Learn how to handle hidden elements in Selenium WebDriver with Java: JavaScriptExecutor clicks, getAttribute for text, isDisplayed checks, and hidden dropdowns.

The Actions class in Selenium is an API that simulates complex user interactions, such as mouse clicks, double clicks, right clicks, drag and drop, and keyboard key presses, that cannot be performed with regular WebDriver methods. It works across Java and C# using mouse methods like moveToElement and keyboard methods like sendKeys, keyUp, and keyDown.

Empower your testing with the latest features: GitHub Copilot Extension, Accessibility Automation, and more. Check what’s new at TestMu AI (Formerly LambdaTest) in May!

CSS layouts control how elements size, align, and flow on a page. Learn normal flow, float, positioning, Flexbox, Grid, and multi-column with code examples.

Learn how Sikuli automates dynamic UI tests with image recognition, how to tune match thresholds, and how to keep image based tests off fragile locators.

Debug HTML and CSS errors fast: fix syntax mistakes, cross-browser rendering issues, and misaligned elements using the W3C Validator, CSS Lint, and DevTools.

Automate dynamic UI tests efficiently with Sikuli, HyperExecute, and SmartUI. Learn how to streamline test execution, validate visually, and boost reliability.

The CSS rgba() function sets a color from red, green, and blue values plus an alpha channel from 0 to 1 that controls transparency, with syntax and examples.

Every stage of a DevOps pipeline with a worked example: the components, how to build one that holds up, and the challenges that quietly break pipelines.

Hypothesis testing in Python uses the open-source Hypothesis library to auto-generate test inputs with @given and strategies instead of manual test cases.

Learn how to run Selenium test scripts with our comprehensive guide. Covers installation, configuration, and running your first test script in Java

Parallel testing runs tests at once instead of in sequence. See how to cut CI time with workers, Playwright shards, Selenium Grid, pytest-xdist and TestNG.

Learn how loading times shape user behavior, which Core Web Vitals thresholds matter, and the practical steps that make a website measurably faster.

Geo-distributed real device testing runs an app on physical devices located in the target region to catch network, location and locale issues before launch.

Testing iOS apps on multiple devices means running the same build across different iPhone and iPad models and iOS versions to catch compatibility issues before release, since Apple continuously ships new devices. TestFlight, a free tool from Apple, lets developers distribute beta iOS builds to testers for feedback before an App Store release.

CSS Modules are CSS files whose class and animation names are scoped locally by default, so a build step generates unique hashed class names that prevent one component's styles from leaking into another. Developers import a module, such as Card.module.css, as a JavaScript object, gaining local scope, easier maintainability, reusable styles, and improved CSS specificity in React applications.
