Testing-as-a-service (TaaS) is an outsourcing model wherein software testing activities are done by third-party providers. While some tests may be done in-house, most specialized tests are often outsourced to more capable service providers.

TaaS may involve getting consultants who are well-versed in handling tests by simulating real-world environments, enabling them to find software bugs. But it can also take the form of a pay-as-you-go service.

TaaS is necessary for IT companies with a pressing need to test and inspect their cloud environments and infrastructure to evaluate business performance, operations, and security. Often, the main goal is to find security vulnerabilities inside one’s network to optimize a program’s or service’s overall performance.

What Are the Different Types of TaaS?

Now that you know the answer to “What is TaaS?” you need to understand next that it comes in at least three major types, which are:

Functional Testing-as-a-Service

This TaaS type involves testing the front-facing parts of a website or an application, including the graphical user interface (GUI), to see how target users will interact with it. This test is necessary to let organizations know if their applications do what they are supposed to and if these have bugs that may affect their functionality.

Performance Testing-as-a-Service

In performance TaaS, providers perform “stress tests” on an application to see how well it can handle multiple users. It involves creating virtual users to simulate how the program runs a massive load. The results from this test are crucial in determining how scalable a website or an application is.

Security Testing-as-a-Service

Often considered the most critical TaaS type, security testing mainly scans and probes applications and websites for vulnerabilities. It adds a layer of protection to the programs and makes the developers accountable for user data security.

What Are the Benefits of Testing-as-a-Service?

TaaS offers several advantages for organizations that include:

Reducing Testing Costs

Some organizations may not have the necessary skills and resources to do in-house tests. Often, hiring testers and investing in tools may cost more. When done by experienced and reputable service providers, organizations can benefit from reduced costs.

Hastening the Testing Process

Since TaaS providers are better-skilled and have more resources, they can carry out tests and find potential issues much faster than in-house teams.

Providing Better Perspectives

Organizations can also benefit from unbiased test results. Often, in-house development teams would have biases or develop tunnel vision when looking at their creations. Availing third-party services can give companies a new perspective, allowing them to see issues that they may otherwise miss.

Improving Accountability

Accountability is among the top priorities of doing security TaaS. Third-party providers can test and verify the soundness of clients’ applications and websites’ security, thus reducing potential liabilities should these suffer an unfortunate breach.

When Should TaaS Be Used?

TaaS is best used when:

  • Organizations need to test applications that require extensive automation with only a short test execution cycle.
  • Tasks for testing do not require companies to reveal in-depth information about the system and its design.
  • An organization is only equipped for minimal testing activities, but its application requires extensive knowledge and resources.

What Are the Key Testing-as-a-Service Features?

Some of the primary TaaS features include:

  • A self-service portal that allows applications to run during functional and load tests
  • A test library that comes with security controls and the capability to save test assets
  • On-demand test labs that can be automated to run multitier applications, test scripts, and test tools
  • A metering function that can monitor resource use and testing costs
  • A dashboard for tracking application diagnostics

TaaS has several benefits, but the model may not apply to all business types. After learning the answer to “What is TaaS?” you now have an idea if the model will work for your business or not.
