msgid "How It Works"
msgstr ""

msgid ""
"This section examines in detail how doctest works: which docstrings it looks "
"at, how it finds interactive examples, what execution context it uses, how "
"it handles exceptions, and how option flags can be used to control its "
"behavior. This is the information that you need to know to write doctest "
"examples; for information about actually running doctest on these examples, "
"see the following sections."
msgstr ""

msgid "Which Docstrings Are Examined?"
msgstr ""

msgid ""
"The module docstring, and all function, class and method docstrings are "
"searched.  Objects imported into the module are not searched."
msgstr ""

msgid ""
"In addition, there are cases when you want tests to be part of a module but "
"not part of the help text, which requires that the tests not be included in "
"the docstring. Doctest looks for a module-level variable called ``__test__`` "
"and uses it to locate other tests. If ``M.__test__`` exists, it must be a "
"dict, and each entry maps a (string) name to a function object, class "
"object, or string. Function and class object docstrings found from ``M."
"__test__`` are searched, and strings are treated as if they were "
"docstrings.  In output, a key ``K`` in ``M.__test__`` appears with name ``M."
"__test__.K``."
msgstr ""

msgid "For example, place this block of code at the top of :file:`example.py`:"
msgstr ""

msgid ""
"__test__ = {\n"
"    'numbers': \"\"\"\n"
">>> factorial(6)\n"
"720\n"
"\n"
">>> [factorial(n) for n in range(6)]\n"
"[1, 1, 2, 6, 24, 120]\n"
"\"\"\"\n"
"}"
msgstr ""

msgid ""
"The value of ``example.__test__[\"numbers\"]`` will be treated as a "
"docstring and all the tests inside it will be run. It is important to note "
"that the value can be mapped to a function, class object, or module; if so, :"
"mod:`!doctest` searches them recursively for docstrings, which are then "
"scanned for tests."
msgstr ""

msgid ""
"Any classes found are recursively searched similarly, to test docstrings in "
"their contained methods and nested classes."
msgstr ""

msgid "How are Docstring Examples Recognized?"
msgstr ""

msgid ""
"In most cases a copy-and-paste of an interactive console session works fine, "
"but doctest isn't trying to do an exact emulation of any specific Python "
"shell."
msgstr ""

msgid ""
">>> # comments are ignored\n"
">>> x = 12\n"
">>> x\n"
"12\n"
">>> if x == 13:\n"
"...     print(\"yes\")\n"
"... else:\n"
"...     print(\"no\")\n"

"...     print(\"NO!!!\")\n"
"...\n"
"no\n"
"NO\n"
"NO!!!\n"
">>>"
msgstr ""

msgid ""
"Any expected output must immediately follow the final ``'>>> '`` or ``'... "
"'`` line containing the code, and the expected output (if any) extends to "
"the next ``'>>> '`` or all-whitespace line."
msgstr ""

msgid "The fine print:"
msgstr ""

msgid ""
"Expected output cannot contain an all-whitespace line, since such a line is "
"taken to signal the end of expected output.  If expected output does contain "
"a blank line, put ``<BLANKLINE>`` in your doctest example each place a blank "
"line is expected."
msgstr ""

msgid ""
"All hard tab characters are expanded to spaces, using 8-column tab stops. "
"Tabs in output generated by the tested code are not modified.  Because any "
"hard tabs in the sample output *are* expanded, this means that if the code "
"output includes hard tabs, the only way the doctest can pass is if the :"
"const:`NORMALIZE_WHITESPACE` option or :ref:`directive <doctest-directives>` "
"is in effect. Alternatively, the test can be rewritten to capture the output "
"and compare it to an expected value as part of the test.  This handling of "
"tabs in the source was arrived at through trial and error, and has proven to "
"be the least error prone way of handling them.  It is possible to use a "
"different algorithm for handling tabs by writing a custom :class:"
"`DocTestParser` class."
msgstr ""

msgid ""
"Output to stdout is captured, but not output to stderr (exception tracebacks "
"are captured via a different means)."
msgstr ""

msgid ""
"If you continue a line via backslashing in an interactive session, or for "
"any other reason use a backslash, you should use a raw docstring, which will "
"preserve your backslashes exactly as you type them::"
msgstr ""

