An e2e alternative for YAML tests and reviewable memory. TesterArmy is now e2e. Its open-source framework combines TypeScript assertions with agent-driven actions on web, iOS, and Android. agent-qa uses plain-English YAML and memidex records learned from run evidence. Try agent-qa, a source-available QA runtime for teams that prefer declarative journeys and file-backed behavioral memory. Keep expectations, runtime configuration, and evidence in a workspace shared by engineers and coding agents. ## The choice for recurring QA Choose agent-qa for YAML expectations and curated behavioral memory. Choose e2e when mixing deterministic TypeScript locators with AI goals is the authoring model you want. Both offer local tests, model choice, mobile targets, and execution reuse.

Product capabilities and pricing can change; verify details with each vendor before making a purchase decision. ## Capability comparison - **Natural-language expectations.** agent-qa: Yes; e2e: Yes. e2e combines agent goals, AI assertions, and deterministic checks in TypeScript. agent-qa expresses journeys and verification steps in YAML. The choice is the review and authoring contract your team wants to maintain. Sources: [e2e: test authoring and supported platforms](https://e2e.com/docs), [agent-qa: YAML test authoring](https://vostride.com/docs/agent-qa/guides/first-test.md). - **Repository tests and local CI.** agent-qa: Yes; e2e: Yes. Both keep tests in the repository and run locally or in CI on infrastructure you configure. e2e is not limited to the old TesterArmy cloud workflow. With either framework, your chosen model provider and any hosted devices remain separate dependencies.

Both can close a development loop with evidence. Sources: [e2e: coding agents and reports](https://e2e.com/docs/coding-agents), [agent-qa: coding-agent verification loop](https://vostride.com/docs/agent-qa/guides/coding-agent-workflow.md). - **Bring your own model.** agent-qa: Yes; e2e: Yes. e2e supports your own subscription, API key, or local model; deterministic tests need no model. agent-qa provides named model configurations and compatible endpoints. Compare the actual models and inference costs you intend to use. Sources: [e2e: subscriptions, API keys, and local models](https://e2e.com/docs/models), [agent-qa: model configuration](https://vostride.com/docs/agent-qa/configuration/models.md). - **Reuse on repeated runs.** agent-qa: Yes; e2e: Yes. e2e records agent actions after a later check verifies the result, then replays them until the app changes; AI assertions stay live. agent-qa replays eligible actions when the step, configuration, variables, and screen match. Verification steps are not cached in either workflow. Sources: [e2e: verified action replay](https://e2e.com/docs/cache), [agent-qa: action-plan caching](https://vostride.com/docs/agent-qa/caching.md). - **Curated behavioral memory.** agent-qa: Yes; e2e: Partial. e2e documents verified action replay. agent-qa's memidex also retains facts, cautions, and procedures with evidence and trust history in reviewable files. The cited e2e docs do not establish that same lifecycle. In agent-qa v0.2, most committed records are not yet served on a fresh clone without local indexes and artifacts. Sources: [e2e: verified action replay](https://e2e.com/docs/cache), [agent-qa: behavioral memory](https://vostride.com/docs/agent-qa/memory.md). - **Web and native mobile targets.** agent-qa: Yes; e2e: Yes. Both support web, iOS, and Android. e2e documents simulators, emulators, connected phones, and hosted device providers. agent-qa drives native apps through Appium, including configured local devices and BrowserStack. Check the exact device and browser matrix your release requires.

These grant different rights today; source availability should not be mistaken for identical licensing.

Review the files in git and correct learned records through agent-qa's inspection tools; hand edits invalidate their integrity checks. ### Share the run with your coding agent agent-qa connects tests, run artifacts, memory, and local inspection tools in one workspace. Evaluate whether that shared view helps your team diagnose a failure and make a focused rerun. ## Verdict agent-qa is a useful e2e alternative when plain-English YAML and retained product knowledge are central to your suite. e2e remains a strong fit for teams that want deterministic and agentic behavior together in TypeScript. > Note: This page covers the current e2e framework, formerly branded TesterArmy, rather than the retiring hosted platform. Partial means the cited docs do not establish equivalent behavior. No comparative performance benchmark was run. ## Evaluate agent-qa against e2e 1. Translate one TypeScript journey into YAML while preserving its assertions, target, and test data. 2. Run both on the same revision with comparable models and device settings; save the initial reports. 3. Compare warm and cold runs, then break an expected outcome to check that cached execution still exposes the regression. 4. Review the test diff, failure evidence, memory changes, and license requirements before moving more coverage.

TesterArmy announced its rebrand to e2e on November 3, 2026. This page now covers the open-source framework at e2e.com. The announcement says the former hosted platform remains available until January 15, 2027, with migration help, and describes e2e cloud as planned for 2027 rather than a current framework requirement. ### Does e2e already support AI tests and caching? Yes. It combines agent-driven steps with deterministic checks and caches verified actions for replay. agent-qa also reuses execution work; its additional memory layer stores behavioral observations rather than just action plans. ### Can coding agents use both frameworks? Yes. e2e documents a skill, MCP exploration, and CLI reports. agent-qa offers a test-centered CLI, MCP, Skills, and a run inspector. Compare failure diagnosis using the same broken journey instead of choosing on the presence of an MCP server alone. ### Are e2e tests compatible with agent-qa YAML? There is no drop-in compatibility claimed here. Translate the TypeScript test's intent and assertions into agent-qa steps, and carry over setup data through the appropriate configuration and hooks. Keep exact checks meaningful during the conversion. ### When should I keep using e2e? Keep it when direct TypeScript control, deterministic locators alongside AI actions, or Apache-2.0 licensing are decisive requirements. Evaluate agent-qa when YAML review and persistent behavioral memory better fit your recurring QA process. ## Sources - [e2e: current product and execution model](https://e2e.com/) - [e2e: TesterArmy rebrand and hosted-platform transition](https://e2e.com/blog/seed) - [e2e: framework source and Apache-2.0 license](https://github.com/tester-army/e2e) - [e2e: test authoring and supported platforms](https://e2e.com/docs) - [e2e: subscriptions, API keys, and local models](https://e2e.com/docs/models) - [e2e: native mobile targets and device providers](https://e2e.com/docs/mobile) - [e2e: verified action replay](https://e2e.com/docs/cache) - [e2e: coding agents and reports](https://e2e.com/docs/coding-agents) - [e2e: continuous integration](https://e2e.com/docs/ci) - [agent-qa: YAML test authoring](https://vostride.com/docs/agent-qa/guides/first-test.md) - [agent-qa: coding-agent verification loop](https://vostride.com/docs/agent-qa/guides/coding-agent-workflow.md) - [agent-qa: model configuration](https://vostride.com/docs/agent-qa/configuration/models.md) - [agent-qa: action-plan caching](https://vostride.com/docs/agent-qa/caching.md) - [agent-qa: behavioral memory](https://vostride.com/docs/agent-qa/memory.md) - [agent-qa: native mobile setup](https://vostride.com/docs/agent-qa/guides/mobile-testing.md) - [agent-qa: license terms](https://vostride.com/license.md) ## Compare other approaches - [agent-qa vs agent-device](https://vostride.com/product-comparison/agent-qa-vs-agent-device.md): Compare Callstack's agent-device with agent-qa for device control, replay suites, natural-language test contracts, and behavioral memory. - [agent-qa vs Midscene.js](https://vostride.com/product-comparison/agent-qa-vs-midscene.md): Both support natural-language UI tests.
