Only 7% of the websites tested have a response time lower than 1 second.

Also more than 50% of the websites tested, almost 15k websites, have a response time greater than 5 seconds.

A higher response time translates indirectly in potential customers leaving your website.
How to Improve Your Page Load Speed by 50% in less than 30 Minutes? Here are a few hints which can make a huge difference:
  • minify assets (JS files, CSS files)
  • minify HTML
  • use CSS Image Sprites
  • optimise images
  • use CDN for hosting images and other assets (fonts etc) – inspect latency
  • move JS files at the bottom of your HTML page and CSS files at the top
  • group multiple CSS files and JS files into a single (minified) CSS or JS file if possible
  • eliminate Render-Blocking JavaScript and CSS (Async Javascript)
  • rely on browser caching
  • remove unused widgets, plugins
  • improve server side hardware (DB queries, hardware, etc)
  • more details on increasing rendering speed
As you saw above, there are loads of things you can do to improve your website rendering speed. We also offer a free website speed test.

If you want to open a new tab in the browser with Selenium WebDriver and Java, below we’ve listed some working examples. Have in mind that at the moment, Selenium WebDriver has no build-in ability to open new tabs or new windows, and because of this we have to force the browser to open the links in new tabs or in new windows. This may be implemented in a later version of Selenium WebDriver.

1. Open an existent link a a new tab using Selenium WebDriver and Actions

More details on how to locate web elements with Selenium WebDriver.

//identify the link in the page, that you want to open in a new tab of your browser's instance
WebElement link = driver.findElement(By.cssSelector(linkLocator));

//this action will click the WebElement with the link identified above, hold CONTROL Key (or COMMAND if you're using Mac), click the WebElement and relese the Keys.CONTROL (use Keys.COMMAND if you're using Mac).
new Actions(driver)

The code above works in all browsers.

2. Open an existent link a a new tab using Selenium WebDriver with CONTROL/COMMAND Key and T

There is also another option that may not work in Chrome browsers at the moment because of a limitation in the way keyboard inputs are simulated in ChromeDriver. Keys are sent directly to the render process, so any keyboard shortcut in the browser process will not be invoked by sendKeys() method.

String selectLinkOpeninNewTab = Keys.chord(Keys.CONTROL,"t");

Keys chord(CharSequence… value) method – Simulates pressing many keys at once in a “chord”. Takes a sequence of Keys.XXXX or strings; appends each of the values to a string, and adds the chord termination key (Keys.NULL) and returns the resultant string. Note: When the low-level webdriver key handlers see Keys.NULL, active modifier keys (CTRL/ALT/SHIFT/etc) release via a keyup event.

The code below will open the link in new Tab.


Then when you open a new tab in your browser, you have to switch to it to be able to work with the newly opened tab’s elements:

List tabs = new ArrayList&amp;lt;&amp;gt;(driver.getWindowHandles());

In order to switch back to the first tab, Selenium WebDriver offers the ability to switch back to the first tab, by executing the following code:


Quite often you may want to open a new tab in the same browser window that is running your Selenium WebDriver tests. Instead of opening a new browser, you can simply use the code below to open a new tab in the same browser:

String selectLinkOpeninNewTab = Keys.chord(Keys.CONTROL,"t");

You’d need to keep track of the window name(s) or ids to allow switching between them.

3. Open an existent link a a new window using Selenium WebDriver

//identify the link in the page, that you want to open in a new tab of your browser's instance
WebElement link = driver.findElement(By.cssSelector(linkLocator));

//this action will click the WebElement with the link identified above, hold SHIFT Key , click the WebElement and relese the Keys.SHIFT .
new Actions(driver)

If you ever asked yourself “What is the difference between Performance Testing and Load Testing”, below are listed some of the main characteristics of Performance Testing and Load Testing, and how are they different from one another.

What is Performance Testing?

Performance Testing represents the characteristics of a system, how fast is that system, in general it refers to the tests undertaken to determine how that system behaves and performs.

Prerequisites for Performance Testing

We need to have clearly defined goals before starting any performance tests. The goals defined will help us if after getting the performance tests results there is a need for system improvement.

