Unit Testing with Typemock

Unit Testing ASP.NET? ASP.NET unit testing has never been this easy.

Typemock is launching a new product for ASP.NET developers – the ASP.NET Bundle - and for the launch will be giving out FREE licenses to bloggers and their readers.

The ASP.NET Bundle is the ultimate ASP.NET unit testing solution, and offers both Typemock Isolator, a unit test tool and Ivonna, the Isolator add-on for ASP.NET unit testing, for a bargain price.

Typemock Isolator is a leading .NET unit testing tool (C# and VB.NET) for many ‘hard to test’ technologies such as SharePoint, ASP.NET, MVC, WCF, WPF, Silverlight and more. Note that for unit testing Silverlight there is an open source Isolator add-on called SilverUnit.

The first 60 bloggers who will blog this text in their blog and tell us about it, will get a Free Isolator ASP.NET Bundle license (Typemock Isolator + Ivonna). If you post this in an ASP.NET dedicated blog, you'll get a license automatically (even if more than 60 submit) during the first week of this announcement.

Also 8 bloggers will get an additional 2 licenses (each) to give away to their readers / friends.

Go ahead, click the following link for more information on how to get your free license.

Comments are the true revealer of a bad coder

Comments that are in the code of the application that you have inherited maintenance of can sometimes very quickly reflect the quality of the codebase. In this case there is obviously a bit of confusion around the subtlety and use of the cast, as and is C# operators. Yes, there is also a grammatical error. And no, I have not removed any code from inside the if block - that is all there was.

if (payment is CreditCardPaymentDto)
{
    // For some reason casting this outside the if statement throws and exception                        
    CreditCardPaymentDto creditPayment = (CreditCardPaymentDto)payment;                       
}

Quotes that may indicate your workplace practices waterfall methods

The functional specs will be released to the development team once they are signed off later this week. You can start development next week.

To be fair it was Monday, so I would potentially have up to 4 days as development team lead to prepare the team. </sarcasm>

I guess I'll have to spend the first couple of weeks of development time working out what we are developing...

Don't take shortcuts on script tags!

This problem annoyed me for longer than I would have hoped recently - even though I have seen it before and spent a frustrating time 'fixing' it. I added a script reference (the first for the page) to the head of a html page and lazily wrote it as

<script type="text/javascript" src="scripts/jquery-1.3.1.js" />

Well this broke the ScriptManager, which couldn't hook up the postback methods for the UpdatePanels on the form. Hmm that's odd, even an empty .js file included this way cause a javascript error on page load such as "this._form is null" or "__doPostBack is not defined". And then something twigged from a not-so-distant project and there it was

<script type="text/javascript" src="scripts/jquery-1.3.1.js"></script>

Lesson: Don't take shortcuts when writing script tags!

Dynamic Data Changes - EnableQueryStringSelection

With the release of .Net 3.5 Framework SP1, the Dynamic Data tools have changed slightly. If you setup a site with a pre-SP1 version of Dynamic Data then this issue may have bitten you.

Runtime error - "Type 'System.Web.DynamicData.DynamicDataManager' does not have a public property named 'EnableQueryStringSelection'."

This flag on the DynamicDataManager enabled that manager to ensure that when a control such as GridView is associated with another control such as DetailsView that one would update when the other changed and vice-versa. One of the downsides of this behaviour is that your associated control had to be supported by the DynamicDataManager to be able to participate in the synchronisation - so many 3rd party controls missed out. Also all registered controls participated in the synchronisation from the Url.

To reenable this behaviour in SP1 use the DynamicDataManager.RegisterControl(Control control, Boolean setSelectionFromUrl) overload when registering the controls. When true is specified that control will get its selection from the Url. So there is now a lot more flexibility in defining which control is managed from the url, instead of all registered controls being managed.

VS2008 and .Net 3.5 SP1 released

Today Microsoft released the RTM of Visual Studio 2008 and .Net Framework 3.5 Service Pack 1.

What a great milestone! Hopefully this signals a new level of maturity and stability in these two technologies. Some organisations that I have associated with have been somewhat reticent to embrace .Net 3.5 as it is still perceived as too bleeding edge.

That aside, .Net Framework 3.5 has a great uptake in developer participation due to the exciting new framework and language features that it introduces. There is great buzz in the development community around MVC, Linq-To-Sql, Dynamic Data, Lamba expressions, ASP.Net AJAX, support for Astoria, ASP.Net Entity Framework, partial methods and so on. The speed at which these new technologies and frameworks are appearing is very rapid. What's more is that these features have led to whole new areas of application and platform design options that are easier to implement, reuse and maintain.

I believe this is a really exciting time to be involved in using these tools to develop applications. It reinvigorates the community.

What changes in SP1 do you think will be most beneficial to you?
