Page Object

Introduction to PO

https://www.selenium.dev/documentation/en/guidelines_and_recommendations/page_object_models/

Page Object is one of the best design patterns for Selenium automated test project development practices. Page Object is mainly reflected in the encapsulation of interface interaction details , which can make test cases more concerned with business rather than interface details, and improve the readability of test cases sex.

The advantages of the Page Object design pattern are as follows:

• Reduce code duplication;
• Improve the readability of test cases;
• Improve the maintainability of test cases, especially for projects with frequent UI changes;

Notes on using Paget Object:

• The public method represents the functionality provided by Page
• Try not to expose the internal details of the Page
• don't assert
• Methods can return other Page Objects
• Page Objects does not need to represent the entire page, it can be any part
• The same operation, different results should be separated (correct login, wrong login)

Using po is the process of abstracting or modeling the page, which needs to treat the page as an object.

In object-oriented programming languages, the following two points need to be considered for object-oriented programming:

1. The attribute of the object "global variable" == the element of the web page "location method, location value"
2. The behavior of the object "method" == the operation of the element of the web page

Write the page operation base class

package com.zhongxin.pages;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class BasePage {
    private WebDriver driver;

    public BasePage(WebDriver driver) {
        this.driver = driver;
    }

    /**
     * 封装显式等待
     *
     * @param by 元素定位信息
     * @return 元素对象
     */
    public WebElement waitElementBisibility(By by) {
        WebElement element = null;
        try {
            //5秒元素可见显式等待
            WebDriverWait wait = new WebDriverWait(driver, 5);
            element = wait.until(ExpectedConditions.visibilityOfElementLocated(by));
            return element;
        } catch (Exception e) {
            System.out.println("元素定位异常" + e.getMessage());
        }
        return null;
    }
}
