Selenium
Selenium is an open-source automated testing suite for web applications that enables programmatic simulation of user interactions in a browser. It is compatible with major browsers including Chrome, Firefox, and Safari, supports multiple programming languages such as Java, Python, and C#, and provides core components including WebDriver, IDE, and Grid. It is widely used for web functional testing, regression testing, and cross-browser compatibility verification.
Core Facts
Selenium is the foundational framework for Web UI automation, controls browser behavior based on the WebDriver protocol, and supports multi-language bindings including Python and Java.
The underlying technology of browser automation Agents typically relies on frameworks such as Playwright, Puppeteer, or Selenium.
Selenium was born in 2004 and is the earliest widely adopted browser automation framework.
Timeline (last 90 days)
Selenium appeared earlier and has a mature ecosystem, supporting multiple language bindings; Playwright, launched by Microsoft, has better support for modern JavaScript-rendered pages and has a built-in auto-wait mechanism.
Standard tools such as DuckDuckGoSearchRun or Selenium wrappers are too naive in production environments, treating the internet as a friendly library rather than a heavily fortified fortress.
Traditional UI automation tools (such as Selenium, Appium, Windows UI Automation) rely on developers specifying element locators in advance (such as ID, class name, XPath, Accessibility ID, or control tree path); when an interface redesign causes attribute changes, the locators fail and the script breaks.
Compared with Selenium, Playwright has built-in mechanisms such as automatic waiting and cross-browser parallelism, making it friendlier to modern frontends with dynamic rendering.
Traditional automated testing frameworks such as Selenium and Playwright can simulate browser operations, but reading external emails and extracting dynamic verification codes has always been a difficult barrier to overcome.
Playwright's execution speed is approximately 30% to 50% faster than Selenium.
Selenium is essentially a blank in terms of AI support.
Selenium provides three types of waiting mechanisms: explicit wait, implicit wait, and forced wait (sleep), all of which require developers to manually write code to control.
Traditional E2E tools such as Selenium and Playwright require engineers to manually write scripts to describe user operations.
The automation testing system uses Python as its core language; in UI automation, Playwright has gained popularity due to AI, while Selenium is mainstream at foreign companies.
