While building the Jenkinsfile.groovy for a single project is straightforward, we want to share the logic across multiple C# projects.
I won’t go into the details as I did with my other posts about the process I went through. I moved the logic for Jenkinsfile.groovy into a Jenkins shared library, which is publicly available at Jenkins Library Sample.

We can read the test results and coverage report and include the information in the output if it is available.
Continue readingYou may not currently be using Slack for communication. Still, it is worth considering if you are working in a group (even for school projects) and aren’t using an alternative (beyond email). You can set up a Slack workspace for free and configure it for notifications.
I have a workspace set up for myself that I use with my family for sending lots of random stuff, but I also use it to test integrations I can then apply elsewhere.
Continue readingThe following is inspired by the article from Kris the Coding Unicorn. This is not meant to be a comprehensive suite of tests but a start.
The following steps use the open-source Security Code Scan project, which publishes a tool to NuGet.
Unfortunately, Jenkins doesn’t seem to have a mechanism for visualizing security scans, so the output file is stored as an artifact of the job.
Continue readingCode coverage measures how much of the code is covered when running tests. This is a useful indicator of how effective tests are. One of the features we want to add is to set a minimum bar for testing to increase the quality of our components.
Visual Studio 2022 Community Edition doesn’t automatically include code coverage features out of the box. There are some things we can do to expose it in Jenkins during our build processes, validate the results, and possibly fail the build based on it. Within Visual Studio itself, you can install Fine Code Coverage from the Visual Studio Marketplace or consider tools such as NCrunch.
Adding additional steps to Jenkins won’t take long to get code coverage data and expose it on the Jenkins build page.
Continue readingI have been relying on my previous efforts over five years ago that initially set out our C# builds in Jenkins. However, my next topic, code coverage, was new territory for me.
In the process of working through code coverage, I had the opportunity to discover opportunities to clean up the existing build scripts set out in the previous articles so far.
This article will cover the revisions I’ve made. However, I’ll also update the previous articles that will jump immediately to the result.
Continue readingInitially, when building C# projects, I would have multiple solutions directly referencing the projects to be built. Sometimes, the solutions would have an extraordinary number of projects in them, so I could update them all in parallel.
However, this isn’t an ideal scenario as it makes it easy to blend code and develop tighter dependencies between modules that make future software development harder. By decomposing projects into smaller, more discrete and manageable components, we can increase the rigour around changes we make and have greater confidence in the code quality.
The use of NuGet to store versions of my packages means the applications I build can be small and lean and can work with already-defined mechanisms for publishing and retrieving packages.
I don’t want to publish my personal NuGet packages to a public repository (at least not without developing some confidence in the process first). So I have set up a Sonatype Nexus Repository to host NuGet packages.
I’ll go through the steps for configuring the Nexus Repository, Jenkins, and Visual Studio projects.
Continue readingNow that projects are building, it is incredibly valuable to run tests against the code to validate it.
This is all the more important as in the future: in GitHub we can require that a pull request pass tests and be validated before it is merged into the main branch.
Continue readingThe goal for this stage of development is to get our C# project listed in Jenkins and building. The next iteration will be adding testing.
This step follows the work from CI/CD Scanning GitHub for Repositories from Jenkins, where Jenkins is set up to scan for projects, but it now needs the files required to build.
Continue readingThe next step is to get Jenkins to search GitHub for repositories to build.
I want all the projects in my GitHub repository that qualify to be built automatically, so if I add a new project with the right setup, it will automatically build it.
This can be achieved by having Jenkins scan your GitHub repository to gather all projects. GitHub supports pushing to Jenkins when repositories change, but that is more complicated when Jenkins is behind a firewall and cannot be directly contacted (we’ll be relying on polling in this case instead).
