AI that understands your product before it writes your tests.
Everything behind this text is your project: requirements, documentation, defects, and the suite you already wrote. The Tesbo Context Engine reads all of it before it drafts a single case.
Your team already tried ChatGPT. That is exactly why they stopped.
2. Enter a refund amount.
3. Submit and confirm the refund is processed.
Expected: the refund completes successfully.
A model can only be as specific as what it has read. Prompting harder does not add knowledge it never had.
Before it writes a single test, it reads everything you already know.
Six sources, indexed and kept current. Generation is the last step.
Every case arrives with its reasons attached.
No black box, and nothing to take on faith. Each generated case cites the requirement it came from, the document that set the rule, and the defect that made it worth testing. Review becomes a thirty-second read instead of a rewrite.
Partial refund on a split-tender order settles to the original card before the wallet
Priority set to P1 — this area has produced 3 production defects in 6 months
This is what your project looks like, grounded.
Free to self-host, free to start in the cloud. No credit card required.
04 · Try it hereSwitch the context off and watch the case fall apart.
This is the case from the section above. Every source on the left is a real input the engine reads. Turn one off and the part of the case it was holding up disappears with it.

The longer your team uses it, the less they edit.
Every approval, edit and rejection goes back into the index. Corrections become conventions. The engine learns where your bar sits, and the drafts move toward it. This is the part a chat window can never do: it forgets you the moment you close the tab.
Requirements, docs, cases and defects are read and vector-indexed as they change.
Cases are generated against retrieved context, with every source cited.
Your engineer approves, edits or rejects. Nothing lands without a decision.
The decision becomes context. The next batch starts from a higher bar.
Nine features. One job: keep the context true.
Tesbo is a complete test management platform. Every part of it exists to get knowledge into the engine, keep it current, or prove what came out.
Knowledge Base + RAG
Hierarchical docs and files, versioned and vector-indexed. This is where your product truth lives, and the first thing the engine reads.
Requirement import
Pull stories and acceptance criteria from Jira and Linear. Context arrives with the ticket instead of being re-typed into a prompt.
Test case repository
Nested suites, priorities and rich steps. Your existing cases are not just records, they are the style guide the engine writes against.
Bug & defect tracking
Bugs filed from failed runs, linked to the case that caught them. Every failure becomes an input to the next generation.
Human review queue
Approve, edit or reject in one place. Each decision teaches the engine your bar and nothing reaches the repository unreviewed.
Requirements traceability
Because cases are generated from requirements, the matrix fills itself. Coverage rolls up across every run without anyone maintaining links.
Runs, plans & reports
Pass rates, flaky-test detection and risk hotspots. Results tell the engine which context mattered and which areas keep breaking.
Tesbo MCP server
Point Claude, Cursor or your own agent at Tesbo and they inherit the same project context, under the same human-approval rules.
Audit logs
Every action by agent or human, logged in full. When an auditor asks why a case exists, the answer is one click away.
What you are buying is not generation. It is a project that knows itself.
Test volume is the easy part. What a QA lead actually needs is coverage they can defend, output the team does not silently discard, and a release call backed by evidence.
Coverage you can put in front of a stakeholder
Requirement-to-case traceability is a by-product of how cases are generated, not a spreadsheet somebody maintains on Fridays.
Drafts your engineers approve instead of rewrite
Adoption fails when the output is generic. Grounded cases arrive in your format, at your depth, and survive review.
Knowledge that stays when people leave
The context lives in the project, not in a senior engineer's memory or in someone's private chat history.
Your context is the most sensitive asset you own. Keep it on your own servers.
Everything the engine reads — requirements, documentation, defect history — is your intellectual property. Tesbo is Apache 2.0 licensed and self-hostable anywhere Docker runs, with your own Postgres and your own vector index. Nothing phones home. It is a true open source test case management software you fully control.
Questions, answered.
Yes. As open source Test Management Software, self-hosted Tesbo is free forever under Apache 2.0, with no per-seat fees. Cloud hosting is also available if you would rather not run your own servers.
Stop prompting a model that has never seen your product.
Connect a project, point the Context Engine at your requirements and docs, and read the first batch of cases it drafts. No procurement, no seat math.
