No, if you use SetUp(), it will automatically be called for you.

[amogh.bihani, 2014/03/19 13:22:17]

Yes, I had tried that but that still gives runtime error.
I had even tried putting this test in databaseTest in
content/browser/database_browsertest.cc but even there it was giving the same
error. Perhaps using default SetUp() does not give the shell with required
properties [1](lines 32 and 38).

And it is not allowing to put CreateBrowser() in SetUp as well, thats why I had
made a separate method. I had done something like this:
void SetUp() OVERRIDE {
  MediaBrowserTest::SetUp();
  test_shell_ = CreateBrowser();
}

[ddorwin, 2014/03/19 23:28:14]

Somehow, a Shell must have already been created ([1]). Are you saying that Shell
is not usable? Ideally, you could just use shell(), which you inherit from
ContentBrowserTest.

If, for whatever reason, this shell() is not usable, we need to find some other
framework function to use. For example, SetUpOnMainThread() [2].