msgid ""
">>> def f(x):\n"
"...     r'''Backslashes in a raw docstring: m\\n'''\n"
"...\n"
">>> print(f.__doc__)\n"
"Backslashes in a raw docstring: m\\n"
msgstr ""

msgid ""
"Otherwise, the backslash will be interpreted as part of the string. For "
"example, the ``\\n`` above would be interpreted as a newline character.  "
"Alternatively, you can double each backslash in the doctest version (and not "
"use a raw string)::"
msgstr ""

msgid ""
">>> def f(x):\n"
"...     '''Backslashes in a raw docstring: m\\\\n'''\n"
"...\n"
">>> print(f.__doc__)\n"
"Backslashes in a raw docstring: m\\n"
msgstr ""

msgid "The starting column doesn't matter::"
msgstr ""

msgid ""
">>> assert \"Easy!\"\n"
"      >>> import math\n"
"          >>> math.floor(1.9)\n"
"          1"
msgstr ""
">>> assert \"Easy!\"\n"
"      >>> import math\n"
"          >>> math.floor(1.9)\n"
"          1"

msgid ""
"and as many leading whitespace characters are stripped from the expected "
"output as appeared in the initial ``'>>> '`` line that started the example."
msgstr ""

msgid "What's the Execution Context?"
msgstr ""

msgid ""
"By default, each time :mod:`doctest` finds a docstring to test, it uses a "
"*shallow copy* of :mod:`!M`'s globals, so that running tests doesn't change "
"the module's real globals, and so that one test in :mod:`!M` can't leave "
"behind crumbs that accidentally allow another test to work.  This means "
"examples can freely use any names defined at top-level in :mod:`!M`, and "
"names defined earlier in the docstring being run. Examples cannot see names "
"defined in other docstrings."
msgstr ""

msgid ""
"You can force use of your own dict as the execution context by passing "
"``globs=your_dict`` to :func:`testmod` or :func:`testfile` instead."
msgstr ""

msgid "What About Exceptions?"
msgstr ""

msgid ""
"No problem, provided that the traceback is the only output produced by the "
"example:  just paste in the traceback. [#]_ Since tracebacks contain details "
"that are likely to change rapidly (for example, exact file paths and line "
"numbers), this is one case where doctest works hard to be flexible in what "
"it accepts."
msgstr ""

msgid "Simple example::"
msgstr ""

msgid ""
">>> [1, 2, 3].remove(42)\n"
"Traceback (most recent call last):\n"
"  File \"<stdin>\", line 1, in <module>\n"
"ValueError: list.remove(x): x not in list"
msgstr ""

msgid ""
"That doctest succeeds if :exc:`ValueError` is raised, with the ``list."
"remove(x): x not in list`` detail as shown."
msgstr ""

msgid ""
"The expected output for an exception must start with a traceback header, "
"which may be either of the following two lines, indented the same as the "
"first line of the example::"
msgstr ""

msgid ""
"Traceback (most recent call last):\n"
"Traceback (innermost last):"
msgstr ""

msgid ""
"The traceback header is followed by an optional traceback stack, whose "
"contents are ignored by doctest.  The traceback stack is typically omitted, "
"or copied verbatim from an interactive session."
msgstr ""

msgid ""
"The traceback stack is followed by the most interesting part: the line(s) "
"containing the exception type and detail.  This is usually the last line of "
"a traceback, but can extend across multiple lines if the exception has a "
"multi-line detail::"
msgstr ""

msgid ""
">>> raise ValueError('multi\\n    line\\ndetail')\n"
"Traceback (most recent call last):\n"
"  File \"<stdin>\", line 1, in <module>\n"
"ValueError: multi\n"
"    line\n"
"detail"
msgstr ""

msgid ""
"The last three lines (starting with :exc:`ValueError`) are compared against "
"the exception's type and detail, and the rest are ignored."
msgstr ""

msgid ""
"Best practice is to omit the traceback stack, unless it adds significant "
"documentation value to the example.  So the last example is probably better "
"as::"
msgstr ""

