reopen the issue! And please also report back if and what fixed your problem so future visitors know it helped :)

Setting a higher merge_timeout did not work.

As I can get the coverage using rake, I don't consider this to be a major issue for me. I'll report back if I find a solution

Cool, thanks!

Is there a solution for the coverage problem today? I just ran into this issue quite a few times, but didn't find any working solution.

@csommerauer Did you ever find a solution for this?

[csommerauer]

@CharlesP unfortunately not. Sorry

[CharlesP]

@csommerauer That's a bummer...

@colszowka Can we reopen this issue?
