It’s 2025, yet many organisations still develop bespoke test automation harnesses and frameworks, stitching together a modular in-house automation solution. This is due to various invalid assumptions and short-sighted commercial decisions.
It baffles me, but some people genuinely believe they’ll save money, increase coverage, and create a better automation solution than they’d get with a professional tool, built by dedicated developers and with enterprise-grade support.
Well, here’s a little secret… the chances of successfully achieving this are so slim that we might as well call them zero.
Test Automation Framework: A Quick Definition
For simplicity’s sake, in this article, I will use the blanket term framework to refer to both custom automation frameworks (structured platforms for organising, executing, and reporting automated tests) and test automation harnesses (a collection of tools, stubs, and drivers to facilitate automated testing).
The key point is that they are in-house automation testing setups, often leveraging a patchwork of open-source tools and custom code to provide a bespoke, low-cost alternative to professional automation solutions.
The Problem With Frameworks
Over the past three decades, I’ve seen my fair share of custom automation frameworks, and none have lasted long or achieved their stated goal.
Look, I’m sure there are exceptions, but in my experience, bespoke automation frameworks take too much effort to build and quickly descend into an unwieldy, fragmented, and unmaintainable mess.
They introduce more challenges than they solve, often only apparent after substantial investment.
Without exception, every framework I have encountered has required exponentially more maintenance than anticipated, and most of them ended up becoming full-time software projects in their own right.
In fact, now I think about it, maybe frameworks are part of why automation used to have such a bad reputation.
Why Do People Still Use Bespoke Automation Frameworks?
Automation frameworks have repeatedly failed to deliver business benefits, yet people still waste time and effort developing them. Why? Well, there are three main reasons: naivety, penny-pinching, and dare I say it, hubris.
It’s incredible how many development teams believe their testing challenges are so specific that only a bespoke solution will suffice.
These teams assume that building in-house will give them better test automation than a professional software tool built by dedicated development teams, and that their patchwork solution will allow them to add features and fix issues according to their own priorities and timelines.
Would you develop a bespoke Office suite to replace MS or Google? No, that would be insane. Affordable, robust, and professionally supported office solutions exist; the same is true for test automation tools.
Plus, what happens when the build team moves on and the core test team are left to maintain things. Do they have the skills?
The absence of upfront licensing fees makes open-source-based custom frameworks appear cost-effective, especially for budget-conscious organisations, but this is a false economy.
Building a Robust Framework Requires Extensive—and Almost Universally Underestimated—Time and Expertise.
What begins as a simple solution inevitably grows more complex as new features are needed, consuming valuable development resources that could be focused on product innovation. As the framework evolves, technical debt will accumulate.
Then, there are the scope limitations; thesein-house frameworks typically support a narrower range of technologies than commercial solutions. As your application landscape diversifies, your framework may be unable to handle new technologies without significant rework.
And you know what? Even if you manage to pull off the almost impossible and develop a reasonable bespoke framework, you’ll be heavily dependent on a few key—and probably expensive—individuals who understand its inner workings. Knowledge gaps will become obvious when these team members leave, and your solution will rapidly deteriorate.
The Good News: You Can Get All The Benefits With A Professional Test Automation Tool
Instead of messing around with a flaky automation framework, you can get all the cost, coverage and flexibility benefits with a professional test automation tool. OpenText Functional Testing (formerly UFT One) is a leading test automation tool for a reason. It provides a viable solution, addressing all the limitations associated with frameworks while providing additional benefits:
Comprehensive Technology Coverage: Unlike most custom frameworks, OpenText supports over 200 technologies out of the box—from web and mobile to legacy systems, SAP, Salesforce, and more. This breadth eliminates the need to develop and maintain multiple frameworks for different parts of your application landscape.
Reduced Maintenance Burden: It’s a professional tool, so OpenText Functional Testing handles all the tool maintenance, be it bug fixes, patches, or compatibility updates. This frees your team to focus on creating valuable test cases rather than maintaining infrastructure.
AI-Powered Resilience: OpenText Functional Testing’s AI-driven object recognition capabilities significantly reduce test maintenance efforts by automatically adapting to UI changes. Implementing this sophisticated feature in a custom framework would require an unrealistic development effort.
Continuous Innovation: OpenText invests heavily in R&D to keep pace with emerging technologies and testing best practices. OpenText Functional Testing benefits from these advancements without additional development effort from your team.
Professional Support: Access to expert support, comprehensive documentation, and a community of users provides resources that in-house frameworks typically lack.
Real-World Comparison
Let’s examine how OpenText Functional Testing compares to custom frameworks across key dimensions:
| Custom Frameworks | OpenText Functional Testing | |
| Initial Setup Time | Months to years of development | Hours of configuration |
| Technology Coverage | Limited to what the team can build | 200+ technologies supported |
| Scalability | Often limited by initial design | Enterprise-grade, built for scale |
| Knowledge Dependency | High risk of knowledge silos | Standardised, documented, widely used |
| Total Cost (3-year) | High (development + maintenance) | Predictable licensing model |
| Innovation Pace | Dependent on internal resources | Continuous updates and improvements |
Bespoke Automation Frameworks Don’t Work. You Need to Make A Strategic Choice
Custom frameworks may seem appealing initially, but even if you manage to get them going, they can rapidly become a complete dog’s dinner.
Successful testing strategies aren’t built on reinventing the wheel but leveraging proven commercial solutions and focusing team expertise on creating tests that deliver business value.
You need to be realistic—there are existing, professional tools that cost less money and do it better.
The long-term advantages of a mature, commercial solution like OpenText Functional Testing are proven.
OpenText Functional Testing is the sensible option for organisations serious about achieving automation while getting the maximum value from their team.
