Writing end-to-end tests takes longer than the feature, the scripts break on every UI change, and when they pass they only prove what you told them to check.
TesterArmy replaces the scripts with an agent that uses your product the way a user would, on every pull request. You describe each flow in plain English, for example “log in as the test user, open the API keys page, create a key, check it shows up”. The agent opens a real browser or mobile device, works out what to click from what it sees, and remembers what it learned about your app for the next run. Login, OAuth, one-time passcodes and test accounts are handled.
Every run ends with one of three verdicts: passed, failed or blocked. Blocked means the agent could not get through for a reason outside your product, such as a third-party outage, so it never lands on your team as a bug. Each run keeps a recording, screenshots, browser console and network logs, and a step-by-step transcript of what the agent did and why.
When something fails, paste the report into your coding agent to fix it, or send it to Linear as an issue. Results also go to GitHub, Slack, Discord or a webhook.
It tests web, iOS and Android, including Expo and EAS builds. Runs start from a GitHub pull request, on a schedule against production, or from the terminal through the CLI and the MCP server, so Claude Code, Codex or Cursor can write and run tests for you.
