Redmine

Hello.
If your plugin’s directory is empty, these message has no problem.
If any plugin installed under plugin’s directory and this plugin has directory for its test, such as test/, test/test_helper.rb and so on, test will be executed.
I hope this will be of some help.

Thanks for the answer, but what i mean is that if i run the test directly with ruby i don't get any warning:

ruby plugins/polls/test/functional/index_controller_test.rb 

Run options: --seed 34964

Javier, thanks for your additional comment.
This is because the rake task "redmine:plugins:test” run test script via Rake::TestTask, and by default, the Rake::TestTask run ruby with “-w” option.
So, a lot of warning are shown.

Ref. https://github.com/ruby/rake/blob/master/lib/rake/testtask.rb

Here is a workaround to hide warning messages. (Related issue: https://github.com/hanami/utils/issues/123)

Edit lib/tasks/redmine.rake:

    namespace :test do
      desc 'Runs the plugins unit tests.'
      Rake::TestTask.new :units => "db:test:prepare" do |t|
        t.libs << "test" 
        t.warning = false   # here
        t.verbose = true
        t.pattern = "plugins/#{ENV['NAME'] || '*'}/test/unit/**/*_test.rb" 
      end

      desc 'Runs the plugins functional tests.'
      Rake::TestTask.new :functionals => "db:test:prepare" do |t|
        t.libs << "test" 
        t.warning = false   # here
        t.verbose = true
        t.pattern = "plugins/#{ENV['NAME'] || '*'}/test/functional/**/*_test.rb" 
      end

      desc 'Runs the plugins integration tests.'
      Rake::TestTask.new :integration => "db:test:prepare" do |t|
        t.libs << "test" 
        t.warning = false   # here
        t.verbose = true
        t.pattern = "plugins/#{ENV['NAME'] || '*'}/test/integration/**/*_test.rb" 
      end

      desc 'Runs the plugins ui tests.'
      Rake::TestTask.new :ui => "db:test:prepare" do |t|
        t.libs << "test" 
        t.warning = false   # here
        t.verbose = true
        t.pattern = "plugins/#{ENV['NAME'] || '*'}/test/ui/**/*_test.rb" 
      end
    end

Also, change "t.verbose = true" to "t.verbose = false” will be hide verbose messages.

Great answer Akiko, thanks.
