Overview

Checks for the use of test methods outside of a test class.

Test methods should be defined within a test class to ensure their execution.

NOTE: This cop assumes that classes whose superclass name includes the word "Test" are test classes, in order to prevent false positives.

Examples:


# bad
class FooTest < Minitest::Test
end
def test_method_should_be_inside_test_class
end

# good
class FooTest < Minitest::Test
  def test_method_should_be_inside_test_class
  end
end
