What do I need to do if dropdown takes more time to populate 1st element from dropdown list?

Question

What do I need to do if drop down take time to populate 1st element from drop down list?

Select Cdropdown = new Select(driver.findElement(By.xpath("//select[@id='ClientId']")));
        Cdropdown.selectByVisibleText("centralpen-ak-01");

Thread.sleep(3000);

Select Edropdown = new Select(driver.findElement(By.xpath("//select[@id='EnvironmentId']")));
            Edropdown.selectByValue("1121");

For loading the drop down it should take the time I have used- Thread.sleep(3000); but still the element is not found. What should I do in such a case?

Answer 1

Do you think that time is the problem here?

If so try to increase the time you are providing in Thread.sleep(); and see it that works out for you.

If its not the time, then did you try to find out what the problem is? Are you getting any error?

Answer 2

adding Thread.sleep(3000) is not a good way to handle synchronization, rather use implicit wait.

driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

Implicit wait allows your browser to wait until element is visible or until time set by you, whichever is earlier.

1:

Select Cdropdown = new Select(driver.findElement(By.xpath("//select[@id='ClientId']")));
Cdropdown.selectByVisibleText("centralpen-ak-01");

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Select Edropdown = new Select(driver.findElement(By.xpath("//select[@id='EnvironmentId']")));
                    Edropdown.selectByIndex(0);
//check your index, starting from 0 which item you have to select & add corresponding index of that.  

OR
2:
You may try with same method-selectByVisibleText as like 1st dropdown

3: Otherwise You may try with explicitly wait-

 //Selecting value from 2nd drop down using visible text

    Select mydrpdwn = new Select(driver.findElement(By.id("EnvironmentId")));
    mydrpdwn.selectByVisibleText("add element in dropdown");

    WebDriverWait wait = new WebDriverWait(driver, 15);
    wait.until(ExpectedConditions.elementToBeClickable(By.id("EnvironmentId")));

Answer 4

try following code:

WebDriverWait wait;
wait = new WebDriverWait(driver, Duration.ofSeconds(15));
wait.until(ExpectedConditions.visibilityOf(WebElement));
