  // 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 */
