Testing as a Service (TaaS): Understanding Automated Testing in the Cloud

Hari Mahesh

Software development is undergoing tremendous change and advancements. Compared to traditional software development, the application architecture has become more complex, and application releases have become more frequent and demanding. Also, ensuring the quality and reliability of the application becomes a greater concern. So, in this situation, we can’t rely on traditional testing methods. This led to the rise of a new concept: Testing as a Service (TaaS).

TaaS is a cloud-based model that provides testing solutions. It offers a flexible, scalable, and cost-effective way to ensure high quality for the application under test (AUT). So, let’s understand in more detail the benefits of TaaS and how it helps the testing industry achieve its vision.

What is Testing as a Service?

Testing as a Service, or TaaS, is a cloud-based model that provides on-demand testing services. Many organizations won’t have enough resources or won’t be able to bear the cost of having a larger testing team. So, in those cases, they will be outsourcing their testing requirements to third-party service providers who offer testing solutions over the cloud. The testing solutions offered can be a suite of services, including functional testing, performance testing, security testing, and more.

Key Components of TaaS

There are four key components of TaaS. Let’s go through each of them.

• Cloud Infrastructure: TaaS relies on cloud infrastructure to provide testing environments. The advantage is these environments are scalable and flexible. So, using cloud infrastructure eliminates the need for organizations to invest money and resources in buying and setting up hardware and software for testing purposes. Read: Cloud Testing Guide: Needs, Examples, Tools, and Benefits.
• Automated Testing Tools: the third-party vendors who provide TaaS utilize a range of automated testing tools to perform various types of tests. These tools can be configured to run tests continuously, ensuring that software is always up-to-date and free of defects.
• Service Level Agreements (SLAs): SLAs are kept between the organization and vendors who provide TaaS. So, these SLAs define the scope, quality, and timelines of the testing services offered. Also, these SLAs ensure that organizations receive a consistent and reliable level of service.
• Reporting and Analytics: TaaS usually includes comprehensive reporting and analytical tools. These tools help to understand in-depth details about the test results and the stability of the application. Also, for any failures, it will be more easy to identify the root cause of the issue and rectify it.

Benefits of TaaS

There are many advantages of using TaaS. So, let’s go through the benefits.

Cost Efficiency

One of the primary benefits of TaaS is cost efficiency. Maintaining an in-house testing infrastructure involves high costs. This cost is mainly related to hardware, software licenses, and personnel. So, this cost can be avoided by outsourcing the testing to a third-party TaaS provider. While using TaaS, the organizations need to pay only for the testing service they use, thereby making it a cost-effective solution. This is more advantageous for smaller organizations and start-ups, where they need more testing requirements during release time and can’t spare more money to increase the size and infrastructure of the testing team.

Scalability

Since TaaS is based on cloud-based testing, you can scale up or scale down the testing environments based on the project’s needs. This provides TaaS with outstanding scalability. So when there is any change in testing requirements, like release testing, where we need more extensive testing and need to do different types of testing, the organizations can quickly respond to the changes. This helps to remove the delay due to resource constraints, as with traditional testing models.

Access to Expertise

Organizations that follow traditional testing methods often find it difficult to upskill their employees. The team may not be aware of the latest testing tools. So, we can overcome this limitation by outsourcing to TaaS providers, as they will have a team of experienced testers and access to the latest testing tools and technologies. This helps the organizations to use advanced testing technologies/tools in their project, which may not be available in-house. TaaS providers will have the latest tools and technology and also be up-to-date with the latest trends in the QA field as they need to stay on top of the market. Also, this helps ensure that the test process is efficient and effective.

Faster Time to Market

Automated testing in the cloud can significantly speed up the testing process. Continuous integration and continuous deployment (CI/CD) pipelines can be integrated with automated testing tools to ensure that tests are run automatically whenever new code is committed.
