+description: How to run tests using remote executor.
+---
+
+Some codex integration tests support a running against a remote executor.
+This means that when CODEX_TEST_REMOTE_ENV environment variable is set they will attempt to start an executor process in a docker container CODEX_TEST_REMOTE_ENV points to and use it in tests.
+
+Docker container is built and initialized via ./scripts/test-remote-env.sh
+
+Currently running remote tests is only supported on Linux, so you need to use a devbox to run them
+
+You can list devboxes via `applied_devbox ls`, pick the one with `codex` in the name.
+Connect to devbox via `ssh <devbox_name>`.
+Reuse the same checkout of codex in `~/code/codex`. Reset files if needed. Multiple checkouts take longer to build and take up more space.
