Companies use the outsourcing approach known as “Testing as a Service” in short “TaaS” to test their products prior to deployment. The application is tested to find flaws in simulated real-world environments. Testing solutions are provided by a third-party service provider with testing knowledge rather than internal employees of the organization.
Prerequisite: Software Testing
Over conventional testing environments, TaaS has been shown to have substantial advantages. TaaS is a highly scalable approach, which is its main advantage. Small businesses and corporations don’t have to worry about finding empty space for servers or other infrastructure because it is a cloud-based delivery strategy.
Features of TaaS
- Test library: Test library with a large set of test cases, and full security controls with configurable parameters that can be used as templates and customized for various user scenarios.
- Metering capability: This allows tracking and charging for the services used by the customers.
- Community-driven: The testing library grows as the vendor and community of users add new test cases thus improving the overall utility of the TaaS platform.
- On-demand availability: On-demand availability for test labs includes the ability to deploy complex multi-tier applications, test scripts, and test tools. It follows a subscription model where instead of investing in dedicated technologies organizations consume the resources as needed on a subscription basis.
- Cloud hardware resource pool: Sharing of the cloud hardware resource pool is facilitated by abiding by security policies to maximize hardware utilization.
- Self-service portal: It provides a self-service portal for running applications for load and functional tests.
- Short turnaround: Multiple tests can be conducted continuously and in parallel which is suitable for the DevOps SDLC pipeline.
- Testing cycle support: In this model, vendors offer end-to-end support that covers planning, implementing, and evaluating software tests.
- External expertise: Finding the right set of technology solutions, designing test cases, and managing infrastructure operations to meet business demands.
Why use TaaS?
Below are some of the reasons for using TaaS:
- Avoid infrastructure cost: TaaS is used when there is a need to avoid overhead infrastructure costs.
- Tests include repetitive tasks: When the tests include repetitive tasks that are otherwise a time drain for in-house employees.
- Lack of skilled personnel: TaaS is beneficial in situations when there is a lack of skilled personnel or resources necessary for testing.
- Need unbiased tester: When there is a need for unbiased testers with limited business domain knowledge then TaaS is a perfect fit.
- Quick testing: TaaS can be used in situations when there is a need to complete quick or special testing outside of the ordinary routine.
How does TaaS Works?
Generally, the company hires a third party to conduct all the testing procedures that are essential for any business model. The organization buys everything from TaaS providers that are required such as testing tools, testing software, and infrastructure. TaaS could seek out one piece of the testing procedure, like a platform, a mix of computer code and infrastructure, or the outsourcing of a whole department. Despite the form TaaS takes, it involves a provider assuming some portion of the organization’s testing responsibilities.
- TaaS could also be used for an automated testing process that might manually take longer for in-house employees to complete manually.
- It may also be utilized in things once the client organization does not have the resources to perform testing themselves.
- The resource could also be time, money, employees, or technology.
- Basically, under the control of TaaS, a scenario and an environment are created to do the test.
- TaaS is not an option for organizations that require highly in-depth knowledge of the company’s infrastructure.
The following activities are involved in TaaS:
- Create user scenario: The user scenario and environment are created to do the test.
- Design test: The test is designed to evaluate the company’s response to the user scenario.
- Execute test: The test is executed in the secure test environment provided by the vendor.
- Monitor performance: The vendor monitors the performance and evaluates the company’s ability to meet the goals specified in the test design.
- Improve system: The vendor and company work together to improve the system or product being tested to improve the future performance of the system.
When to Use TaaS?
TaaS is useful when organizations are in need of the following cases:
- Automation required: Extensive automation is required for testing applications within a limited amount of time.
- No need for in-depth data: A testing task does not need in-depth data on the company’s infrastructure.
- Testing not performed regularly: Testing activities are not performed on a regular basis using extensive resources.
Types of TaaS
- Cloud Testing as a Service: TaaS provider checks all cloud services used by the organizations.
- Functional Testing as a Service: TaaS purposeful Testing could embody UI/GUI Testing, regression, integration, and automatic User Acceptance Testing (UAT) however not necessary to be a part of purposeful testing.
- Load Testing as a Service: TaaS test the estimated volume of the software used.
- Performance Testing as a Service: Multiple users are accessing the appliance at an identical time. TaaS mimic a real-world user setting by making virtual users and playacting the load.
- Quality Assurance Testing as a Service: The vendors ensure a product that meets the company’s requirements.
- Security Testing as a Service: TaaS scans the applications and websites for any vulnerability to check malware and virus attacks.
- Penetration Testing as a Service: TaaS seller tests the company’s security natural virtue against cyber threats by performing mock activity attacks.
Types of Testing Outsourced with TaaS
Different companies or organizations depending upon their need can choose different types of outsourcing from Taas which under the category of functional and non-functional are as follows:-
- Data warehouse testing: It is the process of developing and running detailed test cases to ensure that the data in a warehouse is trustworthy, accurate, and compatible with the organization’s data structure.
- Load Testing: In order to assess if a system, piece of software, or computing equipment can manage high loads given a high demand from end-users, load testing investigates how the system acts under normal and high loads.
- Performance Testing: It is a type of testing that assesses the responsiveness, speed, and stability of a computer, network, software program, or device when subjected to a workload.
- Regression Testing: It is a sort of testing that ensures that changes made to the codebase do not change existing program functioning. These code updates might involve adding resolving problems, new features, or upgrading an existing feature.
- Security Testing: It is a sort of software testing that identifies system vulnerabilities and ensures that the system’s data and resources are secure from potential invaders.
- Acceptance Testing: It is a quality assurance (QA) technique that assesses how well an application meets the approval of end users. Beta testing, field testing, application testing, or end-user testing are all examples of acceptance testing.
TaaS over Cloud
In Cloud, TaaS occurs in the following steps:
- Develop various possible user scenarios.
- Design and validate the various critical test scenarios.
- Select a cloud service provider.
- Establish the needed infrastructure.
- Exploit cloud service.
- Begin the testing.
- Monitor and track the required goals.
- Deliver with high accuracy.

TaaS Use Cases
- A company may hire a vendor to test their existing Disaster Recovery Plan as companies often tend to neglect disaster recovery testing because it does not directly generate revenue, and IT teams often have strict deadlines with other issues like complex IT environments.
- A company may hire a vendor to penetration test its network. The vendor delivers automated testing through a TaaS delivery model that allows end users to view test data in real-time. Users can then use these real-time results and reference a library of remediation instructions to improve security.
