rails lib/* path in rspecs

[Igor Yurchenko]

Hi, ppl...

I need help with setting up rails evironment for rspec. I've created some code on lib/backup/status.rb path and matched specs at spec/lib/backup/status_spec.rb.

The problem is the spec does not see Backup::Status constant defined at lib/backup/status.rb...


Row "RSpec.describe Backup::Status do end" in spec/lib/backup/status.rb causes error:
/home/space/devel/sole/sola/spec/lib/backup/status_spec.rb:4:in `<top (required)>': uninitialized constant Backup (NameError)

Thanks in advance...

RSpec does not do any constant autoloading so if you're getting and uninitialized constant error but the constant is defined in a file, it means that file hasn't been loaded yet.  The simple solution is to `require` the file.

HTH,

Myron

Thank you for answer. The adding "require 'backup/status'" causes error in lib/backup/status.rb:

20:14:54 - INFO - Running: spec/lib/backup/status_spec.rb
Coverage report generated for RSpec to /home/space/devel/sole/sola/coverage. 1 / 7 LOC (14.29%) covered.
/home/space/devel/sole/sola/lib/backup/status.rb:1:in `<top (required)>': uninitialized constant Backup (NameError)
        from /home/space/devel/sole/sola/spec/lib/backup/status_spec.rb:2:in `require'
        from /home/space/devel/sole/sola/spec/lib/backup/status_spec.rb:2:in `<top (required)>'

lib/backup/status.rb contains:

class Backup::Status
...
end

I have supposed gem rspec_rails is responsible for similar kind of problem. But...

I would be very gratefull for any ideas how to solve this problem...

In Ruby, if you have a class Foo::Bar definition, it will fail with an error like the one you received if Foo has not already been defined. That’s simply how Ruby works and has nothing to do with RSpec. The solution is to change your class definition to:

module Backup
  class Status
    # ...
  end
end

(Note: that could be class Backup if that’s what you intend it to be.)

Alternately, if you want to keep the class Backup::Status form, you’ll have to require another file that does define the bare Backup class or module. Typically this require would go at the top of your lib/backup/status.rb file.

HTH,
Myron
