Jenkins: Open-source Automation and Continuous Integration
Before we dive into the specifics of the LoadView Plugin for Jenkins, we’ll discuss Jenkins and why is it important.
Jenkins is an open-source automation server built on the Java Virtual Machine (JVM), supporting thousands of plugins for the development, deployment, and automation of software projects. They are the leader in the open-source automation server space. Other companies that provide open-source automation servers are TeamCity, CircleCI, Hudson, Travis CI, Atlassian Bamboo, among many others.
As part of modern software delivery practices, such as shift left testing and continuous integration, developers, testers, and designers all utilize Jenkins to build, deploy, and automate their tests. Over time, as development and testing cycles became shorter and more frequent due to technological advances and the focus on the digital experience, it became apparent that in order to release quality software features – and consistently – teams as a whole needed to become more agile. This meant that testing now “shifted” to the left and happened earlier, typically after the initial code is written. This “test early and often” mantra is especially significant in continuous integration and continuous delivery (CI/CD), where the goal is to be able to consistently and continually release changes.

Continuous integration essentially ditches the need to test from one’s own machine and automatically test every time new code is pushed into shared source repository, which could be multiple time per day. The advantage of continuous integration is that all development work and code can be integrated into the process earlier, helping to identify and fix bugs or errors more quickly and effectively. The quicker you can find and fix software errors, the more likely you won’t have to fix it in production, where it can be more time consuming and expensive.
To extend continuous integration further, teams use continuous delivery practices to automate and control the software release cycles on top of automating the software testing process. Furthermore, teams can employ continuous deployment, which essentially removes the need for almost any human involvement. All changes that pass through your software development stages are automatically released into production.
What is CI/CD?
Continuous integration (CI) and continuous delivery (CD) epitomize a culture, set of operating principles, and collection of practices that allow application development teams to deliver code changes more frequently and reliably. This is known as CI/CD pipeline. CI/CD is one of the best practices for DevOps teams to adopt. It is also an agile methodology best practice, as it allows software development teams to focus on meeting business prerequisites, code quality, and security as deployment steps are automated.
The Difference Between CI and CD
It’s unclear how this conflation of the two terms started. Be that as it may, it’s sufficiently simple to clear up.
Continuous integration is the way toward coordinating code into a mainline code base. In practically all situations today, continuous integration is finished utilizing stages that are structured explicitly for a reason. Executing continuous integration is, in this manner, is as necessary as utilizing the correct tools.
Continuous delivery, on the other hand, essentially sets out to automate the entire software testing cycle and trying to remove as much manual work as possible, which allows developers the time to work on other projects and not have to manage all the individual steps.
Benefits of CI/CD
- Smaller code changes are less complicated (increasingly nuclear) and have less unintended outcomes
- Deficiency disconnection is less complicated and faster
- Interim to the goal, mean time to repair (MTTR), is shorter due to the smaller code changes and faster shortcoming disengagement
- Testability improves because of smaller, explicit changes. These little changes permit increasingly exact positive and negative tests
- Passed time to distinguish and address creation escapes is shorter, with a quicker pace of discharge
- The build-up of non-basic deformities is lower and frequently fixed before other component issues emerge
- Redesigns present smaller units of progress and are less troublesome
CI/CD Uses & Implementation
CI/CD is many strategies that empower application designers to convey code changes all the more much of the time to clients using computerization.
The abbreviation CI/CD alludes to two separate ideas that are commonly utilized together: ceaseless mix and consistent conveyance. Ceaseless coordination alludes to a mechanization procedure that engineers use to fabricate, test, and combine application code changes. Persistent conveyance is the subsequent stage in which the tried code from the ceaseless mix is naturally sent in different situations by a manual trigger. Continuous delivery can likewise represent the ceaseless arrangement, which presents further computerization. In nonstop conveyance, engineers need to push changes to their creation condition physically. By utilizing nonstop organization rather, designers can have application changes consequently sent to any condition. For this conversation, we will just concentrate on the ideas of ceaseless mix and consistent conveyance.
How CI/CD Works
The cutting edge, relentless universe of user improvement requests that various engineers take a shot during a single application happen all the time. When designers are prepared to test their changes in a standard life cycle, they consolidate their code changes on a preordained “combine day.” The blending procedure can be tedious and time-consuming. It turns out to be much more complex if a designer’s change influences another engineer’s change, at last driving the group to rollback or go through hours on bug fixes.
The Continuous Integration Phase
Changing over to a CI/CD process helps designers combine and test code all the more as often as possible, even every day. The nonstop joining stage follows these fundamental steps:
- A designer takes code from the collective archive to chip away at it, perhaps making another branch for another element.
