// 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 */
