About Testing Single-selection Autocomplete Fields with Selenium

Selenium allows testing not only the common input fields, but also autocomplete fields, such as this single-selection autocomplete field built with django-autocomplete-light.

For example, here's how you can start typing a country ("germ" for "Germany") and select the autocompleted option to complete the action:

chrome_options = Options()
chrome_options.binary_location = settings.CHROME_BINARY_PATH
chrome_options.add_argument("--disable-search-engine-choice-screen")

browser = webdriver.Chrome(
    service=ChromeService(executable_path=settings.CHROME_DRIVER_PATH),
    options=chrome_options,
)
browser.get("https://example.com/message-form/")

# activate the dropdown with the search field
browser.find_element(
    by=By.CSS_SELECTOR, value="#div_id_country .select2-selection"
).send_keys("\n")

search_field = WebDriverWait(browser, 10).until(
    EC.presence_of_element_located(
        (By.CSS_SELECTOR, "body>.select2-container input.select2-search__field")
    )
)
# type a few letters and press ENTER
search_field.send_keys("germ\n")

browser.quit()

Add some time.sleep(1) calls between the actions to slow down the tests and be able to see what's going on visually.
