Interacting with Elements and Forms

Most interaction is click() and send_keys(). The rest of this lesson is the cases where those are not enough, and the failures they produce when the page is not what you assumed.

A form to work with

FORM = """data:text/html,
<form id="signup">
  <label for="email">Email</label><input id="email" type="email">
  <label for="plan">Plan</label>
  <select id="plan">
    <option value="free">Free</option>
    <option value="pro">Pro</option>
    <option value="team">Team</option>
  </select>
  <label><input id="terms" type="checkbox"> Accept terms</label>
  <label><input name="contact" type="radio" value="email" checked> Email</label>
  <label><input name="contact" type="radio" value="sms"> SMS</label>
  <textarea id="notes"></textarea>
  <button type="submit">Create account</button>
  <p id="result"></p>
</form>
<script>
signup.onsubmit = e => {
  e.preventDefault();
  result.textContent = [email.value, plan.value, terms.checked, signup.contact.value,
                        notes.value].join(' | ');
};
</script>"""

data: URLs let these examples run without a server.

Typing and clicking

from selenium.webdriver.support.ui import Select

with webdriver.Chrome(options=opts) as driver:
    driver.get(FORM)

    email = driver.find_element(By.ID, "email")
    email.send_keys("[email protected]")

    Select(driver.find_element(By.ID, "plan")).select_by_value("pro")
    driver.find_element(By.ID, "terms").click()
    driver.find_element(By.CSS_SELECTOR, "input[value='sms']").click()
    driver.find_element(By.ID, "notes").send_keys("deliver after 6pm")
    driver.find_element(By.CSS_SELECTOR, "button[type='submit']").click()

    print(driver.find_element(By.ID, "result").text)

[email protected] | pro | true | sms | deliver after 6pm

send_keys appends — it does not replace. To overwrite an existing value:

    email.clear()
    email.send_keys("[email protected]")
    print(email.get_attribute("value"))

[email protected]

clear() fails on some framework-controlled inputs, because it does not always fire the events the component listens for. The reliable fallback is a select-all:

    from selenium.webdriver.common.keys import Keys
    email.send_keys(Keys.CONTROL + "a")
    email.send_keys("[email protected]")
    print(email.get_attribute("value"))

[email protected]

Selects

    plan = Select(driver.find_element(By.ID, "plan"))

    plan.select_by_value("team")
    print(plan.first_selected_option.text)
    plan.select_by_visible_text("Pro")
    print(plan.first_selected_option.get_attribute("value"))
    plan.select_by_index(0)
    print(plan.first_selected_option.text)
    print([o.text for o in plan.options])

Team
pro
Free
['Free', 'Pro', 'Team']

Select only works on a native <select>. A React or Vue “dropdown” built from divs raises:

selenium.common.exceptions.UnexpectedTagNameException: Message: Select only works on
<select> elements, not on <div>

For those, it is two clicks — open the control, then click the option:

    driver.find_element(By.CSS_SELECTOR, "[data-testid='plan-trigger']").click()
    wait.until(EC.element_to_be_clickable((By.XPATH, "//li[text()='Pro']"))).click()

Checkboxes and radios

    terms = driver.find_element(By.ID, "terms")
    print("before:", terms.is_selected())
    if not terms.is_selected():
        terms.click()
    print("after: ", terms.is_selected())

before: False
after:  True

There is no check() — click() toggles. Guarding with is_selected() makes the step idempotent, which matters when a test re-enters a form or a retry replays the step.

The click that gets intercepted

OVERLAY = """data:text/html,
<button id="save" onclick="result.textContent='saved'">Save</button>
<div style="position:fixed;inset:0;background:rgba(0,0,0,.5)">Cookie banner</div>
<p id="result"></p>"""

with webdriver.Chrome(options=opts) as driver:
    driver.get(OVERLAY)
    driver.find_element(By.ID, "save").click()

selenium.common.exceptions.ElementClickInterceptedException: Message: element click
intercepted: Element <button id="save">...</button> is not clickable at point (412, 380).
Other element would receive the click:
<div style="position:fixed;inset:0;background:rgba(0,0,0,.5)">...</div>
  (Session info: chrome=133.0.6943.16)

The error names the element that stole the click, which is unusually helpful. Three responses, in order of preference:

# 1. deal with the overlay — what a user would do
driver.find_element(By.CSS_SELECTOR, ".cookie-banner .accept").click()
driver.find_element(By.ID, "save").click()

# 2. scroll it into view, when the blocker is a sticky header or footer
driver.execute_script("arguments[0].scrollIntoView({block: 'center'});", button)
button.click()

# 3. last resort — bypass the browser entirely
driver.execute_script("arguments[0].click();", button)

saved

The third works and hides the bug. A JavaScript click dispatches the event directly, ignoring visibility, overlays and disabled styling — so a button no user can reach still passes the test. Use it only when you have confirmed the element is genuinely reachable and WebDriver’s hit test is wrong.

