Adding a Step to a library involves creating a file with the name of our Step, adding our code to a call method inside that file, and replacing the appropriate code in our Jenkinsfile with the new Step calls. So, what do you think? For example, you might write a standard step to deploy an application, or perform a code review. It thoroughly describes the general concept, but some details may not be so apparent when trying to pull pieces of your script code into a library. There is a setting for the libraries called 'Include Library changes in job recent changes' which we have unchecked, but that doesn't seem to be respected. It consists of the following folder structure: straight from the docs root +- src Groovy source files +- org +- foo +- Bar. Very important in this era of microservices where each microservice has a pipeline of its own.

Jenkins Pipeline

Most things you can do in Java, you can do in Groovy. It lives in its own repo from which it is retrieved and executed by Jenkins. Then, if this is the master branch and a change was just merged, then it checks if the developer wants an automatic deployment. MissingPropertyException: No such property: qools for class: groovy. Usually, in your team or organization, you will have to execute the tests the same way multiple times - there are various environments, different groups reuse the same test automation frameworks, etc. Looking at the above code snippets we can clearly see that they are very similar - the try-finally, junit and archiveArtifacts steps. Now, what shall we put inside? So if you want to regain a little bit of sanity when managing your Jenkins pipelines, keep on reading! Obviously it does not happen under simple conditions, since I have never heard of it before, tests covering this functionality all pass, etc.

In this case, the specified GitHub repository would be loaded, from the master branch, using an anonymous checkout. It was related to the workspace root directory found in the Advanced button on the right hand side of the manage Jenkins link. Plugin Information View Pipeline: Shared Groovy Libraries for more information. At a certain point you will want to introduce abstractions. If like me, you prefer to control the whole pipeline from the code, you can load the library using Library annotation.

Afterwards the deployment is verified via the health status monitor of the application. Provides capability to extend pipeline scripts using shared libraries. Taking a look at the above code snippets in the context of extracting them to an external function, parametrizing the paths used in them is probably a good idea. As of this writing the latest version is 1. Fortunately there is a way to run tests for the pipeline code, be it scripts or typed classes. It seems that the default value for this in the latest releases has changed.

Jenkins Pipeline

} The way we run tests The next element on our list is how we run specific tests in our pipelines. It is starting to get out of hand for us. Just like with any other library that we would implement when creating steps for Jenkins, it is always a good idea to stop for a second and think about possible and relatively cheap extension points. The main driver for establishing these best practices is ease of use when it comes to implementation. Hi Juan, I was trying to implement the same concept into my shared library activities to handle repetition of code. It is necessary to ensure subsequent curl requests share the cookiejar. These tests will lean towards unit tests even though the unit boundaries for pipelines are not that clear.

Once the configuration is in place, the project will build quite easily. Should you want to leverage the power of groovy to perform such a call, this should be done by calling a separate groovy script from an sh or bat step. Our next post will be about how you can actually get out of Groovy coding in Jenkins pipelines and write pipelines in any language you want! The branch for implicitly loaded libraries can also be overridden using the Library annotation. Thanks for your help Best Regards J-L. This way, you can simply reference the library with Library 'your-lib' :. Warning: this dog will chase its own tail. A Pragmatic Approach In practice, we have found that storing all pipeline functions in vars is actually quite a bit more practical.

A typical use case is that you have many projects that are built in the similar way. This post is a continuation of the tutorial. Hi Yoni, I am glad you liked the post. Finding candidates for a library When thinking about moving parts of your pipeline to a library, imagine creating a similar script in the next project or creating an additional pipeline that reuses bits of the one you already have. This is because pipelines scripts kept, e.

Jenkins shared libraries: tested

jenkins shared library

How would we like to adjust triggering the above code? BasePipelineTest class BasicPipelineTest extends BasePipelineTest { Before void before { super. You can define a shared library within a Jenkinsfile, or you can configure the library using the Jenkins web console. No I am talking about filesystem permissions, not Jenkins permissions. The following examples are aimed primarily at testing groovy compilation, execution and emulated interpretation by Jenkins. Please let me know if you need more info to reproduce the behavior, if I recall correctly that library is pretty standard nothing special with it. We will leave the dir steps out of the library though - in my opinion, it is the responsibility of given pipeline to know the context of a given stage and navigate correctly through its workspace. The workshop will assume that.
