Webtest

-----

* Revert change to cookies that would add ``"`` around cookie values.

* Added property :meth:`webtest.Response.pyquery` which returns a
`PyQuery <https://pypi.org/project/pyquery/>`_ object.

* Set base_url on ``resp.lxml``

* Include tests and docs in tarball.

* Fix sending in webob.Request (or webtest.TestRequest) objects.

* Fix handling forms with file uploads, when no file is selected.

* Added ``extra_environ`` argument to :meth:`webtest.TestResponse.click`.

* Fixed/added wildcard statuses, like ``status="4*"``

* Fix file upload fields in forms: allow upload field to be empty.

* Added support for single-quoted html attributes.

* `TestResponse` now has unicode support. It is turned on by default
for all responses with charset information. **This is backward
incompatible change** if you rely (e.g. in doctests) on parsed
form fields or responses returned by `json` and `lxml` methods
being encoded strings when charset header is in response. In order
to switch to old behaviour pass `use_unicode=False` flag to
`TestApp` constructor.

-----

* Added method :meth:`TestApp.request`, which can be used for
sending requests with different methods (e.g., ``MKCOL``). This
method sends all its keyword arguments to
:meth:`webtest.TestRequest.blank` and then executes the request.
The parameters are somewhat different than other methods (like
:meth:`webtest.TestApp.get`), as they match WebOb's attribute
names exactly (the other methods were written before WebOb existed).

* Removed the copying of stdout to stderr during requests.

* Fix file upload fields in forms (`340
<https://web.archive.org/web/20120516124643/http://trac.pythonpaste.org/pythonpaste/ticket/340>`_) -- you could
upload files with :meth:`webtest.TestApp.post`, but if you use
``resp.form`` file upload fields would not work (from rcs-comp.com
and Matthew Desmarais).

---

* Fix form inputs; text inputs always default to the empty string, and
unselected radio inputs default to nothing at all. From Daniele
Paolella.

* Fix following links with fragments (these fragments should not be
sent to the WSGI application). From desmaj.

* Added ``force_value`` to select fields, like
``res.form['select'].force_value("new_value")``. This makes it
possible to simulate forms that are dynamically updated. From
Matthew Desmarais.

* Fixed :meth:`webtest.Response.mustcontain` when you pass in a
``no=[strings]`` argument.

---

* Changed the ``__str__`` of responses to make them more doctest
friendly:

- All headers are displayed capitalized, like Content-Type
- Headers are sorted alphabetically

* Changed ``__repr__`` to only show the body length if the complete
body is not shown (for short bodies the complete body is in the
repr)

* Note: **these are backward incompatible changes** if you are using
doctest (you'll have to update your doctests with the new format).

* Fixed exception in the ``.delete`` method.

* Added a ``content_type`` argument to ``app.post`` and ``app.put``,
which sets the ``Content-Type`` of the request. This is more
convenient when testing REST APIs.

* Skip links in ``<script>...</script>`` tags (since that's not real
markup).

-----

* Don't submit unnamed form fields.

* Checkboxes with no explicit ``value`` send ``on`` (previously they
sent ``checked``, which isn't what browsers send).

* Support for ``<select multiple>`` fields (from Matthew Desmarais)

---

* Fix the ``TestApp`` validator's InputWrapper lacking support for
readline with an argument as needed by the cgi module.
