Rest Assured series - Introduction

-

In this article we will cover Rest Assured Introduction. If you are working at backend automation, Rest Assured is the framework and library you might be using to automate your APIs. After Selenium, it is perhaps the most popular library ever used. It comes handy with a lot of features and inbuilt libraries to automate your application backend.

Rest Assured Automation 

Rest Assured was founded by Johan Haleby. It is contributed by many people over the years. Rest Assured is sponsored by Parkster.

We will discuss about Rest Assured Components and Features.
  1. Requests - HTTP requests can be sent by the help of RequestSpecification.
  2. Responses
  3. JSON Schema Validation
  4. Status code validations
  5. Body validation

Advantages of Rest Assured

  1. Less code is written
  2. BDD like code-style
  3. Easy CI/CD Integration

Interview Questions

  • What is the difference between Path Parameter and query parameter?
    • Path parameter is also called as URI parameter. It is used to identify specific resource.
    • Query parameter is used to filter/ sort resources.
    • Consider below example for the reference
Suppose you need to retrieve the record of an employee whose id is 15, In this we can use the concept of Path parameter

GET /employee/{id}

Now another use case is you need to retrieve the list of employees but only 10 at a time, in this case, we can use the concept of Query Parameter as shown below -

GET /employee?start=1&size=10

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 ...
