Submitting forms in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main purpose of submitting a form in Selenium?

Submitting a form in Selenium simulates the user action of sending form data to the server, triggering form processing and navigation.

beginner

Which Selenium WebElement method is commonly used to submit a form?

The submit() method is used on a WebElement inside a form to submit the form.

beginner

How can you submit a form by clicking a button in Selenium?

You can locate the submit button element and use the click() method to submit the form, just like a user would.

intermediate

What happens if you call submit() on an element that is not inside a form?

Calling submit() on an element outside a form will throw an IllegalStateException because Selenium expects the element to be inside a form.

intermediate

Why is it important to wait for page load or response after submitting a form?

Waiting ensures the test does not proceed before the page updates, preventing flaky tests and allowing verification of the result after submission.

Which Selenium method submits a form directly?

A get()

B sendKeys()

C click()

D submit()

The submit() method submits the form that contains the element.

What must be true about the element when calling submit()?

A It must be inside a form element

B It must be a button

C It must be visible

D It must have an ID attribute

The element must be inside a form; otherwise, submit() throws an exception.

How can you submit a form by simulating a user click?

A Use <code>submit()</code> on the button

B Use <code>sendKeys()</code> on the form

C Use <code>click()</code> on the submit button

D Use <code>get()</code> on the form

Clicking the submit button with click() simulates user form submission.

Why should tests wait after submitting a form?

A To allow page load or response

B To save CPU resources

C To avoid exceptions

D To clear form fields

Waiting ensures the page has loaded or responded before continuing the test.

What exception occurs if submit() is called on an element outside a form?

A ElementNotInteractableException

B IllegalStateException

C TimeoutException

D NoSuchElementException

IllegalStateException is thrown because the element is not inside a form.

Explain how to submit a form in Selenium using Java. Include methods and best practices.

Think about both direct and user-like ways to submit forms.

Describe why waiting after form submission is important in automated tests.

Consider what happens if the test moves on too quickly.

Practice

1. In Selenium Java, which method is used to submit a form on a web page?

easy

A. submit()

B. click()

C. sendKeys()

D. getText()

Solution

1. Step 1: Understand form submission in Selenium

   The submit() method is designed specifically to submit forms in Selenium.

2. Step 2: Differentiate from other methods

   Methods like click() simulate clicking but do not necessarily submit forms; sendKeys() inputs text; getText() retrieves text.

3. Final Answer:

   submit() -> Option A

4. Quick Check:

   Form submission method = submit() [OK]

Hint: Use submit() to send form data, not click() [OK]

Common Mistakes:

• Using click() instead of submit() to send form
• Confusing sendKeys() with form submission
• Trying to submit without locating form element

2. Which of the following is the correct way to submit a form using Selenium WebDriver in Java?

easy

A. driver.findElement(By.id("formId")).submit();

B. driver.submit(By.id("formId"));

C. driver.findElement(By.id("formId")).click();

D. driver.findElement(By.id("formId")).sendKeys("submit");

Solution

1. Step 1: Locate the form element correctly

   Use findElement(By.id("formId")) to get the form element by its ID.

2. Step 2: Call submit() on the form element

   Calling submit() on the form element sends the form data.

3. Final Answer:

   driver.findElement(By.id("formId")).submit(); -> Option A

4. Quick Check:

   Correct syntax = driver.findElement(...).submit() [OK]

Hint: Call submit() on the form element, not on driver [OK]

Common Mistakes:

• Trying to call submit() directly on driver
• Using click() instead of submit() on form
• Sending keys 'submit' instead of calling submit()

3. What will happen when the following Selenium Java code runs?

WebElement input = driver.findElement(By.name("username"));
input.sendKeys("user1");
input.submit();

medium

A. Only the input field is cleared but form is not submitted.

B. An exception is thrown because submit() cannot be called on input elements.

C. The form containing the input field is submitted with 'user1' as username.

D. The page reloads without submitting any data.

Solution

1. Step 1: Identify element and actions

   The code finds an input field named "username", enters "user1" text, then calls submit() on that input element.

2. Step 2: Understand submit() behavior on child elements

   Calling submit() on any child element inside a form submits the entire form containing that element.

3. Final Answer:

   The form containing the input field is submitted with 'user1' as username. -> Option C

4. Quick Check:

   submit() on input submits parent form [OK]

Hint: submit() on input submits its parent form [OK]

Common Mistakes:

• Thinking submit() only works on form elements
• Expecting submit() to clear input instead of submitting
• Assuming submit() throws exception on input elements

4. Consider this Selenium Java code snippet:

WebElement form = driver.findElement(By.id("loginForm"));
form.click();
form.submit();

What is the main issue with this code?

medium

A. submit() must be called before click() on the form.

B. submit() cannot be called on a form element.

C. The form element is not located correctly.

D. Calling click() on the form element may cause unexpected behavior before submit.

Solution

1. Step 1: Analyze click() on form element

   Calling click() on a form element is unusual and may trigger unexpected UI behavior or errors.

2. Step 2: Confirm submit() usage

   Calling submit() on the form element is correct and will submit the form.

3. Final Answer:

   Calling click() on the form element may cause unexpected behavior before submit. -> Option D

4. Quick Check:

   click() on form is risky; submit() is correct [OK]

Hint: Avoid click() on form; use submit() directly [OK]

Common Mistakes:

• Thinking submit() cannot be called on form
• Assuming click() is needed before submit()
• Ignoring potential side effects of clicking form

5. You want to submit a form that has no id or name attribute but contains a submit button with class "submit-btn". Which Selenium Java code correctly submits the form?

hard

A. driver.findElement(By.className("submit-btn")).submit();

B. driver.findElement(By.className("submit-btn")).click();

C. driver.findElement(By.tagName("form")).submit();

D. driver.findElement(By.tagName("button")).submit();

Solution

1. Step 1: Locate the submit button by class

   Since the form lacks id or name, find the submit button using its class "submit-btn".

2. Step 2: Call click() on the submit button element

   Calling click() on the submit button simulates pressing the button, which submits the form.

3. Final Answer:

   driver.findElement(By.className("submit-btn")).click(); -> Option B

4. Quick Check:

   click() on submit button triggers form submission [OK]

Hint: Submit form by clicking the submit button [OK]

Common Mistakes:

• Using submit() instead of click() on submit button
• Trying to submit form by tagName without verifying uniqueness
• Calling submit() on button tag which may not be inside form
