What is Testing as a Service?

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.
