Method has too many lines. [18/10]
Open

  def self.included(base)
    base.class_eval do
      context "A #{@base_class}" do
        setup do
          @related_item = Module.class_eval(@base_class).create! @new_model

This cop checks if the length of a method exceeds some maximum value. Comment lines can optionally be ignored. The maximum allowed length is configurable.

Assignment Branch Condition size for included is too high. [16.79/15]
Open

  def self.included(base)
    base.class_eval do
      context "A #{@base_class}" do
        setup do
          @related_item = Module.class_eval(@base_class).create! @new_model

This cop checks that the ABC size of methods is not higher than the configured maximum. The ABC size is based on assignments, branches (method calls), and conditions. See http://c2.com/cgi/wiki?AbcMetric

Use the return of the conditional for variable assignment and comparison.
Open

          unless @base_class == 'Topic'
            relations = @topic_related_to.send(@base_class.tableize)
          else
            relations = @topic_related_to.related_topics
          end

Do not use unless with else. Rewrite these with the positive case first.
Open

          unless @base_class == 'Topic'
            relations = @topic_related_to.send(@base_class.tableize)
          else
            relations = @topic_related_to.related_topics
          end

This cop looks for unless expressions with else clauses.

Example:

# bad
unless foo_bar.nil?
  # do something...
else
  # do a different thing...
end

# good
if foo_bar.present?
  # do something...
else
  # do a different thing...
end

Redundant curly braces around a hash parameter.
Open

          @topic_related_to = Basket.find(1).topics.create!({ title: 'The topic that the item is related to', topic_type_id: 1 })

This cop checks for braces around the last parameter in a method call if the last parameter is a hash. It supports braces, no_braces and context_dependent styles.

Example: EnforcedStyle: braces

# The `braces` style enforces braces around all method
# parameters that are hashes.

# bad
some_method(x, y, a: 1, b: 2)

# good
some_method(x, y, {a: 1, b: 2})

Example: EnforcedStyle: no_braces (default)

# The `no_braces` style checks that the last parameter doesn't
# have braces around it.

# bad
some_method(x, y, {a: 1, b: 2})

# good
some_method(x, y, a: 1, b: 2)

Example: EnforcedStyle: context_dependent

# The `context_dependent` style checks that the last parameter
# doesn't have braces around it, but requires braces if the
# second to last parameter is also a hash literal.

# bad
some_method(x, y, {a: 1, b: 2})
some_method(x, y, {a: 1, b: 2}, a: 1, b: 2)

# good
some_method(x, y, a: 1, b: 2)
some_method(x, y, {a: 1, b: 2}, {a: 1, b: 2})
