How do I use a SQL Server database with Coded UI Test?

Question

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:
                            {
                                Roles.Role = Roles.RoleType.practiceManager;

                            }
                            break;

                                Console.WriteLine("Role type changed to " + Roles.Role);
                            }
                            break;
                        case 3:

                            break;
                        default:
                            break;

                    }
                }//Switch condition cannot be reached then catch exception and print to console.
                catch (Exception ex)
                {
                    Console.WriteLine(ex);
                }


                Console.WriteLine("Logged in.");
                FrmMenu menu = new FrmMenu();
                menu.Show();
                this.Hide();
            }

[Data source (does the connection string go here?), Test method]

Thanks in advance!

Answer 1

Coded UI supports several types of data source including CSV, Excel, SQL and XML. For a CSV data sources and some general information on data driving please read this answer here on Stack Overflow. This (old) web page appears to be the main documentation of data sources. The "Other types" section of the table on that web page refers to an MSDN article which gives connection strings for several other type of SQL database.

For data held in SQL Express use DataSource and TestMethod attributes based on:

[DataSource("System.Data.SqlClient",
            "Data Source=.\\sqlexpress;Initial Catalog=tempdb;Integrated Security=True",
            "Data", DataAccessMethod.Sequential),
 TestMethod]

Other types of SQL database use variations of the above.