ActionChains

from selenium.webdriver.common.action_chains import ActionChains

with webdriver.Chrome(options=opts) as driver:
    driver.get("https://demo.playwright.dev/todomvc")
    driver.find_element(By.CLASS_NAME, "new-todo").send_keys("buy milk", Keys.ENTER)

    row = driver.find_element(By.CSS_SELECTOR, ".todo-list li")
    destroy = row.find_element(By.CSS_SELECTOR, ".destroy")

    print("before hover:", destroy.is_displayed())
    ActionChains(driver).move_to_element(row).perform()
    print("after hover: ", destroy.is_displayed())

    destroy.click()
    print("remaining:", len(driver.find_elements(By.CSS_SELECTOR, ".todo-list li")))

before hover: False
after hover:  True
remaining: 0

The delete button only exists visually on hover, so the earlier ElementNotInteractableException was correct behaviour, not a Selenium quirk. move_to_element is the fix.

The rest of the vocabulary:

actions = ActionChains(driver)
actions.double_click(element).perform()
actions.context_click(element).perform()                    # right-click
actions.click_and_hold(source).move_to_element(target).release().perform()
actions.drag_and_drop(source, target).perform()
actions.key_down(Keys.CONTROL).click(a).click(b).key_up(Keys.CONTROL).perform()
actions.move_to_element_with_offset(canvas, 40, 20).click().perform()
actions.scroll_to_element(element).perform()

Chained actions queue up and run on perform():

    ActionChains(driver) \
        .move_to_element(row) \
        .pause(0.2) \
        .double_click(row.find_element(By.CSS_SELECTOR, "label")) \
        .send_keys("buy oat milk") \
        .send_keys(Keys.ENTER) \
        .perform()

    print(driver.find_element(By.CSS_SELECTOR, ".todo-list li label").text)

buy oat milk

Double-click to edit, type, enter — one chain. pause() inside a chain is acceptable where a time.sleep between statements would not be: it is bounded, local, and usually needed for a CSS transition the DOM cannot report.

Note that HTML5 drag-and-drop frequently does not work with drag_and_drop, because the browser’s native DnD events are not fully driven by WebDriver. The common workaround is to dispatch the events via JavaScript, or to test the underlying reorder API directly.

File upload

UPLOAD = """data:text/html,
<input id="doc" type="file" multiple>
<p id="names"></p>
<script>
doc.onchange = () => names.textContent = [...doc.files].map(f => f.name).join(', ');
</script>"""

import os, tempfile

with webdriver.Chrome(options=opts) as driver:
    driver.get(UPLOAD)

    path = os.path.join(tempfile.mkdtemp(), "report.csv")
    with open(path, "w") as f:
        f.write("id,total\n1,25.50\n")

    driver.find_element(By.ID, "doc").send_keys(path)
    print(driver.find_element(By.ID, "names").text)

report.csv

Send the path to the input, do not click it. Clicking opens the operating system’s file dialog, which WebDriver cannot see or control — the test hangs until it times out.

Multiple files are newline-separated:

    driver.find_element(By.ID, "doc").send_keys(f"{path_a}\n{path_b}")

a.csv, b.csv

A hidden input needs revealing first — pages often hide the real input behind a styled button:

    driver.execute_script("document.getElementById('doc').style.display = 'block';")
    driver.find_element(By.ID, "doc").send_keys(path)

This is one of the few legitimate uses of execute_script: you are making a real element reachable, not faking an interaction.

Reading state

    el = driver.find_element(By.ID, "email")
    print("text:      ", driver.find_element(By.ID, "result").text)
    print("value:     ", el.get_attribute("value"))
    print("property:  ", el.get_property("value"))
    print("css:       ", el.value_of_css_property("display"))
    print("displayed: ", el.is_displayed())
    print("enabled:   ", el.is_enabled())

text:       [email protected] | pro | true | sms | 
value:      [email protected]
property:   [email protected]
css:        inline-block
displayed:  True
enabled:    True

.text returns only visible text — a hidden element returns "" even when the DOM holds content. Read textContent when you need it regardless:

    print(repr(hidden.text))
    print(repr(hidden.get_attribute("textContent")))

''
'this is present but hidden'

That difference is behind a lot of confusing assertion failures.

Practice

[email protected] | pro | true | sms | deliver after 6pm

selenium.common.exceptions.ElementClickInterceptedException: Message: element click
intercepted: ... Other element would receive the click: <div class="cookie-banner">

before hover: False
after hover:  True

selenium.common.exceptions.TimeoutException: Message: 
# ...after the OS file dialog opened and blocked the session

Next: windows, frames and alerts — the contexts a locator cannot cross.
