How to set default download location property for chrome using selenium wedriver in java?

Question

I want to set automatic download in specified download location using webdriver. I tried following code which is not working for chrome:

        ChromeOptions options = new ChromeOptions();
        options.addArguments("download.default_directory", downloadPath);
        this.driver = new ChromeDriver(options);

Can you please correct me where i am wrong?

Answer 1

Here is a more current answer for people like me who are searching for this and kept coming back to a question asked 3 years ago. This was answered by Chromium support here in Comment 8: in April '15.

Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("download.default_directory", "C:\\New_Download");

DesiredCapabilities caps = DesiredCapabilities.chrome();

ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", prefs);
options.addArguments("--disable-extensions");
caps.setCapability(ChromeOptions.CAPABILITY, options);

WebDriver driver = new ChromeDriver(caps);
driver.get("http://www.google.com");

I have tested it locally and it works. You may need to add the following option argument to disable extensions like I did, which is, options.addArguments("--disable-extensions");

I'm not sure that you'll be able to perform download setting only chromeOption due to the following reason:

ChromeOptions class does contain implementation of download path argument.

But I would recommend you to use alternative approach, although it looks more complicated:

}

appropriate examples of the code above usage:

@Test
public void downloadAFile() throws Exception {
    FileDownloader downloadTestFile = new FileDownloader(driver);
    driver.get("http://www.localhost.com/downloadTest.html");
    WebElement downloadLink = driver.findElement(By.id("fileToDownload"));
    String downloadedFileAbsoluteLocation = downloadTestFile.downloadFile(downloadLink);

    assertThat(new File(downloadedFileAbsoluteLocation).exists(), is(equalTo(true)));
    assertThat(downloadTestFile.getHTTPStatusOfLastDownloadAttempt(), is(equalTo(200)));
}

@Test
public void downloadAnImage() throws Exception {
    FileDownloader downloadTestFile = new FileDownloader(driver);
    driver.get("http://www.localhost.com//downloadTest.html");
    WebElement image = driver.findElement(By.id("ebselenImage"));
    String downloadedImageAbsoluteLocation = downloadTestFile.downloadImage(image);

    assertThat(new File(downloadedImageAbsoluteLocation).exists(), is(equalTo(true)));
    assertThat(downloadTestFile.getHTTPStatusOfLastDownloadAttempt(), is(equalTo(200)));
}
