Provide a way to extend sure

[gabrielfalcao]

So that the code below is valid:

from sure import assertion, chain, chainproperty
from lxml import html


@assertion
def attribute(parent, is_negative, name):  # *args, **kw FTW
    if is_negative:
        return name not in parent.object.attrib
    else:
        return name in parent.object.attrib

@chain
def child(parent, name):  # *args, **kw FTW
    items = parent.object.cssselect(name)
    items.should.have.length_of(1)

    return items[0]

@chainproperty
def having(parent):
    return parent.object

def test_anchors_in_1st_level_headers():
    headers = dom.cssselect("h1")

    headers.should.have.length_of()

    h1 = headers[0]

    h1.should.have.attribute("name").being.equal("api-reference")
    h1.should.have.child("a").having.attribute("href").equal("#api-reference")

Hey Gabriel, great library! 😄

This would be my number one feature request too as I would like to extend sure for testing web applications.

e.g.

response = self.client.get('/')
response.should.render_template('index.html')
response.should.return_code(200)
response.should.contain('welcome to my homepage')

Do you think that you would be able to support such functionality in the near future?

Thanks heaps!

Some basic stuff is already merged to achieve this functionality. However, the PR #117 has some open points which I want to address in the future.

I'm going to close this issue for now!
