Trying to do some unit testing with EF 4.1 code first. I have my live db (SQL Server) and my unit test DB( Sql CE). After fighting (and losing) with EF, Sql CE 4.0 and Transaction support I decided the simplest way to run my test was to:
I have my [Setup] and [TearDown] functions:
[SetUp]
public void Init()
{
System.Data.Entity.Database.SetInitializer(new MyTestContextInitializer());
_dbContext = ContainerFactory.Container.GetInstance<IContext>();
_testConnection = _dbContext.ConnectionString;
}
[TearDown]
public void Cleanup()
{
_dbContext.Dispose();
System.Data.Entity.Database.Delete(_testConnection);
}
Issue is that System.Data.Entity.Database.SetInitializer does not call MyTestContextInitializer after the first test.
Hence the 2nd test then fails with:
System.Data.EntityException : The underlying provider failed on Open.
----> System.Data.SqlServerCe.SqlCeException : The database file cannot be found. Check the path to the database
TIA for any pointers
I got around this by calling 'InitializeDatabase' manually. Like so:
[SetUp]
public void Init()
{
var initializer = new MyTestContextInitializer();
System.Data.Entity.Database.SetInitializer(initializer);
_dbContext = ContainerFactory.Container.GetInstance<IContext>();
initializer.InitializeDatabase((MyTestContext)_dbContext);
_testConnection = _dbContext.ConnectionString;
}
[TearDown]
public void Cleanup()
{
System.Data.Entity.Database.Delete(_testConnection);
_dbContext.Dispose();
}
I think it may be a bug with EF 4.1 RC.
