Java + TestNG。 不存在的元素无法执行else语句

Question

    boolean a = browser1.findElement(By.xpath("//*[@id='tsf']/div[2]/div[3]/center/input")).isDisplayed();

    if (a == true)
    {
        extent.log(LogStatus.PASS, "Website launched");
    }
    else
    {
        extent.log(LogStatus.FAIL, "Website no launched");
    }

If the xpath element is present it is successful to log the true statement. But for not present xpath element it will not go into else statement. How can I set to find/verify the exist or non exist element in testng?

Answer 1

Using Assert will send Pass/Fail result in testNG.

WebDriver browser1 = new FirefoxDriver();
        try
        {
            WebElement w = browser1.findElement(By.xpath("//*[@id='tsf']/div[2]/div[3]/center/input"));
            boolean flag = w.isDisplayed();

            if(flag)
            {
                Assert.assertTrue(true, "Website Launched");
            }
            else
            {
                Assert.fail("Website no launched");
            }

        }catch(NoSuchElementException n)
        {
            Assert.fail("Website no launched");
        }

Answer 2

Create function like below code to find element:

boolean a = isElementPresent(By.xpath("//*[@id='tsf']/div[2]/div[3]/center/input"));

public boolean isElementPresent(String element){
    try{
        browser1.findElement(By.xpath(element)).isDisplayed();
        return true;
       }
       catch(Exception ex){
           return false;
       }

}
