💡 Hint

Complete the code to wait until the file is downloaded by checking the file existence.

Cfile.isHidden()

Dfile.exists()

💡 Hint

Common Mistakes

Using isDirectory() which checks if the path is a folder.

Using canRead() or isHidden() which do not confirm file presence.

To confirm the file is downloaded, we wait until the file exists in the download folder.

Fix the error in the code that tries to delete the downloaded file after test completion.

Selenium Java

File downloadedFile = new File("C:/Downloads/report.pdf");
if ([1]) {
    downloadedFile.delete();
}

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

AdownloadedFile.isFile()

BdownloadedFile.exists()

CdownloadedFile.canWrite()

DdownloadedFile.isDirectory()

💡 Hint

Common Mistakes

Using isDirectory() which is false for files.

Using canWrite() which checks permissions but not existence.

Before deleting, check if the file exists using exists() method to avoid errors.

Fill both blanks to configure Firefox profile to auto-download PDF files without prompt.

Selenium Java

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.folderList", [1]);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", [2]);

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

A2

B"application/pdf"

C1

D"text/plain"

💡 Hint

Common Mistakes

Using folderList 1 which is default downloads folder.

Setting wrong MIME type that does not match PDF files.

Setting folderList to 2 uses a custom folder, and neverAsk.saveToDisk to "application/pdf" disables the save prompt for PDFs.

5fill in blank

hard

Fill all three blanks to create a test that clicks a download link, waits for the file, and asserts its existence.

Selenium Java

driver.findElement(By.id([1])).click();
File file = new File([2]);
new WebDriverWait(driver, Duration.ofSeconds(20)).until(d -> file.[3]);

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

A"downloadLink"

B"C:/Downloads/testfile.zip"

Cexists()

DisFile()

Attempts:

💡 Hint

Common Mistakes

Using wrong element id or file path string.

Waiting on isFile() which may be false if file is not fully ready.

Click the element with id "downloadLink", check the file path, and wait until the file exists.
