Selenium is one of the most popular and powerful automation testing platforms. Selenium certification is not a tool but a suite of components, which are developed by open source community. The current version of Selenium suite, as of 2017, is 3.0.

In addition to Selenium 3.0, there are several automation testing tools available in the market e.g. HP UFT (Unified Functional Testing tool), TestComplete etc.

However, before we proceed further, let’s look at some of the key aspects of Selenium 3.0 suite:

• It’s open source meaning that it’s completely free
• It supports multiple languages for writing automation scripts like Java, Python, C# etc
• It also supports multiple browsers
• The open source community is wide spread and keeps on adding new components and upgrading the existing versions.

Selenium 3.0 Suite

Selenium 3.0 suite comprises of multiple components. The latest version of selenium is 3.0, which was released in 2017. Let’s have a brief look at the evolution of Selenium from the early days to the latest version 3.0.

Selenium 1.0

Selenium can be traced back to Thoughtworks’ Jason Higgins. However, several teams/individuals worked to develop various components independently. Selenium IDE was developed by Shinya Kasatani, while Selenium RC Server (Remote Control Server) was developed by Dan Fabulich and Nelson Sproul (of erstwhile BEA systems, acquired by Oracle). Jason, with support of seniors and colleagues, develop Selenium web driver and released it as Open source.

DevOps is one of the hottest trends in the software industry and successful DevOps implementation is the goal of most progressive IT organizations (see chart below, courtesy of Google Trends). Devops certification (short for development and operations) is a set of automated software practices that combine software development (Dev), testing and IT operations (Ops) to shorten the software development life cycle while delivering features, fixes, and updates frequently in alignment with the business’ objectives.

DevOps is typically cross-functional (people from different IT-related business units) and uses different software tools. These tools usually fit into one or more of the following categories:

• Coding – code development and review, source code management tools, code merging
• Building – continuous integration tools (like Jenkins), build status
• Testing – continuous testing tools (like QuerySurge, Selenium, Cucumber, JMeter) that provide feedback on business risks
• Packaging – artifact repository, application pre-deployment staging
• Releasing – change management, release approvals, release automation
• Configuring – infrastructure configuration and management, infrastructure as code tools
• Monitoring – applications performance monitoring, end-user experience

While we’re at it, let’s add a few more terms to the DevOps movement:

• Continuous Integration (CI). Continuous Integration is about automating build and test processes to make sure the resulting software is in a good state, ideally every time a developer changes code. CI helps development teams avoid integration issues where the software works on individual developers’ machines, but it fails when all developers combine their code.
• Continuous Delivery (CD). Continuous Delivery goes one step further to automate a software release, which typically involves packaging the software for deployment in a production-like environment. The goal of CD is to make sure the software is always ready to go to production, even if the team decides not to do it for business reasons.
• Continuous Deployment (also CD). Continuous deployment goes one step further than continuous delivery. With this practice, every change that passes all stages of your production pipeline is released to your customers. There’s no human intervention, and only a failed test will prevent a new change to be deployed to production.
• Continuous Testing. One of the hottest buzz terms in the testing world, continuous testing is the process of executing automated tests as part of the delivery pipeline to obtain immediate feedback on the business risks associated with a release candidate. Continuous testing cannot be implemented without test automation.

DevOps principles demand strong interdepartmental communication and rely heavily on automation tools.
Data is growing geometrically and applying automation to develop, deploy and validate/test the data is becoming more critical, as businesses are implementing BI & Analytics to make sense of their data and to leverage it in hopes of providing a competitive advantage.

Culture

DevOps is primarily typically the culture and mindset forging strong collaborative bonds between computer software development and system businesses teams. This specific culture is created on below pillars.

Constant collaboration and communication.

These have been the building blocks regarding DevOps since their dawn. Your team should work cohesively with the understanding of the needs and expectations of all members.

Gradual changes.

The implementation of progressive rollouts allows delivery teams to release a product to users while having an opportunity to make updates plus roll back if something goes incorrect.

Shared end-to-end responsibility.

If every member regarding a team goes towards one aim and is also equally in charge of task management by beginning to ending, they work consistently and look intended for ways of assisting other members’ duties

Early problem-solving.

DevOps requires that jobs be performed because early in the particular project lifecycle because possible. Therefore, within case of any kind of issues, they will certainly be addressed faster. Training for devops contains all detailed information.

Automation of processes

Automating as many development, testing, configuration, plus deployment procedures as possible is the fantastic rule of DevOps. It allows professionals to get rid of time-consuming repetitive work and focus on other important activities that can’t be automated by their nature.


Measurement of KPIs (Key Performance Indicators)

Decision-making should be driven by factual data to start with. To find optimal performance, that is necessary to be able to keep track regarding the progress regarding activities composing typically the DevOps flow. Testing various metrics regarding a system permits for understanding precisely what is useful and precisely what can be superior.
