How To Check Wether File Is Downloaded In Selenium

In this tutorial, nosotros volition learn How to deal with file uploads and downloads.

Uploading Files

For this section, we volition use http://demo.guru99.com/exam/upload/ every bit our test application. This site easily allows whatsoever visitor to upload files without requiring them to sign upwards.

Uploading files in WebDriver is done by simply using the sendKeys() method on the file-select input field to enter the path to the file to exist uploaded.

Allow's say we wish to upload the file "C:\newhtml.html". Our WebDriver code should be like the 1 shown below.

packet newproject; import org.openqa.selenium.*; import org.openqa.selenium.firefox.FirefoxDriver; public class PG9 {     public static void principal(String[] args) {         System.setProperty("webdriver.gecko.driver","C:\\geckodriver.exe");         String baseUrl = "http://demo.guru99.com/test/upload/";         WebDriver driver = new FirefoxDriver();          driver.become(baseUrl);         WebElement uploadElement = driver.findElement(By.id("uploadfile_0"));          // enter the file path onto the file-selection input field         uploadElement.sendKeys("C:\\newhtml.html");          // check the "I accept the terms of service" check box         driver.findElement(Past.id("terms")).click();          // click the "UploadFile" button         driver.findElement(By.name("send")).click();         } }

Subsequently running this script, y'all should be able to upload the file successfully and you should get a message similar to this.

Call back following two things when uploading files in WebDriver

In that location is no need to simulate the clicking of the "Browse" button. WebDriver automatically enters the file path onto the file-selection text box of the <input type="file"> element
When setting the file path in your Java IDE, use the proper escape character for the back-slash.

Downloading Files

WebDriver has no capability to access the Download dialog boxes presented by browsers when you click on a download link or button. However, we can bypass these dialog boxes using a separate program called "wget".

What is Wget?

Wget is a small and like shooting fish in a barrel-to-utilise command-line program used to automate downloads. Basically, we will admission Wget from our WebDriver script to perform the download process.

Setting upwards Wget

Footstep ane: In your C Drive, create a new binder and name it equally "Wget".

Download wget.exe from here and Identify it in the Wget folder you lot created from the footstep above.

Step two: Open Run by pressing windows central + "R" ; type in "cmd & click ok

Type in the control "cd /" to motion to the root directory

Step 3: Blazon in the command to check whether the given setup is working

cmd /c C:\\Wget\\wget.exe -P C: --no-check-certificate http://demo.guru99.com/selenium/msgr11us.exe

There seems to be an issue writing into C drive.

Step 4: You demand to debug the wget errors in command line before you lot execute the lawmaking using Selenium Webdriver. These errors will persist in Eclipse and the fault messages will not be as informative. Best to showtime get wget working using command line. If information technology works in command line information technology will definitely piece of work in Eclipse.

In our example, as show in step 3, there is a trouble writing into C drive. Allow'southward change the download location to D drive and bank check results.

cmd /c C:\\Wget\\wget.exe -P D: --no-check-certificate http://demo.guru99.com/selenium/msgr11us.exe

Messenger was downloaded successfully.

Before yous proceed further don't forget to delete the downloaded file

Using WebDriver and Wget

In the following case, we will use WebDriver and wget to download a popular chat software called Yahoo Messenger. Our base URL shall be http://demo.guru99.com/test/yahoo.html.

Step 1

Import the "java.io.IOException" package because we volition have to take hold of an IOException later in Step 4.

Pace ii

Use getAttribute() to obtain the "href" value of the download link and save information technology as a String variable. In this case, we named the variable as "sourceLocation".

Pace iii

Ready-up the syntax for wget using the post-obit command.

Pace 4

Initiate the download process by calling wget from our WebDriver code.

To sum information technology all up, your WebDriver lawmaking could look like the i shown below.

package newproject; import java.io.IOException;  import org.openqa.selenium.*; import org.openqa.selenium.firefox.FirefoxDriver; public course PG8 {     public static void main(String[] args) {                  System.setProperty("webdriver.gecko.driver","C:\\geckodriver.exe");                 String baseUrl = "http://demo.guru99.com/test/yahoo.html";         WebDriver driver = new FirefoxDriver();          driver.get(baseUrl);         WebElement downloadButton = driver.findElement(Past         .id("messenger-download"));         Cord sourceLocation = downloadButton.getAttribute("href");         String wget_command = "cmd /c C:\\Wget\\wget.exe -P D: --no-cheque-certificate " + sourceLocation;          try {         Process exec = Runtime.getRuntime().exec(wget_command);         int exitVal = exec.waitFor();         Arrangement.out.println("Exit value: " + exitVal);         } catch (InterruptedException | IOException ex) {         Organization.out.println(ex.toString());         }         driver.close();         }          }

Later executing this code, bank check your D bulldoze and verify that the Yahoo Messenger installer was successfully downloaded at that place.

Summary

Uploading files in WebDriver is washed by simply using the sendKeys() method on the file-select input field to enter the path to the file to be uploaded.
WebDriver cannot automate downloading of files on its own.
The easiest mode to download files using WebDriver is to use Wget.
