Setting up End-to-End testing (for Nyssetutka.fi) using Nightwatch.js, Selenium and ChromeDriver and running the tests in a headless Chrome instance was super easy.
What I always find hardest to figure it when it comes to unknown systems, it’s ‘how things fit together’. These project might have great documentation, but how the ecosystem plays together is usually left as an exercise for the reader. This happened to me again when diving into frontend testing. I figured out how to get nightwatch+selenium-standalone+chromedriver+chrome working somehow, without fully understanding each part in the puzzle. I went with Nightwatch because I like the syntax and it seems one of the obvious options nowadays. That works until I updated some dependencies and broke everything again. So I took some time to figure out how these things fit together and what is really needed for me tests. I’ve learned that Selenium is the godmother of modern frontend testing. It’s a framework with bindings for multiple languages. To decouple the server from the actual browsers, it invented “Selenium RC” as a protocol. That lead to the development of the WebDriver W3C standard which replaces Selenium RC is newer versions and is implemented for the most common browsers (Chrome -> Chromedriver, Firefox -> FirefoxDriver).
WebDriver is an open source tool for automated testing of webapps across many browsers. It provides capabilities for navigating to web pages, user input, JavaScript execution, and more. ChromeDriver is a standalone server which implements WebDriver's wire protocol for Chromium. ChromeDriver is available for Chrome on Android and Chrome on Desktop (Mac, Linux, Windows and ChromeOS).
I was encountering an odd problem and needed to see what files were in a Jenkins workspace. For a freestyle job, this is easy; you just click on “workspace.”
Pipelines are made up of multiple steps that allow you to build, test and deploy applications. Jenkins Pipeline allows you to compose multiple steps in an easy way that can help you model any sort of automation process.
To fully recognize the benefits of Jenkins Pipeline, this Refcard will help you build a Jenkins Declarative Pipeline and manage it with Blue Ocean. Learn the details of creating a Jenkinsfile, branches and pull requests, pipeline fundamentals, and using the agent directive. In addition, understand post actions for cleaning up files, archiving results, or sending notifications; and access a complete syntax reference.
