有人可以帮忙吗!

在 WebDriver 中执行测试期间,如何突出显示以下课程中的所有 Web 元素?使用 Selenium RC,它非常简单,但使用 WebDriver 我正在苦苦挣扎。

如果有人能提供一些我可以尝试的代码,我将不胜感激,以及该代码在哪里适合下面的类 - 抱歉,我的 Java 技能不是那么好。

package hisScripts;
import java.util.concurrent.TimeUnit;
import org.testng.annotations.*;
import org.testng.Assert;
import static org.testng.Assert.fail;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.interactions.Actions;


public class R_LHAS_Only_Account_Verification extends HIS_Login_Logout{
    public WebDriver driver;
    public String baseUrl;
    public int exeMonth;
    private StringBuffer verificationErrors = new StringBuffer();

    @BeforeClass
    @Parameters ({"browser1", "url", "executionMonth"})
    public void setUp(String browser1, String url, int executionMonth) throws Exception {
        exeMonth = executionMonth;
        baseUrl = url;

        if (browser1.equals("FF")) {
            driver = new FirefoxDriver();
        } else if (browser1.equals("IE")){
            driver = new InternetExplorerDriver();
        }       
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);    
    }       

    @Test
    public void R_LHAS_Reports() throws Exception {
        R_LHAS_Only_Login(baseUrl, driver);
        Assert.assertEquals("Kingston upon Thames (RB)", driver.findElement(By.xpath("//html/body/div[9]/div/div[3]/div/div/div")).getText());
        Assert.assertEquals("Average price", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr/td")).getText());
        Assert.assertEquals("% price change", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[2]/td")).getText());
        Assert.assertEquals("Lower quartile price", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[3]/td")).getText());
        Assert.assertEquals("Time to sell (weeks)", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[4]/td")).getText());
        Assert.assertEquals("% asking price achieved", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[5]/td")).getText());
        Assert.assertEquals("House price to earnings ratio", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[6]/td")).getText());
        Assert.assertEquals("Cost of buying outright - LQ 2 bed £pw", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[7]/td")).getText());
        Assert.assertEquals("Private rent 2 bed £pw", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[8]/td")).getText());
        Assert.assertEquals("80% private rent 2 bed £pw", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[9]/td")).getText());
        Assert.assertEquals("Social rent 2 bed £pw", driver.findElement(By.xpath("//table[@id='tableId']/tbody/tr[10]/td")).getText());                 
        R_LHAS_Only_Logout(baseUrl,driver);
    }

    @AfterClass(alwaysRun=true)
    public void tearDown() throws Exception {
        driver.quit();
        String verificationErrorString = verificationErrors.toString();
        if (! "".equals(verificationErrorString)) {
            fail(verificationErrorString);
        }
    }   
}

WebDriver(从 v2.21.0 开始)没有办法做到这一点。您可以尝试用findElement(By)一种调整过的方法替换通常的方法,该方法使用 JavaScript 突出显示找到的元素:

// Draws a red border around the found element. Does not set it back anyhow.
public WebElement findElement(By by) {
    WebElement elem = driver.findElement(by);
    // draw a border around the found element
    if (driver instanceof JavascriptExecutor) {
        ((JavascriptExecutor)driver).executeScript("arguments[0].style.border='3px solid red'", elem);
    }
    return elem;
}

既然你明白了,有一个改进的版本可以在border找到并突出显示新元素时恢复最后一个元素的原始元素:

// assuming JS is enabled
private JavascriptExecutor js = (JavascriptExecutor)driver;
private WebElement lastElem = null;
private String lastBorder = null;

private static final String SCRIPT_GET_ELEMENT_BORDER;
private static final String SCRIPT_UNHIGHLIGHT_ELEMENT;

void highlightElement(WebElement elem) {
    unhighlightLast();

    // remember the new element
    lastElem = elem;
    lastBorder = (String)(js.executeScript(SCRIPT_GET_ELEMENT_BORDER, elem));
}

void unhighlightLast() {
    if (lastElem != null) {
        try {
            // if there already is a highlighted element, unhighlight it
            js.executeScript(SCRIPT_UNHIGHLIGHT_ELEMENT, lastElem, lastBorder);
        } catch (StaleElementReferenceException ignored) {
            // the page got reloaded, the element isn't there
        } finally {
            // element either restored or wasn't valid, nullify in both cases
            lastElem = null;
        }
    }
}

还有剧本!我使用FileUtils.readFileToString().

