YAGNI - 'Poor-mans CQRS' sample application with Entity Framework

.NET, C#, EF, Test

This week Daniel Lang published an interesting article about unnecessary overhead in simple applications.
In a nutshell he proposes an architecture called "Poor-mans CQRS". In his sample he uses an ASP.NET MVC application. The controllers retrieve their required data directly from the database (Query), and updates are performed in service layer (Command).
In this post I will provide a (simple) application, which is based on the Entity Framework. It shows the principle and explains how unit tests can be written without querying a real database.

Code Coverage - Testing with OpenCover and PartCover

Just some days ago, a new code coverage tool was released for the first time. It's called OpenCover. Shaun Wilde created this tool, since PartCover 4 has some issues that are difficult to resolve with the current code base. He describes some of them on his blog.
In this post I will do a comparison between OpenCover and PartCover and show how these tools can be used to get the coverage of unit tests.

PartCover - Coverage of unexecuted methods - Part 2

A few weeks ago I blogged about a problem concerning coverage of unexecuted code in PartCover. The problem was that the report generated by PartCover does not contain any coverage information about uncovered methods. That implicated, that my tool ReportGenerator calculated a wrong coverage quota, since the lines of unexecuted method were considered to be 'not visitable'.
I claimed that it would not be easy to create a workaround for the problem, but actually it isn't that difficult, if you use the right tools.
