// 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 */
