First day learning Coded UI Test for Visual Studio 2017 Enterprise. I've got a calculator app that has a few tests and they all pass.
Have another doctors surgery management system app with a login screen, username and passwords are stored on the database.
The idea is to have the table data for username and password as the parameters for the assertion.
How do I add the database to the [Test method]?
Heres my code
Login Form
    private void btnLogin_Click(object sender, EventArgs e)
    {
        //Try and open a connection with database and run the code
        try
        {
            //Create new instance of sql connection, pass in the connection string for BayOneSurgerySystem.mdf to connect to database.
            SqlConnection conn = new SqlConnection(@"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\davie\Documents\UniWork\Software Engineering\BayOneSurgerySystem1.0\Database\BayOneSystem.mdf;Integrated Security=True;Connect Timeout=30");
            //Create new instance of SQlCommand and pass in a query to be called to retrieve table data for username and passwords aswell as the connection object.
            SqlCommand cmd = new SqlCommand("SELECT * FROM Users WHERE Username = @username and Password = @password", conn);
            //This passes user input into @username and @password
            cmd.Parameters.AddWithValue("@username", txtBoxUsername.Text);
            cmd.Parameters.AddWithValue("@password", txtBoxPassword.Text);
            //Open connection with database
            conn.Open();
            //Create new instance of dataSet to hold the data retrieved from sql query
            DataSet ds = new DataSet();
            //Create new instance of DataAdpater to retrieve the data pass in Sql command
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            //using DataAdapter fill in dataSet wiht data if user input and stored data matches
            da.Fill(ds);
            //Close the connection now data table is filled with username and password
            conn.Close();
            //declare bool, true if there is a match with database and user input
            bool loginSuccess = (ds.Tables[0].Rows.Count == 1);
            //if login success is true then open menu
            if (loginSuccess)
            {
                /*Change state of enum RoleTypes based on result from dataSet Role_ID column.
                 In UserRole table records are as follows: 
                 Role_ID 1 = PracticeManager
                 2 = Doctor
                 3 = Receptionist*/
                //Print role_ID to console to check that is been set.
                Console.WriteLine(ds.Tables[0].Rows[0]["Role_ID"]);
                try
                {
                    //Condition for the switch statement is: check Role_ID from UserRoles table
                    switch (ds.Tables[0].Rows[0]["Role_ID"])
                    {
                        //if the case is that Role_ID for the user logged in is 1 then run the function etc.
                        case 1:

Thanks in advance!
