Selenium is an open-source, automated, and powerful testing tool that all web app developers must be informed of. Testing performed with Selenium is often described as Selenium automated testing. But, Selenium is not just an instrument, but rather an assortment of tools, each of which caters to various Selenium automation testing requirements. All of this can be gone through in the Selenium Course Online. In this guide, you’ll discover more concerning Selenium and the different types of Selenium automated testing tools.
An Introduction Selenium Automation Testing
However, before we get into Selenium automation testing, let’s first discuss the necessity for Selenium automated testing and the way Selenium became a reality in the first place.
Manual testing, an essential element of the development process, it is not without its flaws among them is that it is tedious and repetitive.
One of the drawbacks of Selenium Automation Testing is it’s only with web-based applications, leaving desktop and mobile applications on the outside. However, software like Appium or HP’s QTP and others are able to be used for testing mobile and software.
Selenium Automation Testing Tools
Selenium comprises a set of tools designed to facilitate the process of testing. For more information visit this site: cnnnewsworld
Selenium IDE
The next section in the Selenium Automation Testing tutorial covers all you should know about Selenium IDE. It is a conventionally user-friendly interface that records users’ actions to create automatized test programs. It’s a Firefox as well as a Chrome plugin, which is generally employed as a tool for prototyping. It was designed for speeding up the development of automated scripts.
IDE was discontinued in August 2017, when Firefox updated to the latest Firefox 55 version that was no longer compatible with the Selenium IDE. Applitools revamped the original Selenium IDE and released a new version in the last few days. The new version has numerous improvements, including:
- Test scripts can be reused
- Troubleshooting test scripts
- Selenium side runner
- Control flow statements for the provision of control
- Improvements to locator functionality
Let’s now take a look at to a more thorough review of Selenium IDE.
Installing IDE:
Step 1: Start the Firefox browser.
Step 2: Select the menu at the upper right corner.
Step 3: Click Add-ons from the drop-down menu.
Step 4: Click on Add-ons to the left and enter “Selenium IDE”
Step 5: Click Add to Firefox
After installation After installation, after installation, the Selenium IDE icon appears on the top right in the web browser. When you click it you will see a welcome message.
Recording the results of a test
In this portion of the Selenium automated testing tutorial, we’ll learn how to take the results of a test. We will first create a test that is new to a project. Give a name to your project. In this instance, we’ll name demo_project. Prior to recording, it is necessary to enter an appropriate URL. The recording starts when the browser has navigated through this link. Let’s go through the login for Facebook.
Clicking “Start Recording” will send you to the Facebook page to begin recording users’ interactions. The user has the option to end the recording. Every action of the user is recorded and converted into a script.
Save Your Work
The next step is to learn how to back up your project with the Selenium Automation Testing tutorial. To save the work you’ve completed in the IDE Click the save icon located in the upper-right corner of the IDE. It will prompt you to enter an alias and a location of where you can keep the file. This will result in a singular file that has a side extension.
Playback
In-browser: You are able to play backtests within the Selenium Automation Testing IDE by choosing the test you would like to play, and then click “Play”.
For playback of cross-browser browsers, it is possible to make use of the command line-runner.
Selenium Remote Control (RC)
Another fascinating topic that this Selenium automation tutorial discusses is Remote Control or RC. The tutorial also discusses the reasons the reason RC first came into existence in the first place.
A set of JavaScript functions that could interpret as well as execute Selenese commands by using the web browser’s inbuilt JavaScript interpreter. Selenium-Core then was integrated into the browser.
Let’s take a look at JavaScript, test.js used by google.com. The program is able to access websites such as google.com/mail as well as google.com/login inside google.com. google.com domain.
But, it is not able to access the elements of other domains, such as Yahoo.com. The local copies of Selenium-Core and the web browser needed to be installed in order they were part of one domain. This is known as the Same Origin Policy, and Selenium RC was developed to overcome this issue. The server is an application that is configured by a client HTTP proxy that “tricks” your browser to thinking the Selenium Core and the web application that is being tested have the same source.
Therefore, Selenium RC is a server developed in Java that allows creating tests for applications in different programming languages, including Java, C#, Perl, PHP, Python, and many more. The RC server receives requests from the user’s program and sends Sequence-Core JavaScript (SJSC) commands to the browser.