Performance Testing Results

After running performance tests, you need to inspect the metrics like response and latency times, hits per second, throughput per second, errors (client side metrics) and CPU, Memory, I/O (server side metrics) for the system tested.

Performance Testing Goals

Set a base line for the system under test for future releases and potential improvement of the system. It helps to identify potential bottlenecks, that can be found at different levels: system level (client and server side), DB level, network level.

Most of the times, running performance tests can be a very time consuming and hard job. First you need to set a base line for your tests, then you need to tweak the tests (number of concurrent users, duration and ramp up period between concurrent users).

Use LoadFocus to performance test your application from the cloud.

What is Load Testing?

Load Testing is understanding how the system behaves under high volume of transactions. Let’s say you send an email campaign to 10000 addresses and you want to understand how your system behaves when most of those 10000 potential users will access your applications.

Load Testing helps you simulate similar scenarios in an controlled environment, and the goal of load testing is to see whether the application can sustain the increased load on the server or will it crash the servers. Use LoadFocus to cloud load test your application.

Load Testing is usually started with a low number of concurrent clients (users) and gradually increased over a given period of time until it reaches the desired load on the system. During this period, client side and server side metrics need to be inspected.

We’ve only touched the surface in terms of potential issues, performance testing and load testing tools and techniques that deserve to be mentioned in the context of performance and load testing. is a All-In-One Cloud Testing Platform for Load Testing and Performance Testing, Website Speed Testing, Automated Website Testing and Mobile Emulation for Websites, Mobile Applications and API Endpoints.

While testing different applications you will get to the need of testing the following scenario:

The user is opening the application, clicks the Overview button which sends the application
to background and reopens the application by choosing it from the recent used application.

To be able to do that you need to know how to implement two important actions:
1. Click the Overview button which send the application to background; for doing this you can use the following
code snippet written in Java:

    public void clickOverviewButton(){

2. Reopen the application from the recent applications; for doing this you can use the application name like in the following example written in Java:

    public void clickRecentAppByText(String appText){
		waitForElementByText(appText, 10);
		driver.findElement(By.xpath("//*[@text=\"" + appText + "\"]")).click();

Hope this helps with your daily testing tasks. Details on how to use the Overview, Home and Back buttons in Appium for Android

We’re pulling back the curtain on how we came with the idea for what we consider “The Ultimate Selenium WebDriver Testing & Hands-on Guide”

In the previous two years we’ve managed to post dozens of interesting new articles on our blog, and the increasing number of visitors prove that we are creating compelling and quality content.

Our main area of focus are testing articles on how to use Selenium WebDriver, Apache JMeter, LoadFocus and other testing tips and tricks.


Some of our most successful articles are listed below:


At the beginning, we were trying to promote LoadFocus as a Cloud Testing Framework, but our marketing efforts were failing, and nobody was actually visiting our website or signing up for our cloud service.

Then we stepped back and thought we really need to think about what can we do to drive more traffic to our blog and service.

So we started creating blog post with interesting, complete and quality content related to Automated Functional Testing with Selenium WebDriver. We also created our own Automated Website Testing service provided by LoadFocus.

We’ve added a list of how to’s articles on how to locate elements with Selenium WebDriver, how to take a screenshot with Selenium WebDriver, how to wait for an web element with Selenium WebDriver, how to select a dropdown, how to use explicit and implicit waits and timeouts and more other interesting topics.

The only difference is that all the articles we’ve written come from our own pain points, and we’ve trying to provide the FULL information related to the topic, with no need to go anywhere else to search for an answer to your questions. Working examples are present in most of our blog posts and we update them once we get a new update.

So, in the past couple of weeks, we came with the idea, to create our own Online Course – “The Ultimate Selenium WebDriver Testing & Hands-on Guide”. We like to call it “Ultimate”, since we believe it’s going to be something different from what’s there on the market, something easier and faster for you to learn. Instead of watching 100 or 200 hours of Online Courses, we try to compress ours in just 5 hours.

We created the Online Course presentation page, and we decided on the most important things to get discussed and we’ve generated our first curriculum.

Hope you’ll enjoy it, and have a look at “The Ultimate Selenium WebDriver Testing & Hands-on Guide”.
