Why One-Size-Fits-All AI Testing Does Not Work
As more organisations rush to adopt artificial intelligence for software testing, there is a growing assumption that AI is the best answer for every environment. In reality, many teams quickly discover that AI-based test automation does not suit every platform, industry or security model.
If your software depends on desktop applications, legacy systems, virtual desktops, air-gapped networks or stringent compliance requirements, AI testing often falls short. This is where T-Plan stands apart. With over 25 years of delivering secure, repeatable, cross-platform testing, T-Plan continues to be the trusted choice for industries that cannot afford to take risks.
Why AI Testing Is Not Always Suitable
-
- Repeatability and Script Stability
AI-generated scripts do not guarantee the same output every time. By design, AI models draw on different data and contexts with each execution. This means the same prompt today might not produce an identical script tomorrow. For sectors such as finance, healthcare or defence, this lack of consistency makes audits and validation nearly impossible.In contrast, T-Plan’s deterministic approach ensures that test scripts are repeatable, fully version controlled and produce the same result every time. This is critical for meeting compliance and quality standards.
- Repeatability and Script Stability
-
- Limited Platform Coverage
Most AI and open-source automation tools focus on web testing. If your applications are built on Windows, macOS, Linux, mobile devices, or involve legacy systems or Citrix, these tools often cannot help. Many also require constant cloud connectivity, which is not permitted in secure, closed networks.T-Plan is specifically built to support diverse environments, including desktop, mobile, legacy and virtual systems. It does not depend on cloud infrastructure, so your tests can run entirely within your secure network.
- Limited Platform Coverage
-
- Security and Compliance Risks
Cloud-based AI platforms frequently send data outside your organisation. In regulated industries, this is unacceptable. Strict data governance, GDPR, ISO or internal policies demand that sensitive data stays on site.With T-Plan, all test execution and data remain on your premises. This approach protects your intellectual property and guarantees compliance with your security framework.

Proven Success Stories That Back This Up
A leading defence organisation chose T-Plan to test a critical COVID-19 app that needed to run flawlessly across iOS, Android, macOS, Linux and Windows. The team was testing within 15 minutes of installation and had repeatable tests running across five platforms in under four hours, all within a secure, offline environment.
“To be able to start repeating tests within 3 to 4 hours is quite amazing.”