Selenium WebDriver
The next part of this Selenium Automated Testing Tutorial explains all aspects of Selenium WebDriver. It was created by Simon Stewart in 2006; Selenium WebDriver was the first framework for testing cross-platform that was able to configure and manage the browsers at the OS level. It functioned as an interface for programming to build and execute test cases.

Contrary to Selenium RC, WebDriver does not require a core engine, like RC and is able to interact natively with browser apps. WebDriver can also be used with programming languages such as Python, Ruby, PHP and Perl. It is also compatible with frameworks such as TestNG and JUnit to support Selenium automated testing management.
Selenium WebDriver’s structure is simple and simple to comprehend:
Figure: Selenium WebDriver architecture
- Selenium test script Selenium test scripts are the program written in one of the above programming languages which are then read by the software driver.
- JSON Wire Protocol – JSON Wire Protocol is an efficient way to transfer information between servers and the client. JSON Wire Protocol is the industry norm for many web-based services.
- Drivers for browsers – Selenium utilizes drivers that are specific to each browser, to create a secure connection to the browser.
- Browsers The browser Selenium WebDriver works with a variety of web browsers that allow you to run and test applications.
Selenium WebDriver tutorial –
- Download and install Java 8.x or greater version. Install the most recent version of Java and the Java software development kit.
- Download and set up Eclipse or any other Java software of your choice
The file you download will be an unzipped file. Unzip the file to the folder you prefer. After you have unzipped it you can launch your .exe Eclipse file.
It is the next stage to set up your workspace. Select the directory in which you’d like to save the entirety of your work and hit the start icon.
When it is started after launch, the IDE workbench will look something like this.
- Download Selenium WebDriver Java Client –
- Go to the official Selenium page.
- Scroll down the page to find Selenium Client as well as WebDriver Language Bindings.
- Select the “Download” link to download the Java Client Driver, as depicted in the image.
After downloading, you can unzip the file and place it in the directory. It contains the Jar files that are required to configure Selenium WebDriver within the IDE.
- Download the browser driver The automation scripts should be compatible with all browsers. Each browser that Selenium supports have driver files. They are required for running the scripts. To get started, download the most recent driver file on this page.
- Configure the Selenium WebDriver – The final step is to set up Selenium WebDriver. Selenium WebDriver with the Eclipse IDE. Simply, let’s make an entirely new Java project in order to build the test program.
Create a project name, and choose the JRE you want to utilize. It is recommended to choose your default JRE. Choose it and click close.
The second and most important step is to upload to the download of Java executable files to the project [Step 3. To do this, right-click on the project, select Build Path, then Configure Build Path.
Select libraries and then add External JARs.
Navigate to the folders where you’ve stored your JAR files. Choose the executable JAR files. Select open to add them to your computer.
Click on the folder libs and select the desired files and then open them.
After you’ve added your library’s files you can click Apply after which click Close.
This means that you have successfully set up the Webdriver by using Eclipse. Eclipse IDE. You are now able to go ahead and create your very first test program.
To do this, right-click on the Src folder >> New>> Class
Create a simple test script that opens your Firefox browser and then opens Facebook’s homepage. Facebook homepage. The script is below.
Note the second argument for this method of setting property is where you have installed your browser’s driver. In our instance, we’ve installed the Gecko driver. So, we simply copy and paste the path and the file’s name.
Click on Run>>Run As>>Java Application.
Selenium Grid
In the next segment in this Selenium automation test tutorial, you will learn more concerning Selenium Grid, which Patrick Lightbody created to minimize the duration of Selenium automated testing. Selenium Grid allows the parallel testing of tests across various browsers and operating systems, making it possible for parallel execution. Grid is extremely flexible and integrates with other suite components to provide simultaneous performance.
Figure: Selenium Grid
The Grid is comprised of the hub, which is connected to various nodes. It is informed of the test to be conducted along with information regarding the system operating and the browser that it will be used. The Grid chooses the node that meets the specifications (browser as well as the platform) and is able to pass the test on that particular node. The node is now running its browser, and it executes the Selenium commands that it has within it.
