Cypress is a front-end testing tool that allows developers to write tests in JavaScript. The tool is unique in that it runs tests directly in the browser, making it possible to test how users would interact with an application. Cypress is also notable for its support of modern web technologies, such as Angular and React. In this article, we’ll explore the Cypress E2E web automation tool and the Page Object Model pattern.
ThePage Object Model (POM) is a design pattern that can be used in software development to organize code related to a specific page or component within an application. The purpose of the Page Object Model is to make code more maintainable and reusable. When used correctly, the Page Object Model can also make tests more readable and easier to write.
In its simplest form, the Page Object Model consists of two parts:
• A page class: This is a class that represents a page or component within an application. The page class contains all the information and logic related to that page or component.
• A page object: This is an object that represents an instance of a page class. A page object can be used to access the information and methods defined in a page class.
The Page Object Model can be implemented using any programming language, but it is most commonly used with object-oriented languages such as Java or C#. The example below shows how the Page Object Model can be used in Java to represent a login page:
public class LoginPage {
private WebDriver driver;
public LoginPage(WebDriver driver) {
this.driver = driver;
}
public void enterUsername(String username) {
// Code to enter username
}
public void enterPassword(String password) {
// Code to enter password } public void clickLogin() { // Code to click login button } }
LoginPage loginPage = new LoginPage(driver); loginPage.enterUsername(“testuser”); loginPage.enterPassword(“secretpass”); loginpageLogin();
As you can see from the example above, the Page Object Model makes it easy to reuse code related to a specific page or component within an application. In our example, the methods defined in the LoginPage class can be reused whenever we need to login to an application. Furthermore, by encapsulating all code related to a specific page or component into one place, the PageObject Model makes code more maintainable and less error-prone. There are many benefits to using the Page Object Model pattern, but there are also some drawbacks that should be considered before deciding whether or not to use it in your project
