How to Download File using WebDriver

By
When we download file from a web page, it asks for confirmation to download along with the download location. For automating this download file process, we have to set some preferences based on the browser used.
In this article, we will see file download for Firefox and Chrome separately.

Download File using FirefoxDriver

For firefox, we have to set the below firefox profile preferences.
  • browser.download.dir – The download directory
  • browser.download.folderList – It has to be set to 2 to make firefox use custom download directory (the above given download directory). If value is 0, it downloads the file to user’s desktop and if its 1, it uses the default Downloads folder.
  • browser.download.manager.showWhenStarting – Whether to show the download manager when starting download
  • browser.helperApps.neverAsk.saveToDisk – Never ask for saving to disk for the given file types.
Using the above preferences, we can create the profile and initialize the FirefoxDriver.

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.dir", "D:\\Custom\\Download\\Directory");
profile.setPreference("browser.download.folderList", 2);
// File type of the downloaded file
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv");
profile.setPreference( "browser.download.manager.showWhenStarting", false );
profile.setPreference( "pdfjs.disabled", true );
// Initialize webdriver using the profile
WebDriver driver = new FirefoxDriver(profile);

Download File using Chrome

The method is similar for chromedriver in which we set the ExperimentalOptions preferences in ChromeOptions as shown below.
Preferences Set
  • download.default_directory – The download directory
  • profile.default_content_settings.popups – To disallow popups

ChromeOptions options = new ChromeOptions();
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("profile.default_content_settings.popups", 0);
prefs.put("download.default_directory", "D:\\Downloads\\Directory");
options.setExperimentalOption("prefs", prefs);
WebDriver driver = new ChromeDriver(options);
We will be covering How to Import Files using WebDriver in a future post.

Testing Types

By
         Installation testing Main article: Installation testing An installation test assures that the system is installed correctly and working at actual customer's hardware. Compatibility testing Main article: Compatibility testing A common cause of software failure (real or perceived) is a lack of its compatibility with other application software, operating systems (or operating system versions, old or new), or target environments that differ greatly from the original (such as a terminal or GUI application intended to be run on the desktop now being required to become a web application, which must render in a web browser). For example, in the case of a lack of backward compatibility, this can occur because the programmers develop and test software only on the latest version of the target environment, which not all users may be running. This results in the unintended cons...

Clickjacking

By
Clickjacking Clickjacking  ( User Interface redress attack ,  UI redress attack ,  UI redressing ) is a  malicious technique  of tricking a  Web   user  into clicking on something different from what the user perceives they are clicking on, thus potentially revealing  confidential  information or taking control of their computer while clicking on seemingly innocuous  web pages . It is a  browser security  issue that is a  vulnerability  across a variety of  browsers  and  platforms . A clickjack takes the form of embedded  code  or a script that can execute without the user's knowledge, such as clicking on a  button  that appears to perform another function. [5]  The term "clickjacking" was coined by Jeremiah Grossman and Robert Hansen in 2008. [ citation needed ]  Clickjacking can be understood as an instance of the  confused deputy problem . [6] ...
