-// SigslotTester(s) are utility classes to check if signals owned by an
-// object are being invoked at the right time and with the right arguments.
-// They are meant to be used in tests. Tests must provide "capture" pointers
-// (i.e. address of variables) where the arguments from the signal callback
-// can be stored.
-//
-// Example:
-//   /* Some signal */
-//   sigslot::signal1<const std::string&> foo;
-//
-//   /* We want to monitor foo in some test. Note how signal argument is
-//      const std::string&, but capture-type is std::string. Capture type
-//      must be type that can be assigned to. */
-//   std::string capture;
-//   SigslotTester1<const std::string&, std::string> slot(&foo, &capture);
-//   foo.emit("hello");
-//   EXPECT_EQ(1, slot.callback_count());
-//   EXPECT_EQ("hello", capture);
-//   /* See unit-tests for more examples */
