在运行时突出显示 WebDriver 中的元素

I would be grateful if someone can please provide me with some code that I can try, also where would that code fit into the class below — sorry my Java skills aren't all that great.

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);
        }
    }   
}

推荐答案

在 WebDriver(从 v2.21.0 开始).您可以尝试替换通常的 findElement(By) 方法与使用 JavaScript 突出显示找到的元素的调整方法:

// 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;
}

// 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;
        }
    }
}

/*
 * 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']

}
// highlight the element
elem.style.border = '2px solid red';
return border;

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];
