Remove TestGrantViaExitNodeSteering and TestGrantViaMixedSteering. Exit node traffic forwarding through via grants cannot be validated with curl/traceroute in Docker containers because Tailscale exit nodes strip locally-connected subnets from their forwarding filter. The correctness of via exit steering is validated by: - Golden MapResponse comparison (TestViaGrantMapCompat with GRANT-V31 and GRANT-V36) comparing full netmap output against Tailscale SaaS - Filter rule compatibility (TestGrantsCompat with GRANT-V14 through GRANT-V36) comparing per-node PacketFilter rules against Tailscale SaaS - TestGrantViaSubnetSteering (kept) validates via subnet steering with actual curl/traceroute through Docker, which works for subnet routes Updates #2180
Integration testing
Headscale relies on integration testing to ensure we remain compatible with Tailscale.
This is typically performed by starting a Headscale server and running a test "scenario" with an array of Tailscale clients and versions.
Headscale's test framework and the current set of scenarios are defined in this directory.
Tests are located in files ending with _test.go and the framework are located in the rest.
Running integration tests locally
The easiest way to run tests locally is to use act, a local GitHub Actions runner:
act pull_request -W .github/workflows/test-integration.yaml
Alternatively, the docker run command in each GitHub workflow file can be used.
Running integration tests on GitHub Actions
Each test currently runs as a separate workflows in GitHub actions, to add new test, run
go generate inside ../cmd/gh-action-integration-generator/ and commit the result.
