The idea behind the Page pattern is that it should capture all the information about a
particular page in your site, so that if, later, you want to go and make changes to that
page—even just simple tweaks to its HTML layout for example—you have a single place
to go and look for to adjust your functional tests, rather than having to dig through
dozens of FTs.
The next step would be to pursue the FT refactor through our other tests. I’m not going
to show that here, but it’s something you could do, for practice, to get a feel for what the
trade-offs between D.R.Y. and test readability are like…
Extend the FT to a Second User, and the “My Lists” Page
Let’s spec out just a little more detail of what we want our sharing user story to be. Edith
has seen on her list page that the list is now “shared with” Oniciferous, and then we can
have Oni log in and see the list on his “My Lists” page, maybe in a section called “lists
shared with me”:
functional_tests/test_sharing.py (ch21l010).
[
...
]
list_page
.
share_list_with
(
'oniciferous@example.com')
# Oniciferous now goes to the lists page with his browser
self
.
browser
=
oni_browser
HomePage
(
self
)
.
go_to_home_page
()
.
go_to_my_lists_page
()
# He sees Edith's list in there!
self
.
browser
.
find_element_by_link_text
(
'Get help'
)
.
click
()
That means another function in our
HomePage
class:
functional_tests/home_and_list_pages.py (ch21l011).
class
HomePage
(
object
):
[
...
]
def
go_to_my_lists_page
(
self
):
self
.
test
.
browser
.
find_element_by_link_text
(
'My lists'
)
.
click
()
self
.
test
.
wait_for
(
lambda
:
self
.
test
.
assertEqual
(
self
.
test
.
browser
.
find_element_by_tag_name
(
'h1'
)
.
text
,
'My Lists'
))
Once again, this is a function that would be good to carry across into
test_my_lists.py
,
along with maybe a
MyListsPage
object. Exercise for the reader!
In the meantime, Oniciferous can also add things to the list:
functional_tests/test_sharing.py (ch21l012).
# On the list page, Oniciferous can see says that it's Edith's list
self
.
wait_for
(
lambda
:
self
.
assertEqual
(
list_page
.
get_list_owner
(),
