Rails aborted error message

I'm getting an error while running the following test $ rails test:models

Below is a sample of the error:

Run options: --seed 40805 Finished in 0.046173s, 21.6575 runs/s, 21.6575 assertions/s. rails aborted! ArgumentError: wrong number of arguments (given 1, expected 0) /usr/local/rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/test_unit/minitest_plugin.rb:9:in aggregated_results' /usr/local/rvm/gems/ruby-2.3.1/gems/minitest-5.10.2/lib/minitest.rb:597:inreport'

Any help would be greatly appreciated!
