wrong number of arguments (1 for 2) (ArgumentError)

No backtrace is given!

Expected Behavior

Current Behavior

see Steps to Reproduce (for bugs)

Possible Solution

Followed the error to:

{ArgumentError} wrong number of arguments (1 for 2)
"C:/Ruby22/lib/ruby/gems/2.2.0/gems/aruba-0.14.0/lib/aruba/platforms/windows_environment_variables.rb:84:in delete'" "C:/Ruby22/lib/ruby/gems/2.2.0/gems/aruba-0.14.0/lib/aruba/api/deprecated.rb:406:inblock in restore_env'"
"C:/Ruby22/lib/ruby/gems/2.2.0/gems/aruba-0.14.0/lib/aruba/api/deprecated.rb:401:in each'" "C:/Ruby22/lib/ruby/gems/2.2.0/gems/aruba-0.14.0/lib/aruba/api/deprecated.rb:401:inrestore_env'"
"C:/Ruby22/lib/ruby/gems/2.2.0/gems/aruba-0.14.0/lib/aruba/cucumber/hooks.rb:19:in `After'"

and found that the delete method, which is inherited from UnixEnvironmentVariables, has an extra argument that its super.

Steps to Reproduce (for bugs)

irb(main):001:0> require 'aruba'
=> true
irb(main):003:0> env = Aruba::Platforms::WindowsEnvironmentVariables.new
=> ...
irb(main):004:0> env['foo']='bar'
=> "bar"
irb(main):005:0> env['foo']
=> "bar"
irb(main):006:0> env.delete 'foo'
ArgumentError: wrong number of arguments (1 for 2)
        from C:/Ruby22/lib/ruby/gems/2.2.0/gems/aruba-0.14.0/lib/aruba/platforms/windows_environment_variables.rb:84:in `delete'
        from (irb):6
        from C:/Ruby22/bin/irb:11:in `<main>'
