Indeed, a global survey of IT executives reveals that over half of the respondents view software testing cost as their biggest challenge. No wonder, companies increasingly look for solutions to reduce these costs without sacrificing quality.
In this article, we’ll discuss software testing cost in detail, from its key drivers and estimated amounts to effective ways to cut expenses wisely.
Let’s dive right in!
4 Common Cost Drivers In Software Testing
A 2019 survey of CIOs and senior technology professionals found that software testing can consume between 15% and 25% of a project’s budget, with the average cost hovering around 23%.
So, what drives these substantial costs in software testing? Read on to find out.
4 Common Cost Drivers In Software Testing
Project complexity
First and foremost, the complexity of a software project is a key determinant of testing costs.
Clearly, simple projects may require only minimal testing, whereas complex, multifaceted applications demand more extensive testing efforts. This is due to the fact that complex projects usually feature intricate codebases, numerous integration points, and a wide range of functionalities.
Testing methodology
The chosen testing methodology also plays a big role in defining testing costs.
Various methodologies, such as functional testing, non-functional testing, manual, and automated testing, carry different cost implications.
Automated testing, while efficient, requires an upfront investment in tools and scripting but can save time and resources in the long run since it can quickly and accurately execute repetitive test cases.
On the other hand, manual testing might be more cost-effective for smaller projects with limited testing requirements, yet may still incur ongoing expenses.

How To Reduce Software Testing Costs?
Since many companies are questioning how to reduce the cost of software testing, we’ve compiled a list of top 8 practical best practices to help minimize these costs without compromising quality and results. Check them out below!
How To Reduce Software Testing Costs?
Embrace early and frequent testing
Testing should be an ongoing task throughout the development phase, not just at the project’s end.
Early and frequent testing helps companies detect and resolve bugs efficiently before they escalate into serious issues later on. Plus, post-release bugs are more detrimental and costly to fix, so addressing them early helps maintain code quality and control expenses.
Prioritize test automation
Test automation utilizes specialized software to execute test cases automatically, reducing the reliance on manual testing.
In fact, according to Venture Beat, 97% of software companies have already employed some level of automated testing to streamline repetitive, time-consuming QA tasks.
Although implementing test automation involves initial costs for tool selection, script development, and training, it ultimately leads to significant time and cost savings in the long term, particularly in projects requiring frequent updates or regression testing.
Apply test-driven development
Test-driven development (TDD) refers to writing unit tests before coding. This proactive approach helps identify and address functionality issues early in the development process.
TDD offers several benefits, including cleaner code refactoring, stronger documentation, less debugging rework, improved code readability, and better architecture. Collectively, these advantages help reduce costs and enhance efficiency.
Consider risk-based testing
Risk-based testing prioritizes testing activities based on the risk of failure and the importance of each function.
By focusing on high-risk areas, this approach simplifies test planning and preparation according to the possibility of risks, which not only improves productivity but also makes the testing process more cost-effective.
Implement continuous testing and DevOps
DevOps focuses on combining development and operations, with testing embedded throughout the software development life cycle (SDLC).
When integrating testing into the DevOps pipeline like that, businesses can automate and execute tests continuously as new code is developed and integrated, thereby minimizing the need for expensive post-development testing phases.
Use modern tools for UI testing
Automating visual regression testing with modern, low-code solutions is an effective approach for UI testing.
These tools harness advanced image comparison, analyze and verify document object model (DOM) structure, on-page elements, and handle timeouts automatically. Thus, they allow for rapid UI tests – often in under five minutes – without requiring extensive coding.
In the long run, this practice saves considerable resources, reduces communication gaps among developers, analysts, testers, and enhances the development process’ overall efficiency.
Account for hidden costs
Despite efforts to manage and reduce software testing expenses, unexpected hidden costs can still arise.
For instance, software products with unique functionalities often require specialized testing tools and techniques. In such instances, QA teams may need to acquire new tools or learn specific methodologies, which can incur additional expenses.
Infrastructure costs can also contribute to hidden costs, including fees for paid and open-source software used in automated testing, as well as charges for cloud services, databases, and servers.
Furthermore, updates to testing tools might cause issues with existing code, necessitating extra time and resources from QA engineers.
Outsource software testers
For companies lacking the necessary personnel, skills, time, or resources for effective in-house testing, outsourcing is a viable alternative.
Outsourcing enables access to a broader pool of skilled testers, specialized expertise, and cost efficiencies, particularly in regions with lower labor costs, such as Vietnam.
However, it’s important for businesses to carefully evaluate potential outsourcing partners, establish clear communication channels, and define service-level agreements (SLAs) to ensure the quality of testing services.
