Unable to run tests from sublime text 3

Question

I am trying to running a sample test suite from Sublime Text 3.

This is my example that I created using bundle gem foo -t minitest

class TestFoo < MiniTest::Unit::TestCase
  def test_that_it_has_a_version_number_test
    refute_nil ::Foo::VERSION
  end

  def test_it_does_something_useful_test
    assert true
  end
end

I have installed the RubyTest package, and the binding to run the test suite is Ctrl + Shift + T

I get the following error:

/home/thetuxracer/.rvm/rubies/ruby-2.0.0-p247/bin/ruby:1: Invalid char `\x7F' in expression
/home/thetuxracer/.rvm/rubies/ruby-2.0.0-p247/bin/ruby:1: Invalid char `\x02' in expression
/home/thetuxracer/.rvm/rubies/ruby-2.0.0-p247/bin/ruby:1: Invalid char `\x01' in expression
/home/thetuxracer/.rvm/rubies/ruby-2.0.0-p247/bin/ruby:1: Invalid char `\x01' in expression
/home/thetuxracer/.rvm/rubies/ruby-2.0.0-p247/bin/ruby:1:in `<main>': uninitialized constant ELF (NameError)
[Finished in 0.3s with exit code 1]

Observations:

I have installed ruby 2.0.0p247 using rvm. If I run the tests from the CLI, using

ruby -Itest foo_test.rb the tests run fine.

I also ensured that the key check_for_rvm in RubyTest.sublime-settings is set to true

What seems to be the problem here? Please let me know if there is anymore information that you may need to help me out.

EDIT: I tried this on a Mac Os X 10.8.4 with ST3 and ruby 2.0.0p247. In the Rakefile, I have also added this line t.test_files = FileList['test/test_*.rb'] in the RakeTask.

I looked at this bug and started ST from the shortcut. But the tests still didnt run.

Answer 1

I tried everything, from changing configurations in existing projects where the minitest runs, to re-installing the ST3 package to reinstalling ruby itself as a last resort. The problem, it turns out was way smaller.

When I execute this command bundle foo -t minitest the following files are created:

bundle gem foo -t minitest
      create  foo/Gemfile
      create  foo/Rakefile
      create  foo/LICENSE.txt
      create  foo/README.md
      create  foo/.gitignore
      create  foo/foo.gemspec
      create  foo/lib/foo.rb
      create  foo/lib/foo/version.rb
      create  foo/test/minitest_helper.rb
      create  **foo/test/test_foo.rb**
      create  foo/.travis.yml

Notice the name of the file containing test cases. I renamed it to foo_test and it just worked.

I now need to figure out, why minitest needs the filename in that particular format and if possible, change/edit it.

From looking at this issue, it's probably related to your bundler generated binstubs.

Looking at the RVM docs, you might want to try running:

gem regenerate_binstubs

or:

bundle install --binstubs

If you still have issues after that, I'd try totally removing the binstubs. Instructions for doing that can be found here.
