Objective : I wanna "split" the extracted cookie from ";" and save the cookie value in a iterative manner for each user in a csv file, column wise, for my Apache JMeter code in Selenium Webdriver Sampler in java language. I am using a CSV Dataset config to fetch the username & password and would like to save the cookie value in a separate column.

I am unable to spilt the cookie and save using the following code snippet.

My code Snippet

import org.openqa.selenium.*;
import org.openqa.selenium.support.ui.*;
import org.junit.Assert;
import org.openqa.selenium.chrome.ChromeDriver;
import java.time.Duration;
import java.io.*;
import java.util.Arrays;
import java.io.FileWriter;
import java.util.List;
import java.io.Writer;
import java.lang.String;

// Login 
String title = driver.getTitle();
System.out.println(title);
Assert.assertEquals("Sign in to your account", title);
WebElement username = new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.xpath(".//input[@type='email']")));
driver.findElement(By.xpath(".//input[@type='email']")).click();
driver.findElement(By.xpath(".//input[@type='email']")).sendKeys(new String[] {WDS.vars.get("username")});
driver.findElement(By.xpath(".//input[@type='submit']")).click();
WebElement username = new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.xpath(".//input[@type='password']")));
driver.findElement(By.xpath(".//input[@type='password']")).click();
driver.findElement(By.xpath(".//input[@type='password']")).sendKeys(new String[] {WDS.vars.get("password")});
driver.findElement(By.xpath(".//input[@type='submit']")).click();
Thread.sleep(3000L);
driver.findElement(By.xpath(".//input[@type='button']")).click();
Thread.sleep(3000L);

// Generating the cookie
String rawValue = driver.manage().getCookieNamed(".sampleCookie");
System.out.println(rawValue);
WDS.log.info(WDS.vars.get("rawValue"));
System.out.println("Login Successful");
WDS.log.info("Login Successful");

I am able to use the above code snippet to generate the cookie, but unable to print in JMeter Log console using WDS.log.info(WDS.vars.get("rawValue"));

I am unable to split the cookie via below mentioned code.

//Splitting the cookie 

//Split cookie string from semicolon
String[] cookie = rawValue.split(";");

I am unable to save the split cookie value or the raw cookie Value in that case via below mentioned code.

//Write the cookie value to a csv file

FileWriter fstream = new FileWriter("C:\\Users\\Scripts\\TestData\\Cookie.csv",true);
BufferedWriter out = new BufferedWriter(fstream);
out.write(WDS.vars.get("rawValue"));
out.write(System.getProperty("line.separator"));
out.close();
fstream.close();

I have imported the required classes and have tried executing this code snippets individually with the login code, did'nt worked out. I would really appreciate if anyone can aid me with the solutions.

raw cookie Value = .sampleCookie=eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1laWRlbnRpZmllciI6IjEiLCJoyA;

split cookie value = eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1laWRlbnRpZmllciI6IjEiLCJoyA

CodePudding user response：

driver.manage().getCookieNamed function gives you an instance of org.openqa.selenium.Cookie which doesn't have split() function

If you want to continue with this approach you need to cast it to String first:

String[] cookie = rawValue.toString().split(";");

Alternatively you can use Cookie class functions instead of "splitting", i.e.

• rawValue.getName()
• rawValue.getValue()
• rawValue.getDomain()
• rawValue.getExpiry()
• rawValue.isSecure()
• rawValue.isHttpOnly()

The same is for printing it to the log file, you cannot put a Cookie object there, you need to change it to be a String:

WDS.log.info(rawValue.toString());

Also your approach of writing the variables into the file won't work if you intend to run your script with 2 or more users, the target file will have corrupt data due to race conditions so consider switching to Sample Variables and Flexible File Writer instead.
