SDET Automation Testing Interview Questions & Answers
We will be covering a wide range of topics including QA manual testing, automation testing, Selenium, Java, Jenkins, Cucumber, Maven, and various testing frameworks.
JAVA SELENIUM FRAMEWORK : Abstraction OOP'S Concept in Selenium Framework?
Abstraction can also be used in Selenium Framework to handle web element locators more efficiently.
Web element locators are used to identify and interact with web elements on a web page, such as buttons, text fields, and drop-down menus.
These locators can be defined in several ways, such as by ID, name, class, or XPath.
Abstraction is the methodology of hiding the implementation of internal details and showing the functionality to the users.
Abstraction is a fundamental concept in Object-Oriented Programming (OOP) that allows you to model complex systems by focusing on the essential features and hiding the implementation details from the user. In the context of Selenium Framework, abstraction is used to create a more flexible and maintainable test automation solution.
Here are some areas in Selenium Framework where abstraction can be applied:
1. Page Object Model (POM): POM is a design pattern used in Selenium Framework to represent web pages as objects. In POM, each web page is modeled as a separate class with methods that interact with the web elements on that page. Abstraction can be used to create a hierarchy of web page objects, where common elements and functionalities are abstracted to a higher-level parent class, and specific elements and functionalities are defined in the child classes.
2. Test Data Management: Test data management is a critical aspect of test automation, where data used in the test cases needs to be managed efficiently. Abstraction can be used to define the test data in a separate class, which can be easily accessed and reused in different test cases. Additionally, data abstraction can be used to separate test data from the test logic, making it more maintainable and scalable.
3. Test Reporting: Test reporting is an essential aspect of test automation, where test results need to be reported in a structured and informative manner. Abstraction can be used to define a report format in a separate class, which can be used across different test cases, making the reporting process more consistent and maintainable.
Overall, abstraction is a powerful concept in OOP that can be used to create a more flexible and maintainable test automation solution. By abstracting the common features and functionalities, you can create a reusable codebase that is easier to maintain and extend.
However, directly using these locators in our test code can make it harder to maintain and update our tests. For example, if the ID of an element changes, we would need to update every instance of that locator in our test code.
Abstraction can be used to handle these locators more efficiently. We can define a separate class that contains all the locators for a specific page, and use these locators in our test code instead of the direct By locators.
Here's an example of how abstraction can be used for web element locators:
public class HomePage {
private WebDriver driver;
// Define the locators for the web elements on the page
private By loginButton = By.id("login-button");
private By usernameField = By.name("username");
private By passwordField = By.name("password");
public HomePage(WebDriver driver) {
this.driver = driver;
}
// Define methods that interact with the web elements on the page
public void clickLoginButton() {
driver.findElement(loginButton).click();
}
public void enterUsername(String username) {
driver.findElement(usernameField).sendKeys(username);
}
public void enterPassword(String password) {
driver.findElement(passwordField).sendKeys(password);
}
}
In the above code, we have defined a HomePage class that contains the web element locators for the login button, username field, and password field. We have also defined methods that interact with these web elements, such as clickLoginButton(), enterUsername(), and enterPassword().
By defining the web element locators in a separate class, we can easily update these locators if they change in the future. We can also reuse these locators across different methods in our test code, reducing code duplication and making our tests more maintainable.
