gpeipman 1094 days, 5 hours, 51 minutes ago

Writing code that is easy read and test is not something that is easy to achieve. Unfortunately there are still way too much programming students who write awful spaghetti after graduating. But there is one really good book that helps you raise your code to new level – your code will be also communication tool for you and your fellow programmers. (more)

Code Contracts: How they look after compiling?

published 1097 days, 12 hours, 28 minutes ago posted by

gpeipman 1099 days, 5 hours, 35 minutes ago

When you are using new tools that make also something at code level then it is good idea to check out what additions are made to code during compilation. Code contracts have simple syntax when we are writing code at Visual Studio but what happens after compilation? Are our methods same as they look in code or are they different after compilation? In this posting I will show you how code contracts look after compiling. (more)

Enabling XML-documentation for code contracts

published 1100 days, 12 hours, 45 minutes ago posted by

gpeipman 1101 days, 15 hours, 49 minutes ago

One nice feature that code contracts offer is updating of code documentation. If you are using source code documenting features of Visual Studio then code contracts may automate some tasks you otherwise have to implement manually. In this posting I will show you some XML documentation files with documented contracts. (more)

posted by

gpeipman 1102 days, 5 hours, 30 minutes ago

In my previous posting about code metrics I introduced how to measure LoC (Lines of Code) in .NET applications. Now let’s take a step further and let’s take a look how to measure compiled code. This way we can somehow have a picture about what compiler produces. In this posting I will introduce you code metric called number of IL instructions. (more)

Interface contracts – forcing code contracts through interfaces

published 1111 days, 14 hours, 7 minutes ago posted by

gpeipman 1112 days, 7 hours, 9 minutes ago

Sometimes we need a way to make different implementations of same interface follow same rules. One option is to duplicate contracts to all implementation but this is not good option because we have duplicated code then. The other option is to force contracts to all implementations at interface level. In this posting I will show you how to do it using interface contracts and contracts class. (more)

Code contracts and unit tests are not replacements for each other. They both have different purpose and different nature. It does not matter if you are using code contracts or not – you still have to write tests for your code. In this posting I will show you how to unit test code with contracts. (more)
