CircleCI Vs Travis CI: Which is the Best CI/CD Tool?

In this post, we will introduce CI/CD by taking reference to two of the most popular tools used in software development today: GitLab vs Jenkins. With their benefits to methods of working, we will explore more of CI/CD and why it is an integral part of SDLC today.



A brief introduction to <a href="https://testsigma.com/continuous-integration#Continuous_Integration:~:text=too%20many%20conflicts.-,Continuous%20Integration%20Vs%20Continuous%20Deployment%20Vs%20Continuous%20Delivery,-Continuous%20Integration%2C%20Continuous" target="_blank" rel="noreferrer noopener">Continuous Integration/Continuous Delivery</a>

When these concepts are attached to one another to work in automation on a project, we call this a pipeline. A “pipeline” because it is serial like a pipe and no state can be jumped or skipped. You cannot achieve continuous delivery when continuous integration is not achieved. However, for this post, we can limit ourselves to just this brief introduction of CI/CD pipelines. Although, with the detailed analysis of GitLab vs Jenkins, we will touch on the concepts at various places.

<h2 id="h-icebreaker-between-gitlab-ci-cd-vs-jenkins">Icebreaker Between GitLab CI/CD vs Jenkins</h2>



While GitLab CI/CD and Jenkins both are exceptionally good software that currently rules the market but there can be an ice-breaking point that can help you decide clearly which tool to choose.



Firstly, GitLab’s main strength comes from being cloud-based and having good monitoring features. Be it branch monitoring or performance monitoring, GitLab has a really good UI and great metric system that help analyze things clearly at any point in software development. This is not true with Jenkins or maybe with any other CI tool currently available. However, it all comes at a price as GitLab comes in free and premium packages. The main point of this section is to let you know that if monitoring and metrics are your priority, your bucks will be well spent on GitLab.



On the other hand, Jenkins is completely free to use and is a popular choice just for this part. As free software, it gives you a lot of things that the majority of paid CI tools do not give. The main strength of Jenkins comes from its plugins, which are thousands in number. As a tester, whatever you may need can be found in a plugin which gives a lot more flexibility. 



Another good thing about having an open-source plugin-based system is that you can build your own if feasible. It has a good UI (which is rare in CI-based systems) and is continuously updated by developers. Jenkins should be your first choice when the team is satisfied with the available plugins, and there are no major requirements that Jenkins can’t suffice. It is also extremely easy to learn and use for a beginner.



<h2 id="h-alternatives-to-gitlab-ci-cd-and-jenkins">Alternatives to GitLab CI/CD and Jenkins</h2>



For people who wish to explore a few more tools other than GitLab and Jenkins for CI capabilities can refer to the following list of five most preferred:

Let us know in the comment section if you are a user of one of these tools and how it compares with GitLab vs Jenkins.



<h2 id="h-conclusion">Conclusion</h2>



The concept of continuous integration and continuous development has seeped too deep into SDLC that even smaller companies of just a few developers also find it relevant. It helps merge code smoothly and run various tests upgrading the application&#8217;s quality and minimizing the chances of errors at the user’s end. 



In this post about Gitlab vs Jenkins, we took two of the most popular tools that help us achieve just that. GitLab CI/CD and Jenkins are equally efficient with uniquely different features that help us make a clear choice between them. 



Starting with why to choose each of them to how to set them up on your machine, I hope this post will help you start your journey with the best <a href="https://testsigma.com/blog/ci-cd-tools/" target="_blank" rel="noreferrer noopener">CI/CD tools</a> in the market.

<h2 id="junit-vs-testng-overview">JUnit vs TestNG &#8211; Overview</h2>



<h3 id="h-what-is-junit">What is JUnit?</h3>



JUnit happens to be among the most popular unit testing frameworks for Java. It offers a simple and effective solution when it comes to writing and running unit tests for Java code. In JUnit, test cases are generally written as Java classes that have methods to test particular units of code—methods, for example, or classes.



Features of JUnit



Annotations: JUnit uses annotations to define test cases, test suites, and expected exceptions.



Assertions: JUnit provides several different assertion methods, such as assertEquals, assertTrue, and assertFalse, to check the correctness of the results being tested.



Test Runners: JUnit comes with built-in test runners for running tests and reporting results.



Fixtures: JUnit has built-in support for the creation and cleanup of fixture objects.



Test Suites: JUnit enables the creation of test suites so that related tests can be executed together. This is a cleaner and simpler approach.

<h3 id="h-what-is-testng">What is TestNG?</h3>



<figure class="wp-block-image size-full"><img loading="lazy" width="798" height="134" src="https://s3.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/2023/09/13142510/TestNG.jpg" alt="TestNG" class="wp-image-47228" srcset="https://s3.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/2023/09/13142510/TestNG.jpg 798w, https://s3.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/2023/09/13142510/TestNG-768x129.jpg 768w" sizes="(max-width: 798px) 100vw, 798px" /></figure>



TestNG is a unit testing framework for Java classes developed to fill in the gaps left by JUnit and NUnit. It introduces some new concepts that were not available in JUnit or NUnit at the time, like groups, flexible configurations for running test cases, and data-driven testing at the test suite level.



Check here &#8211; <a href="https://testsigma.com/blog/testng-vs-cucumber/" target="_blank" rel="noreferrer noopener">TestNG vs Cucumber</a>



Features of TestNG



Annotations: TestNG uses annotations to define test cases, test suites, and test configurations.



Data-Driven Testing: TestNG supports data-driven testing. It allows running the same test with different data sets.



Parallel Testing: TestNG has the capability to execute tests in parallel, which is advantageous for improving performance for large test suites.



Listeners: TestNG equips listeners to customize the way tests are run and how results are reported.



Dependencies: TestNG allows the specification of dependencies between test methods so that they are executed in the right order.

<h2 id="h-why-is-junit-more-popular-than-testng">Why is JUnit More Popular than TestNG?</h2>



Junit is most often more popular than TestNG because of its history as one of the first Java testing frameworks. It is simple and easy to use and very highly integrable with widely used IDEs like <a href="https://www.javatpoint.com/intellij-vs-eclipse" target="_blank" rel="noreferrer noopener">Eclipse and IntelliJ IDEA</a>. 



There are many tutorials available for this, and there is a very large community that supports an ecosystem of plugins and extensions.&nbsp;



The introduction of JUnit 5 has made it more interesting due to new features and flexibility. Besides JUnit 5 close association with the test-driven development (TDD) pattern enforces it as the de facto standard for <a href="https://testsigma.com/blog/unit-testing/" target="_blank" rel="noreferrer noopener">unit testing</a> in Java.



<h2 id="h-can-we-use-junit-and-testng-together">Can We Use JUnit and TestNG Together?</h2>



Even though it is not a common practice, you can use JUnit and TestNG together.



But they are chosen to be used together due to their complementary strengths and widespread adoption within the testing community. While JUnit is renowned for its simplicity and ease of use, TestNG offers advanced features like parameterized testing and parallel execution. Combining both frameworks allows developers to capitalize on the best of both worlds.



<h2 id="h-summary">Summary</h2>



In the comparison of JUnit and TestNG, JUnit is simple, old, and works greatly integrated with IDEs; hence, it is more commonly used for unit testing. On the other hand, TestNG offers advanced features like execution of tests in parallel and dependency testing that are oriented to a more complex test environment.&nbsp;



In the end, however, the choice between the two is an individual thing based on the project and its specific needs as well as the taste of the developer.
