We will learn how to do "Cloud Testing" in this article. To comprehend this, we must first comprehend the Cloud Computing idea. This article discusses Cloud Computing, Cloud Testing, and the key issues associated with cloud testing.

Introduction to Cloud Computing

Several years ago, the industry was introduced to a new term and technology known as "virtualization." With the introduction of virtualization, the idea of sharing computer resources across various operating systems in order to enhance scalability, decrease capital costs, and enable simple management of IT infrastructure, became the backbone of several businesses.

In recent years, IT has seen a virtualized development in the form of cloud computing. Any newcomer to the cloud must envision cloud computing as a concept in which everything is provided "as a service."

It is self-evident that cloud computing is a comprehensive solution that provides IT as a Service. Its slogan, like virtualization, is resource sharing, with on-demand allocation and availability through the Internet.

Cloud Testing

Cloud testing is a form of software testing that involves leveraging cloud computing services to test a software application. The goal of cloud testing is to use cloud computing to test software for both functional and non-functional criteria. This provides quicker availability, scalability, and flexibility, which saves time and money for software testing.

Cloud computing is a web-based platform that provides remote access to computing services such as hardware, software, and other computer related services.

Cloud computing is classified into three types −

  • SaaS is an abbreviation for Software as a Service

  • PaaS is an abbreviation for Platform as a Service.

  • IaaS is an abbreviation for Infrastructure as a Service.

Now let's take a closer look at each of them.

  • Infrastructure as a Service (IaaS) − This is the most basic layer that serves as the foundation for the cloud. Physical resources such as storage, network devices, computer servers, and so on make up the majority of it. All of these computer resources are offered on demand, meaning that a user only pays for what he uses.

  • PaaS (Platform as a Service) − The platform is the most important layer in the cloud. You have no influence over the underlying infrastructure, but you may access the apps that have been deployed. As a result, this delivers a complete run-time environment on demand, which may be a development or testing environment. As a result, under this approach, you would typically have a VM that has a complete environment, such as an operating system, necessary middleware, and so on, ready when needed.

  • SaaS (Software as a Service) − The application layer is the uppermost layer in this case, and it is typically visible to any user. Users can access applications/products on-demand through the internet in this case. As a result, rather than having to buy the license for a specific user, this appears to be the most cost-effective method of ensuring that the license is constantly in use. Gmail, Google Docs, Photoshop, and other applications are examples of this.

Clouds of Different Types

Public, Private, and Hybrid clouds are the three types of cloud formations −

  • Public clouds are those in which services are open to anyone and resources are assigned and provided dynamically in response to requests.

  • Private clouds are often controlled inside the confines of an organization's firewall regulations and are only accessible to employees.

  • Hybrid clouds bring together the advantages of both private and public clouds. Organizations can choose which services they want to make available to the general public and which services they want to make available solely to internal users.

Cloud Testing Methodologies

The entire cloud testing industry is divided into four major groups.

  • Testing of the entire cloud − The cloud is seen as a full thing, and testing is performed based on its features. This sort of testing is being pursued by cloud and SaaS companies, as well as end-users.

  • Testing within a cloud − Testing is carried out by inspecting each of its internal characteristics. This sort of testing can only be performed by cloud suppliers.

  • Testing across cloud − Testing is carried out on various cloud-like private, public, and hybrid clouds.

  • Cloud-based SaaS testing − Functional and non-functional testing is performed based on application requirements.

Ways of doing Cloud Testing

Types of Cloud TestingTask Performed
SaaS or Cloud-oriented Testing − Cloud or SaaS companies are often in charge of this sort of testing. The main goal is to ensure that the service functionalities supplied in a cloud or SaaS application are of high quality. Integration, functional, security, unit, system function validation, and regression testing, as well as performance and scalability assessment, are all conducted in this environment
Online based application testing on a cloud −This testing, which includes performance and functional testing of cloud-based services, is done by online application suppliers. When applications are linked to legacy systems, the quality of the connection between the legacy system and the under test cloud application is evaluated.
Cloud-based application testing over clouds −This sort of testing is used to assess the quality of a cloud-based application across many clouds.

