testing as a Service

Taas stands for testing as a service, is an outsourcing model in which software testing is carried out by a third-party service provider rather than by staff members of the organization. Taas may simply involve outsourcing some testing to a service provider, or it may require hiring consultants to help and counsel staff members. Usually, a business will carry out some testing internally.

Taas is best suited for specialized testing efforts that do not necessitate extensive knowledge of the design or system. Taas is also known as on-demand testing. Automated regression, performance, security, application, ERP and software and monitoring testing for cloud-based applications are all good candidates for the Taas model.

Taas is using when:

  • A company lacks the necessary skills and resources to conduct internal testing.
  • Reduce software development time and costs by increasing the speed of test execution.
  • Don’t want in-house developers to have a say in the testing process (which they could if done internally)

What basically is testing as a service (Taas) and how does it work?

Taas, or Testing as a Service, is a business model in which companies outsource software testing of their products to testing operations firms. Alternatively, you could offer testing as a service.

While there are numerous reasons to choose Taas, the main benefit is that it allows businesses to focus on other important aspects of their business, such as improving their products or services, researching new products, or planning their marketing and sales targets, rather than spending time on repetitive tasks like software testing.

Scalability is another important element of TaaS. If you were a small company with a limited budget in the early days of software development, you would have had to forgo software testing entirely. However, regardless of your company’s size, you can also subscribe to the service model that best fits your budget.

Testing as a Service perform by both humans and machines. Manual testers, also known as Quality Assurance (QA) analysts, go through a series of step-by-step procedures to find bugs in your application’s key features. In automated testing, however, tools and scripts are used to perform the testing for you. Naturally, automated testing is more efficient and faster.

It is important to note, however, that pitting one type of testing against the other would be incorrect. After all, you need people to write those automated scripts for you. It is also imprudent to complete all testing work manually, as much repetitive work can be automated, but you or your organization may miss the uniqueness that a human tester can provide.

The best approach is to use a combination of manual and automated testing.

Classification of Testing as a Service (Taas)

Taas is classified into two categories functional and non-functional testing.  It refers to a wide range of functional and non-functional testing techniques. It enables businesses to benefit from the comprehensive and personalized support of an experienced testing team when developing and executing software testing and scaling up their technological skills.

Functional Testing in TaaS

The features and functions of an application are tested as part of functional testing. The testing team examines whether the software or application performs as expected by the developer. The tester ensures that the application responds flawlessly to input and produces the expected results.

Some examples include system testing, unit testing, user acceptance testing, and other functional testing techniques.

Non-Functional Testing in Taas

The performance, usability, and security of the application are the main topics of non-functional testing. Vendors go through procedures to ensure that the application is compatible with other software systems, user-friendly, and meets stringent security standards. The application is run in a simulate production environment to test its latency and responsiveness to a predefined workload.

Examples include load testing, compatibility testing, usability testing, scalability testing, and other non-functional testing methods.

Features of testing as a service (Taas)

A Taas platform may have the following features:

  • A Saas portal for running tests and accessing test data.
  • Application diagnostics and monitoring for the tested application.
  • Automated test labs that are available on demand.
  • To reduce resource contention, shared hardware is used.
  • A metering function for tracking resource usage and costs.
  • A test library with user scenario descriptions and configurable parameters.

Various Taas types cater to various needs that arise during a product’s testing phase. You can even select multiple testing services based on your needs.

Performance Taas

The stability, speed, and responsiveness of software are all tested during performance testing. It is completed by simulating a real-world environment through the use of virtual users and the execution of various tests such as soak testing, spike testing, stress testing, and others.

Security/ Penetration Taas

Security testing is software testing that makes sure a program is safe and does not leave any gaps that unauthorized users can exploit. The service provider, such as MicroGenesis, carefully examines your software during security software testing to find any potential holes. If there are any flaws in the system, the QAs will work to correct them.

Regression Testing as a Service:

Regression testing is done to ensure that changing the initial code or adding new functionality does not harm the application. It also checks to see if the new changes have resolved the previous issue. Even minor changes can result in unexpected crashes; regression testing is a method for determining whether or not this is the case.

