// 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. */

// foo.emit("hello");

// EXPECT_EQ(1, slot.callback_count());
