The Code Clone Analyzer in Visual Studio helps us to search duplicate code in the entire project but this is only for Visual Studio Enterprise users. The below Program class has dependency with employee class and EmployeeBusinessService class, so class coupling is increased to 2. The Program class has dependency with employee class, so class coupling is 1.
Connect and share knowledge within a single location that is structured and easy to search. 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 can choose and select those columns and deselect the rest. It would be useful to know what kind of architecture is being used and what type of application you are working on.
Software Engineering Stack Exchange is a question and answer site for professionals, academics, and students working within the systems development life cycle. Each of these are shown at the assembly level then it allows you to drill down to the namespace, class and method level. Another method is to right-click on the solution or project node in Visual Studio 2010 Solution Explorer. Class coupling is a measure of how many dependencies classes in a single class uses.
The Code Metrics features is very powerful to ensure your code is written properly and well maintained. Take the advantages of all additional features of code metrics tool. CodeGuru covers topics related to Microsoft-related How to Become a Front End Developer Front End Web Dev Skills software development, mobile development, database management, and web application programming. Cloud services such as Microsoft Azure and database options including SQL Server and MSSQL are also frequently covered.

While discussion with many developers recently, I found there are lot of developers still didn’t know about this tool or such metrics or why should you use ? Or not clear about it – Well, By taking advantage of these metrics, as a developer, you can understand which classes, which methods, which module should be reworked or refactor. You can identify complexity, potential risks, implementation flaw with in your project. A developer can filter the Code metrics data based on the type of code metrics and by providing min and max value of indexes of the selected metrics. The filter feature helps a developer easily find the code block or function they need to work on.
Some of the common code smells are Long Method, Duplicate Code, Large Class, and Dead Code. For all those queries, we have one solution is ‘CODE METRICS’. Code metrics has really helped me over the years and given me the confidence about my code and improvements in my code as well as inspecting other team members’ code. Another very useful feature of Code Metrics tool is “Export to Excel”; which can be used to export the metrics results into an excel file. For a complete list please check the configuration section in the package.json. For the most commonly used ones, one should do a search for codemetrics.basicsin the settings ui.
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.
Once you run the code metrics, Visual Studio will analyze the selected project/projects and display the code metrics results in the “Code Metrics Results” window. From the result window, you can drill down to each and individual method to analyze their metrics data. Code metrics is a new feature added to the Visual Studio 2008 Team System Development Edition and the Visual Studio 2008 Team System Suite Edition. This feature provides a set of five measurements that give you insight into the health of your code.
The thing with any metric is that you can only manage what you measure. If you never measure anything you’ll never know if there is something that needs to be looked at. You can silence the alarm by The Ultimate List of Interview Questions to Ask Remote Workers adding ignore attributes for that inspection on specific code bases. Just make sure you add the “Reason” so that someone coming in after you doesn’t wonder why we turned off certain inspections.
As a developer, when you are developing applications, how optimistic you are about delivering quality code? There seems to be no built-in code metrics in Visual Studio Code. 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 metrics information including code metrics values. Here is a sample exported excel data from the code metrics results. Once Project level metrics is calculated, you can drill down to each and individual method to analyze their metrics data.

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. Code Metrics is one of the important software measures that give you an insight of your code maintainability and complexity.
- In this figure, we’ve run code metrics over the entire solution, which consisted of a Web site project, a C# project and several Test Projects.
- Taken in isolation, they really aren’t that interesting as you point out, you can already guess at what it’s going to tell you.
- A developer should design methods so that there are fewer lines of code.
- This metric will be calculated at method level and calculation is not the exact line of code we write in C#, it is actually based upon the line number of IL code.
Code metrics can also be a useful tool for analyzing code you may not have written, but have 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.

As per my experience, if you’ll follow coding principles properly like SOLID, DRY, KISS and YAGNI, you can achieve good metrics results. Why developer experience is the key to better software, straight from the… Making statements based on How to make a Cross-Platform Mobile App in Java opinion; back them up with references or personal experience. Once you have the information exported to excel, you can use your data in the way you want. Use export to excel, you will have the same filter applied in the exported sheet.
An Introduction to Interfaces in C#
Code metrics will not run over a Web site project, hence the warning on the first line of results. 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.
A lower value of this metric is preferred because it also increases the complexity in your code. If I were to look at code metrics after there is already a problem then I don’t understand why I need to look, just fix whatever the problem is. Looking before there is a problem usually doesn’t point anything out as the only low maintainability indexes are the examples mentioned above.
This is one area where Continuous Integration/Deployment environments start to add value. You can at least compare the numbers from build to build and see if cyclomatic complexity is increasing rapidly for a piece of code–faster than what you might expect. It’s an indication that perhaps the design might need some tweaking. Another thing that CI/CD tools do is allow you to set thresholds to let you know when something you aren’t expecting to be high suddenly is.
Maybe the design could be improved to prevent complexity in certain areas. Overall, this project appears healthy, and should be easy to maintain. Figure 3 shows you an example of some extremely poor code metrics. Now that you have a basic understanding of the code metrics available in VSTS, let’s look at an example of using code metrics.
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. It gives you a good indication on problem areas in the code.
