Frequently asked questions
What is Software testing?
Tools that generate or maintain tests as a testing product, not as an IDE assistant. Jobs: unit test generation; fixture generation; test maintenance suggestions.
What should not be listed as Software testing?
Products whose buyer job is QA automation runners, coding assistants, or production SRE copilots. Those belong on their own category page so search queries are not split.
Has AI Trustmark independently assessed every Software testing supplier?
No. A category listing is descriptive. Independent assessment is shown only on company or product pages that carry Trustmark evidence.
Should coding assistants be allowed to send private source code to third-party models?
That is a buyer policy decision. Procurement should require the default data-use terms, retention, whether snippets leave the organisation, and whether secrets are redacted. A listing under coding assistants does not mean code stays on-premises.
How should prompt injection and tool-output attacks be controlled?
Agents that read untrusted content or tool output can be instructed to exfiltrate data or take writes. Buyers should ask what is treated as untrusted, whether tool output can change the plan, and what tests were run. Scanner marketing is not the same as independent testing.
How can buyers tell whether customer data is used to train models?
Ask whether prompts, files, logs or outputs are used to train, fine-tune or evaluate models, including by subprocessors. Require the contractual default, any opt-out, and whether the setting can be changed silently. Treat marketing 'we do not train' claims as unverified until evidenced.
What model or provider changes should a buyer insist on being told about?
Material change usually includes a new model family, new region, new subprocessor, new write-capable tool, or a change that affects logging, privacy or human oversight. Those changes should trigger evidence refresh rather than a silent release.
How should buyers verify where AI customer data is processed?
Ask for the named processing locations, cloud regions and any subprocessors that see prompts, files or outputs. A directory listing is not evidence of residency. Independent assessment records the locations that were in scope on the assessment date.
