| 65 | A processing class used to extract the <tt class="class">DocTest</tt>s that are |
| 66 | relevant to a given object, from its docstring and the docstrings |
| 67 | of its contained objects. <tt class="class">DocTest</tt>s can currently be |
| 68 | extracted from the following object types: modules, functions, |
| 69 | classes, methods, staticmethods, classmethods, and properties. |
| 70 | |
| 71 | <P> |
| 72 | The optional argument <var>verbose</var> can be used to display the |
| 73 | objects searched by the finder. It defaults to <code>False</code> (no |
| 74 | output). |
| 75 | |
| 76 | <P> |
| 77 | The optional argument <var>parser</var> specifies the |
| 78 | <tt class="class">DocTestParser</tt> object (or a drop-in replacement) that is |
| 79 | used to extract doctests from docstrings. |
| 80 | |
| 81 | <P> |
| 82 | If the optional argument <var>recurse</var> is false, then |
| 83 | <tt class="method">DocTestFinder.find()</tt> will only examine the given object, |
| 84 | and not any contained objects. |
| 85 | |
| 86 | <P> |
| 87 | If the optional argument <var>exclude_empty</var> is false, then |
| 88 | <tt class="method">DocTestFinder.find()</tt> will include tests for objects with |
| 89 | empty docstrings. |

| 106 | Return a list of the <tt class="class">DocTest</tt>s that are defined by |
| 107 | <var>obj</var>'s docstring, or by any of its contained objects' |
| 108 | docstrings. |
| 109 | |
| 110 | <P> |
| 111 | The optional argument <var>name</var> specifies the object's name; this |
| 112 | name will be used to construct names for the returned |
| 113 | <tt class="class">DocTest</tt>s. If <var>name</var> is not specified, then |
| 114 | <code><var>obj</var>.__name__</code> is used. |
| 115 | |
| 116 | <P> |
| 117 | The optional parameter <var>module</var> is the module that contains |
| 118 | the given object. If the module is not specified or is None, then |
| 119 | the test finder will attempt to automatically determine the |
| 120 | correct module. The object's module is used: |
| 121 | |
| 122 | <P> |
| 123 | |
| 124 | <UL> |
| 125 | <LI>As a default namespace, if <var>globs</var> is not specified. |
| 126 | </LI> |
| 127 | <LI>To prevent the DocTestFinder from extracting DocTests |
| 128 | from objects that are imported from other modules. (Contained |
| 129 | objects with modules other than <var>module</var> are ignored.) |
| 130 | </LI> |
| 131 | <LI>To find the name of the file containing the object. |
| 132 | </LI> |
| 133 | <LI>To help find the line number of the object within its file. |
| 134 | |
| 135 | </LI> |
| 136 | </UL> |
| 137 | |
| 138 | <P> |
| 139 | If <var>module</var> is <code>False</code>, no attempt to find the module |
| 140 | will be made. This is obscure, of use mostly in testing doctest |
| 141 | itself: if <var>module</var> is <code>False</code>, or is <code>None</code> but |
| 142 | cannot be found automatically, then all objects are considered to |
| 143 | belong to the (non-existent) module, so all contained objects will |
| 144 | (recursively) be searched for doctests. |
| 145 | |
| 146 | <P> |
| 147 | The globals for each <tt class="class">DocTest</tt> is formed by combining |
| 148 | <var>globs</var> and <var>extraglobs</var> (bindings in <var>extraglobs</var> |
| 149 | override bindings in <var>globs</var>). A new shallow copy of the globals |
| 150 | dictionary is created for each <tt class="class">DocTest</tt>. If <var>globs</var> is |
| 151 | not specified, then it defaults to the module's <var>__dict__</var>, if |
| 152 | specified, or <code>{}</code> otherwise. If <var>extraglobs</var> is not |
| 153 | specified, then it defaults to <code>{}</code>. |
