spy

Given the following code snippet, how would you create a Jasmine spyOn test to confirm that doSomething gets called when you run MyFunction ? function MyFunction() { var foo = new MyCoolObject(); foo.doSomething(); }; Here's what my test looks like. Unfortunately, I get an error when the spyOn call is evaluated: describe("MyFunction", function () { it("calls doSomething", function () { spyOn(MyCoolObject, "doSomething"); MyFunction(); expect(MyCoolObject.doSomething).toHaveBeenCalled(); }); }); Jasmine doesn't appear to recognize the doSomething method at that point. Any suggestions? When you

这个模型以前绝对见过，模拟赛的时候开始敲了一个AC自动机，纯属脑抽~ code: #include <bits/stdc++.h> #define N 5000006 #define NN 10005 #define M 100006 #define setIO(s) freopen(s".in","r",stdin) , freopen(s".out","w",stdout) using namespace std; queue<int>q; stack<int>ss; int n,m,cnt,tot; int st[M],ed[M],f[M],lst[M],length[M]; char S[M],str[M],total[N]; struct Node { int tag,f,len; map<int,int>ch; }t[N]; int main() { int i,j; // setIO("char"); scanf("%d",&n); scanf("%s",S+1); scanf("%d",&m); for(i=1;i<=m;++i) { scanf("%s",str+1); int len=strlen(str+1); int p=0; st[i]=cnt+1; ed[i]=st[i]+len-1; for(j=1;j<=len;++j) { int c; total

I'm trying to spy on an Object and I want to stub a method that is called by the constructor before the constructor calls it. My class looks like that: public class MyClass { public MyClass() { setup(); } public void setup() { } } The setup method mustn't be called. Well, how do I spy on this method (and stub setup so that it does nothing)? It works fine with mocking the method but I want to unit test MyClass and so I will need very other method. The reason why need to stub the setup method so that it does nothing: I'm programing a Lego robot (lejos) and I put some code in setup that the robot

I am using Jasmine to test if certain objects are created and methods are called on them. I have a jQuery widget that creates flipcounter objects and calls the setValue method on them. The code for flipcounter is here: https://bitbucket.org/cnanney/apple-style-flip-counter/src/13fd00129a41/js/flipcounter.js The flipcounters are created using: var myFlipCounter = new flipCounter("counter", {inc: 23, pace: 500}); I want to test that the flipcounters are created and the setValue method is called on them. My problem is that how do I spy on these objects even before they are created? Do I spy on

I have seen the service like spypig.com placing a small image in the email and tracking when it is opened and from where. They track city, country, IP address etc. How is this done? How do we know when the mail is opened? And how is the image generated? How is the IP address detected and how is it possible to know location from it? Basically, in the HTML body of your email, there will be an <img> tag that would look like this : <img src="http://www.yoursite.com/tracker.php?id=123456" alt="" /> When someone reads his mail, with images enabled, the email-client will send a request to tracker.php

I want to test whether the following method is called with in my Javascript object constructor. From what I have seen in the Jasmine documentation, I can spy on a constructor method and I can spy on methods after an object has been instantiated, but I can't seem to be able to spy on a method before the object is constructed. The object: Klass = function() { this.called_method(); }; Klass.prototype.called_method = function() { //method to be called in the constructor. } I want to do something like this in the spec: it('should spy on a method call within the constructor', function() { spyOn

I don't understand the difference between Mock, Stub, and Spy in Spock testing and the tutorials I have been looking at online don't explain them in detail. Attention: I am going to oversimplify and maybe even slightly falsify in the upcoming paragraphs. For more detailed info see Martin Fowler's website . A mock is a dummy class replacing a real one, returning something like null or 0 for each method call. You use a mock if you need a dummy instance of a complex class which would otherwise use external resources like network connections, files or databases or maybe use dozens of other objects
