WhatsApp Message using Selenium Java

Prerequisites :

• Create a new folder on any driver except C Drive. The folder name should be “Chrome_Test_Profile”.
• Set the chrome application path to an environment variable. Follow the below steps to set environment path in windows: 
• In Search, search this: System (Control Panel) 
• Click the Advanced system settings link. 
• Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New. 
• In the Edit System Variable (or New System Variable) window, append the path. (E.g. C:\Program Files (x86)\Google\Chrome\Application). 

Once you are done with all the above, setup follow the below steps:

1. Open Chrome In debug mode using the following command.
Command: chrome.exe -remote-debugging-port=9014 --user-data-dir="E:\Selenium Scripts\Chrome_Test_Profile” (This command opens the window in debug mode).



You can use any port, here I am using 9014.
By executing the above command it will create a new profile for the chrome. It will not affect the original profile of chrome.

2. Now open https://web.whatsapp.com and login with your account in chrome. Which is already running in debug mode.



3. Now Open Eclipse and create a new java project.

• File > New > Java Project
• Write Project Name (e.g. WhatsappMsgSender) and click on next.
• Now go to library > Add external Jars ( Add All selenium Required jar files )Selenium standalone server and other Required jar files you can download from this link: https://www.seleniumhq.org/download/
• Click on finish.

4. Now create a new package as below :

• Right-click on project > new > package
• Write a package name (e.g. whatsappmsg). 
• Click on finish 

5. Now create a new class in the above-created package.

• Right-click on project > new > Class
• Write class name (e.g. SendMsg).
• Click on finish

6. Create one main method in the above-created class and add following code for executing script in chrome which is already open in debugging mode in step 2.

System.setProperty("webdriver.chrome.driver", "E:\\Selenium Scripts\\libs\\chromedriver.exe"); 

ChromeOptions options = new ChromeOptions();

options.setExperimentalOption("debuggerAddress","localhost:9014");

WebDriver driver= new ChromeDriver(options);

driver.manage().timeouts().implicitlyWait(60,TimeUnit.SECONDS);

Above code will interact with the already open chrome browser.

7. Write Following code for clicking on new message
driver.findElement(By.cssSelector("#side > header > div.sbcXq > div > span > div:nth-child(2)")).click();
Thread.sleep(200);

8. To read contact number and message, Create a comma Separated CSV File in below format.
CSV Format:

Name 1, Message 1,
Name 2, Message 2




10. Write the following code to read a contact number and message from a CSV file.
try (BufferedReader br = new BufferedReader(new FileReader(csvFile)))
{

                 while ((line = br.readLine()) != null)
                       {

                           driver.findElement(By.cssSelector("#side > header > div.sbcXq > div > span > div:nth-child(2)")).click();
                            ContactInfo = line.split(cvsSplitBy);
                             int i = 0;
                             int j = 1;
                          driver.findElement(By.cssSelector("#app > div > div > div._37f_5 >                    div._3HZor._3kF8H > span > div > span > div > div:nth-child(2) > div > label > input")).sendKeys(ContactInfo[i]);
                       Thread.sleep(2000);
                       Actions action = new Actions(driver);
                       action.sendKeys(Keys.ENTER).build().perform();
                      driver.findElement(By.cssSelector("#main > footer > div._2i7Ej.copyable-area > div._13mgZ > div > div._3u328.copyable-text.selectable-text")).sendKeys(ContactInfo[j]);
                      Thread.sleep(2000);
                      action.sendKeys(Keys.ENTER).build().perform();
                     Thread.sleep(2000); 

                      i++;

                      j++;
                 }
}
catch (IOException e)
{
       e.printStackTrace();
}
