How to write nunit testing for this method in mvc

# The controller method

public ActionResult TermsandConditionsDeclineValidation(string AccountName)

{

try

{

string strLoanNumber = repository.GetLoanNumber(Session["access_token"].ToString());

int LoanID = repository.GetLoanId(TUtil.CheckString(strLoanNumber, string.Empty), Session["AccountName"].ToString());

int? IsTcAccepted = repository.TermsandConditionsDeclineValidation(TUtil.CheckInt(LoanID, 0));

if (IsTcAccepted == 0 || IsTcAccepted == null)

{

return RedirectToAction("EndSessionPage");

}

else

{

return RedirectToAction("GetClients");

}

catch (Exception ex)

{

Log.WriteError(TUtil.GetMethodExceptionContext(AccountName), ex);

return View();

}

Instead of writing below code in Action method you can create separate method which will return IsTcAccepted baseed on which you can redirect to either EndSessionPage or GetClients:

string strLoanNumber = repository.GetLoanNumber(Session["access_token"].ToString());
int LoanID = repository.GetLoanId(TUtil.CheckString(strLoanNumber,
string.Empty), Session["AccountName"].ToString());
int? IsTcAccepted =
repository.TermsandConditionsDeclineValidation(TUtil.CheckInt(LoanID, 0));

For example

public boolGetIsTcAccepted(){
string strLoanNumber = repository.GetLoanNumber(Session["access_token"].ToString());
int LoanID = repository.GetLoanId(TUtil.CheckString(strLoanNumber,
string.Empty), Session["AccountName"].ToString());
return int? IsTcAccepted =
repository.TermsandConditionsDeclineValidation(TUtil.CheckInt(LoanID, 0));
}

Then you can unit test the method which returns IsTcAccepted by Mocking/Faking Repository.

public boolGetIsTcAccepted(){

    int LoanID = repository.GetLoanId(TUtil.CheckString(strLoanNumber,
    string.Empty), Session["AccountName"].ToString());
   return  int? IsTcAccepted =
    repository.TermsandConditionsDeclineValidation(TUtil.CheckInt(LoanID, 0));

}