SCRIPT_GET_ELEMENT_BORDER(取自该站点的 IE 友好版本),如果它通过更改背景颜色(例如,仅底部边框)来突出显示,则会更短。但这是最好的一个:)。

/*
 * Returns all border properties of the specified element as String,
 * in order of "width style color" delimited by ';' (semicolon) in the form of:
 * 
 * "2px inset #000000;2px inset #000000;2px inset #000000;2px inset #000000"
 * "medium none #ccc;medium none #ccc;1px solid #e5e5e5;medium none #ccc"
 * etc.
 */
var elem = arguments[0]; 
if (elem.currentStyle) {
    // Branch for IE 6,7,8. No idea how this works on IE9, but the script
    // should take care of it.
    var style = elem.currentStyle;
    var border = style['borderTopWidth']
            + ' ' + style['borderTopStyle']
            + ' ' + style['borderTopColor']
            + ';' + style['borderRightWidth']
            + ' ' + style['borderRightStyle']
            + ' ' + style['borderRightColor']
            + ';' + style['borderBottomWidth']
            + ' ' + style['borderBottomStyle']
            + ' ' + style['borderBottomColor']
            + ';' + style['borderLeftWidth']
            + ' ' + style['borderLeftStyle']
            + ' ' + style['borderLeftColor'];
} else if (window.getComputedStyle) {
    // Branch for FF, Chrome, Opera
    var style = document.defaultView.getComputedStyle(elem);
    var border = style.getPropertyValue('border-top-width')
            + ' ' + style.getPropertyValue('border-top-style')
            + ' ' + style.getPropertyValue('border-top-color')
            + ';' + style.getPropertyValue('border-right-width')
            + ' ' + style.getPropertyValue('border-right-style')
            + ' ' + style.getPropertyValue('border-right-color')
            + ';' + style.getPropertyValue('border-bottom-width')
            + ' ' + style.getPropertyValue('border-bottom-style')
            + ' ' + style.getPropertyValue('border-bottom-color')
            + ';' + style.getPropertyValue('border-left-width')
            + ' ' + style.getPropertyValue('border-left-style')
            + ' ' + style.getPropertyValue('border-left-color');
}
// highlight the element
elem.style.border = '2px solid red';
return border;

SCRIPT_UNHIGHLIGHT_ELEMENT

var elem = arguments[0];
var borders = arguments[1].split(';');
elem.style.borderTop = borders[0];
elem.style.borderRight = borders[1];
elem.style.borderBottom = borders[2];
elem.style.borderLeft = borders[3];

欢迎任何问题、注释、请求和改进!

在 webdriver中为高亮元素HighlightElement
创建一个类

HighlightElement.java

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebElement;

import com.project.setup.WebDriverManager;

public class HighlightElement {

    public static void highlightElement(WebElement element) {
        for (int i = 0; i <2; i++) {
            JavascriptExecutor js = (JavascriptExecutor) WebDriverManager.driver;
            js.executeScript("arguments[0].setAttribute('style', arguments[1]);", element, "color: yellow; border: 2px solid yellow;");
            js.executeScript("arguments[0].setAttribute('style', arguments[1]);", element, "");
            }
        }
}

您可以使用

HighlightElement.highlightElement(driver.findElement(By.xpath("blaah blaah"));)

在您的测试中 使用 xpath“ blaah blaah ”突出显示 WebElement。

JavaScript: 查找元素Xpath并在其周围绘制边框,

使用 styleObj。setProperty (CSS propertyName, CSS propertyValue, priority) 方法。 element_node.style.setProperty ("background-color", "green", null);

在此站点上测试 js 代码:https ://developer.chrome.com/devtools/docs/console

var xpath = '//html/body/div/main/article/nav';
if (document.evaluate){
var element_node = document.evaluate(xpath, window.document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null ).singleNodeValue;
element_node.style.setProperty ('border', '3px solid green', 'important');

alert('Working Fine in this browser version');
}else{
alert('document.evaluate is Not supported by Internet Explorer');
}

public static void drawBorder(WebDriver driver, String xpath){
        WebElement element_node = driver.findElement(By.xpath(xpath));
        JavascriptExecutor jse = (JavascriptExecutor) driver;
        jse.executeScript("arguments[0].style.border='3px solid red'", element_node);
    }

我使用以下代码在我的 webdriver java 代码中使用 javascript 执行器突出显示:

