Can anyone please demonstrate to me how assertTrue or assertFalse methods work in Selenium

Question

I am new to Selenium and trying to understand the concept of Assertions. So can anyone explain how assertTrue() or assertFalse() methods work for any web element?

Answer 1

Hey Priyank, to understand how assertFalse() or assertTrue() works, please refer to the following code snippet:

package co.edureka.selenium.assertions;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;

public class AssertTrueFalse {

 public static void main(String[] args) {

  System.setProperty("webdriver.chrome.driver","C:\\\\Users\\\\Abha_Rathour\\\\Downloads\\\\ExtractedFiles\\\\chromedriver_win32\\\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.navigate().to("https://www.spicejet.com/");
        Assert.assertFalse(driver.findElement(By.cssSelector("input[id*='SeniorCitizenDiscount']")).isSelected());
        System.out.println(driver.findElement(By.cssSelector("input[id*='SeniorCitizenDiscount']")).isSelected());
}

}

Here, assertFalse() will check the isSelected() methods output and if the output will be False, then only it will pass the test.
