# agent-qa vs TesterArmy e2e

> Compare agent-qa vs TesterArmy e2e, the open-source framework: TypeScript vs YAML tests, behavioral memory, cached actions, coding agents, and mobile coverage.

A TesterArmy e2e alternative for YAML tests and memory.

The tester-army/e2e framework combines TypeScript assertions with agent-driven actions. agent-qa centers the suite on plain-English YAML and reviewable product observations that carry into later runs.

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.

## Capability comparison

- **Natural-language expectations.** agent-qa: Yes; TesterArmy 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 model options](https://e2e.tester.army/docs), [agent-qa: YAML test authoring](https://vostride.com/docs/agent-qa/guides/first-test.md).

- **Repository tests and local CI.** agent-qa: Yes; TesterArmy e2e: Yes. Both keep tests in the repository and provide a CLI for local and CI execution. e2e's CI guide documents running the framework in your pipeline; the hosted TesterArmy platform's execution model does not apply to this separate project. Sources: [e2e: continuous integration](https://e2e.tester.army/docs/ci), [tester-army/e2e: framework, engines, and license](https://github.com/tester-army/e2e), [agent-qa: coding-agent verification loop](https://vostride.com/docs/agent-qa/guides/coding-agent-workflow.md).

- **Coding-agent workflow.** agent-qa: Yes; TesterArmy e2e: Yes. e2e supplies a skill, MCP app inspection, CLI execution, and reports for coding agents. agent-qa supplies Skills and MCP around test authoring, execution, and run inspection. Both can close a development loop with evidence. Sources: [e2e: coding agents and reports](https://e2e.tester.army/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; TesterArmy 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: test authoring and model options](https://e2e.tester.army/docs), [agent-qa: model configuration](https://vostride.com/docs/agent-qa/configuration/global-config.md).

- **Reuse on repeated runs.** agent-qa: Yes; TesterArmy e2e: Yes. e2e replays verified agent actions and hands back to the agent when replay no longer matches; AI assertions stay live. agent-qa reuses action plans while observing the current app. Caching exists in both, with different execution semantics. Sources: [e2e: verified action replay](https://e2e.tester.army/docs/cache), [agent-qa: action-plan caching](https://vostride.com/docs/agent-qa/caching.md).

- **Curated behavioral memory.** agent-qa: Yes; TesterArmy e2e: Partial. e2e documents a replay cache of recorded actions. agent-qa additionally curates product, suite, and test observations as Markdown for retrieval during later steps. The cited e2e docs do not establish that same behavioral-memory lifecycle. Sources: [e2e: verified action replay](https://e2e.tester.army/docs/cache), [agent-qa: behavioral memory](https://vostride.com/docs/agent-qa/memory.md).

- **Web and native mobile targets.** agent-qa: Yes; TesterArmy e2e: Yes. e2e uses Playwright for browsers and agent-device for iOS simulators and Android emulators. agent-qa supports web and native Android/iOS, with configured Appium devices. Validate your required device and browser matrix rather than assuming identical coverage. Sources: [tester-army/e2e: framework, engines, and license](https://github.com/tester-army/e2e), [agent-qa: native mobile setup](https://vostride.com/docs/agent-qa/guides/mobile-testing.md).

- **Published source.** agent-qa: Yes; TesterArmy e2e: Yes. e2e is Apache-2.0 open source. agent-qa is source available under FSL-1.1-ALv2, with an Apache 2.0 future license. These grant different rights today; source availability should not be mistaken for identical licensing. Sources: [tester-army/e2e: framework, engines, and license](https://github.com/tester-army/e2e), [agent-qa: license terms](https://vostride.com/license.md).

## Where agent-qa changes the testing workflow

### Review journeys as plain-English YAML

Keep the desired outcome in a small test file. agent-qa suits teams that want reviewers to focus on product behavior, with setup and cleanup handled by explicit hooks.

### Retain knowledge beyond action reuse

Use behavioral memory to preserve product observations across runs. Inspect what was learned and remove stale facts independently of the action cache.

### 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 tester-army/e2e framework. Its repository describes APIs as still evolving before 1.0. Partial indicates that the cited docs do not establish the same memory model, not that extensions are impossible. No comparative performance benchmark was run.

## Evaluate agent-qa against TesterArmy 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.

## Frequently asked questions

### Is tester-army/e2e the hosted TesterArmy service?

No. This comparison covers the separately published e2e framework and its local test runner. TesterArmy's hosted platform has its own comparison. Sharing a maintainer does not make their execution models or licenses interchangeable.

### 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.