msgid ""
">>> raise ValueError('multi\\n    line\\ndetail')\n"
"Traceback (most recent call last):\n"
"    ...\n"
"ValueError: multi\n"
"    line\n"
"detail"
msgstr ""

msgid ""
"Note that tracebacks are treated very specially.  In particular, in the "
"rewritten example, the use of ``...`` is independent of doctest's :const:"
"`ELLIPSIS` option.  The ellipsis in that example could be left out, or could "
"just as well be three (or three hundred) commas or digits, or an indented "
"transcript of a Monty Python skit."
msgstr ""

msgid "Some details you should read once, but won't need to remember:"
msgstr ""

msgid ""
"Doctest can't guess whether your expected output came from an exception "
"traceback or from ordinary printing.  So, e.g., an example that expects "
"``ValueError: 42 is prime`` will pass whether :exc:`ValueError` is actually "
"raised or if the example merely prints that traceback text.  In practice, "
"ordinary output rarely begins with a traceback header line, so this doesn't "
"create real problems."
msgstr ""

msgid ""
"Each line of the traceback stack (if present) must be indented further than "
"the first line of the example, *or* start with a non-alphanumeric character. "
"The first line following the traceback header indented the same and starting "
"with an alphanumeric is taken to be the start of the exception detail.  Of "
"course this does the right thing for genuine tracebacks."
msgstr ""

msgid ""
"When the :const:`IGNORE_EXCEPTION_DETAIL` doctest option is specified, "
"everything following the leftmost colon and any module information in the "
"exception name is ignored."
msgstr ""

msgid ""
"The interactive shell omits the traceback header line for some :exc:"
"`SyntaxError`\\ s.  But doctest uses the traceback header line to "
"distinguish exceptions from non-exceptions.  So in the rare case where you "
"need to test a :exc:`SyntaxError` that omits the traceback header, you will "
"need to manually add the traceback header line to your test example."
msgstr ""

msgid ""
"For some exceptions, Python displays the position of the error using ``^`` "
"markers and tildes::"
msgstr ""

msgid ""

msgid "Option Flags"
msgstr ""

msgid ""
"A number of option flags control various aspects of doctest's behavior. "
"Symbolic names for the flags are supplied as module constants, which can be :"
"ref:`bitwise ORed <bitwise>` together and passed to various functions. The "
"names can also be used in :ref:`doctest directives <doctest-directives>`, "

"option."
msgstr ""

msgid ""
"The first group of options define test semantics, controlling aspects of how "
"doctest decides whether actual output matches an example's expected output:"
msgstr ""

msgid ""
"By default, if an expected output block contains just ``1``, an actual "
"output block containing just ``1`` or just ``True`` is considered to be a "
"match, and similarly for ``0`` versus ``False``.  When :const:"
"`DONT_ACCEPT_TRUE_FOR_1` is specified, neither substitution is allowed.  The "
"default behavior caters to that Python changed the return type of many "
"functions from integer to boolean; doctests expecting \"little integer\" "
"output still work in these cases.  This option will probably go away, but "
"not for several years."
msgstr ""

msgid ""
"By default, if an expected output block contains a line containing only the "
"string ``<BLANKLINE>``, then that line will match a blank line in the actual "
"output.  Because a genuinely blank line delimits the expected output, this "
"is the only way to communicate that a blank line is expected.  When :const:"
"`DONT_ACCEPT_BLANKLINE` is specified, this substitution is not allowed."
msgstr ""

msgid ""
"When specified, all sequences of whitespace (blanks and newlines) are "
"treated as equal.  Any sequence of whitespace within the expected output "
"will match any sequence of whitespace within the actual output. By default, "
"whitespace must match exactly. :const:`NORMALIZE_WHITESPACE` is especially "
"useful when a line of expected output is very long, and you want to wrap it "
"across multiple lines in your source."
msgstr ""

msgid ""
"When specified, an ellipsis marker (``...``) in the expected output can "
"match any substring in the actual output.  This includes substrings that "
"span line boundaries, and empty substrings, so it's best to keep usage of "
"this simple. Complicated uses can lead to the same kinds of \"oops, it "
"matched too much!\" surprises that ``.*`` is prone to in regular expressions."
msgstr ""
