Everyone who works in test automation probably heard or used the terms ‘selector’ and ‘locator’. I was thinking, what is the difference between these two? They seem closely related, however they are not actually the same thing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A locator is an abstraction that defines how your automation tool should find an element in the user interface.

We can think of it as an instruction or query that tells the automation engine “here is how to find the element I want to interact with”. Locators are part of the test framework’s API and usually wrap or reference a selector behind the scene.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

in the above example:
– By.ID<\/strong> is the locator strategy (a method for locating elements)
– “login-button”<\/strong> is the selector value
– Together, they form a locator<\/strong> that Selenium can use to find the element

In a nutshell:
A locator = (strategy + selector)<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A selector is a pattern or expression used to identify an element – commonly in the form of CSS selectors, XPath expressions, or accessibility attributes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Selectors come from web technologies, not from the automation framework itself. They’re a web standard and frameworks like Selenium, Playwright, etc use them under the hood to actually locate elements.

A locator wraps or uses a selector internally. When you write a locator, you’re telling the framework which selector type to use and how to apply it.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
