node.js - How to test socket.io events being called with sinon.spy -

-
first of all, i'm trying test second time function being called returns correct value. more specific, i'm trying test second time event received socket.on() returns correct value. i know sinon.spy() can detect whether function being called or not. seems not working socket.io events. i'm trying test example, var socketio = io.connect(someurl); socketio.on(eventname, cb); if event 'connect' called. tried var spy = sinon.spy(socketio, 'on'); assert(spy.witharg(eventname).called); but says it's never being called. furthermore, if i'd test data in callback function right or not, example var socketio = io.connect(someurl); socketio.on(eventname, function(data) { data.should.equal(something); }); is possible test that?

lisp - Change variable defined in let function -

given following let function: (let ((foo (list b c d))) foo) how can modify list foo? (let ((foo (list b c d))) ;some code foo) so returned foo looks eks: '(some new list) or (a b modified d) i tried (set) foo still return original list. you can use setf modify specific element in list. (let ((foo (list 'a 'b 'c 'd))) (setf (third foo) 'modified) foo) this return (a b modified d) . or if want replace whole variable, can assign directly setq : (let ((foo (list 'a 'b 'c 'd))) (setq foo (list 'some 'new 'list)) foo) you can't use set lexical variables, special variables.

i'm trying plot piecewise function below using if statements, , keep getting the error: unexpected '}' in "}" message. of braces seem fine me, don't know coming from. advice here appreciated. (also, first time i've done in r, please bear me). x.values = seq(-2, 2, = 0.1) n = length(x.values) y.values = rep(0, n) (i in 1:n) { x = x.values[i] if (x <= 0) { y.values = -x^3 } else if (x <= 1) { y.values = x^2 } else { y.values = sqrt(x) } y.values[i] = y } this can done without loop taking advantage of fact r functions vectorized. for example: library(tidyverse) theme_set(theme_classic()) dat = data.frame(x=x.values) in base r, can do: dat$y = with(dat, ifelse(x <= 0, -x^3, ifelse(x<=1, x^2, sqrt(x)))) with tidyverse functions can do: dat = dat %>% mutate(y = case_when(x <= 0 ~ -x^3, x <= 1 ~ x^2, true ~ sqrt(x))) then, plot: ggplot(dat, ae...

this question has answer here: polymorphism: why use “list list = new arraylist” instead of “arraylist list = new arraylist”?
