Design and export reproducible AI evaluation tests

Build template-driven test suites for instruction-following, summarization, code generation, multi-turn dialogue and safety probes. Export machine-evaluable packages (JSON, JSONL, CSV) and human-review checklists for CI or offline review — without sending your private test data to third parties.

Reduce manual setup

Why use a dedicated AI test generator?

Ad-hoc prompts and one-off checks make it hard to reproduce regressions, cover edge cases, or integrate tests into CI. This generator provides structured templates, pass/fail scaffolds, and export formats so teams can run the same tests locally, in CI, or against hosted endpoints.

  • Consistent test inputs and expected outputs tracked with versioned metadata
  • Machine-evaluable assertions plus human-review checklists
  • Bundles export-ready files that fit evaluation runners and CI systems

Ready-made prompt clusters

Template-driven suites for common AI tasks

Start from curated templates then customize variants. Each template includes example inputs, expected outputs or assertion rules, and suggested pass/fail criteria focused on reproducibility and coverage.

  • Instruction-following: enforce exact output formats and schema
  • Summarization fidelity: preserve claims and numeric facts
  • Extraction / NER: require structured JSON arrays or empty arrays when no matches
  • Code generation: include unit-test style expectations and sandbox rules
  • Multi-turn dialogue: simulate corrections and stateful exchanges
  • Safety probes and adversarial paraphrases to reveal brittle behaviors

Instruction-following template

Define the assistant role, required output schema, and a fail rule if output departs from format.

  • Generate N variants targeting edge instruction types
  • Include example good/bad outputs for human review

Code generation template

Small focused tasks with expected function outputs and disallowed behaviors (no external network calls).

  • Attach unit-style assertions to mark pass/fail
  • Export expected inputs and outputs for automated runners

Use tests where you already run checks

Export formats and CI integration

Export entire test packages in JSON, JSONL or CSV. Each export includes inputs, expected outputs, metadata (version, template, author), and optional machine-evaluable assertions so evaluation runners and CI jobs can execute or hand off tasks to human reviewers.

  • JSON/JSONL for eval frameworks and model harnesses
  • CSV for spreadsheet-based review or manual QA
  • Include human-review checklists alongside machine assertions

Integrate into CI

Drop exported JSON/JSONL into your repo and invoke your test runner from GitHub Actions or GitLab CI to check model changes as part of PRs.

  • Store test artifacts in the repository or a secure artifact store
  • Run automated assertions during PR checks and surface failing cases to reviewers

Cover diverse failure modes

Focused prompt clusters included

The generator provides clusters that target specific classes of failures so you don’t rely on ad-hoc sampling. Use these clusters to increase coverage for edge cases and to stress-test instruction adherence, safety, numeric reasoning, and localization.

  • Adversarial paraphrase cluster: slang, typos, code-mixing
  • Edge-case numeric reasoning cluster
  • Extraction/NER with ambiguous and nested mentions
  • Localization and format enforcement

Keep your data safe

Privacy-conscious and reproducible

Generate and export test suites without sending private test data to third parties. The tool supports offline exports and local-only workflows so you can run tests against on-prem or locally hosted models while retaining full control over inputs and expected outputs.

  • Export artifacts locally before running any remote evaluations
  • Include reproducible metadata: template version, test author, creation timestamp
  • Use private model endpoints or local LLMs for evaluation

Who benefits

Target audiences and use cases

Built for practitioners who need repeatable, auditable test suites for model quality checks and hiring or instructional assessments.

  • ML engineers and model evaluators creating regression suites
  • QA engineers and prompt engineers validating behavior changes
  • Product managers embedding tests into release gates
  • Instructors and interviewers building reproducible technical assessments

FAQ

How do I export generated tests for CI (JSON, CSV, JSONL)?

Choose Export → Format and select JSON, JSONL, or CSV. Exports include input prompts, expected outputs or assertion rules, and metadata (template name, version, author). For CI, commit the exported file(s) to your repository and configure your test runner to load the test suite and call your model endpoint. The typical flow is: 1) add tests to the repo, 2) run an evaluation script in the CI job that loads the JSON/JSONL and asserts pass/fail, 3) surface failures as PR checks.

Which model types and hosting setups can run tests generated here?

Exported test packages are provider-agnostic and can be executed against OpenAI-compatible endpoints, Anthropic-style assistants, hosted provider APIs, or local/on-prem inference for Llama-style models. The exported format focuses on inputs and expected outputs so your evaluation harness can translate those into provider-specific calls.

Can I keep my test inputs private and generate tests locally or offline?

Yes. The generator supports privacy-conscious workflows: generate test suites in the browser and download exports locally, or use an offline build to produce packages without sending test content to external services. You decide whether to run evaluations locally, on-prem, or against hosted endpoints.

How should I define pass/fail criteria for subjective tasks like summarization?

Combine machine-evaluable assertions with human-review scaffolds. For summarization, use a mix of objective checks (contains main claim, preserves specific numeric facts) and a short rubric for human reviewers (scale for faithfulness, coverage, and hallucination). Export both assertions and the rubric so CI can run quick checks and route ambiguous cases to reviewers.

What templates are available for code generation and multi-turn dialogue tests?

Code templates include small-scale tasks with explicit function signatures, input-output examples, and unit-style assertions to mark pass/fail. Multi-turn dialogue templates include scripted user corrections and expected assistant acknowledgements to verify statefulness across turns. Each template contains example variants you can expand to increase coverage.

How do I convert a manual QA checklist into machine-evaluable assertions?

Map each checklist item to an assertion that can be evaluated automatically where possible. Example: a checklist item 'Return dates in ISO format' becomes an assertion that the assistant's output matches an ISO date regex. For subjective checks, include an explicit rubric and example good/bad outputs so human reviewers can apply consistent judgments.

Can generated tests be used for hiring or technical interviews? Any recommended best practices?

Yes—exported tests provide reproducibility and comparable evaluation conditions. Best practices: avoid leaking proprietary data, include clear instructions and time limits, pair automated checks with human review for creative tasks, and document rubric and grading criteria alongside the test package to ensure fairness and reproducibility.

How do I integrate exported tests into GitHub Actions or other CI runners?

Add the exported JSON/JSONL files to your repository or fetch them as artifacts. In your workflow: install the evaluation harness, load the test suite, call the target model endpoint or local runner, evaluate assertions, and fail the job on unacceptable regressions. Keep model credentials in secure secrets and split long-running or expensive tests into separate CI stages to control cost.
