Real Time Automation Interview Questions - Part 4

  • Have you used GIT in your project, can you explain about it?
    • Yes I have used GIT, It is a version control tool. Where we can maintain our central repo. we used to manage our code via GIT only. 
    • We use Git to maintain our project in our local system. So, if someone like to work on that project I need to send complete update copy to him and after that he can work on that. 
    • There are chances that single project is handled by multiple teams across the globe. So, it will be difficult if we won’t use GIT.
  • Can you give me some GIT commands which you use daily?
    • Git status- which shows status of all the files,if we have some files which is not yet added to our repo so it will give us untracked file. 
    • After that we can use GIT add command after adding it will added to particular index and we can commit this file using Git Commit -m(Message) we can commit this untracked file. Also we have Git Merge, Git Push, Git Pull, Git checkout in etc
  • How to solve merge conflict in GIT?
    • As we are only 2 tester working on this project, if we have any merge conflict I used to pull all the latest file/scripts to my local system. 
    • Then I will analyze the difference between that particular file and merge file. After that I will check with my team member whether all his imp things are covered then I will add my steps and push the script to the central repo.
  • Have you worked in Jenkins? Can you tell me how to create jobs in Jenkins?
    • We have separate Dev-Ops Team to create Jenkins jobs at broad level but we also have access to jenkins, so we have created jobs for our internal purpose. 
    •  For creating any job we have click on create new job->inside that give name of your job->select freestyle project->then add. Beside that we can provide description of our project and in source code management we can choose Git-> provide repo url ->after that provide some schedule if you want to run the job on any specific schedule time.-> select window batch command-file location-save-click on build now for running. After triggering we can check log in console
  • What is the difference between smoke and sanity testing?
    • Smoke and Sanity we can think like a same thing because both are checking important functionality. 
    • Smoke testing is done on first stable build from developer to check like whether it is stable enough to move further or not. 
    • While Sanity testing is subset of regression test which we perform on stable build and here also we used to check all the imp functionality.
  • What is Agile ceremony?
    • We have 4 Agile ceremony(events that occur during a Scrum sprint) - 
    • Sprint planning  
    • Sprint review 
    • Sprint Retrospective  
    • Daily scrum meeting.
  • Why the main method is static?
    • Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class. 
    • Static method of a class can be called by using the class name only without creating an object of a class. 
  • What is Run time Polymorphism?
    • Run-Time Polymorphism: Whenever an object is bound with the functionality at run time, this is known as runtime polymorphism. 
    • The runtime polymorphism can be achieved by method overriding. Java virtual machine determines the proper method to call at the runtime, not at the compile time.
  • Difference between list and set?
  • What is method overloading and overriding?
    • Method overriding is used to provide the specific implementation of the method that is already provided by its super class.  
    • Method overloading is performed within class.
    • Method overriding occurs in two classes that have IS-A (inheritance) relationship. 
    • In case of method overloading, parameter must be different

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 ...
