espionage¶ ↑

A javascript mocking/stubbing framework

stubbing¶ ↑

var obj = {};

obj.stub("foo")
obj.hasOwnProperty("foo") #=> true

obj.stub("foo", 1);
obj.foo() # => 1

obj.stub("bar", 2);
obj.bar() # => 2

obj.stub("foo", function(x) { return x; });
obj.foo()        # => undefined
obj.foo(1)       #=> 1
obj.foo("hello") #=> "hello"

mock expectations / test spies:¶ ↑

var obj = {}

spyOn(obj, function() {
  obj.foo();
  obj.received("foo") #=> true
});

spyOn(obj, function() {
  obj.foo();
  obj.received("bar") #=> false
});
