Mock for Microsoft.Practices.EnterpriseLibrary.Data

Trying to find an example for mocking a repository that uses the Microsoft.Practices.EnterpriseLibrary.Data.

C# code. Pretty sure I can create the Unit Test, just cannot determine how to create a Mock for the Database object from Microsoft.Practices.EnterpriseLibrary.Data.

01.using System;

02.using System.Collections.Generic;

03.using System.Linq;

04.using System.Text;

05.using System.Threading.Tasks;

06.using Microsoft.Practices.EnterpriseLibrary.Data;

07.using System.Data;

08.using System.Data.Common;

09.// Other using statements for Models

10.

11.namespace Test.Repository

12.{

13. public class MyDatabaseRepo : IMyDatabaseRepo

14. {

15. // Microsoft.Practices.EnterpriseLibrary.Data 'Database' object

16. readonly Database _database;

17.

18. public MyDatabaseRepo(Database dataSource)

19. {

20. _database = dataSource;

21. }

22.

23. public int InsertNewCustomer(ClientEntity client)

24. {

25. int ClientRecordId = 0;

26. using (DbCommand dbCmd = _da.GetStoredProcCommand("usp_InsertNewCustomers"))

27. {

28. _database.AddInParameter(dbCmd, "@Address1", DbType.String, client.Address1);

29. _database.AddInParameter(dbCmd, "@Address2", DbType.String, client.Address2);

30. _database.AddInParameter(dbCmd, "@City", DbType.String, client.City);

31. _database.AddInParameter(dbCmd, "@State", DbType.String, client.State);

32. _database.AddInParameter(dbCmd, "PostalCode", DbType.String, client.PostalCode);

33. _database.AddOutParameter(dbCmd, "@recordID", DbType.Int32, 0);

34.

35. using (IDataReader reader = _database.ExecuteReader(dbCmd))

36. {

37. reader.Read();

38. ClientRecordId = Convert.ToInt32(dbCmd.Parameters["@recordID"].Value);

39. }

40. }

41.

42. return ClientRecordId;

43. }

44. }

45.}

Mock.Create performance issue with a large interface

Hello,

I want to mock a large interface (~630 methods). The following line takes several minutes and several GBytes of memory:

Dim mJob As IJobInterface = Mock.Create(Of IJobInterface)()

Am I doing something wrong or is there another way to mock that object. I need this mock for every unit test so I need a faster way to do this.

Cheers

Assert, Args.Ignore and Occurs.Never()

An assertion on a mock where you use Args.Ignore() seems to ignore the extra "Occurs.Never()" condition i.e.

// Both of these pass

Mock.Assert(() => mock.Foo(null, null), Args.Ignore(), Occurs.Never());

Mock.Assert(() => mock.Foo(null, null), Args.Ignore());

If you remove the Args.Ignore() and explicitly specify the arguments, Occurs.Never() starts to actually be evaluated.

Recursive mocks - assertions not working correctly

public interface IFoo

{

IBar GetBar(string x);

}

public interface IBar

{

void DoBar(int x);

}

public class Tests

{

[Fact]

public void First()

{

var foo = Mock.Create<IFoo>();

foo.GetBar("a").DoBar(1);

Mock.Assert(() => foo.GetBar("b").DoBar(1));

}

The above test passes, although it should fail.

MockingContainer-generated mocks not compatible with Raise

If I have a MockingContainer and use Get<T> on it, and then try to Mock.Raise on an event of T, I receive an error: Unable to specify which event was deduced in the parameter. If I replace that with the same type generated by Mock.Create<T>, it works.

Cannot raise events on non-eventargs derived EventHandler<T>

I have a simple event which does not derive from event args. It seems that there is no way to raise these events on mocked objects: -

public interface IFoo

{

event EventHandler<string> Message;

}

[Fact]

public void Sample()

{

bool fired = false;

var create = Mock.Create<IFoo>();

create.Message += (o,e) => fired = true;

Mock.Raise(() => create.Message += null, "Test"); //bang

Assert.True(fired);

}

It appears that either (a) you must create a custom delegate rather than using EventHandler<T>, or (b) create a full class that inherits from EventArgs. If so - this is slightly cumbersome to use. It would be much better if there were no restriction that the type of T on EventHandler must derive from EventArgs.

Unintended Call Count mutation for recursive mocks

I have a recursive mock. I'm doing an arrangement on the child mock, but this has an unintended side effect in that the call count of the parent mock is incremented - this should not be happening.

public interface IMyInterface

{

IOther GetOther();

}

public interface IOther

{

int Foo(string test);

}

[Fact]

public void TestMethod()

{

var myInterface = Mock.Create<IMyInterface>();

Mock.Assert(() => myInterface.GetOther(), Occurs.Never());

Mock.Arrange(() => myInterface.GetOther().Foo(null)).IgnoreArguments().Returns(1);

Mock.Assert(() => myInterface.GetOther(), Occurs.Never()); // BANG

}

JML issue with 64-bit builds

I've found an issue between Just Mock Lite when running unit tests that consistently fail, but only under Release build (presumably because of optimized code) and X64 builds with the XUnit test framework. I can't comment on whether this issue occurs under other test frameworks or not, but it definitely goes away under x86 and Debug builds. I have no idea why this happens. Cheers. Here's a sample: -

public class MyClass

{

private readonly MockClass generator;

public MyClass(MockClass generator)

{

this.generator = generator;

}

public void Foo(Object someData)

{

generator.Bar();

}

public interface MockClass

{

void Bar();

}

public class TestClass

{

private readonly MockClass generator;

private readonly MyClass myClass;

public TestClass()

{

generator = Mock.Create<MockClass>();

myClass = new MyClass(generator);

}

[Fact]

public void X64Failure()

{

myClass.Foo(null);

Mock.Assert(() => generator.Bar());

}

Here's the test failure message: -

X64Failure has failed

Occurrence expectation failed. Expected calls in range [1, (any)]. Actual calls: 0

Is JustMock threadsafe?

I'm calling a mock on multiple threads. Sometimes this works just fine. But sometimes the mock call fails with a System.ArgumentException "An item with the same key has already been added.". Here's the end of the stack trace: -

at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)

at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)

at System.Collections.Generic.Dictionary`2.Add(TKey key, TValue value)

at . . (MethodInfo )

at . . (MockInvocation )

at . .Intercept(MockInvocation )

at . .Intercept(IInvocation )

Now I'm not using any dictionaries in my code - is it possible that this is happening somewhere inside the mock?
