Why form testing validates user workflows in Selenium Java - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to open the browser and navigate to the form page.

Selenium Java

WebDriver driver = new ChromeDriver();
driver.[1]("https://example.com/form");

Drag options to blanks, or click blank then click option'

Aget

BfindElement

CsendKeys

Dclick

Attempts:

3 left

💡 Hint

Common Mistakes

Using click() instead of get() causes runtime errors.

Using sendKeys() is for typing, not opening pages.

The get method opens the given URL in the browser.

2fill in blank

Complete the code to find the username input field by its name attribute.

Selenium Java

WebElement username = driver.findElement(By.[1]("username"));

Drag options to blanks, or click blank then click option'

AclassName

Bid

Cname

DtagName

Attempts:

3 left

💡 Hint

Common Mistakes

Using id locator when the element has no id attribute.

Using tagName selects all elements of that tag, not a specific input.

The name locator finds elements by their name attribute, which is common for form inputs.

3fill in blank

hard

Fix the error in the code to enter text into the password field.

Selenium Java

WebElement password = driver.findElement(By.id("password"));
password.[1]("mySecret123");

Drag options to blanks, or click blank then click option'

Aclick

BsendKeys

CgetText

Dsubmit

Attempts:

3 left

💡 Hint

Common Mistakes

Using click() does not enter text.

Using getText() reads text, does not enter it.

The sendKeys method types text into input fields.

4fill in blank

hard

Fill both blanks to submit the form and wait for the success message.

Selenium Java

driver.findElement(By.id("submitBtn")).[1]();
new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.[2](By.id("successMsg")));

Drag options to blanks, or click blank then click option'

Aclick

BvisibilityOfElementLocated

CpresenceOfElementLocated

DsendKeys

Attempts:

3 left

💡 Hint

Common Mistakes

Using sendKeys() to submit the form instead of click().

Waiting for visibilityOfElementLocated may fail if element is present but hidden.

Clicking the submit button sends the form. Then waiting for presenceOfElementLocated ensures the success message appears.

5fill in blank

hard

Fill all three blanks to verify the success message text after form submission.

Selenium Java

String message = driver.findElement(By.id([1])).getText();
assertEquals([2], message, [3]);
driver.quit();

Drag options to blanks, or click blank then click option'

A"successMsg"

B"Form submitted successfully!"

C"submitBtn"

D"Error occurred"

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong element id causes NoSuchElementException.

Using incorrect expected text causes assertion failure.

The element with id "successMsg" contains the message. We check it equals the expected success text. Finally, we close the browser.

Practice

1. Why is form testing important in validating user workflows?

easy

A. It ensures users can complete tasks step-by-step without errors.

B. It only checks if the form looks good visually.

C. It tests the speed of the website loading.

D. It verifies the server hardware performance.

Solution

1. Step 1: Understand the purpose of form testing

   Form testing focuses on checking if users can fill out forms correctly and complete workflows without issues.

2. Step 2: Identify what form testing validates

   It validates input fields, buttons, error messages, and the overall flow to ensure smooth user experience.

3. Final Answer:

   It ensures users can complete tasks step-by-step without errors. -> Option A

4. Quick Check:

   Form testing = Validate user workflow [OK]

Hint: Form testing checks user steps, not just appearance [OK]

Common Mistakes:

• Confusing form testing with UI design testing
• Thinking form testing checks server speed
• Ignoring error message validation

2. Which Selenium Java code snippet correctly submits a form after filling an input field with id username?

easy

A. driver.findElement(By.name("username")).sendKeys(); driver.submit();

B. driver.findElement(By.id("username")).click(); driver.submit();

C. driver.findElement(By.id("username")).sendKeys("user1"); driver.findElement(By.id("submit")).click();

D. driver.findElement(By.className("username")).sendKeys("user1"); driver.findElement(By.id("submit")).submit();

Solution

1. Step 1: Fill input field correctly

   Use sendKeys("user1") on element found by By.id("username").

2. Step 2: Submit form by clicking submit button

   Click the submit button found by By.id("submit") using click().

3. Final Answer:

   driver.findElement(By.id("username")).sendKeys("user1"); driver.findElement(By.id("submit")).click(); -> Option C

4. Quick Check:

   Correct locator and actions = driver.findElement(By.id("username")).sendKeys("user1"); driver.findElement(By.id("submit")).click(); [OK]

Hint: Use sendKeys then click submit button [OK]

Common Mistakes:

• Calling sendKeys without arguments
• Using submit() on wrong element
• Using incorrect locators like className for id

3. Given this Selenium Java code, what will be the output if the form submission shows a success message with id successMsg?

driver.findElement(By.id("email")).sendKeys("[e-mail]");
driver.findElement(By.id("submitBtn")).click();
String message = driver.findElement(By.id("successMsg")).getText();
System.out.println(message);

medium

A. [e-mail]

B. Empty string

C. NoSuchElementException error

D. Success! Your form has been submitted.

Solution

1. Step 1: Understand the code flow

   The code fills the email field, clicks submit, then reads the success message text.

2. Step 2: Identify expected output

   The success message element with id successMsg contains the text "Success! Your form has been submitted." which is printed.

3. Final Answer:

   Success! Your form has been submitted. -> Option D

4. Quick Check:

   getText() returns success message [OK]

Hint: getText() prints visible message after submit [OK]

Common Mistakes:

• Confusing input value with message text
• Expecting element not present error
• Assuming empty string if message missing

4. What is wrong with this Selenium Java code snippet for form testing?

driver.findElement(By.id("password")).sendKeys();
driver.findElement(By.id("loginBtn")).click();

medium

A. sendKeys() is called without input text, causing an error.

B. Using id locator is incorrect for password field.

C. click() should be called before sendKeys().

D. No error, code works fine.

Solution

1. Step 1: Check sendKeys usage

   sendKeys() requires a string argument to input text; calling it empty causes an error.

2. Step 2: Verify order and locators

   Using id locator is correct and click() after sendKeys() is proper order.

3. Final Answer:

   sendKeys() is called without input text, causing an error. -> Option A

4. Quick Check:

   sendKeys needs argument [OK]

Hint: Always pass text to sendKeys() [OK]

Common Mistakes:

• Calling sendKeys() with no arguments
• Clicking before entering text
• Using wrong locator types

5. In a multi-step form workflow, why is it important to validate each step's form before moving to the next?

hard

A. Because Selenium cannot test multiple steps at once.

B. To catch errors early and prevent invalid data from progressing.

C. To reduce the number of test cases needed overall.

D. Because users prefer to fill all steps at once.

Solution

1. Step 1: Understand multi-step form workflow

   Each step collects data that builds on the previous; errors early can block progress.

2. Step 2: Importance of validating each step

   Validating each step ensures errors are caught early, improving user experience and data quality.

3. Final Answer:

   To catch errors early and prevent invalid data from progressing. -> Option B

4. Quick Check:

   Stepwise validation = catch errors early [OK]

Hint: Validate each step to stop errors early [OK]

Common Mistakes:

• Thinking Selenium limits multi-step testing
• Assuming fewer test cases is better here
• Believing users want all steps at once
