+ \section1 Verifying Signal Emissions
+
+ The QSignalSpy class provides an elegant mechanism for capturing the list
+ of signals emitted by an object. However, you should verify its validity
+ after construction. The constructor does a number of sanity checks, such as
+ verifying that the signal to be spied upon actually exists. To make the
+ diagnosis of test failures easier, the results of these checks should be
+ checked by calling \c QVERIFY(spy.isValid()) before proceeding further with
+ a test.
