| // 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); |
