In traditional software development approaches, releases are spread out and recur at intervals for every small feature update or bug fix. This dramatically increases the chances of changes getting coupled at the time of deployment. Over time, the problem starts to grow, posing more challenges for an entire team. The worst part is that all processes are manual, and most of these products are developed/tested individually. Needless to say, it becomes more prone to human error. CI/CD is something that solves all this and makes the entire process more manageable and efficient.

The primary goal of every web developer is to build websites with modern and intuitive designs that deliver a smooth and seamless user experience irrespective of which browser they might be using to surf the web. The Internet has witnessed a massive unprecedented boom in recent decades. As of Dec 2018, there are more than 4.1 billion internet users in the world and close to 1.94 billion websites on the web. This consequently implies an expansion in a number of ways websites are being accessed by audiences across the globe. This gives rise to the conundrum of cross browser compatibility which poses a huge challenge to developers. As the number of browsers and their versions are growing at such a rapid pace every year, the task of trying to make a website appear and perform consistently across all browsers is every developer’s nightmare. However, as tedious and time-consuming as cross browser testing may be, it is an imperative phase of every testing cycle. While it is considered nearly impossible to have a website appear and work identical on every browser, there still are a number of ways to deliver consistent user experience and reach a wider target audience. In this article, we’ll explore what cross browser compatibility issues are and why do they occur, how cross browser CSS with feature detection is more favorable to browser detection.

Continuous Integration is considered one of the best practices in development where code integrations are done frequently into the code repository rather than waiting to commit a larger version. As a part of continuous integration, the developer should ensure that integrations should not break the already available code, as being a shared repository would have a significant impact. To solve this problem and show how continuous integration and testing works, we’ll use one of the most popular continuous integration services: Travis CI pipeline.

Jenkins Pipeline is an automation solution that lets you create simple or complex (template) pipelines via the DSL used in each pipeline. Jenkins provides two ways of developing a pipeline- Scripted and Declarative. Traditionally, Jenkins jobs were created using Jenkins UI called FreeStyle jobs. In Jenkins 2.0, Jenkins introduced a new way to create jobs using the technique called pipeline as code. In pipeline as code technique, jobs are created using a script file that contains the steps to be executed by the job. In Jenkins, that scripted file is called Jenkinsfile. In this Jenkins tutorial, we will deep dive into Jenkins Declarative Pipeline with the help of Jenkins declarative pipeline examples.
