Selenium's core purpose is to automate browsers. The official documentation states that its primary use case is web application testing, but it is not limited to this; repetitive web management tasks can also be automated.
The main capabilities consist of three components: Selenium WebDriver provides language-specific bindings for driving browsers, suitable for creating robust browser regression automation suites and tests, and can scale and distribute scripts across multiple environments; Selenium IDE is a standalone application that enables simple record and playback of browser interactions, suitable for quickly creating bug reproduction scripts or assisting exploratory testing; Selenium Grid is used to distribute and run tests across multiple machines, managing multiple environments from a central point, making it easy to run tests against a large number of browser and operating system combinations.
How to use: Choose the component based on your goal. Use WebDriver when you need to write maintainable regression tests; use IDE when you need quick record and playback; use Grid when you need to scale tests across machines and environments. The official page provides a Getting Started entry point; specific installation commands and code examples are not provided in the given material.
Applicable scenarios include web application regression testing, bug reproduction, exploratory testing assistance, and automation of repetitive web management tasks.
