A practical guide to testing apps on iPhones: code signing, TestFlight builds, the simulator gap, XCUITest in CI, and when only a real iPhone will do.

Dive into the realm of 'Man Vs Machine' in bug discovery after software release. Explore the delicate balance between human intuition and automated precision. Uncover strategies to identify and replicate bugs for a seamless software experience.

Machine learning finds anomalies and defects in test data by learning normal patterns from logs and test results. Learn the ML techniques, benefits, and limits.

Compare 7 best automated UI testing tools for 2026, learn what automated UI testing is, the challenges teams face, and how to pick the right tool.

Struggling with NoSuchElementException errors? Learn Selenium wait for page load strategies like implicit, explicit, and fluent waits for stable tests.

Setting transition height in CSS means animating an element's height property smoothly using the CSS transition shorthand, such as transition: height 0.5s linear paired with a hover state that changes the height value, for example from 250px to 500px. This creates interactive feedback, like an expanding card, that responds visibly when users click or hover over an element.

Visual testing for mobile apps compares screenshots of an app's actual UI against baseline reference images to catch visual bugs, like images obscuring text or form fields that overlap - defects that functional tests never check because they only verify whether features work, not whether they look right.

Optimize testing with Smart Baseline and Overwrite Screenshot features. Streamline workflows and enhance accuracy in managing baselines with Smart UI project settings.

A headless browser runs in Python and Selenium without rendering a visible graphical interface, executing the same page interactions in the background to cut resource use, in one measured example lowering Chrome's CPU consumption from 78% to 44%. Headless Chrome and Headless Firefox are the two browsers set up and driven through Selenium's WebDriver for automated testing and web scraping.

In October, we released new features, including the Intelligent UI Inspector, Google Pixel 8 and 8 Pro on real device cloud, upgrades to App Automation, Smart UI, HyperExecute, and more.

For loop in Robot Framework helps you deal with repetitive tasks, enhancing test coverage while keeping your test cases readable and easy to maintain.

Web scraping with Python extracts website data using BeautifulSoup, Scrapy, and Requests for static pages, and Selenium or Playwright for dynamic ones.

NoSuchElementException is one of the most common exceptions in Selenium, which occurs when an element is not found on the page. This blog post discusses NoSuchElementException, why it occurs, and how to fix NoSuchElementException in Selenium with Java.

Types of mobile apps: learn about the primary, secondary, and industry-specific mobile app types for your needs.

Unlock the potential of CI/CD: Learn the principles, benefits, and tools for streamlined software development. Quality at speed with automation and testing.

The @FindBy annotation in Selenium Java's Page Factory model lets testers declaratively specify how to locate a web element, such as by id, name, xpath, or css, making automation code more readable and maintainable. Using @FindBy also requires calling PageFactory's initElements method in the page object's constructor for the annotation to take effect.

In this insightful webinar, you’ll explore how seamless local and CI testing for AWS applications is with LocalStack.
