Verify inline functions with reified and crossinline params

[Kristiyan Petrov]

Is it possible to verify a function like this?

inline fun <reified T> Socket.emitTyped(event: String,
                                        objectToEmit: Any?,
                                        crossinline success: (response: T) -> Unit,
                                        crossinline error: (reason: String) -> Unit)

@kristiyanP, unfortunately, it is not possible as no method with bytecode is produced. I heard this question already few times. It would require a totally different approach to solve. For example writing an annotation processor. I am thinking about it, as this can probably make it possible to run on Android devices.

Why not wrap it in a regular function and test that instead? Wouldn't that work?

inline fun <reified T> Socket.emitTyped(event: String,
                                        objectToEmit: Any?,
                                        crossinline success: (response: T) -> Unit,
                                        crossinline error: (reason: String) -> Unit) {
    // Some code which gets inlined
}

fun <T> emitTypedWrapper(event: String,
                                        objectToEmit: Any?,
                                        success: (response: T) -> Unit,
                                        error: (reason: String) -> Unit) {
    // This will be replaced with code inside the inline function by compiler
    Socket.emitTyped(event, objectToEmit, success, error)
}

Now write your tests with the wrapper function.
