selenium学习笔记1 、webdriver 与 selenium RC2、css选择器By.cssSelector(#f_modify_box div.hd a.cls) 实际如下3、xpath选择器id为userBtn 下的 a下的img selenium.isElementPresent(id(userBtn)/x:a/x:img)By.xpath(/liid=userBtn/a/img)4、点击链接，使用driver.getTitle()来验证6、IE下出现了ElementNotFoundException ，但FF运行正常网上查了半天，都说是IE的保护模式，但是貌似只有vista系统，在IE选项-安全里才有那个选项。重装IE7，问题得到解决。7、火狐出现什么问题呢？driver.get()不能通过，要加上才能够正常运行8、webdriver 如何处理ajax案例：我评论了一条信息，但是页面上显示的是ajax处理的，我要判断页面上是否新增了这条评论。直接判断确拉错了信息（因为AJAX反应没那么快）。所以采用以下写法，5秒之内判断是否能够成功返回正确值，如果可以择判断运行正确。boolean result=new WebDriverWait(driver, 5).until (new ExpectedCondition() public Boolean apply(WebDriver driver) boolean result = false; try List elements=driver.findElements(By.xpath(id(content_li)/li/p); if(elements.size()0)Assert.fail(评论失败,没有增加评论); WebElement ele=(WebElement) elements.get(0); System.out.println(text:+ele.getText(); return ele.getText().contains(s); catch(Exception e) System.out.println(error); return result; ); if(result)Assert.assertTrue(true);else Assert.assertTrue(false);Wait wait = new WebDriverWait(driver, 30);WebElement element= wait.until(visibilityOfElementLocated(By.id(some_id);Where “visibilityOfElementLocated” is implemented as:public ExpectedCondition visibilityOfElementLocated(final By locator) return new ExpectedCondition() public WebElement apply(WebDriver driver) WebElement toReturn = driver.findElement(locator); if (toReturn.isDisplayed() return toReturn; return null; ;9、该element is not visible在页面上肉眼确实TEXTAREA可见，但是运行click函数的时候，抛出异常。于是写了一个循环 一直判断是否可见，经观察，是由于此控件加载未完成。于是等待此控件加载完成才，click。WebDriverWait wait = new WebDriverWait(driver,10);wait.until(ExpectedConditions.elementToBeClickable(By.xpath( ); while(true) if(ele.isDisplayed()break; for(int second=1;second+) if(second60)Assert.fail(超时了); if(text.equals() mouseMenu.click(ele); mouseMenu.perform(); Thread.sleep(1000); System.out.println(n); if(i=3) text=driver.findElement(By.xpath(id(ui-dlg-linkShare)/div1/h2).getText(); else text=driver.findElement(By.xpath(id(ui-dlg-emailShare)/div1/h2).getText(); n+; else break; 10、IE自动保存表单，FF不能，要读取profileIE-选项-内容-保存表单11、有关xpath取值不正确用FF插件弄的是By.xpath(/html/body/div3/div3/div/a);用GOOGLE插件xpathOnClick 这个就能找到elementBy.xpath(/html/body/divcontains(concat( , class, ), wrap )/div3/divcontains(concat( , class, ), dt_sidbox )/a);12、一个神奇的问题之前用JUNIT做测试，引用了他的包，后来改成了testng，在做suite的时候，发现运行不了。解决结果：删除junit包。使用ant build.xml生成的报告也产生了影响。13、chrome最大化DesiredCapabilities capabilities = DesiredCapabilities.chrome();capabilities.setCapability(chrome.switches, Arrays.asList(-start-maximized);WebDriver driver = new ChromeDriver(capabilities);14、增加FF插件File file = new File(.resfirebug-1.9.1-fx.xpi); FirefoxProfile firefoxProfile = new FirefoxProfile(); try firefoxProfile.addExtension(file); catch (IOException e) / TODO Auto-generated catch block e.printStackTrace(); firefoxProfile.setPreference(extensions.firebug.currentVersion,1.9.1);15、webdriver代替TextIsPresent的方法 public boolean isContentAppeared(WebDriver driver,String content) boolean status = false; try driver.findElement(By.xpath(/*contains(., + content + ); System.out.println(content + is appeard!); status = true; catch (NoSuchElementException e) status = false; System.out.println( + content + doesnt exist!); return status; 16、自定义tablepublic class Table private String locator; private WebDriver driver; public Table(WebDriver d, String locator) this.driver = d; this.locator = locator; public String getCellText(int row, int col) String xpath = locator + /tr + row +/td + col + ; WebElement cell = driver.findElement(By.xpath(xpath); return cell.getText(); 17、webdriver常用操作/xiecj_2006/article/details/786903318、截图package test;import java.io.File;import java.io.IOException;import java.text.SimpleDateFormat;import java.util.Date;import mons.io.FileUtils;import org.openqa.selenium.OutputType;import org.openqa.selenium.TakesScreenshot;import org.openqa.selenium.WebDriver;import org.openqa.selenium.chrome.ChromeDriver;import org.openqa.selenium.ie.InternetExplorerDriver;public class Test_ShotScreen public static void main(String args) throws IOException, InterruptedException String url = ;/打开chrome WebDriver dr = new InternetExplorerDriver(); dr.get(url); /这里等待页面加载完成 Thread.sleep(5000); /下面代码是得到截图并保存在D盘下 File screenShotFile = (TakesScreenshot)dr).getScreenshotAs(OutputType.FILE); /FileUtils.copyFile(screenShotFile, new File(D:/test.png); FileUtils.copyFile(screenShotFile, new File(D:AutoScreenCapture + getCurrentDateTime()+ .jpg); dr.quit(); public static String getCurrentDateTime()SimpleDateFormat df = new SimpleDateFormat(yyyyMMdd_HHmmss);/设置日期格式/System.out.println(df.format(new Date();return df.format(new Date();19、webdriver与selenium切换/ You may use any WebDriver implementation. Firefox is used here as an exampleWebDriver driver = new FirefoxDriver();/ A base url, used by selenium to resolve relative URLs String baseUrl = ;/ Create the Selenium implementationSelenium selenium = new WebDriverBackedSelenium(driver, baseUrl);/ Perform actions with seleniumselenium.open();selenium.type(name=q, cheese);selenium.click(name=btnG);/ Get the underlying WebDriver implementation back. This will refer to the/ same WebDriver instance as the driver variable above.WebDriver driverInstance = (WebDriverBackedSelenium) selenium).getWrappedDriver();/Finally, close the browser. Call stop on the WebDriverBackedSelenium instance/instead of calling driver.quit(). Otherwise, the JVM will continue running after/the browser has been closed.selenium.stop();20、webdriver支持sariDesiredCapabilities capabilities = new DesiredCapabilities();capabilities.setBrowserName(safari);CommandExecutor executor = new SeleneseCommandExecutor(new URL(http:/localhost:4444/), new URL(/), capabilities);WebDriver driver = new RemoteWebDriver(executor, capabilities);21、suite之间不应该存在依赖，虽然代码static存在依赖，但是浏览器之间不是同一个driver了。22、如何上传文件Yup the Selenium devs thought about this ages ago. You can just use driver.findElement(By.id(“foo”).sendKeys(“AbsoluteFileLocation”); If the element you are sending text to is and it will upload the file.23、如何下载参考/index.php/2012/07/how-to-download-files-with-selenium-and-why-you-shouldnt/ 24、校验图片driver.get(https:/demo.mynexi
