测试 http://literallycanvas.com/
以 Chrome Driver 为例阐述,通过 Actions 在 Canvas 上绘制一个封闭图形。对于 Canvas 上的操作,推荐 Chrome Driver 或 Firefox Driver
示例:
package com.learningselenium.html5;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
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.interactions.Actions;
public class testHTML5Canvas{
WebDriver driver;
@Before
public void setUp() throws Exception{
System.setProperty("webdriver.chrome.driver", "/Selenium 2/selenium/chromedriver");
driver = new ChromeDriver();
driver.get("http://literallycanvas.com/");
}
@Test
public void testHTML5Canvas() throws Exception{
//元素不存在,有问题 “div.literally.index div.lc-drawing canvas”
WebElement canvas = driver.findElement(By.xpath("//*[@id = "about"]/div[1]/canvas"));
Actions drawing = new Action(driver);
//绘制图形
driver.clickAndHold(canvas).moveByOffset(10,50).moveByOffset(50,10).moveByOffset(-10,-50).moveByOffset(-50,-10).release().perform();
}
@After
public void tearDown() throws Exception{
driver.quit();
}
}
