    <p>Honestly, I couldn't tell you the best way to do that in MSpec. But I've experienced a similar class explosion problem with MSpec when using it in similar circumstances. I don't know if you have ever tried RSpec. In RSpec contexts and specifications are built up within the confines of executable code. What that means is you can create a data structure, iterate on it, and create several contexts and specs using one block of code. This becomes especially handy when you are trying to specify how something based in mathematics behaves (prime factors,tic tac toe, chess, etc...). A single pattern of behavior can be specified across each member of a set of given and expected values.</p> <p>This example is written in NSpec, a context/spec framework for C# modeled after RSpec. I purposefully left a failing spec. I just went down this kata far enough to find a place to use iteration. The failing spec forces you to resolve the shortcomings of the naive implementation.</p> <p>Here's another example of prime factor kata: <a href="http://nspec.org/#dolambda" rel="nofollow">http://nspec.org/#dolambda</a></p> <p>Output:</p> <pre><code>describe Knight when moving 2 back and 1 left when a knight at D4 is moved to B3 knight position should be B3 when a knight at C4 is moved to A3 knight position should be A3 - FAILED - String lengths are both 2.

    1. POHow would you avoid context/class explosion in this case with MSpec?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
