This CSS selectors cheat sheet focuses on different CSS selectors available to make your styling extremely precise and save time & effort of manual coding.

Jenkins pipeline environment variables are global string values, accessed through the env variable, that inject dynamic data like credentials and job parameters into a Jenkinsfile without hardcoding them. Useful built-ins include env, currentBuild for the running build, params for read-only build parameters, and docker for Docker-related functions, while a bat command's output can be captured with returnStdout: true and trimmed.

Release velocity is the pace at which a team safely ships new builds, and it typically stalls on roadblocks like communication gaps between developers and QA, irreproducible bugs, flaky tests, and mismatched staging and production environments. Debugging directly in production with code-level observability closes that loop faster than reproducing issues from scratch.

Is JUnit 4 different than JUnit 5? In this blog, learn the differences in annotations, how to migrate tests from JUnit4, and to execute tests with JUnit 5.

Unlock the secrets to improving website performance and meeting Core Web Vitals. Enhance loading speed, interactivity, and visual stability for success.

Not all Selenium automation testing scenarios should be automated. This blog covers 24 cases where manual testing is more effective.

Nose2 is a Python test runner and the successor to Nose, extending unittest through the plugins branch of unittest2 to detect and execute unit tests automatically. Enabling its built-in plugin runs tests in parallel across multiple processes, and the framework also supports parameterized tests, fixtures, and logging, distinguishing it from both Nose and unittest2.

Achieve faster loading times and save bandwidth with Lazy Load images JavaScript. Learn the methods for implementing Lazy Load images JavaScript in this guide.

Nose is a Python test automation framework that extends unittest, adding automatic test discovery and documentation collection, with version 1.3.7 still widely used even though Nose2 is its official successor. Installing Nose, writing fixtures, and running parameterized and parallel Selenium tests work the same way across a local or a cloud-based Selenium Grid.

Learn to handle browser windows, tabs and pop-ups in Selenium with PHP using getWindowHandle, getWindowHandles and switchTo, with PHPUnit examples.

Explore Jenkins Declarative Pipeline with examples in this comprehensive guide. Learn how to simplify automation using the Jenkins DSL with practical insights.

Selenium test cases run faster by choosing efficient web locators, replacing Thread.sleep() with explicit waits, reusing the existing browser instance across tests, and writing atomic, independent test scripts. Running tests in parallel, upgrading to Selenium 4, executing on a cloud-based Selenium Grid, and disabling image loading also cut overall execution time.

Learn how to execute JavaScript in Selenium PHP with executeScript and executeAsyncScript, using PHPUnit examples that click elements and read page data.
