💡 Hint

Common Mistakes

Using className or tagName can select multiple elements, causing unstable tests.

Using name may not be unique, leading to flaky tests.

Using By.id locates the element by its unique ID, which is the most reliable way to find elements.

Complete the code to wait until the element located by CSS selector is visible.

Selenium Java

new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.visibilityOfElementLocated(By.[1](".login-form")));

💡 Hint

Common Mistakes

Using 'id' when the selector is a class selector (starts with a dot).

Using 'name' which does not match CSS selector syntax.

By.cssSelector is used to locate elements using CSS selectors, which can be very precise and reliable.

💡 Hint

Common Mistakes

Using cssSelector with an XPath string causes errors.

Using id or tagName with XPath string is invalid.

By.xpath is the correct method to locate elements using XPath expressions.

4fill in blank

Fill both blanks to create a stable locator that finds a button by its text using XPath.

Selenium Java

WebElement button = driver.findElement(By.[1]("//button[[2]()='Submit']"));

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

💡 Hint

Common Mistakes

Using cssSelector instead of xpath for text matching.

Using className which cannot match element text.

Using By.xpath with text() allows locating a button by its visible text, which is reliable if the text is unique.

5fill in blank

hard

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

Selenium Java

Map<String, String> elementsText = 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'

B"id"

CgetText

D<

💡 Hint

Common Mistakes

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

Using wrong attribute name instead of 'id'.

Using wrong method instead of getText() to get element text.

The filter uses > to select elements with text length greater than 3. The attribute "id" gets the element's ID. The method getText() retrieves the element's visible text.
