How TREX tests every PR
Writes tests for each pull request
Greptile automatically generates targeted tests for every PR, covering the changes and edge cases humans might miss.
Runs them in a sandbox
Tests are executed autonomously in an isolated sandbox environment — no setup or workflow changes required.
Shows why the test failed
TREX does not just report pass/fail. It captures the run, attaches the relevant artifacts, and turns the failure into a PR comment your team can verify.
Catch the bugs reading can't
Artifacts
When TREX runs code, it saves the evidence: logs, screenshots, traces, scripts, or videos. If something fails, it's attached to the PR comment.
Works with your stack
TREX runs against the services, dependencies, and framework your repo already uses, not a generic mock environment.
No setup required
Start running tests without custom rules, language-specific setup, or extra scaffolding.
