Creates a new example group. The what argument is a description from the user. The parent should contain this group. After creating this group, the parent's children should be updated. The parent's children must contain this group, otherwise there may be unexpected behavior. The hooks are stored to be triggered later.

Group that this is nested in.

Runs all of the post-condition checks. This method should run following every example in the group. Parent post-conditions will be checked last.

Runs all of the pre-condition checks. This method should run prior to every example in the group. Parent pre-conditions will be checked first.

Indicates wheter the group references a type.

Creates a string representation of the group. The string consists of #what appended to the parent. This results in a string like:

Foo#bar does something

for the following structure:

describe Foo do
  describe "#bar" do
    it "does something" do
      # ...
    end
  end
end

Description from the user of the group's contents. This is a symbol when referencing a type.

Creates a proc that runs the "around-each" hooks in addition to a block passed to this method. To call the block and all around_each hooks, just invoke Proc#call on the returned proc. Parent "around-each" hooks will be in the outermost wrappings.
