Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
NodeMock is a very simple to use mocking framework which can be used to mock functions in JavaScript objects. NodeMock creates mock methods in less code with more expressive manner
Besides it's simplicity it supports following features * Does not need an existing object to create the mock * Verify arguments (we check deeply on objects and arrays to check the validity) * Allow a return to be sent * Callbacks can also be executed with providing arguments * Multiple mock functions in one object * Alter a mock function later on * Method chaining allows creating mocks super easy * Fail support added when calling method that should not be called
Node JS can be used with any testing framework. And we've used it with Nodeunit and it's a perfect match.
npm install nodemock
var nodemock = require("nodemock");
var mocked = nodemock.mock("foo").takes(10, [10, 20, 30]).returns(98);
mocked.foo(10, [10, 20, 30]); // this will return 98
mocked.foo(10); //throws execption
var mocked = nodemock.mock("foo").takes(20, function(){}).calls(1, [30, 40]);
mockes.foo(20, function(num, arr) {
console.log(num); //prints 30
console.log(arr); //prints 40
});
/*
When you invoke foo() nodemock will calls the callback(sits in argument index 1 - as specified)
with the parameters 30 and 40 respectively.
*/
var mocked = nodemock.mock("foo").takes(10).returns(30);
mocked.foo(10); //gives 30
mocked.mock("foo").takes(10, 20);
mocked.foo(10, 20); //gives 30
var mocked = nodemock.mock("foo").takes(10).returns(30);
mocked.foo(10); //gives 30
mocked.mock("bar").takes(true).returns(40);
mocked.bar(true); // gives 40
var mocked = nodemock.fail();
mocked.foo(); //thorws an exception
mocked.bar(); //throws an exception
var mocked = nodemock.mock("foo").fail();
mocked.mock("bar").takes(10);
mocked.foo(); //thorws an exception
mocked.bar(10); //works perfectly
var mocked = require('nodemock').mock('foo');
Creating a object with mock function "foo"
mocked.takes(arg1, args2, ...)
Specify arguments of the function and verify then when calling
mocked.returns(returnValue)
Specify the return value of the function
mocked.calls(callbackPosition, argumentsArray)
Calls a callback at the arguments in index `callbackPosition`
with the arguments specified in the "argumentsArray"
when using this you've to define a function signature as a callback in the argument list
for a callback at index 2 .takes() function will be as,
`mocked.takes(10, 20, function(){})
mocked.mock(methodName)
Used to alter or create a new mock method and add rules to it as usual
mocked.fail()
If calls at very begining afterword any call on the mocked objects will fail
Otherwise current mock method will fails someone called that.
