Origin of Selenium

Jason Huggins developed the testing tool called Selenium within the year of 2004. To perform repetitive automation testing course online against the web-based applications, he developed a JavaScript, and later the name was changed as Selenium. Earlier the name of the program is called as “JavaScript Runner”

Why Selenium?

Various companies are spending many money to shop for an automation tool for testing but Selenium are going to be available for free of charge downloads due to the open-source concept.

Some other tools which are available for automation testing are supported pricing and for a few features, we’ve to enable the upgrade version by paying. In this case, Selenium stands one step ahead.

Anyone can download the newest version of the software from the selenium website. It’s not only an open-source tool but also can be modified by their needs. Testers can make changes based on their needs and requirements.

The above-mentioned points make it more feasible among the businesses trying to find skilled selenium testers. To become a talented selenium tester, join Amitysoft Automation Training Institute in Chennai.

Selenium is for Automation Testing

Selenium is an open-source testing tool that allows you to test the performance of the web-based application. The core feature of selenium is to check the power beyond cross browsers testing and various operating systems. The important a part of selenium are going to be divided into 4 types

1. Selenium IDE

2. Selenium RC

3. Web Driver

4. Selenium Grid

Selenium Testing Suite

Selenium IDE, Selenium RC, Selenium Web-driver, Selenium Grid are called Selenium Testing Suite. After knowing the advantages of testing suites, selenium has become the foremost popular testing tool for automation.

Selenium testing has reduced the time and therefore the cost to realize performance goals. To test the GUI and therefore the web application, it’ll be their first choice for the testers to check.

1. Selenium IDE

The full sort of Selenium IDE is that the Selenium Integrated Development Environment, which is one among the only frameworks within the selenium testing suite and it’s the simplest one to learn for beginners. IDE is that the Firefox Plugin, so you’ll easily install it like other plugins.

Because of the simplicity of IDE, it are often only used because the “Prototyping Tool”. In case, if you would like to make more advanced test cases, then you ought to go for Selenium RC or Selenium Web Drivers.

PROS and CONS:

1. Easy to use and install → Available only in Firefox

2. No Programming Knowledge required → Designed only to create prototypes of test cases

3. Has build-in test formats usable in Selenium RC and Selenium Webdriver → Test execution is very slow when it’s compared to Selenium RC and Selenium Web Driver.

2. Selenium RC (Remote Control)

Selenium RC was the flagship framework of testing for the entire selenium projects for an extended time. This is the primary automated web testing tool that permits the user to use their preferred languages they need . As of now version of two .25.0, Selenium RC can support the below-mentioned languages,

• Java

• C#

• PHP

• Python

• Perl

• Ruby

PROS and CONS:

1. It can perform cross-browser and cross-platform testing → Installation is way more complicated than IDE.

2. Supports Data-Driven testing → Needs selenium RC server to run.

3. Faster exception than IDE → but slower execution when it’s compared to web drivers.

3. Selenium Web-driver

Selenium Web-driver is that the successful tool after Selenium RC then far it’s one among the foremost important parts of Selenium Testing Suite. Selenium web driver provides you the programming interface to make and execute the test cases supported the wants.

Testing scripts are written to acknowledge the online elements then desired steps are performed on those written web elements.

Web driver calls the tactic on to different browsers hence the selenium web driver has separate drivers for every browser. Some of the foremost used web drivers are mentioned below,

• Mozilla Firefox (Gecko Driver)

• Google Chrome Driver

• Internet Explorer Driver

• Opera Driver

• Safari Driver

• HTML Unit Driver

PROS and CONS

1. Simple installation when it’s compared to Selenium RC → but it’s more complicated than IDE

2. Communicates directly to the web browsers → but it requires the programming knowledge

3. No need for separate components like the RC server → has no build-in mechanism for logging runtime messages and generates test results.

4. Selenium Grid

Selenium grid is also an important part of the selenium suite which allows you to run the test cases on different machines against different browsers in parallel. In other words, we will run our test cases in several machines running in several browsers and operating systems.

Selenium Grid goes alongside the HOB-NODE Architecture to achieve the parallel execution of test scripts. Hub controls the execution of the test scripts on various nodes.

Advantages and Disadvantages of Selenium

Advantages:

1. Selenium is an open-source software testing tool

2. Selenium supports various languages to create and execute programs.

3. Selenium supports various kind of browsers (Mozilla Firefox, Google Chrome, IE, Opera, Safari)

4. Selenium supports parallel test case execution

5. Selenium supports various operating systems (Windows, Linux, etc)

Disadvantages:

1. There is no technical support from anybody but UFT provides technical support from HP

2. It supports only web-based applications

3. There is limited support for image testing

4. No Build-In report facility

5. No testing tool integrated for test management
