Introduction
============

This is a full-blown functional test. The emphasis here is on testing what
the user may input and see, and the system is largely tested as a black box.
We use PloneTestCase to set up this test as well, so we have a full Plone site
to play with. We *can* inspect the state of the portal, e.g. using 
self.portal and self.folder, but it is often frowned upon since you are not
treating the system as a black box. Also, if you, for example, log in or set
roles using calls like self.setRoles(), these are not reflected in the test
browser, which runs as a separate session.

Being a doctest, we can tell a story here.

First, we must perform some setup. We use the testbrowser that is shipped
with Five, as this provides proper Zope 2 integration. Most of the 
documentation, though, is in the underlying zope.testbrower package.

    >>> from Products.Five.testbrowser import Browser
    >>> browser = Browser()
    >>> portal_url = self.portal.absolute_url()

The following is useful when writing and debugging testbrowser tests. It lets
us see all error messages in the error_log.

    >>> self.portal.error_log._ignored_exceptions = ()

With that in place, we can go to the portal front page and log in. We will
do this using the default user from PloneTestCase:

    >>> from Products.PloneTestCase.setup import portal_owner, default_password
    >>> browser.open(portal_url)

We have the login portlet, so let's use that.

    >>> browser.open('http://nohost/plone/login_form')
    >>> browser.getControl('Login Name').value = portal_owner
    >>> browser.getControl('Password').value = default_password
    >>> browser.getControl('Log in').click()
    >>> "You are now logged in" in browser.contents
    True
    >>> "Login failed" in browser.contents
    False
    >>> browser.url
    'http://nohost/plone/login_form'

Test 'SEO Properties' in action
===============================

Let's define some helpfull variables:

    >>> page = self.portal["front-page"]
    >>> page_url = page.absolute_url()
    >>> seoprops_url = page_url + "/@@seo-context-properties"

Test wheter 'SEO Properties' tab is visible on front page or not.

    >>> browser.open(page_url)
    >>> "SEO Properties" in browser.contents
    True

Now, let's go to the "SEO Properties" page, make some changes
and click on "Cansel" button.

    >>> browser.open(seoprops_url)
    >>> browser.getControl(name="seo_description_override").value = True
    >>> descr_ctrl = browser.getControl(name="seo_description")
    >>> descr_ctrl.value = "Test change of SEO description"
    >>> browser.getControl("Cancel").click()
    >>> cancel_page = browser.contents
    >>> file("/tmp/seo_props.cancel.html","wb").write(cancel_page)

Clicking on "Cancel" button should lead us to the front-page view.

    >>> browser.url == page_url
    True

No changes must be applied.

    >>> not "Test change of SEO description" in cancel_page
    True

Check whether status message is correct or not?

    >>> "No content SEO properties have been changed." in cancel_page
    True


Let's review other situation. Go to the "SEO Properties" page, make some changes
and click on "Save" button.

    >>> browser.open(seoprops_url)
    >>> browser.getControl(name="seo_description_override").value = True
    >>> descr_ctrl = browser.getControl(name="seo_description")
    >>> descr_ctrl.value = "Test change of SEO description"
    >>> browser.getControl("Save").click()
    >>> save_page = browser.contents

No changes must be applied.

    >>> "Test change of SEO description" in save_page
    True

Check whether status message is correct or not?

    >>> "Content SEO properties have been saved" in save_page
    True
