kmock javascript unit test code_javascript skills

Copy code The code is as follows:

(function () {
var KMock = window.KMock = function () {

}
KMock.prototype.setup = function (methodName) {
var instance = this;

instance[methodName] = {
returnAs: function (fn) {
instance["_" methodName] = function () {
instance[methodName].invokeNum;
fn.call();
}
},
isVerify: function (exceptNum) {
if (exceptNum != null) {
return exceptNum == instance[methodName].invokeNum;
}
else {
return instance[methodName] .invokeNum > 0;
}
},
invoke: function () {
instance["_" methodName].call();
},

invokeNum: 0
};
return instance[methodName];
}


})();

//I wrote a mock class myself, It is temporarily used to simulate functions and then determine the number of calls to the function. The following is the usage

///  
///  
///  


module("enter coin"); 

test("enter coin while game has not yet started", function () { 
var flight = new KFlight(); 

var mock = new KMock(); 
mock.setup("draw").returnAs(function () { 
}); 
 
flight.draw = mock.draw.invoke; 


equal(flight.coinNum, 0); 
equal(flight.gameState, 0); 
flight.coinEnter( ); 
equal(flight.coinNum, 0); 
equal(flight.gameState, 1); 


equal(mock.draw.isVerify(1), true); 

});
