Mocking users in ASP.NET MVC 5

Aug 17,2016

So historically unit testing has been a constant non-starter for me. It seems every time I start to write unit tests (whether it’s in an attempt to do some TDD, or just trying produce unit tests for an existing piece of code), I struggle to get over the hump of dependencies that I’ve incidentally placed in my way without even thinking.

Things as simple as getting the current user’s ID using User.Identity.GetUserId() seem harmless, until you realise that in your test the User object will be null.

When dealing with dependencies in the code that you are testing, a common method is to replace these dependencies with a mock. For example, say you have a service which calls off to an external API to get some data; in your test code, you could mock (aka “fake”) that service to just return some fake data rather than calling to the external API.

Moving Entity Framework migrations to another project

Jul 28,2016

This happens to me quite often, because of the way I tend to work with new projects: I’ve created a new web application, got it up and running and set up my initial code first migration, start working on the model (maybe another few migrations for new tables etc) and then realise that I want to move the database to a separate “data layer” project AFTER I’ve already started running the migrations.

So I move my Entity Framework DB context, my model POCOs and my Migrations folder out to the new project, and update all the namespaces to be right (e.g. “SiteName.Data” rather than “SiteName.Web”).

Setting up SendGrid 7.0.0 in ASP.NET

Jun 29,2016

Today I was starting up a new ASP.NET Web Application using the ASP.NET Identity membership system, for a micro site I’m building, and my first task was to get the email confirmation working for accounts (and subsequently to prevent logging in until email has been confirmed). I decided to try out SendGrid rather than using my own SMTP server, mostly because, well, Microsoft told me I should 😉

Getting Ghost Running on Bash on Windows

Jun 19,2016

Well I won’t say that was the easiest process, but I’ve just got an installation of the Ghost blogging platform running on my Bash on Windows system.

I’m never sure if it’s just me or if others experience the same thing, but installations like this just never seem to work as documented for me! All sorts of random errors popped up, I spent 3/4 of my time in Google, some issues I was able to resolve and some I’m not even sure now if I fixed them or if I just “worked around” them so that they will come to bite me in the future!

Culture Club – “The Dream” Come True

Jun 11,2016

CultureClub_RodLaverArena_100616_6Y9A0213-1

I’m not a music reviewer by a long shot, but I really wanted to put emotions and experiences to words after last night’s concert… Last night, June 10 2016, I fulfilled one of my childhood dreams, seeing Boy George and Culture Club live in concert.

Growing up in the 80’s, I had two major musical obsessions (for want of a better word) – Michael Jackson and Boy George. In 1984 I remember watching the Culture Club live from Sydney, which was simulcast on the radio and we recorded it onto a tape which I then played for years. I was 5 when it was on and I was spellbound! I still have memories of the different outfits he wore, which songs he sang in which outfits, and even the place where I had to flip the cassette tape over in my recording. I wish I still had that tape!

Setting Up a Wildcard Certificate for Multiple Sites in IIS 7

Jun 2,2016

You may have come across this before, I know I have…. you have a server running IIS 7 (for example on Windows 2008 R2, which is what my server is), and you want to add multiple sites with certificates without using a unique IP address for each one.

In later versions of IIS such as version 8, you can use Server Name Indication (SNI) right there in the GUI to set the host name to use when someone connects using https. This allows the server to use the same IP address and port (typically 443) for multiple certificates.

Getting going with Bash on Windows

May 22,2016

Patiently I waited, and you know what they say “good things come to those who wait”. When I first heard about the release of Bash on Windows (which is run via the Windows Subsystem for Linux, here is a great overview), I was so excited that you’d think I had nothing else going for me in my life (for the record, I do… I’m just easily excited by shiny things).

Like many, I began my programming years on UNIX, and spent over 10 years primarily working in a command line even while living out the “experience” that was Visual C++ with MFC (I originally said “horror” but ok it wasn’t all that bad – it’s just that the .NET Framework with Visual C# solved so many of the pain points from it that looking back now it seems like it may have been hell!). Anyway, my point is that I used to live in the command line, I love the power of it, love the scripting languages, and let’s be honest, using the command line makes us feel smarter! Come on, it’s true. I’ve tried to recreate the experience since moving to pretty much full-time Windows-based web development using tools like Cygwin, the Git Bash, and a lovely selection of “UNIX-commands for DOS” that I’ve been carting around for years (which seem to have stopped working in Windows 10, anyway), but it’s not the same.

Structured Logging with Serilog in ASP.NET Core

May 18,2016

I recently discovered the beautify of Serilog for logging from my ASP.NET (pre core) web apps, and converted one of my projects across completely to using it (rather than a haphazard, custom file logger that was written by myself years ago). Serilog is a powerful logging library that allows you to do structured logging, allowing you to basically have fields against any log messages (aka log events) containing serialised data – strings, integers, objects, etc.

It’s the objects part that’s really cool – say you are logging an order being placed, you can log the full Order object, and allow easy searching later on by a field such as the OrderId within that object.

My Brief Affair With Microsoft Edge

May 3,2016

Since the dawn of the internet, we have fought over which browser is “better”. I personally have gone from Internet Explorer, to Firefox (a long stopover for a few years), to Chrome for the last couple of years. Like with fashion, though, it seems I’m always a step behind – every time I mention these days that I use Chrome, I prepare myself for an onslaught of “oh that’s so last year”, “you mean the memory hog?”, and “why haven’t you switched to <insert browser name here> yet?”!

Bootstrap validation in ASP.Net MVC

Apr 27,2016

I use Bootstrap in almost every project I build these days. I build up a custom Bootstrap configuration to reduce bloat, and have my workflow down-pat for updating those configurations (which I’ll write about in the near future). I have familiarised myself with it’s ins-and-outs to help ensure I use it to it’s full potential without being overkill, and it has sped up my HTML build time immensely.

One issue I’ve come across before is finding harmony between ASP.Net MVC’s validation and Bootstrap’s validation classes.