//我在函数“flash”下面调用

    public static void flash(WebElement element, WebDriver driver) {
        JavascriptExecutor js = ((JavascriptExecutor) driver);
        String bgcolor  = element.getCssValue("backgroundColor");
        for (int i = 0; i <  3; i++) {
            changeColor("rgb(0,200,0)", element, js);
            changeColor(bgcolor, element, js);
        }
    }
    public static void changeColor(String color, WebElement element,  JavascriptExecutor js) {
        js.executeScript("arguments[0].style.backgroundColor = '"+color+"'",  element);

        try {
            Thread.sleep(20);
        }  catch (InterruptedException e) {
        }
     }

希望有帮助:)

这里是在 selenium 中突出显示元素的代码: 首先创建一个类:

package com.demo.misc.function;

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;

public class Miscellaneous 
{
    public static void highLight(WebElement element, WebDriver driver)
    {
        for (int i = 0; i <2; i++) 
        {
            try {
                JavascriptExecutor js = (JavascriptExecutor) driver;
                js.executeScript("arguments[0].setAttribute('style', arguments[1]);", element, "color: black; border: 4px solid red;");
                Thread.sleep(500);
                js.executeScript("arguments[0].setAttribute('style', arguments[1]);", element, "");
                Thread.sleep(500);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

    }

}

然后你可以通过以下方式调用它:

driver.get(baseUrl);
            Thread.sleep(2000);
            WebElement lnkREGISTER = driver.findElement(By.linkText("REGISTER"));
            Miscellaneous.highLight(lnkREGISTER, driver);
            lnkREGISTER.click();

我不知道在 WebDriver 中有任何方法可以做到这一点,但看起来 Selenium WebDriver 中存在一个类,它应该可以让您访问大部分(如果不是全部)RC API。我不知道如何使用 WebDriver 实际执行此操作。

WebDriverBackedSelenium类看起来包含您习惯的大部分 RC api,包括getEval

要创建 type 的对象WebDriverBackedSelenium,只需传入您已经使用的驱动程序以及测试站点的基本 URL

WebDriverBackedSelenium wdbs = new WebDriverBackedSelenium(driver, "http://www.google.com");

我使用 ExtentReport 作为报告工具,并且在失败的测试步骤中将图像添加为 base64 格式,这样我就可以在输出报告中的文本之后立即显示它们。当我截取屏幕截图并想要突出显示元素以便在屏幕截图中更明显时,我使用以下方法突出显示 -> 屏幕截图 -> 取消突出显示。

private void highlightElement(WebElement elemToHighlight) {
    if (_driver instanceof JavascriptExecutor) {
        ((JavascriptExecutor) _driver).executeScript("arguments[0].style.border='3px solid red'", elem);
    }
}


public String addScreenshotToHTML(WebElement... elmsToHighlight) {
    String result;
    List<String> initStyle = new ArrayList<>();
    if (elmsToHighlight.length > 0) {
        for (WebElement elem : elmsToHighlight) {
            initStyle.add(elem.getCssValue("border"));
            highlightElement(elem);
        }
    }
    String screenshot = ((TakesScreenshot) _driver).getScreenshotAs(OutputType.BASE64);
    // NOTE: add the <img> tag content between the <a> tags with the Base64 image
    // <a href='" + filePath + "' target='_blank'></a>
    result = "<img onclick='(function(){var image=new Image();image.src=\"data:image/png;base64," + screenshot
            + "\";var w=window.open(\"\");w.document.write(image.outerHTML);})()' style='width:400px; cursor:pointer;' src='data:image/png;base64,"
            + screenshot + "'>";
    if (elmsToHighlight.length > 0) {
        for (WebElement elem : elmsToHighlight) {
            jsExec().executeScript("arguments[0].style.border='" + initStyle.get(0) + "'", elem);
            initStyle.remove(0);
        }
    }
    return result;
}

希望有帮助

这对我有用。改进了之前在此线程上提交的代码。

public static WebDriver HighlightElement(WebDriver driver, WebElement element){ 
    if (driver instanceof JavascriptExecutor) {
        ((JavascriptExecutor)driver).executeScript("arguments[0].style.border='3px solid red'", element);
    }
    return driver;
}
public static WebDriver UnhighlightElement(WebDriver driver, WebElement element){   
    if (driver instanceof JavascriptExecutor) {    
        ((JavascriptExecutor)driver).executeScript("arguments[0].style.border=''", element);
    }
    return driver;  
}

调用这两个函数一次突出显示,一次取消突出显示

要突出显示元素,您可以使用以下命令:

JavascriptExecutor js =(JavascriptExecutor)driver;
js.executeScript("arguments[0].style.border='5px dotted yellow'", element);