SaaS Testing

SaaS Testing is a software testing method in which the functional and non-functional requirements of a software application created under a Software as a Service model are tested. The aim of SaaS testing is to verify the quality of the software application by evaluating data security, integrity, performance, compatibility, and scalability.

Cloud testing concentrates on the most important elements, such as −

  • Application − Functional testing, end-to-end business operations, data security, browser compatibility, and more are all part of the application.

  • Network − This involves testing different network bandwidths, protocols, and data transport across networks.

  • Infrastructure − This section includes disaster recovery testing, backups, secure connections, and storage regulations. Validation of the infrastructure is required for regulatory compliance.

Other forms of cloud testing include −

  • Performance

  • Availability

  • Compliance

  • Security

  • Scalability

  • Multi-tenancy

  • Upgrade testing in real-time

Cloud Testing Is Necessary

Cloud testing is the testing of on-demand resources such as hardware, software, and so on. Even the testing, in this case, maybe considered as a "service." It is critical for cloud services to ensure that the service (product) not only fulfils functional criteria but also non-functional needs. With a growing number of cloud-based apps, it is becoming increasingly important to create a Cloud Testing strategy.

Advantages of Cloud Testing

The necessity for cloud testing is obvious when we consider the numerous advantages we gain from it. We've sought to outline the most obvious features that illustrate why Cloud is so important right now −

  • Dynamic testing environment availability − In most organizations, the standard testing method is to invest in the hardware and software infrastructure necessary for testing. Many of you would almost certainly agree that the environment provided to testing teams seldom matches a client environment due to frequently changing needs, making it difficult for organizations to stay up. The cloud is the sole solution to this problem since it allows users to quickly duplicate a client environment and detect faults early in the cycle.

  • Low price − Another perspective to the preceding argument is that when businesses invest in infrastructure, the most common reason is that many of their servers are underutilized all of the time. As a result, they may have to spend more money on license renewal. Transitioning to the cloud also helps in this case since users may commission gadgets whenever they want, saving a company a lot of money.

  • Easily customizable − With the use of the cloud, companies can easily imitate an end-user-oriented environment by changing it based on use, saving money and time. Load and performance testing scenarios may be readily performed by test teams in a variety of permutations and combinations, such as different operating systems, browsers, settings, and so on.

  • Scalability − One of the most appealing aspects of the cloud is the option to expand or reduce computer capacity as needed. This is commonly utilized in circumstances when business requirements change regularly.

Cloud-based testing Dive Deep

Testing in the context of the cloud will use both classic and cutting-edge approaches. Both testing and cloud are massive areas in their own right.

In the sections below, we'll look at how to see both at the same time.

  • Cloud Testing Forms Based on what they intend to achieve, cloud testing may be categorized into four main categories −

    • Testing of the entire cloud − The cloud is considered as a full entity with its own set of features, and testing is done accordingly.

    • Testing within a cloud − This is testing that takes place within the cloud itself, evaluating all of its inherent functions.

    • Cloud-to-cloud testing − The testing is done on many types of clouds, such as public, private, and hybrid clouds, based on the specifications.

    • Cloud-based SaaS testing − Functional and non-functional testing is carried out in accordance with the criteria.

  • Cloud Testing Environments Cloud Testing Environments are classified into three types −

    • A private or public environment in which the quality of the apps deployed must be certified.

    • A hybrid environment in which the quality of the apps installed must be verified.

    • A cloud-based testing environment in which the quality of cloud deployed apps must be confirmed.

  • Types of Testing Performed in the Cloud Testing in the cloud must not only verify that functional requirements are satisfied, but it must also place a significant focus on nonfunctional testing. Let's have a look at the many types of testing that are done.
