Additionally, it can provide warnings about potential issues such as excessive nesting, deep inheritance, and large functions. Visual Studio Code Metrics also provides code coverage, which measures the amount of code that is actually used in a project. With this information, developers can identify areas of their code that need to be improved or refactored.
To get started with code metrics, you’ll need to have either Visual Studio 2008 Team System Development Edition or Team Suite. Open Visual Studio, and then open the project you want to calculate code metrics against. In this article, we’ll talk about code metrics in Visual Studio Team System . We’ll start out by identifying the different code metrics available, and talk about good and bad values for each. Then we’ll dive into an example of how to run code metrics in Team System.
When you generate CM on your code it produces such things as Maintainability Index, Cyclomatic Complexity, Class Coupling, Inheritance depth and lines of code. In order to display code metrics of a Microsoft Visual Studio 2010 project or a VS2010 solution, open Visual Studio 2010. It’s great tool which provides several additional metrics like number of methods, number of fields, number of variables in class and etc.
Visual Studio Code Metrics for VS2010
I will explain explain each one of them in details in individual posts so that you have better understanding of each of them. In this post lets have a look how to start seeing code metrics of your applications. Maintainability Index is a software metric that indicates how maintainable the source code is. A high value of the Maintainability Index means better code maintainability. Different color codes are used to signify the maintainability index.
Code Metrics is one of the important software measures that give you an insight of your code maintainability and complexity. As a developer when you are writing your code, you must adhere those boundary values of metrics to ensure your code is well written, understandable and maintainable. In short, Code Metrics is an important measure that let us understand the complexity and maintainability of the code. Occasionally I look at the code metrics in visual studio for my solution. My maintainability is usually pretty high with exception to some obvious classes . The only time I really ever find the cyclomatic complexity and class coupling values high is again, on classes that I expect to see high values on.

It indicates how easy it should be to understand and modify the code. The maintainability index metric can be used as an overall quality indicator and this index will be calculated with combination of cyclomatic complexity and lines of code metric results. Visual Studio’s Code Metrics features are very powerful and, when used, ensure your code is written properly and well maintained. Every enterprise has their own standards of code maintenance, but I would recommend running the code metrics tool regularly for better code quality and good practice.
- Learn Tips and Trick for Development and stay ahead of the game.
- In your question I read that you have expected certain values at certain points.
- Over the last few posts we have covered all the different types of a code metrics and internal of each of the items.
- It is often used to estimate the size and complexity of a program, as well as to assess the amount of effort required to develop the software.
This includes both comments and blank lines, as well as executable lines of code. It is also important to note that this number does not include any generated code, such as code generated by a compiler or code generated by an IDL compiler. The total number of lines of code can then be used to compare projects of different sizes and complexities.
Measure Your Code Using Code Metrics
You can run / rerun the metrics from the tool itself by clicking on the “Calculate Code Metrics for Solution” button itself. Incase if you want to focus any specific types of Metrics values, you ASP NET MVC Developer Job Description Template can choose and select those columns and deselect the rest. A single tip can improve the productivity of your work while coding. Learn Tips and Trick for Development and stay ahead of the game.
It is often used to estimate the size and complexity of a program, as well as to assess the amount of effort required to develop the software. Additionally, it can be used to measure the progress of a project, or to determine how much code has been written, modified, or deleted. Counting lines of code in Windows can be done manually, or through the use of specialized software. Whether you’re calculating code metrics against code you’ve written, or using it to identify potential issues in code you have to maintain, you’ll find code metrics an extremely useful tool. The exported excel will have the filter enabled for the class coupling with the value defined.
Visual Studio 2008 Code Metrics
Once Project level metrics is calculated, you can drill down to each and individual method to analyze their metrics data. Please also note that it is possible to balance the complexity calculation for the project / team / personal taste by adjusting the relevant configuration entries . One of your existing projects must be taken, the number of lines must be determined, and the time required to code the lines must be reduced. You can get a very accurate representation of the rate of linear movement per hour from this metric. If you want to know how many hours you’ve spent with that specific language, multiply your total metric by it. Overall, this project appears healthy, and should be easy to maintain.
Using code metrics, you can isolate the potential trouble spots in the code early, giving you plenty of time to refactor the problem sections. Class coupling is a measure on how one class is connected or dependent with another class. Good practice is to always implement fewer dependent classes or a low class coupling.
This one is relatively simple; it indicates the approximate number of lines of code written in a program. The count is based on the intermediate code generated by the Framework. A developer should design methods so that there are fewer lines of code.
Visual Studio Code Metrics
However I don’t know whether it’ll work for the languages you have mentioned. The TFS Work item will have the details of code https://bitcoin-mining.biz/ metrics information including code metrics values. Here is a sample exported excel data from the code metrics results.
Maybe the design could be improved to prevent complexity in certain areas. Code metrics are most useful for large code bases where you may not be able oversee or even know about each part of the code. Usually these situations happen when you have to work with code you have not written yourself. The thing with any metric is that you can only manage what you measure.
The filter feature helps a developer easily find the code block or function they need to work on. As you can see, the maintainability index for the entire project is a 7, indicating this project will be very difficult to maintain. It has high numbers for both cyclomatic complexity and class coupling. The DoEvenMoreWork method looks to be the worst off, with a maintainability index of 0. It’s obvious this code has a lot of problems, and will require some serious reworking in order to make long-term maintainability feasible.
