Pros and Cons | Selenium WebDriver

-
In today's IT companies, for automating Web Applications, Selenium WebDriver is highly used and is the most common free open source tool. Anyone and everyone can get hold of it within a certain time to start with automating different applications. I will be listing down various advantages and disadvantages of Selenium WebDriver in this article.

Before Starting with the advantages of Selenium WebDriver, let me give a brief introduction of Selenium. Selenium was introduced in 2004 by ThoughtWorks in order to automate web applications. With time, various components were released namely - Selenium IDE, Selenium RC, Grid and lastly WebDriver.

Advantages of using Selenium WebDriver -

  1. Selenium is an open source. No need of licenses unlike QTP. Everyone and anyone can download, install and learn it quickly.
  2. It supports multiple languages. No need to learn an additional language to automate web applications using selenium. Various programming languages supported are - Java, C#, .net, Python, Javascript, ruby, perl, php.
  3. Works across all the platforms such as Mac, Windows, Linux, unix.
  4. Supports cross browser testing. Can be operated on different browsers such as Chrome, opera, firefox, IE, Safari.
  5. Supports Headless execution without using any browser using HTMLUnitdriver and PhantomJS.
  6. It can be integrated with any open source unit testing frameworks such as Junit, Test NG.These are Test- driven Development frameworks(TDD).
  7. It supports Behavior-Driven Development frameworks such as Cucumber, Serenity and JBehave. 
  8. It is very light weight and is available in the form of API.
  9. Supports CI-CD Integration such as Jenkins.
  10. Can be executed in local machines as well as VM/ Remote/ Server. Few of the platforms are Docker, AWS, BrowserStack, Saucelabs.
  11. Allows you to use wrappers extensively such as Appium(Mobile Testing), Protractor(For Javascript), Watir(Ruby), Robot Framework(Python).
Disadvantages of using Selenium WebDriver -

  1. No support is provided by the team.
  2. Programming prerequisite is required before starting off with Selenium WebDriver.
  3. Incapable of automating Desktop based applications.
  4. No feature to generate Reports such as QTP does.
  5. Inability to automate Bar codes or captchas.

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

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 ...
