Is it needed?

For the sake of code coverage, could you ensure loadStarted() is also send before loadProgress()?

+page.mainFrame()->load(QUrl("data:text/html,This is first page")); 
This is a special case. I would like another load() with a local URL.

Great patch.

> +    SpyForLoadSignalsOrder(QWebPage* page)
> +        : QStateMachine(page)

This is setting the parent of the QStateMachine to page. I think they should be two separate things:
SpyForLoadSignalsOrder(QWebPage* page, QObject* parent= 0);

This is because I am not a fan of:
SpyForLoadSignalsOrder loadSpy(&page);
(parenting something on the stack by a QObject on the stack)

> Source/WebKit/qt/tests/qwebpage/tst_qwebpage.cpp:3195
> +    if (loadSpy.isRunning())
> +        QVERIFY(waitForSignal(&loadSpy, SIGNAL(finished())));

May I suggest to add
QVERIFY(loadSpy.isComplete());
after the if() {} ?
The isComplete() would just return !isRunning();

This is totally superfluous, your test is already correct. But I think that would make it easier for people to read the test.
If someone read the test without knowing anything about how SpyForLoadSignalsOrder works, she will think: the QVERIFY is in a branch, it is probably wrong because loadSpy could have finished before the if().
