What is TaaS (Testing as a Service): What, Why, and When to Implement

What is TaaS (Testing as a Service): What, Why, and When to Implement
April 4, 2024


When it comes to developing new software solutions, there's a perilous edge to cutting corners. We've all heard tales of software projects gone awry, where testing was sacrificed on the altar of tight deadlines and soaring ambitions. The consequences? Software glitches, security breaches, and customer frustration. The first example that pops up in our mind is probably the infamous "Mars Climate Orbiter".

In 1999, NASA's Mars Climate Orbiter mission ended in a fiery disaster. The spacecraft, designed to study the Martian climate, was lost in space. The reason? A simple oversight in the software code. Engineers failed to convert units from imperial to metric, a seemingly trivial error that resulted in the spacecraft burning up in the Martian atmosphere. It was a costly mistake (only the craft itself cost USD 125M+), both in terms of money and scientific progress.

The Mars Climate Orbiter saga serves as a stark reminder of the paramount importance of software testing — neglecting it can have catastrophic consequences. Yet, we don't have to rely solely on cautionary tales to understand the significance of TaaS. Real-world studies and experiments further underscore its importance. The National Institute of Standards and Technology (NIST) found that software bugs cost the U.S. economy an astonishing USD 59.5 billion annually. These figures are another stark reminder that the ramifications of inadequate testing reverberate far beyond the confines of a development team.

Understanding TaaS (Testing as a Service)

TaaS is an acronym for testing as a service, and it is always performed by an outside contractor. That is, you develop a certain software, and a subcontractor tests it. This way you save your own resources and, if the contractor is skillful enough, you also insure yourself against potential failures.

What is Testing as a Service?


Indeed, TaaS emerges as a pivotal player. But what is TaaS technology? As we said before, TaaS is a model where testing is outsourced to a specialized provider. It’s like having your own team of testing experts on call, without the hassle of hiring and managing an in-house QA team.

Most often this means you’ll have a range of testing services, including functional, performance, security, and compatibility testing. What makes it intriguing is its scalability. Whether you're a startup or an established enterprise, TaaS adapts to your needs. The benefits are clear: access to a broader spectrum of testing expertise, reduced overheads, and the flexibility to scale your testing efforts as your projects evolve.

Traditional vs. TaaS Services

When it comes to software testing, choices abound. Two prominent players in the field are traditional in-house testing and software testing as a service. To help you navigate this decision, let's compare these approaches in a head-to-head showdown. Below, we present a comparative table highlighting the key differences between Traditional Testing and TaaS Services. Whether you're a startup, an established corporation, or something in between, this table could be your compass.


Types of Testing Offered Through TaaS

When you embark on the journey of test service, you gain access to a diverse array of testing types that cater to the intricate landscape of software development. In general, there are two broad groups of tests: functional and non-functional. It’s possible you can find another ramification, but we go further with this one as more clear-cut.


Functional Testing in TaaS

Functional testing forms the bedrock of software evaluation. TaaS extends this fundamental practice with a suite of testing types:

Unit Testing: At the foundational level, Unit Testing scrutinizes individual components or units of your software. It ensures that each part functions correctly in isolation, identifying any code-level defects. Think of this as checking the vital signs of individual parts of your software. It ensures that each piece works correctly on its own, making sure there are no code-level hiccups.

Integration Testing: As your software becomes more complex, Integration Testing checks how different parts work together. It's like ensuring that a puzzle's pieces fit snugly.

System Testing: This one examines the entire software system, making sure that everything plays well together. It's like the final dress rehearsal before a big performance.

Acceptance Testing: The ultimate litmus test, Acceptance Testing, ensures that your software aligns with user expectations. It assesses whether the software meets the acceptance criteria, validating its readiness for deployment.

Non-functional Testing in TaaS

From the text above, it might seem that functional tests are more important than others. After all, they check the software capability. And such tests are indeed important, but not more important than non-functional ones. TaaS offers an array of non-functional testing types to address these vital considerations:

Security Testing: Just recall a recent Okta breach to understand how security is important. TaaS providers rigorously assess your software's vulnerabilities, identifying and mitigating security risks.

Performance Testing: To ensure that your software can handle the stress of real-world usage, Performance Testing evaluates its responsiveness, scalability, and stability under different conditions.

Usability Testing: The user experience is the star here. Usability Testing ensures your software is user-friendly, making sure it's a pleasure (or, let’s face it, even addiction) to use.

Compatibility Testing: In the diverse world of devices and browsers, Compatibility Testing ensures that your software functions seamlessly across platforms, making it accessible to a wider audience.
