Based on all the other answers I created the following solution:

    [Test]
    public void Methodundertest_ExceptionFromDatabase_Logs()
    {
        _mock
            .Setup(x => x.MockedMethod(It.IsAny(), It.IsAny()))
            .Callback(ThrowSqlException);

        _service.Process(_batchSize, string.Empty, string.Empty);

        _loggermock.Verify(x => x.Error(It.IsAny(), It.IsAny()));
    }

    private static void ThrowSqlException() 
    {
        var bogusConn =
            new SqlConnection(
                "Data Source=localhost;Initial Catalog = myDataBase;User Id = myUsername;Password = myPassword;Connection Timeout = 1");
        bogusConn.Open();
    }
