<dd>
A processing class used to extract the <tt class="class">DocTest</tt>s that are
relevant to a given object, from its docstring and the docstrings
of its contained objects. <tt class="class">DocTest</tt>s can currently be
extracted from the following object types: modules, functions,
classes, methods, staticmethods, classmethods, and properties.
<P>
The optional argument <var>verbose</var> can be used to display the
objects searched by the finder. It defaults to <code>False</code> (no
output).
<P>
The optional argument <var>parser</var> specifies the
<tt class="class">DocTestParser</tt> object (or a drop-in replacement) that is
used to extract doctests from docstrings.
<P>
If the optional argument <var>recurse</var> is false, then
<tt class="method">DocTestFinder.find()</tt> will only examine the given object,
and not any contained objects.
<P>
If the optional argument <var>exclude_empty</var> is false, then
<tt class="method">DocTestFinder.find()</tt> will include tests for objects with
empty docstrings.
<P>
<span class="versionnote">New in version 2.4.</span>
</dl>
<P>
<tt class="class">DocTestFinder</tt> defines the following method:
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
<td><nobr><b><tt id='l2h-1095' xml:id='l2h-1095' class="method">find</tt></b>(</nobr></td>

module</var><big>]</big><var></var><big>[</big><var>, globs</var><big>]</big><var></var><big>[</big><var>, extraglobs</var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
Return a list of the <tt class="class">DocTest</tt>s that are defined by
<var>obj</var>'s docstring, or by any of its contained objects'
docstrings.
<P>
The optional argument <var>name</var> specifies the object's name; this
name will be used to construct names for the returned
<tt class="class">DocTest</tt>s. If <var>name</var> is not specified, then
<code><var>obj</var>.__name__</code> is used.
<P>
The optional parameter <var>module</var> is the module that contains
the given object. If the module is not specified or is None, then
the test finder will attempt to automatically determine the
correct module. The object's module is used:
<P>
<UL>
<LI>As a default namespace, if <var>globs</var> is not specified.
</LI>
<LI>To prevent the DocTestFinder from extracting DocTests
from objects that are imported from other modules. (Contained
objects with modules other than <var>module</var> are ignored.)
</LI>
<LI>To find the name of the file containing the object.
</LI>
<LI>To help find the line number of the object within its file.
</LI>
</UL>
<P>
If <var>module</var> is <code>False</code>, no attempt to find the module
will be made. This is obscure, of use mostly in testing doctest
itself: if <var>module</var> is <code>False</code>, or is <code>None</code> but
cannot be found automatically, then all objects are considered to
belong to the (non-existent) module, so all contained objects will
(recursively) be searched for doctests.
<P>
The globals for each <tt class="class">DocTest</tt> is formed by combining
<var>globs</var> and <var>extraglobs</var> (bindings in <var>extraglobs</var>
override bindings in <var>globs</var>). A new shallow copy of the globals
dictionary is created for each <tt class="class">DocTest</tt>. If <var>globs</var> is
not specified, then it defaults to the module's <var>__dict__</var>, if
specified, or <code>{}</code> otherwise. If <var>extraglobs</var> is not
specified, then it defaults to <code>{}</code>.
