Mocking InnerException of SqlException does not work

[Normen]

Hi there,
I am trying to mock the InnerException-Property of a Mocked SqlException.

[Test]
public void SqlException_Example()
{
    var sqlEx = Mock.Create<SqlException>();
    sqlEx.Arrange(ex => ex.Class).Returns(20);
    sqlEx.Arrange(ex => ex.InnerException).Returns(new Exception("My Test"));

    Assert.IsTrue(Mock.IsProfilerEnabled);
    Assert.That(sqlEx.Class, Is.EqualTo(20));
    Assert.That(sqlEx.InnerException, Is.Not.Null); //<-- Fails
}

I will be grateful for any help.

Hi Normen,
Thanks again for contacting us.

The property "InnerException" belongs to mscorlib. Therefore, you first need to initialize it. I did it in the following way and working as expected.

static UnitTest1()
{
    Mock.Replace<SqlException, Exception>(x => x.InnerException).In<UnitTest1>(x => x.TestMethod1());
}

[TestMethod]
public void TestMethod1()
{
    var sqlEx = Mock.Create<SqlException>();
    sqlEx.Arrange(ex => ex.Class).Returns(20);
    sqlEx.Arrange(ex => ex.InnerException).Returns(new Exception("My Test"));

    Assert.IsTrue(Mock.IsProfilerEnabled);
    Assert.AreEqual(sqlEx.Class, 20);
    Assert.IsNotNull(sqlEx.InnerException); //<-- works
}
