I using Iolsator 5.2 to mock a DB call as follows in MSTEST

 public void GetToken_ValidDomainUser_ReturnedToken()
SqlConnection fakeConnection = Isolate.Fake.Instance<SqlConnection>(Members.ReturnRecursiveFakes);
Isolate.WhenCalled(() => BlackMarble.Sabs.WebService.Utils.ConnectionString).WillReturn("mock_connection_string");

SqlCommand fakeCommand = Isolate.Fake.Instance<SqlCommand>(Members.ReturnRecursiveFakes);
SqlDataReader fakeReader = Isolate.Fake.Instance<SqlDataReader>(Members.ReturnRecursiveFakes);
Isolate.WhenCalled(() => fakeCommand.ExecuteReader()).WillReturn(fakeReader);

Isolate.WhenCalled(() => fakeReader.Read()).WillReturn(true);

Isolate.WhenCalled(() => fakeReader.GetInt32(0)).WillReturn(0);
Isolate.WhenCalled(() => fakeReader.GetInt32(1)).WillReturn(1);
Isolate.WhenCalled(() => fakeReader.GetString(2)).WillReturn("Two");

// run the actual command            
var generator = new BlackMarble.Sabs.TokenGenerator.Generator();
var actual = generator.GetToken();

// check the results
Assert.IsNotNull(actual, "No token returned for user");
Assert.AreEqual(actual.UserID, 0);
Assert.AreEqual(actual.CompanyID, 1);
Assert.AreEqual(actual.DisplayName, "Two");
Assert.AreEqual(actual.IsValid(), true);

If it is run with testDriven.NEt it runs fine, but of run via TestDriven.Net and the deugger (i.e. VSHOST is involved) I get a

TypeMock Verification: Method System.Data.SqlClient.SqlConnection.Finalize() was expected but was not called

I tried

Isolate.Verify.NonPublic.WasCalled(fakeConnection ,"Finalize");

But this did not help, I assume I have mde a simple mistake but cannot spot it

Seems like a strange issue especially because you do not use Verify at the code at all...

Are you using the "Isolated" attribute? the error could result from previous test behavior not "cleaned" between tests.

That fixed it, I added the Isolated attribute and all seems OK.

Thanks for the pointer
