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.

A front-end developer spends quite a bit of his time in fixing script errors. Last month while we were researching about cross browser compatibility issues in JavaScript, we found with an overwhelming consensus, that no matter how perfect the code is, JavaScript errors will always be there. In earlier times, errors were inspected using console.log or alert (). Sprinkling them in every line of the code eventually helped the developer to find out where the error actually is. This was a very time-consuming practice. And in cases of a large application it was more like asking a sculptor to carve out a large stone statue using a pen knife.

What thoughts come to mind when you come across 404/Page Not Found/Dead Hyperlinks on a website? Aargh! You would find it annoying when you come across broken hyperlinks, which is the sole reason why you should continuously focus on removing the existence of broken links in your web product (or website). Instead of a manual inspection, you can leverage automation for broken link testing using Selenium WebDriver.

Modernizr is an open-source and compact JavaScript library that allows developers to craft various levels of experiences for users depending with respect to cross browser compatibility. Modernizr helps developers to perform cross browser testing to check whether new generation HTML5 and CSS3 features are natively supported by their visitor’s browsers or not and to provide dedicated fallbacks for older browsers that are notorious for their poor feature support. Modernizr coupled with the principle of progressive enhancement helps to design cutting-edge websites layer after layer taking advantage of powerful modern web technologies without discarding users still using older browsers like IE.

Automation testing is not always a smooth ride. There are cases where the tests would not work as expected, in which cases debugging the test code (or implementation) is the only way out! Debugging issues in tests become even more difficult if the test suite comprises a large number of test methods.
