Amended Code For Launching Browser In VS 2015[Screen Shot Of Error List - 02][1].

@alecxe - I have edited the code. But, I still get errors. Thanks very much for your help.


I have done this several times before and it has worked. But for some reason, it is not working. I am using Microsoft Visual Studio 2015 (Community Edition - if that Screen Shot Of Error List -03 helps. I have downloaded the necessary libraries and added the required dependencies in MS/Visual Studio. I have also added a picture of the error list.

Here is the code:

using OpenQA.Selenium.Firefox;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using System.Threading.Tasks;

namespace CV_Library_P.OM_09_2017
    class Valid_Username_Valid_Password

        //Instantiate Firefox Driver
        var driver = new FirefoxDriver();


        //Enter User Name - Email Address
        var user = driver.FindElement(By.Id("cand-login-left"));
        user.SendKeys("[email protected]");

            //Enter Password - Account Pasword
            var pass = driver.FindElement(By.Id("cand-login-left"));

            //Click on Login button

Error List From Launching Browser And Going To Website

  • I installed MS/Visual Studio 2015 on another PC, and, I was able to do a successful build of the code. But, I got the error message: openqa.selenium.webdriverexception ​ {"unable to find a matching set of capabilities"}​​ My google search of the error indicates that it is likely a compatibility issue between Selenium Webdriver and Firefox. I will try and trouble shoot by running Chrome Driver instead. Thanks.

1: Your first error says that: Invalid token class/interface/member declaration
Ans: You have missed basic concept of Encapsulation

  • You have not declared the main method.
  • Every code should be capsulated within the: Class--> Method-->Data

2: Error Method should have a return type.
This error occurs because you have not declared any method within your class.

3: If you are using Selenium 3.0 or greater version then you must have to initialize Firefox-Geckodriver path in your code. Check here, if don't know how to do this.

4: Instead of FirefoxDriver.Navigate().GoToUrl("") use:

driver.get("Your AppURL")
