The 5-second version
- TesterArmy supports testing any mobile framework including native and Expo apps by running built binaries in the cloud.
- PR-based testing is available: the tool analyzes PR changes to generate test plans and deploys agents to verify them automatically.
- Pricing tiers currently target lower usage; higher-volume users need to contact sales or use the startup plan.
- The service handles infrastructure challenges like CAPTCHAs, authentication, email OTP (each agent gets its own inbox), and video recording.
- Founders argue traditional E2E tests are brittle due to selector dependencies, wait times, and dynamic content limitations that pure LLM-based testing struggles with.

Fable (rip) is absurdly good at this, great time to build a product around it, you definitely need the harness, but it feels like it just turned the corner to be able to do really in depth and edge case work. Do you handle heterogenous environments and network connectivity simulation as well? I am working on a mobile app and occasionally having users just lose a request or two can put the state machine into unusual modes.Read on HN ↗
Is there a long term future in hand-crafted UI/UX? Maybe not. Is there a future where we still have traditional UX? Absolutely. I don't want to write a whole dissertation on this topic, so I'm just going to mention that we tried to build AI voice assistants for a decade, and while LLMs have basically solved understanding, they have not solved the UX portion.Read on HN ↗

E2E tests are now quick to write due to LLMs, and are then deterministic AND cheap to run. How would this compare to the token costs of running an agent the whole time for each test? How do you make sure results stay stable regardless of the nondeterministic nature? Do customers still need to create test cases - any way to import from test case management system - based on which they could have already generate e2e tests locally?Read on HN ↗
Great presentation On a slight tangent, since we are all here... Does anyone still believe there is a long-term future in traditional UI/UX? It feels like a lot of attention is still going into landing pages, dashboards, and CRUD apps, while overlooking a bigger shift where fewer people will actually need to interact with those interfaces directly when the same tools can perform the underlying tasks automatically, without much UI at all. So the bigger question is does UI/UX evolve into somet…Read on HN ↗
