Last Updated: 21 January 2021

Testing as a Service (TaaS)

Testing as a Service (TaaS) is an outsourcing model, in which software testing is carried out by a third party service provider rather than employees of the organization. In TaaS, testing is done by a service provider that specializes in simulating real-world testing environments and finding bugs in the software product.

TaaS is used when

A company lacks the skills or resources to carry out testing internally
Don't want the in-house developers to influence the results of the testing process (which they could if done internally)
Save on Cost
Increase the speed of test execution and reduce software development time.

Types of TaaS

Functional Testing as a Service: TaaS Functional Testing may include UI/GUI Testing, regression, integration and automated User Acceptance Testing (UAT) but not necessary to be part of functional testing
Performance Testing as a Service: Multiple users are accessing the application at the same time. TaaS mimic as a real-world users environment by creating virtual users and performing the load and stress test
Security Testing as a Service: TaaS scans the applications and websites for any vulnerability

Key TaaS Features

Software Testing as a Service over Cloud

Once user scenarios are created, and the test is designed, these service providers deliver servers to generate virtual traffic across the globe.

In Cloud, software testing occurs in following steps

Develop users scenarios
Design test cases
A select cloud service provider
Set up infrastructure
Leverage cloud service
Start testing
Monitor goals
Deliver

When to use TaaS

TaaS is useful when

Testing of applications that require extensive automation and with short test execution cycle.
Performing a testing task that doesn't ask for in-depth knowledge of the design or the system
For ad-hoc or irregular testing activities that require extensive resources.

Benefits of Cloud Testing

Flexible Test Execution and Test Assets
Some users claim 40-60% savings in the cloud testing vs. the traditional testing model
Achieve a fast return of investments by eliminating the investment made after hardware procurement, management, and maintenance, software licensing, etc.
Deliver product in quicker time through rapid procurement, project set-up, and execution
Ensure data integrity and anytime anywhere accessibility
Reduce operational costs, maintenance costs, and investments
Pay as you use
