Can't Run UnitTests: no such file to load -- test_helper

[dario_argento87]

I just installed RadRails. I am using Rails 2.0.1. When I try to run any rails unit tests. I get the following:

c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- test_helper (LoadError)
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
from ./test\unit\album_test.rb:1
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require'
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
from C:/workspace/.metadata/.plugins/org.rubypeople.rdt.testunit/RemoteTestRunner.rb:294

The test runs fine with rake. Here is the code for the test:

require 'test_helper'

class ReviewDetailTest < ActiveSupport::TestCase
# Replace this with your real tests.
def test_truth
assert true
end
end

Any ideas? I have used Rad Rails in the past and never experienced this.

How are you invoking the test? If you run all unit tests from the toolbar pulldown item, does that work? Does it work in rake and RadRails if you change the "require 'test_helper'" line to "require 'test/test_helper'" at top?

[dario_argento87]

It only runs successfully if I run it using rake. The problem is most likely with the require statement:
require 'test_helper'

I am at work now and I looked at some older code that was using Rails 1.2.6 and the require statement in the unit tests looks like this:
require File.dirname(__FILE__) + '/../test_helper'

It seems like the newer version of rails that I have installed at home, I think its 2.0.1, creates the test case a little differently. I am 99% positive that if I change the require statement to the above it will work. I'll check when I get home

I just downloaded Aptana, and was able to pull down my current rails project fine. However running any tests from within Aptana produces this:

Code: Select all

./test/unit/abstract_question_test.rb:1:in `require': no such file to load -- test_helper (LoadError)
   from ./test/unit/abstract_question_test.rb:1
   from /Users/stu/Documents/Aptana/.metadata/.plugins/org.radrails.rails.core/run_unit.rb:2:in `load'
   from /Users/stu/Documents/Aptana/.metadata/.plugins/org.radrails.rails.core/run_unit.rb:2
   from /Users/stu/Documents/Aptana/.metadata/.plugins/org.radrails.rails.core/run_unit.rb:2:in `each'
   from /Users/stu/Documents/Aptana/.metadata/.plugins/org.radrails.rails.core/run_unit.rb:2
   from /Users/stu/Documents/Aptana/.metadata/.plugins/org.rubypeople.rdt.testunit/RemoteTestRunner.rb:294:in `require'
   from /Users/stu/Documents/Aptana/.metadata/.plugins/org.rubypeople.rdt.testunit/RemoteTestRunner.rb:294

This happens when I invoke it every way I can find, including "Run As" ::Test. It also happens when I "Run Unit Tests" from the toolbar dropdown.

Tests run fine from Rake and also from within Netbeans.

It looks as though whatever kicks off the test in radrails isn't initializing the load path correctly.

I just read through http://forums.aptana.com/viewtopic.php? ... testhelper

...hopefully that isn't the final answer. I think tests should run as-is within the ide, and not require users to hard code a reference to libraries outside of /app or /lib (test_helper for instance, or other helpers in /test)

Netbeans had the same issue incidently. See http://www.netbeans.org/issues/show_bug.cgi?id=136650 . It's now fixed in their nightly (though the issue remains when launching under the debugger)

Aptana looks extremely promising. Nice work. Very cool how you're able to leverage the standard eclipse infrastructure in another language.

Hmm, I thought this wasn't broken when you ran all unit tests from the toolbar pulldown. In any case can you open a ticket for whatever cases this doesn't work (like launching individual tests)? http://support.aptana.com/asap

> require File.dirname(__FILE__) + '/../test_helper'

This worked for me. Thanks!

It's not clear to me if issue #ROR-886 is considered resolved because it has been fixed, considered resolved because it is a duplicate (of #ROR-893) or considered outstanding.

My experience shows that it is still outstanding. I have noted this failure in Edge Rails running with the latest Aptana code which my installation downloaded today.

What's the status? And what's the prognosis?

Any workaround OTHER than modifying every test to change the relative load path for test_helper.rb?

This is a big bummer...

I posted a workaround here:

[cwilliams]

It's considered closed because it's a duplicate of ROR-893. But ROR-893 is supposed to be fixed. Are you not seeing this? What version are you on? If you're using 1.0.3 or nightly builds, then please re-open the ticket...

[jemminger]

still broken in 1.0.3 for me: ROR-935 (cloned ROR-893 since I couldn't reopen it)
