Introducing Selenium

-
Selenium has been widely accepted by the IT companies since it is an open-source tool and easy to learn. We will be introducing Selenium in this article deeply.

What is Selenium?

Selenium is primarily used for automating web-based applications. 

Selenium's tool suite - 

  1. Selenium IDE
  2. Selenium RC
  3. Selenium WebDriver
  4. Selenium Grid

Selenium IDE -

IDE stands for the Integrated development environment. Selenium IDE is basically a Firefox and Chrome plugin used to build test scripts. Its interface is user-friendly.  Primarily feature of Selenium IDE is to record user actions performed in the browser. Later it can be played back to record the behaviour of the application for testing purpose.

Selenium RC -


RC here stands for Remote Control. We need to have a dedicated Standalone server in order to work with Selenium RC. The script can be written in different languages in the editor. Refer to the architecture of Selenium RC shown above.

Selenium WebDriver -


Selenium Remote Control is officially depreciated and Selenium Webdriver is the successor of Selenium RC. It provides awesome features, including an Object-oriented API. Selenium WebDriver creates robust, browser-based regression automation suites and tests. 

  • WebDriver is used to automate different web browsers.
  • Compatible with different languages - Java, .Net, PHP, Python, Perl, Ruby, etc.
  • Selenium web driver is faster than Selenium RC because of simple arhitecture
  • Selenium RC needed the help of the RC server in order to interact with the browser.

Selenium Grid - 


Selenium Grid allows you to run your tests on different machines against different browsers in parallel. That is, running multiple tests at the same time against different machines running different browsers and operating systems. Selenium Grid supports distributed test execution. Selenium Grid can save your time significantly by running your tests in different machines in quick succession.

Recently Selenium WebDriver came up with version 4 in the market and introduced few new relative locators -

  • toRightOf()
  • toLeftOf()
  • above()
  • below()
  • near()



Hope the above article is useful if you want to learn about the pros and cons of Selenium web driver discussed in another article.

In this article, we will learn about Azure networking concepts such as architecture, microservices, virtual networks, VPNs, subnet, VPN gateways and most importantly Network Security Group(NSG). All these terms are to be understood if you appearing for AZ900 Microsoft Azure Fundamentals exam. Azure Networking In previous articles we have learnt about Micro- services and how they work, these are alos loosely coupled architecture. Some of the features includes Independent components interact with each other with the help of queues Can be updated and deployed independently Highly scalable Supports Asynchronous messaging N-tier Architecture Supports loosely coupled architecture Application divided into multiple tiers such that higher tier can access lower tier but not vice versa Tiers are re-usable and can be updated or replaced easily without any hassle. Three-tier in general Web Tier(front end) Application tier(back end) Data tier(Storage) Virtual Network Isolated network shared by few g...

Testing in CI/CD

-
If you are part of testing fraternity you would have heard CI/CD numerous times by now. It's the talk of the software testing town. In this article, we will cover the basics of CI/CD, what actually it is and how it is implemented in software testing. What is continuous integration? In simple terms, development teams can integrate their code into a shared repository. This helps in maintaining code quality and identifying potential issues with the local version of the code at an early stage. What is continuous delivery? Everything that is being continuously merged by the development team, is continuously deployed to the live environment. Continuous delivery is often coined as ‘Continuous Deployment’ as well. Since most developers work in parallel, continuously integrating their code into one repository would mean that the master branch is continuously updated with new features. In order to ensure that there is no compromise in the code quality with so many changes...

Azure Tutorials Series - IaaS vs PaaS vs SaaS

-
Image
We already have covered Public vs Private vs Hybrid differentiation in the previous article. In this article we will be covering three categories of cloud computing with relevant examples and details. Most of you might already be using these services in your daily day-to-day tasks unaware of the face that your organisation has already started the transition into the cloud. For an example, Office 365 is a active SaaS(Software as a service) that most of us uses, VMs are examples of IaaS(Infrastructure as a service) and Azure SQL Database is PaaS(Platform as a service). Now how do we differentiate between the three categories as a user? Will cover the details below. Infrastructure as a Service(IaaS) Service provider provides you the hardware User gets some control over the hardware, can customise operating system, storage and VMs. Ensuring service is up and running is shared responsibility While cloud provider makes sure that the hardware is functioning correctly, user needs to make sure ...
