        private StringBuilder verificationErrors;
        private string baseURL;
        private bool acceptNextAlert = true;

        [SetUp]
        public void SetupTest()
        {
            driver = new ChromeDriver();
            baseURL = "http://localhost/";
            verificationErrors = new StringBuilder();
        }

        [TearDown]

        {
            //try

Answer 1

There are a number of strategies you could implement to resolve this:

1. If your login functionality is an API, call this directly to get the cookies and add these to the browser test session. The benefits of this is that it can be reused for any functionality tests that are post-login. You will need to implement a HttpWebRequest but shouldn't be too difficult.

2. If the authentication cookie doesn't change, you could manually get the name and value and incorporate this into your tests by adding it to the session:

   var cookie = new Cookie("CookieName","CookieValue"); driver.Manage().Cookies.AddCookie(cookie);

Our company has option 2 in place and we are in the process of implementing option 1.

Answer 2

The Chrome WebDriver uses a temporary session to do all of its work. So any cookies you have set as your user will not carry over.

If you want to override this, then you can use the user-data-dir property.

ChromeOptions options = new ChromeOptions();
options.addArguments("user-data-dir=/path/to/your/custom/profile");

All of this came from looking at their docs.