Disaster Recovery Taas

The ability of the business to respond to and recover from a disaster is assessed by the analysts in the disaster recovery plan.

Unit Taas

Unit testing ensures that each component of the software works properly and meets the requirements. It is typically perform early in the development process before the code is assembled and tested as a whole system.

Unit tests are design to test the smallest piece of code possible, such as a function or method, in isolation from the rest of the system.

Cloud Taas

Cloud testing is a type of software testing that makes use of cloud computing services to test software applications. It is a method of testing software against functional and non-functional requirements. The testing is carried out using SaaS cloud service apps. It makes use of cloud computing services to make the software more accessible, scalable, and adaptable. The testing software saves time and money.

Benefits of testing as a service

The primary benefits of outsourcing or using any service, including testing, are similar. They are focuse on the fact that the paying organization is relieved of the responsibility of hosting and maintaining the technology and testing procedures.

Some of the significant advantages of TaaS include:

Fast Delivery

TaaS vendors buy, set up, and execute projects quickly to deliver the required product ahead of schedule.

Reduced Costs

Employees and infrastructure should not be paid for by organizations. There is no license fee or staff fee.

Less-biased Testers

A third party with restricted information about the product or business conducts the testing. Internal employees are not involve.

Quicker Returns

Organizations can quickly recover their investments in TaaS by completely removing investments in maintenance, software licensing, and so on.

High Handiness

TaaS providers typically provide 24-hour support.


Companies will only make changes to their service agreements if they see fit.


TaaS solutions will also customize to the size of the company.

Pay-as-you-go Valuation

Corporations only pay for the services they use.

The world of technology, including development models such as Agile and DevOps, is constantly evolving. Similarly, software testing methods are evolving. Companies are expect to review and select the right testing techniques to optimize their resources and product to meet the high expectations set by users.

Here are a few examples of TaaS techniques use in the industry:

  • Testing in an Agile Environment
  • Testing Automation
  • Testing continuously
  • Testing of documentation
  • Testing for user acceptance
  • Testing in three modes: black box, grey box and White box
  • Cross-browser evaluation
  • Dynamic evaluation
  • Testing based on risk
  • Exploratory and ad hoc testing

When Should You Consider Using Testing as a Service (Taas)?

Testing as a Service is a model of outsourcing. It is prefer, like any outsourced service, when the costs of performing those activities yourself are higher than simply outsourcing the entire thing.  While cost reduction is an important factor in outsourcing, it is not the only one. Here are a few more factors that make TaaS preferable to traditional software testing.


Spending resources on testing can be a major distraction for a company that focuses on developing its products. This isn’t meant to say that testing should be taken lightly; on the contrary, it should be taken very seriously. Rather than forcing developers to work on testing (along with developing the product) or hiring and establishing a new testing department, it is far better to hire another company that specializes in providing testing services.

Lack of Testing Infrastructure:

Most new businesses lack the resources required to conduct testing. This covers server costs, hardware infrastructure, and software testing, among other things.   

For Improving the Testing Standards

The way you handle testing for your products can have an impact on the outcome of the results. Hiring a professional testing firm can also improve the efficiency of your testing process, making your applications more bug-free and robust.


To summarize, Testing as a Service (TaaS) is a beneficial outsourcing structure in which businesses outsource software testing to specialist testing operations firms. TaaS has multiple advantages, including the freedom for businesses to focus on core activities, scalability to meet a variety of budgets, and access to a trained testing team without the requirement for in-house knowledge. TaaS testing includes both functional and non-functional testing to ensure that applications run as intended, are secure, and fulfill user expectations. The strategy of integrating manual and automated testing ensures that testing processes are efficient and complete. Companies may manage their resources, increase product quality, and fulfill the high expectations of users in today’s dynamic technology landscape by utilizing various TaaS strategies. Overall, TaaS is a cost-effective, flexible, and expert-driven solution for enterprises in need of dependable and thorough software testing services.
