package com.thetestingacademy.driver;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.edge.EdgeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class DriverManager {
private static WebDriver driver;
public static WebDriver getDriver() {
return driver;

}
The simplest POM pattern where each page class owns its locators and uses driver.findElement() directly.
package com.thetestingacademy.pages.pageObjectModel.normal_POM.normal_POM.vwo;
import com.thetestingacademy.utils.PropertiesReader;
import com.thetestingacademy.utils.WaitHelpers;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
public class LoginPage {
private WebDriver driver;
// Locators
private By username = By.id("login-username");
private By password = By.id("login-password");
private By signButton = By.id("js-login-btn");
private By error_message = By.cssSelector("[data-qa='error-text']");
public LoginPage(WebDriver driver) {
this.driver = driver;
}
public String loginToVWOLoginInvalidCreds(String user, String pwd) {
driver.get(PropertiesReader.readKey("url"));
driver.findElement(username).sendKeys(user);
driver.findElement(password).sendKeys(pwd);
driver.findElement(signButton).click();
WaitHelpers.checkVisibility(driver, error_message, 3);
return driver.findElement(error_message).getText();
}
public void loginToVWOLoginValidCreds(String user, String pwd) {
driver.get(PropertiesReader.readKey("url"));
driver.findElement(username).sendKeys(user);
driver.findElement(password).sendKeys(pwd);
driver.findElement(signButton).click();
}
}
Extends CommonToAllPage to reuse common actions like clickElement(), enterInput(), getText(). Eliminates repeated driver.findElement() calls.
package com.thetestingacademy.pages.pageObjectModel.normal_POM.imporved_POM.vwo;
import com.thetestingacademy.base.CommonToAllPage;
import com.thetestingacademy.utils.WaitHelpers;
import org.openqa.selenium.By;
public class LoginPage extends CommonToAllPage {
private By username = By.id("login-username");

openVWOUrl();
enterInput(username, user);
enterInput(password, pwd);
clickElement(signButton);

return getText(error_message);
}
}
Uses Selenium's @FindBy annotations for declarative element location. Elements are automatically initialized via PageFactory.initElements().

private WebElement error_message;
public LoginPage_PF(WebDriver driver) {
PageFactory.initElements(driver, this);
}
public String loginToVWOInvalidCreds() {
openVWOUrl();

enterInput(password, PropertiesReader.readKey("invalid_password"));

data.properties for configuration and TestData.xlsx for parameterized test data. Never hardcode URLs, credentials, or expected values.WebDriverWait with ExpectedConditions over implicit waits.RetryAnalyzer with a max retry count of 1-2. Apply globally via RetryListener in TestNG XML.ScreenshotListener to automatically capture and attach screenshots to Allure reports on every test failure.Assert.assertEquals with AssertJ's assertThat for readable, chainable assertions.Thread.sleep() for synchronization -- Always use explicit waits with conditions. Sleep causes brittle, slow tests.driver.findElement() in test classes -- Always go through page objects. Tests should only call page object methods.DriverManager.down() in @AfterMethod to prevent zombie browser processes.ScreenshotListener and attach evidence to reports for debugging.
