What Is Cloud Testing

Cloud testing, also known as cloud-based testing, is a form of software testing that assesses the performance, security, scalability, and reliability of web applications on a QA tester’s cloud computing environment. For organizations testing cloud resources, this ensures optimal performance, availability and security of data, and minimizes downtime of the associated infrastructure/platform.

Cloud testing enables easy and quick provisioning of testing environments, eliminating the need of shared test environments. Compared to traditional methods of testing, cloud testing reduces delivery times, improves flexibility, and offers pay-per-use costs. Technologies and test processes used to conduct functional tests for cloud-based applications are not that different from traditional on-premises applications. However, third-party testers know about the non-functional risks associated with cloud systems, and it is a critical success factor.

Business Impact

“The cloud testing market is expected to register a CAGR of over 13% over the forecast period (2021 – 2026). The demand for cloud testing is increasing owing to the capabilities of cloud sourcing technology in software testing activities to perform quality assurance (QA) and to remove bugs.” – Mordor Intelligence 

According to Emergen Research, the global cloud testing market size is expected to reach USD 21.67 Billion in 2028 and register a robust revenue CAGR of 12.8% throughout the forecast period.

Technological advancements such as edge computing, 5G, real time analytics using ML and AI, and preference for on-demand services will drive revenue growth. With the adoption of DevOps, the cloud testing market is achieving rapid growth.

Enterprises adopting cloud-based testing can benefit in the following aspects.

  • Cost efficiency:  There is zero investment and no additional maintenance costs for the application. The pay-per-use model and on-demand availability of cloud-based testing tools eliminates the investment costs of purchasing, maintaining, and upgrading the software/hardware.
  • Scalability: Cloud testing offers flexibility to enterprises. Testers can increase/decrease computing resources fast, thus addressing the dynamic needs of the customers quickly.
  • Test environment: It takes time to set up an ideal test environment on all the devices. Moreover, configuration errors can repeat on all devices. Cloud-based tools are preconfigured by the service providers that saves time and money. To achieve best results, enterprises can use customized tools by combining multiple test environments.
  • Increases efficiency: Cloud testing reduces the time to set up a test environment from weeks to minutes and lowers the quality risks.

Types of Cloud Testing

While the term cloud testing broadly refers to testing applications through cloud computing resources, the main types of cloud testing:

Functional Testing

It verifies and validates the functionalities of a software application.

  • System Testing — Evaluate requirements & functionalities for end-to-end application development
  • Acceptance Testing — This technique ensures that the software is ready to use.

Non-functional Testing

It ensures delivery of non-functional aspects like performance, usability, reliability, and response time.

  • Security Testing- This type of testing checks for six major principles – Authorization, Availability, Authentication, Confidentiality, Integrity, and Non-repudiation.
  • Scalability and Performance Testing – It helps understanding the system behavior for a certain expected load.
  • Compatibility Testing- It checks for compatibility with various cloud environments and instances of different OS.
  • Disaster Recovery Testing- It evaluates the response time and ensures that the application is recovered quickly with minimum loss of data.
  • Multi-Tenancy Testing – In this type of testing, a single instance runs on the primary server and multiple tenants. The test environment aims at allocating a fixed share of the instance to every tenant including individual functionality, data, user management, configuration, and other non-functional properties.
