Tests failed during Debian packaging

[balasankarc]

Hi,
I am packaging generator_spec for debian and have hit a problem. As a part of packaging, the tests are automatically run. But, I got one failure while running the tests

Failures:

1. GeneratorSpec::Matcher::File#matches? with no contains throws :failure if it doesnt exist
   Failure/Error: expect {
   expected :failure to be thrown, got nothing

   ./spec/generator_spec/matcher_spec.rb:71:in `block (4 levels) in module:Matcher'

Finished in 0.11725 seconds
31 examples, 1 failure

As I am a novice in Ruby programming, I don't know what to do. Can you help me fix this?

Hello @balasankarc.

Can you add some steps how to reproduce this?

Can you confirm this for latest git master revision also?

[simi]

@balasankarc any news on this?

I can reproduce it with the Debian gem2deb tool.

gem2deb generator_spec

gem2deb extract the gem. Running rake spec from inside the gem sources I can also reproduce.
Nowadays I get 6 errors.

rspec ./spec/generator_spec/matcher_spec.rb:83 # GeneratorSpec::Matcher::File#matches? with no contains throws :failure if it doesnt exist
rspec ./spec/generator_spec/matcher_spec.rb:129 # GeneratorSpec::Matcher::Migration#matches? with no contains throws :failure if it doesnt exist
rspec ./spec/generator_spec/matcher_spec.rb:226 # GeneratorSpec::Matcher::Directory#matches? with a directory name throws :failure if it doesnt exist
rspec ./spec/generator_spec/matcher_spec.rb:254 # GeneratorSpec::Matcher::Directory#matches? with a directory object throws :failure if it doesnt exist
rspec ./spec/generator_spec/matcher_spec.rb:272 # GeneratorSpec::Matcher::Directory#matches? #no_file doesnt throw if the file exist
rspec ./spec/generator_spec/matcher_spec.rb:306 # GeneratorSpec::Matcher::Root#matches? returns false on failures

From a debug session ./spec/generator_spec/matcher_spec.rb uses as testdir TMP_ROO, ie Dir.tmpdir which here ends up as /tmp.
Obviously the before(:each) examples fail to delete this directory as it misses the permissions (luckily).
I believe the tests fail here as I do not run them as root (ie /tmp is not deleted before each test).

A short test case is in an irb session:

require 'tmpdir'
puts Dir.tmpdir

here it outputs /tmp
