连接到 SQL 服务器数据库进行单元测试时 C# 登录失败

Question

我正在做一个项目，当我试图运行单元测试来检查进度时，我收到一个错误：

Initialization method UnitTestProject.UnitTest1.Init threw exception. System.Data.SqlClient.SqlException: Cannot open database "database" requested by the login. The login failed.
Login failed for user 'User\User1'

我检查过 User1 是 SQL 服务器的所有者，我认为我的连接字符串正确，但我一定遗漏了一些明显的东西，请告诉我:)

我的存储库 class:

public class Repository
{
    private string _connectionString; 

    public Repository()
    {
        _connectionString = configurationManager.ConnectionStrings["database"].ConnectionString;
    }

    public IEnumerable<Person> GetPeople()
    {
        var people = new List<Person>();

        using (SqlConnection connection = new SqlConnection(_connectionString))
        {
            string commandText = "SELECT dbo.People.Id"
                + ", dbo.People.FirstName"
                + ", dbo.People.LastName"
                + ", dbo.People.Height"
                + ", dbo.People.Weight"
                + "FROM dbo.People";

            SqlCommand command = new SqlCommand(commandText, connection);

            try
            {
                connection.Open();
                SqlDataReader reader = command.ExecuteReader();

                while (reader.Read())
                {
                    people.Add(new Person()
                    {
                        Id = reader.GetInt32(0),
                        FirstName = reader.GetString(1),
                        LastName = reader.GetString(2),
                        Height = reader.GetDouble(3),
                        Weight = reader.GetDouble(4)
                    });
                }
            }
            catch (Exception ex) 
            {
                Console.WriteLine(ex.Message);                
            }
        }
        return people; 
    }
}

我在 App.config 中的连接字符串：

add name="database" 
    connectionString="Data Source=localhost;Initial Catalog=database;Integrated Security=true"

我的单元测试：

public class UnitTest1
{
    private Repository _repo; 

    [TestInitialize]
    public void Init()
    {
        _repo = new Repository();
        _repo.ResetDatabase();
    }

    [TestMethod]
    public void GetPeople()
    {
        int count = _repo.GetPeople().Count();
        Assert.IsTrue(count > 0);
    }
}

Answer 1

尝试添加该元素以清除之前可能定义的任何连接字符串：

<connectionStrings>
<clear />
<add name="DBConnection" connectionString="Data Source=xxxxxxxxxxx\xxxxxxxxx;Initial Catalog=xxxxx;Persist Security Info=True;User ID=xxxxxxxx;Password=xxxxxxxx"
     providerName="System.Data.SqlClient" />   
</connectionStrings>

Answer 2

似乎通过 SQL 身份验证创建 SQL 服务器登录，即用户 ID 和密码让我解决了登录问题。

然后我还必须从以下位置更新连接字符串安全性：

Integrated Security=true

至：

User id=admin;Password=password

不幸的是，我现在在运行测试时看到这个错误：

Initialization method UnitTestProject.UnitTest1.Init threw exception. System.Data.SqlClient.SqlException: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) ---> System.ComponentModel.Win32Exception: No process is on the other end of the pipe.

不过，我将从现有的解决方案中尝试：

No process is on the other end of the pipe (SQL Server 2012)
