💡 Hint

Common Mistakes

Using By.name or By.className when the element has a unique ID.

Trying to locate by tagName which is too generic.

The id locator is the most direct way to find an element with a unique identifier like "datePicker".

Complete the code to select a date from the date picker by sending keys.

Selenium Java

dateInput.[1]("2024-07-15");

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

AsendKeys

Bclick

Cclear

Dsubmit

💡 Hint

Common Mistakes

Using click instead of sendKeys to enter text.

Using clear without sending keys afterwards.

To enter a date into an input field, use sendKeys to simulate typing.

Fix the error in the code to wait until the date picker calendar is visible.

Selenium Java

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
wait.[1](ExpectedConditions.visibilityOfElementLocated(By.className("calendar")));

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

BwaitFor

Cuntil

DwaitForElement

💡 Hint

Common Mistakes

Using non-existent methods like waitFor or waitUntil.

Confusing wait methods with other WebDriver methods.

The correct method to wait for a condition is until.

4fill in blank

hard

Fill both blanks to select a date from a calendar widget by clicking the correct day.

Selenium Java

WebElement calendar = driver.findElement(By.className("calendar"));
calendar.findElement(By.[1]("[2]"));

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

BcssSelector

Cid

Dname

Attempts:

💡 Hint

Common Mistakes

Using id or name which may not exist for day elements.

Using cssSelector without the correct selector string.

Use By.xpath with a proper XPath expression to find the day element inside the calendar.

5fill in blank

hard

Fill all three blanks to create a map of dates and their availability status from the date picker.

Selenium Java

Map<String, Boolean> availability = new HashMap<>();
for(WebElement day : driver.findElements(By.className("[1]"))) {
    String date = day.getAttribute("[2]");
    boolean isAvailable = !day.getAttribute("class").contains("[3]");
    availability.put(date, isAvailable);
}

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

Aday-cell

Bdata-date

Cdisabled

Dcalendar-day

Attempts:

💡 Hint

Common Mistakes

Using wrong class names that do not match the date picker structure.

Confusing attribute names for dates or status.

The date cells have class day-cell, the date is stored in attribute data-date, and disabled days have class disabled.

Practice

1. What is the main reason to use a date picker in a web form during testing?

easy

A. To speed up page loading time

B. To allow users to select a date easily and avoid manual input errors

C. To change the website's theme colors

D. To validate user passwords

Solution

1. Step 1: Understand the purpose of a date picker

   A date picker helps users select dates without typing, reducing errors.

2. Step 2: Identify the testing goal

   Testing ensures the date picker works correctly and inputs valid dates.

3. Final Answer:

   To allow users to select a date easily and avoid manual input errors -> Option B

4. Quick Check:

   Date picker purpose = Easy date selection [OK]

Hint: Date pickers help avoid typing mistakes [OK]

Common Mistakes:

• Confusing date picker with unrelated UI elements
• Thinking date picker changes page speed
• Assuming date picker validates passwords

2. Which Selenium Java code snippet correctly clicks a date picker input field using its id 'dateInput'?

easy

A. driver.findElement(By.tagName("dateInput")).click();

B. driver.findElement(By.name("dateInput")).click();

C. driver.findElement(By.className("dateInput")).click();

D. driver.findElement(By.id("dateInput")).click();

Solution

1. Step 1: Identify the locator strategy for id

   Use By.id("dateInput") to find element by its id attribute.

2. Step 2: Use click() method on the found element

   Calling click() simulates user clicking the date picker input.

3. Final Answer:

   driver.findElement(By.id("dateInput")).click(); -> Option D

4. Quick Check:

   Use By.id for id attribute [OK]

Hint: Use By.id for id locators in Selenium [OK]

Common Mistakes:

• Using By.name when id is given
• Using By.className incorrectly
• Using By.tagName with id value

3. Given this Selenium Java code snippet, what will be the output if the date picker input's value is set correctly?

WebElement dateInput = driver.findElement(By.id("dateInput"));
dateInput.click();
dateInput.sendKeys("2024-07-15");
String selectedDate = dateInput.getAttribute("value");
System.out.println(selectedDate);

medium

A. 2024/07/15

B. null

C. 2024-07-15

D. Date picker not found

Solution

1. Step 1: Understand sendKeys sets input value

   sendKeys("2024-07-15") inputs the date string into the field.

2. Step 2: getAttribute("value") retrieves the current input value

   This returns the exact string typed, which is "2024-07-15".

3. Final Answer:

   2024-07-15 -> Option C

4. Quick Check:

   sendKeys sets value, getAttribute reads it [OK]

Hint: sendKeys sets input, getAttribute("value") reads it [OK]

Common Mistakes:

• Expecting formatted date different from input
• Assuming getText() returns input value
• Confusing null with empty string

4. You wrote this Selenium Java code to select a date but the test fails with NoSuchElementException:

driver.findElement(By.xpath("//input[@id='dateInput']")).sendKeys("2024-12-01");

What is the most likely cause and fix?

medium

A. The date picker input is inside an iframe; switch to iframe before accessing it

B. The xpath syntax is incorrect; use By.id instead

C. sendKeys cannot be used on input fields

D. The date format "2024-12-01" is invalid

Solution

1. Step 1: Understand NoSuchElementException means element not found

   This often happens if element is inside an iframe or not visible yet.

2. Step 2: Check if date picker is inside iframe and switch context

   Switching to iframe with driver.switchTo().frame(...) allows access to elements inside it.

3. Final Answer:

   The date picker input is inside an iframe; switch to iframe before accessing it -> Option A

4. Quick Check:

   Switch to iframe to find elements inside [OK]

Hint: Check if element is inside iframe before locating [OK]

Common Mistakes:

• Assuming xpath is always wrong
• Thinking sendKeys can't be used on inputs
• Blaming date format for element not found

5. You want to select a date 10 days from today using Selenium Java on a date picker that only allows clicking days (no typing). Which strategy is best?

hard

A. Calculate the target date, open the date picker, then click the day button matching that date

B. Use sendKeys to type the date string directly into the input field

C. Reload the page and hope the default date is correct

D. Use JavaScript to set the input value without clicking

Solution

1. Step 1: Calculate the date 10 days from today in Java

   Use LocalDate.now().plusDays(10) to get the target date.

2. Step 2: Open the date picker and click the day matching the target date

   Locate the day button by text or attribute and click it to select.

3. Final Answer:

   Calculate the target date, open the date picker, then click the day button matching that date -> Option A

4. Quick Check:

   Click matching day for pickers without typing [OK]

Hint: Click the correct day button after calculating date [OK]

Common Mistakes:

• Trying to type date when input disallows it
• Ignoring date calculation and clicking wrong day
• Using JavaScript to set value without UI interaction
