Real Time Automation Interview Questions - Part 1

  • What do you mean by wrapper class and how will you do data conversion?

    • Wrapper class in java are used for data conversion. In data

      conversion if user wants to convert Int to string, String to int,

      Boolean, double then we use Wrapper class.

      Integer.parseInt(); -To convert string to Integer

      Double.parseDouble(); -To convert string to Double

      Boolean.parseBoolean(); -To convert string to Boolean

      String.valueof(); -To convert Integer to String

  • Can you convert String = "110a" in integer?

    • No we got NumberFormatException while converting

      the above string.

  • What do you mean by Call by Value and call by Reference in Java?
    • Call by value means suppose we have created one
      sum method with input parameter int a, int b. So
      while calling the creating the object and running we
      provide values that is know as call by value.
  • What do you mean by Exceptions in Java?
    • Exception is like any interruption in our normal flow.
      Like if we are running anything and we got issues in
      our script this is we called exception,
      we have 2 types of exception Run Time & Compile
      Time.(checked & Unchecked exceptions)
  • Can you tell me the difference between Throw and throws keyword?

    • Throw is a keyword used inside a body of function. And Throws used while

      initializing any method. By using Throw we can throw only one exception

      while for Throws we can declare multiple exceptions which might occur in

      that particular function.

      Java throw keyword is used to explicitly throw an exception.

      Java throws keyword is used to declare an exception..

  • How much you rate yourself in Selenium out of 5?
    • 3.5
  • Which locator you are using in your framework and why?

    • Mostly we used ID and Xpath because Id is the

      fastest and unique one and after that we prefer

      Xpath. Anyways we have other locators as well like

      css, class name, tag name, Link text, Partial Link

      text.

  • What is the difference between findelement and findelements?

    • findelement will give the first appearance of that element

      which matches our locator, whereas findelements will

      give us list of all the elements which is present over the

      webpage and matching our locator.

      And if we don’t find the element findelement will give us

      nosuchelementexception whereas findelements will

      return NULL/Empty list.

  • Can you tell me how will you handle multiple windows in Selenium?

    • We have windowhandle & windowhandles function for

      handling Multiple windows. Windowhandle will give the

      string value of only the active window that is open

      whereas windowhandles will give set of all the windows

      that are open in browser.

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 ...
