Nit: You could improve the existing test a bit here by switching from hard-coded
strings to the corresponding policy constants, as done in your new test.

[peletskyi, 2015/04/02 15:24:51]

Done.

[bartfab (slow), 2015/04/07 11:37:16]

What you did is great. I had missed it that there is a constant you can use
instead of the magic "4". What I actually meant was to replace the
"RestoreOnStartupURLs" and "RestoreOnStartup" strings with constants though,
which would be a further improvement to the code.

[peletskyi, 2015/04/07 13:14:29]

Done.
