What is a snippet?

A snippet in testing is a small, reusable block of code that performs a specific test task. It can represent:

1. Part of a test scenario: for example, code for user login, page navigation, or form filling.
2. A function or method: encapsulating specific logic, such as retrieving data from a database or making an API request.
3. A step from a BDD scenario: in systems like Cucumber or SpecFlow, this is the implementation of a specific "Given", "When", or "Then" step.

Using snippets improves the cleanliness, readability, and maintainability of automated test code by eliminating duplication and enhancing modularity.

Example of a login snippet for a website:

def login(driver, username, password):
    """Logs into the website."""
    driver.find_element_by_id("username").send_keys(username)
    driver.find_element_by_id("password").send_keys(password)
    driver.find_element_by_id("login-button").click()
