The getCssValue() method in Selenium WebDriver

Question

The getCssValue() method in Selenium WebDriver

In my current exercise, I am using the cssGetValue method to extract the value from a specific web element's CSS property.

I have two main inquiries:

Why did the cssGetValue method return the value 13px, and which exact web element is being referenced by this method? 1a. To retrieve the CSS property for the section labeled as "By ID," how can I adjust my code in order to obtain the CSS property value for the id="by-id" section?

Although I used the driver.close() method, it did not successfully close the browser upon script completion. Can you please clarify why the driver.close() method failed to work in this particular scenario?

Below is a segment of my code:

package wd_findElementBy;

import java.util.List;

import org.junit.Test;

import org.junit.Before;

import org.junit.After;


import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;


public class SearchWebElements 
{

WebDriver driver = new FirefoxDriver();
private String baseUrl= "http://docs.seleniumhq.org/docs/03_webdriver.jsp#introducing-the-selenium-webdriver-api-by-example";

@Test
public void findElements(){
driver.get(baseUrl);

try{
    List<WebElement> elements = driver.findElements(By.id("by-id"));
    System.out.println("number of elements: " + elements.size());

    for(WebElement ele : elements){
        System.out.println(ele.getTagName());

        System.out.println("get the text for web element with id='by-id'");
        System.out.println("----------------------------------------------");
        System.out.println(ele.getText());
        System.out.println("----------------------------------------------");
        System.out.println(ele.getAttribute("id"));
        System.out.println(ele.getCssValue("font-size"));

    }
}

finally{
    //driver.close();
    driver.quit();
}


}

}

Answer №1

Affirmative, everything is accurate.

Check out this visual guide on locating the font-size attribute using Firebug.

Given that identifiers should be unique (at least within this context), you can forgo using findElements to search for a collection of elements with the identifier by-id. Instead, utilize findElement to retrieve the specific element.

try{
        WebElement byId = driver.findElement(By.id("by-id"));

        System.out.println(byId.getTagName());

        System.out.println("extracting text from web element with id='by-id' ");
        System.out.println("------------------------------------------------------------");
        System.out.println(byId.getText());
        System.out.println("------------------------------------------------------------");
        System.out.println(byId.getAttribute("id"));
        System.out.println(byId.getCssValue("font-size"));
    }
}

Answer №2

To access the CSS value:

driver.findElement(By.id("by-id")).getCssValue("font-weight");//you can also check other CSS properties like color, margin etc.

To close the browser after running the script:

driver.quit();

class GetCssValuesProgram {

public WebDriver driver;
private By searchButtonLocator = By.name("btnK");

@BeforeClass
public void setup() {
    driver = new FirefoxDriver();
    driver.get("http://www.google.com");
}

@Test(priority=1)
public void getButtonColor()  {
    WebElement searchButton = driver.findElement(searchButtonLocator); 
    System.out.println("Button color before hover: " + searchButton.getCssValue("color"));
    Actions action = new Actions(driver);
    action.moveToElement(searchButton).perform();
    System.out.println("Button color after hover : " + searchButton.getCssValue("color"));
}

@Test(priority=2)
public void getButtonFontSize() {
    WebElement searchButton = driver.findElement(searchButtonLocator);
    System.out.println("Font size of the button " + searchButton.getCssValue("font-size"));
}

@Test(priority=3)
public void getButtonFontWeight(){
    WebElement searchButton = driver.findElement(searchButtonLocator);
    System.out.println("Font weight of the button "   +getFontWeight(searchButton) );
}

public String getFontWeight(WebElement element) {
    //Output will be 400 for font-weight:normal and 700 for font-weight:bold
    return element.getCssValue("font-weight");
}

@AfterClass
public void cleanup() {
    driver.quit();
}

}

Results:

Button color before hover: rgba(68, 68, 68, 1) Button color after hover : rgba(34, 34, 34, 1) Font size of the button 11px Font weight of the button 700

Answer №4

The correct value has been verified. To access the computed section in dev-tools, follow these steps:

Include the property name in the getCssValue function to retrieve relevant information.

Here are some examples:

        System.out.println("font-size = "+ele.getCssValue("font-size"));
        System.out.println("background = "+ele.getCssValue("background"));
        System.out.println("line-height = "+ele.getCssValue("line-height"));
        System.out.println("color = "+ele.getCssValue("color"));
        System.out.println("font-family = "+ele.getCssValue("font-family"));
