It returns the first text child of the given node:

"  text( path = nil ) 

   A convenience method which returns the String value of the first child
   text element, if one exists, and nil otherwise.
   
   Note that an element may have multiple Text elements, perhaps
   separated by other children. Be aware that this method only returns
   the first Text node."

They are children of the node, but you have explicitly called
Element#elements which filters out the non-text children:

[documentation for REXML::Elements]

   each( xpath=nil, &block) {|e if e.kind_of? Element }| ...} 
   
   Iterates through all of the child Elements, optionally filtering them
   by a given XPath
   xpath: optional. If supplied, this is a String XPath, and is used to
   filter the children, so that only matching children are yielded. Note
   that XPaths are automatically filtered for Elements, so that
   non-Element children will not be yielded

...and text children are REXML::Text, not REXML::Element, so are skipped.

However you can use Element#each to iterate over all the children, both Text
and Element:

require "rexml/document"
include REXML

file=File.new("test2.xml")
doc=Document.new file

doc.each do |element|
  element.each do |child|
    if child.is_a?(REXML::Text)
      puts "Text: #{child.to_s.inspect}"
    else
      puts "SubElement: #{child.name}"
    end
  end
end
