Thread.sleep vs proper waits in Selenium Java - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to pause the test execution for 3 seconds using Thread.sleep.

Selenium Java

Thread.sleep([1]);

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

C3000

D30

💡 Hint

Common Mistakes

Using 3 instead of 3000 causes the sleep to be too short.

Using 30 or 300 is not the correct duration for 3 seconds.

Thread.sleep expects time in milliseconds. 3000 ms equals 3 seconds.

2fill in blank

medium

Complete the code to create an explicit wait that waits up to 10 seconds.

Selenium Java

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds([1]));

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

A10

B20

D15

Attempts:

💡 Hint

Common Mistakes

Using 5 or 15 seconds when the requirement is 10 seconds.

Confusing milliseconds with seconds.

The explicit wait is set to 10 seconds using Duration.ofSeconds(10).

3fill in blank

hard

Fix the error in the code to wait until the element with id 'submit' is clickable.

Selenium Java

wait.until(ExpectedConditions.[1](By.id("submit")));

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

AalertIsPresent

BvisibilityOfElementLocated

CpresenceOfElementLocated

DelementToBeClickable

Attempts:

3 left

💡 Hint

Common Mistakes

Using visibilityOfElementLocated waits only for visibility, not clickability.

Using presenceOfElementLocated waits only for presence in DOM.

To wait until an element is clickable, use ExpectedConditions.elementToBeClickable.

4fill in blank

hard

Fill both blanks to create a fluent wait that polls every 2 seconds and ignores NoSuchElementException.

Selenium Java

Wait<WebDriver> wait = new FluentWait<>(driver)
    .withTimeout(Duration.ofSeconds([1]))
    .pollingEvery(Duration.ofSeconds([2]))
    .ignoring(NoSuchElementException.class);

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

💡 Hint

Common Mistakes

Swapping timeout and polling interval values.

Using too short or too long polling intervals.

The fluent wait waits up to 30 seconds and polls every 2 seconds, ignoring NoSuchElementException.

5fill in blank

hard

Fill all three blanks to create a stream collector that maps element IDs to their text if text length is greater than 3.

Selenium Java

Map<String, String> texts = elements.stream()
    .filter(e -> e.getText().length() [1] 3)
    .collect(Collectors.toMap(e -> e.getAttribute([2]), e -> e.[3]()));

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

A>

B"id"

CgetText

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' instead of '>' in the filter.

Using wrong attribute name instead of 'id'.

Calling wrong method instead of getText().

The filter checks if text length is greater than 3, keys are element IDs, and values are element texts.