- When the new element is finished, the engineer pushes it back to the typical vault.
- The CI engineer confirms that changes have been made and starts to fabricate and tests the application, guaranteeing that the progressions have not made the application break. The tests center around all out usefulness to guarantee that no piece of the application has been undermined.
- The advancement group is informed of the test outcomes. In the case of disappointment, the group will realize that the new code has caused disappointment and can start to seclude and fix the issue. If the progressions are active, the group proceeds onward to the ceaseless conveyance stage.
The Continuous Delivery Phase
When intensive testing has completed, groups can proceed onward to the non-stop conveyance stage. An engineer must physically activate the conveyance of code. However, the remainder of the procedure is completely programmed. All fundamental communication with web workers, databases, and different administrations is finished with the call of content.
CI/CD at the Edge
CI/CD programming pipelines are especially useful while sending in high-chance conditions. At the edge, there is an absence of physical access that can some of the time make it hard to moderate issues. Utilizing consistent incorporation and ceaseless conveyance diminishes the hazard by supporting little, gradual changes to an application. Issues would then be able to be quickly recognized and alleviated before harming creation conditions.

Jenkins: Building, Testing, & Deploying Code
We touched on Jenkins earlier in this article, but just to reiterate, Jenkins is an open-source automation platform, written in Java, with modules designed for continuous integration purposes. Jenkins is designed for building and testing your product development, always making it more straightforward for engineers to incorporate changes to the project. Likewise, it permits you to ceaselessly convey your product by coordinating with countless testing and organizational innovations.
With Jenkins, associations can quicken the product advancement process through an automation console. Jenkins coordinates improvement life cycle procedures of different types, including manufacture, report, test, bundle, stage, send, static examination, and considerably more. Modules permit the mix of various DevOps stages. If you need to coordinate a specific device, you have to introduce the modules for that instrument.
When Jenkins is Used
The Jenkins console can be used in many different ways, but it is very supportive in Agile because Dev and QA are working side by side. For example, whenever a developer pushes a new code on a version control system, such asGit, Bitbucket, etc., then a job will be triggered to deploy the build within the QA environment. After the successful deployment, automated test suites will trigger and the resulting reports will be sent by Jenkins. Jenkins is very flexible and provides many plugins to help support third-party integrations, and it is also very simple to setup/configure.
Why Jenkins is Used
Continuous integration and continuous deployment concepts have become the backbone of the latest DevOps environment. It not only bridges the gap in the middle of development and operations teams by automating build, test, and deployment of applications, but they have also has made the process much more efficient. In a trend of continuous development, continuous testing, continuous integration, continuous deployment, and continuous monitoring, all processes of project development, a tool like Jenkins is a complete package that fulfills all challenges. It not only makes development life cycles shorter, but also results in greater customer satisfaction that every company wants.
Another major part of Jenkins tool is the Jenkins Pipeline. The Jenkins Pipeline displays an overview about the different jobs running on builds after commits made by developers. It notifies about the tasks Jenkins is currently executing. In the build pipeline, the build can be seen as divided into sections, such as the unit tests, acceptance tests, and packaging, reporting, and deployment, phases. These phases can be performed either in a series, or parallel. If one phase is successful, it automatically proceeds on to the next phase, thus referring to its name ‘Pipeline.’
As several various changes are being committed by different developers at once, it is helpful to know which change is getting tested now, or which change is sitting in line, perhaps due to a failed build. Once the build has passed unit and integration testing, then engineers in test automation services use Jenkins to trigger automation suites and email reports once the job is ended.
The Jenkins console gives us various interfaces and tools to work with in order to automate the whole process. Jenkins is used to build and test your software projects continually making it easier for developers to integrate changes to the project, and making it effortless for users to obtain a fresh build. It also authorizes you to continuously deliver your software by integrating with a large number of testing and deployment technologies.
LoadView Plugin for Jenkins Requirements
Utilizing the LoadView Plugin for Jenkins, performance testing teams can easily incorporate real browser-based load testing into their Jenkins test builds. This ensures that applications are continuously being tested and evaluated over longer periods of time. This allows teams to identity and address errors and bottlenecks before code and applications are pushed into production.
The primary objective of load testing is rather obvious, to define how much workload the system can take before breaking down or stalling, but the process can be much more complex that just that. A solution like LoadView simplifies what used to be a time consuming process. Exposing a system to large amount of load, or virtual users, allows you to reveal weak points of the system with detailed specifics regarding the source of the problem before additional damage is done. Aside from helping to locate issues, load testing also provides performance results through waterfall charts, test results, and benchmarks from comparative tests. It makes it clear when and why the problem occurred and what caused it to happen.
