Learn about Cloud Testing

Cloud Testing is a type of testing in which the application is tested using cloud computing services. The purpose of this testing is to test the application for functional as well as non-functional requirements using cloud computing, which makes sure faster availability with scalability and flexibility to save time and cost for software testing. 

Cloud Delivery Models

SaaS (Software As A Service)

It is the topmost layer of the cloud—the end-users experience the applications on-demand over the internet. The cloud gives access to various applications for deployment, development, and performing other useful tasks like working on word online, excel, Email, ERP tools, etc.

IaaS (Infrastructure As A Service)

The feature that the cloud offers is IaaS, which facilitates the use of machine resources in the cloud. You can configure the machine according to the need of the vast marketplace. You can select a machine image type from Ubuntu, Amazon, Microsoft, etc.. You can add CPU in batch for fulfilling your utilization, choose solid-state device memory based on the data input-output speed. So go for the right one because this architecture would be the efficiency pillar of your organization. 

PaaS (Platform As A Service)

Cloud provides a platform for configuring, writing, and deploying your code directly. You do not have to worry about the machine. Cloud automatically manages your device, no matter which language, for example, PHP, or Python, your code is written. You have to select the right one. For example, AWS provides a lightsail service that you can deploy to host your website in any language.

Need for Cloud Testing

It can help in unearthing issues for the betterment of the product. In today’s competitive times, companies have to leverage cloud technologies to save on infrastructure costs. Cloud-based testing is one method that can accelerate the testing process and also reduce the costs of maintaining the infrastructure.

Benefits of Cloud Testing

  • Cost-Effective
  • Consistent Development Tools Setup for the Existing and New Staff
  • 24 Hour Access to the Resources
  • Consistent Development Tools Setup for the Existing and New Staff

Type of Testing in Cloud

The whole cloud testing is divided into four categories

  • Testing the entire cloud: The cloud is viewed as an entire entity and based on its features testing. Cloud and SaaS vendors, as well as end-users, are interested in carrying out this type of testing
  • Testing within a cloud: By verifying each of its features, testing is carried out. Only cloud vendors perform this testing
  • Testing across cloud: Testing is done on different types of cloud-like private, public and hybrid clouds
  • SaaS testing in the cloud: Functional and non-functional testing is carried out based on application requirements

Process of Cloud testing

  1. Validate the requirements of the application under the test system.
  2. Check the browser compatibility in a cloud environment.
  3. Identify the defects that might arise while connecting to a cloud.
  4. Any incomplete data on the cloud must not be transferred.
  5. Verify that the application that works across a different platform of the cloud.

Challenges in Cloud Testing

Challenge 1: Data Security and Privacy

Cloud applications being a multi-tenant in nature, the risk of data theft always remains. As a cloud testing strategy, users must be given assurance about their data’s safety by suppliers.

Challenge 2: Short notice period

Cloud providers give a short notice period to the customers about upgrades. This is a problem when manually validating the changes to your SaaS application.

Challenge 3: Validating interface compatibility

With an upgrade in the Cloud service provider, the external interface is also upgraded, which is a challenge for some subscribers used to the older interface. Cloud subscribers ensure that the users can choose the interface version they wanted to work on.

Challenge 4: Data Migration

Data migration from one provider to another is a huge challenge as both providers may have different database schemas. It requires an effort to understand the data fields, relationships, and mapped across SaaS applications.

Challenge 5: Enterprise Application Integration

Enterprise application requires data integration validation of both outbound and inbound data, from client network to SaaS application. Data privacy calls for a specific guarantee to ensure subscribers about the security and confidentiality of data.

Challenge 6: Simulating live upgrade testing

The biggest challenge is to ensure that live upgrades do not impact the existing connected SaaS users.

PROS

  • The testing environment is dynamic. The nature of cloud-based testing is a big draw for organizations that need fast turnaround time and don’t mind self-service. Most cloud testing applications work on a subscription model.
  • The services are secure and affordable. Testing is performed in either public, hybrid or private clouds. The public cloud is a cost-effective choice, and an acceptable level of security is maintained. 
  • You can scale as needed. The scalability of cloud-based testing allows you to ramp up and down as your needs change or your project goals shift.
  • It allows for disaster recovery. In the cloud, the recovery of assets is quick and easy, not laborious or complex.

CONS

  • Bandwidth issues. To maximize the cloud-based testing tool’s effectiveness, you’ll need to have a suitable amount of bandwidth. Because many other organizations share the cloud’s resources, demand will always fluctuate.
  • Redundant tests. Cloud servers are not backed up, which means there is no monitoring of duplicate test plans.
  • Loss of autonomy and security. When you are a subscriber to a cloud-based testing application, you hand over the data and information to an outside party. Though your data will remain safe and confidential in most cases, it is a point to be wary of.
  • Spotty feature coverage. Is your application rich in features? Do you add new functionality constantly.

FAQs

What are the components of cloud testing? 

Application: It covers testing functions, data security, end-to-end business workflows, browser compatibility, etc.
Network: It includes testing of various network bandwidths, protocols, and successful transfer of data through networks.
Infrastructure: It covers disaster recovery tests, secure connection, backups, and storage policies.

What do you mean by Software as Service(SaaS)?

It is a software testing process in which the application built in a Software as a Service model is tested for the functional and non-functional requirements. SaaS testing aims to ensure quality by testing data security, integrity, performance, compatibility, and scalability of the software application.
