Initialize collections

[Bernd]

Hi folks,

I am trying to use JustMock to mock a SharePoint collection (the real thing cannot be used as it fails without a SharePoint context). I cannot figure out how to add items the collection. Here is my code.

var uut = Mock.Create<SPRoleDefinitionBindingCollection>();

var role = Mock.Create<SPRoleDefinition>();
Mock.Arrange(() => role.BasePermissions)
    .Returns(SPBasePermissions.ViewUsageData | SPBasePermissions.EditListItems | SPBasePermissions.DeleteListItems);
uut.Add(role);

var result = uut.ContainsPermission(SPBasePermissions.DeleteListItems);
Assert.IsTrue(result);

I would like to add the SPRoleDefinition instance called role to the SPRoleDefinitionBindingCollection. The uut.Add call is obviously being ignored, which is indicated by the fact that uut.Count is zero. I would expect this to work...

Can you help?

Thanks in advance and kr, Bernd.

Hi Bernd,
Thanks again for sending the issue. Here you can create a fake list of SPRoleDefinition and use it in DoInstead and Returns to simulate add items in the following way:

    var role = Mock.Create<SPRoleDefinition>();
    var uut = Mock.Create<SPRoleDefinitionBindingCollection>();

    IList<SPRoleDefinition> roles = new List<SPRoleDefinition>();

    Mock.Arrange(() => role.BasePermissions).Returns(SPBasePermissions.ViewUsageData | SPBasePermissions.EditListItems | SPBasePermissions.DeleteListItems);
    Mock.Arrange(() => uut.Count).Returns(() => roles.Count);
    Mock.Arrange(() => ((IEnumerable) uut).GetEnumerator()).Returns(() => roles.GetEnumerator());

    Mock.Arrange(() => uut.Add(role)).DoInstead((SPRoleDefinition r) => roles.Add(r));
    Mock.Arrange(() => uut.Contains(role)).Returns((SPRoleDefinition r) => roles.Contains(r));

    uut.Add(role);

    Assert.IsTrue(uut.Count == 1);
    Assert.IsTrue(uut.Contains(role));

    bool inLoop = false;

    foreach (SPRoleDefinition spRoleDefinition in uut)
    {
        inLoop = true;
    }

    Assert.IsTrue(inLoop);

In addition i am delegating the GetEnumerator call for the target SPRoleDefinitionBindingCollection to the custom list which is invoked during foreach and gets the item added during uut.Add
