- Improve the folder sync selection workflow (LP: #843865).

Improve the sync selection workflow.

To test IRL:

Start the installer. Login with an account that has UDFs or shares. After the "login successful" screen, you should get an overlay over an empty page for a bit, and then the "Folders" page. After that, the "Local folders" page, containing only subscribed UDFs and suggested ones.

Question:

when entering the SyncNowOrLaterPage, where its initializePage calls get_info and the overlay is shown, where is the overlay hid?

* Can you please move the self.patch(os.path, 'getsize', lambda *args: 0) to the testcase setup?
I'm getting this for test_status_after_get_info:

    test_status_after_get_info ... Exception in thread Thread-19:
Traceback (most recent call last):

    self.run()

    total_size += os.path.getsize(fp)
  File "/usr/lib/python2.7/genericpath.py", line 49, in getsize
    return os.stat(filename).st_size
OSError: [Errno 2] No such file or directory: '/tmp/tmp5i98v9/test_file'

* When testing IRL, right after the SSO's "Congratulations" page, I got an empty page with a loading overlay. A few seconds later, the overlay went away, but the page remained empty (I have a screenshot if you need it).
I had to click next on the empty page to get the cloud to computer page.

* And I never for the computer to cloud page :-/.

Sure. I am not sure if that won't break some other test that actually uses getsize though. Will check it.

I believe you!

That one should always be there, even if you get the "cloud to computer" page, it should after that.

separate tests that need getsize into a separate testcase

Make it work right with latest trunk

[Roberto Alsina (ralsina)]

The white page problem was caused by something that merged into trunk interacting badly with this branch. Fixed in revno 63

[Natalia Bidart (nataliabidart)]

The white page problem is indeed fixed but I still don't get the computer-to-cloud page.

So, after I login successfully, I get the congratulations page. Then, the loading overlay (when I click on setup now). Then, the cloud to computer screen, and then, zás, the last page with the "IMAGE GOES HERE" legend.

Am I missing something?

review: Needs Fixing

[Roberto Alsina (ralsina)]

I can't reproduce it. I included it in the build I just uploaded, let's see if it works?

[Natalia Bidart (nataliabidart)]

I tested with a fresh account and it worked, so approving.
