Yes, all correct.

Here's a screenshot of where to find font-size through Firebug.

enter image description here

Since the ids are supposed to be unique (at least for this page), you don't need findElements to find a list of elements with id by-id and loop through, instead, you use findElement to get the element directly.

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

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

        System.out.println("get the text for 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"));
    }

Testing A Single Page Angular JS Applications

With the introduction of Angular JS, Google brought a paradigm shift in the world of web development. Gone were the days when static web pages consumed a lot of resources and resulted in a website that is slower to load and with each click on a button, resulting in a tiring page reload sequence. Dynamic single page websites or one page website became the new trend where with each user action, only the content of the page changed, sparing the user from experiencing a website full of slower page loads.

How to get started with Load Testing?

We have all been in situations while using a software or a web application, everything is running too slow. You click a button and nothing is happening except a loader animation spinning for an infinite time.

Cross Browser Automation Testing Using Watir

We are living in an era where software development demands for automation. Software development methodologies such as RAD(Rapid Application Development), Agile and so on requires you to incorporate automation testing as a part of your release cycle. There exist numerous test automation frameworks used for automation testing. Today, I will be picking up Watir an open source, selenium-based web driver used for browser automation. Cross browser automation testing using Watir would help you to ensure a good rendering user interface of your web app. If you are a beginner to automation testing and are unaware of basics then don’t worry as I will also be talking about browser automation, cross browser automation, parallel testing and what makes Watir special than other several tools and libraries. Without further ado, here we go!

How to Get Element by Tag Name In Selenium

Selenium locators are your key when dealing with locating elements on a web page. From the list of locators like ID, Name, Class, tag name, XPath, CSS selector etc, one can choose any of these as per needs and locate the web element on a web page. Since ID’s, name, XPath or CSS selectors are more frequently used as compared to tag name or linktext, people majorly have less idea or no working experience of the latter locators. In this article, I will be detailing out the usage and real-time examples of How to Get Element by Tag Name locators In Selenium.

Selenium 4 Tutorial:

LambdaTest’s Selenium 4 tutorial is covering every aspects of Selenium 4 testing with examples and best practices.
