How can I implement the “wait until the element is visible” of selenium?
I am currently engaged in a particular task that is related to automating a web-based application by using selenium and Python programming language. When I am trying to log in, the application sometimes displays a loading spinner before the login button becomes visible. Explain to me how can I use the “wait until the element is visible” feature of Selenium for handling this effectively.
In the context of selenium, here are the steps given of how you can handle this situation:-
Import necessary nodules
You should import the required module from Selenium and Python.
Initialize WebDriver
Now try to initialize the WebDriver Instance for your preferred browser.
Navigate to the login page
Now you can try to log in to the page of the web-based application.
Enter the username and password
Now enter the user name and password in the input fields.
Wait until the login button is visible
You can use the “WebDriverWait” to wait until the login button becomes visible on the page.
Here are the steps given in the form of coding:-
From selenium import webdriver
From selenium.webdriver.common.by import By
From selenium.webdriver.support.ui import WebDriverWait
From selenium.webdriver.support import expected_conditions as EC
# Initialize WebDriver (assuming Chrome for this example)
Driver = webdriver.Chrome(executable_path=’path/to/chromedriver’)
Try:
# Navigate to the login page
Driver.get(‘https://example.com/login’)
# Enter username and password
Username_input = driver.find_element(By.ID, ‘username’)
Password_input = driver.find_element(By.ID, ‘password’)
Username_input.send_keys(‘your_username’)
Password_input.send_keys(‘your_password’)
# Wait until login button is visible
Login_button = WebDriverWait(driver, 10).until(
EC.visibility_of_element_located((By.ID, ‘loginButton’))
)
# Click on the login button
Login_button.click()
# Perform additional actions after successful login
# For example, navigate to a specific page or perform verification
Finally:
# Close the WebDriver
Driver.quit()
Here is the same explanation given in java programming language:-
Import org.openqa.selenium.By;
Import org.openqa.selenium.WebDriver;
Import org.openqa.selenium.WebElement;
Import org.openqa.selenium.chrome.ChromeDriver;
Import org.openqa.selenium.support.ui.ExpectedConditions;
Import org.openqa.selenium.support.ui.WebDriverWait;
Public class LoginTest {
Public static void main(String[] args) {
// Set the path to the chromedriver executable
System.setProperty(“webdriver.chrome.driver”, “path/to/chromedriver”);
// Initialize WebDriver (assuming Chrome for this example)
WebDriver driver = new ChromeDriver();
Try {
// Navigate to the login page
Driver.get(https://example.com/login);
// Enter username and password
WebElement usernameInput = driver.findElement(By.id(“username”));
WebElement passwordInput = driver.findElement(By.id(“password”));
usernameInput.sendKeys(“your_username”);
passwordInput.sendKeys(“your_password”);
// Wait until login button is visible
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement loginButton = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id(“loginButton”)));
// Click on the login button
loginButton.click();
// Perform additional actions after successful login
// For example, navigate to a specific page or perform verification
} finally {
// Close the WebDriver
Driver.quit();
}
}
}
