如何将 SQL 服务器数据库与编码 UI 测试一起使用？

Question

第一天学习 UI Visual Studio 2017 Enterprise 的编码测试。我有一个计算器应用程序，有一些测试，它们都通过了。

有另一个带有登录屏幕的医生手术管理系统应用程序，用户名和密码存储在数据库中。

想法是将用户名和密码的 table 数据作为断言的参数。

如何将数据库添加到[测试方法]？

这是我的代码

登录表单

    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:

                //Print role_ID to console to check that is been set.

[数据源（连接串是不是走这里？），测试方法]

Answer 1

Coded UI 支持多种类型的数据源，包括 CSV、Excel、SQL 和 XML。对于 CSV 数据源和一些关于数据驱动的一般信息，请阅读 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，其中提供了几种其他类型的 SQL 数据库的连接字符串。

对于 SQL 中保存的数据，Express 使用 DataSource 和 TestMethod 属性基于：

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

其他类型的 SQL 数据库使用上述的变体。
