SQLServer UnitTesting in Visual Studio - DROP DATABASE [MyDb] - sql-server

Question

I've set up a Unit Test project in Visual studio for my SQL Server project.
The test itself work, and the setup includes deploying that database. My problem is that I want to have a "clean slate" test, and every time I run a test, the data accumulates.
I tried manually calling a 'DROP DATABASE' from the SqlDatabaseSetup.cs, but it seems that I don't have a DataConnection at this point.
[TestClass()]
public class SqlDatabaseSetup
{
[AssemblyInitialize()]
public static void InitializeAssembly(TestContext ctx)
{
var q = ctx.DataConnection.CreateCommand();
q.CommandText = "DROP DATABASE MyDb;";
q.ExecuteNonQuery();
// Setup the test database based on setting in the
// configuration file
SqlDatabaseTestClass.TestService.DeployDatabaseProject();
SqlDatabaseTestClass.TestService.GenerateData();
}
}
Is there anyway to indicate that the DB should be flushed first (without manually calling DELETE FROM XX for every table), or is there a way I can pass through a command to do that for me?

Answer 1

The solution was as follows :
[AssemblyInitialize()]
public static void InitializeAssembly(TestContext ctx)
{
// Setup the test database based on setting in the
// configuration file
try
{
var conn = SqlDatabaseTestClass.TestService.OpenExecutionContext();
var cmd = conn.Connection.CreateCommand();
cmd.CommandText = "use master; ALTER DATABASE [MyTestDb] SET SINGLE_USER WITH ROLLBACK IMMEDIATE;DROP DATABASE MyTestDb;";
cmd.ExecuteNonQuery();
}
catch
{
}
SqlDatabaseTestClass.TestService.DeployDatabaseProject();
SqlDatabaseTestClass.TestService.GenerateData();
}
