Migrate bats tests to golang - #366
Conversation
WalkthroughThe pull request replaces the Ruby/RSpec BATS execution path with a Go Ginkgo suite. It adds configuration, BOSH command, manifest, and acceptance-test helpers. The suite covers VM lifecycle, networking, persistent disks, recreation, and SSH. Concourse tasks now run Merge Risk: 🟠 High · up to The replacement BATS task cannot run because its image lacks Go 1.25. The suite also has cleanup, timeout, configuration, and coverage gaps that can leave infrastructure behind or miss CPI regressions, so it should not merge as-is. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@ci/bats/go.mod`:
- Around line 1-3: Update the BATS Docker image defined by the
openstack-cpi-release Dockerfile to install and expose the Go 1.25 toolchain
required by the ci/bats module and run-bats.sh’s go test ./... invocation.
Ensure the image contains a usable Go runtime without relying on runtime
toolchain downloads.
In `@ci/bats/helpers/bosh.go`:
- Line 32: Update Runner.Run and its callers to accept operation-specific
context deadlines, including SSH paths, and use the context when launching
bosh-go so cancellation reaches the entire process tree. Ensure CombinedOutput
returns when the deadline expires and preserve existing cleanup behavior by
avoiding unbounded command execution.
In `@ci/bats/helpers/config.go`:
- Line 136: Update loadSpec to validate that the unmarshaled properties.networks
list is present and non-empty, returning a configuration error when it is
missing or empty before PrimaryNetwork can access c.BATs.Networks[0]. Preserve
the existing configuration flow for valid network lists.
In `@ci/bats/networking_test.go`:
- Around line 63-69: Extend the instance verification loop to assert network
assignment: match each instance by its `Name`, require `primary-vm` to have
`primary.StaticIP` and `secondary-vm` to have `secondary.StaticIP`, while
preserving the existing running-state and instance-count assertions.
- Line 16: Update the AfterEach cleanup around bosh.DeleteDeployment in the
networking tests to use a per-spec success flag set only after bosh.Deploy
succeeds, asserting deletion only in that case. When deployment succeeds,
require DeleteDeployment to succeed in both affected files instead of ignoring
its result, while preserving cleanup behavior for failed deployments.
In `@ci/bats/persistent_disk_test.go`:
- Around line 40-47: Enhance the persistent-disk recreation test around
bosh.Recreate and the subsequent bosh.Instances check to verify disk
preservation, not only that the VM remains running. Record the attached disk
identity or write a marker to the persistent disk before recreation, then
confirm the same identity or marker afterward.
In `@ci/pipeline.yml`:
- Line 185: Update the bats-print-errors task around the bosh-go task-listing
command to provide the director URL by exporting BOSH_ENVIRONMENT or passing it
with --environment, while preserving the existing credentials and CA certificate
setup.

Add Go 1.25 to the BATS image. The task uses an image built from ci/docker/openstack-cpi-release/Dockerfile, which installs no Go toolchain and has no runtime toolchain download. run-bats.sh invokes go test ./..., so the task can fail before executing the BATS suite.

Bound BOSH commands and cancel their process trees.
Runner.Run blocks in CombinedOutput without a context. The BOSH CLI has no universal timeout for these paths, including SSH. A stalled command can occupy the BATS process until go test -timeout 90m kills it; Ginkgo AfterEach cleanup cannot run after that process termination. Pass operation-specific deadlines to Runner.Run and cancel bosh-go together with any child processes.

Reject an empty properties.networks list during configuration loading.
loadSpec assigns the unmarshaled list without validation. If the list is missing or empty, PrimaryNetwork reaches c.BATs.Networks[0] and panics when the suite initializes. Return a configuration error from loadSpec.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Assert cleanup only after a successful deployment. AfterEach runs even when bosh.Deploy fails, so guard the deletion assertion with a per-spec success flag. When deployment succeeds, require bosh.DeleteDeployment(deployment) to succeed in both files. The fixed deployment names are reused by later specs and retries, so ignored deletion errors can leave state that affects them.

Verify the network assignment of each instance.
These assertions only prove that two instances are running. Both instances can use the same network or incorrect IPs and still pass.
Assert that primary-vm has primary.StaticIP and secondary-vm has secondary.StaticIP.

Verify persistent-disk preservation across recreation.
The test only verifies VM process state. A CPI that replaces, detaches, or loses the persistent disk still passes this test.
Record and compare the attached disk identity, or write data to the persistent disk before recreation and verify the same data afterward.

Set BOSH_ENVIRONMENT before listing tasks.
The bats-print-errors task runs in a separate container. Its image only installs bosh-go, and the task exports credentials and the CA certificate but no director target. Therefore, bosh-go -n tasks --all --recent=50 exits before it can print diagnostics. Provide the director URL to this task and export it as BOSH_ENVIRONMENT, or pass it with --environment.

Reimplement BATS in Go
The previous BATS suite was a Ruby/RSpec suite from the
bosh-acceptance-testsrepo. Ruby hasbeen stripped from the CI image (see #361, #362, #363), so the Ruby runner no longer works.
This PR replaces it with a self-contained Go/Ginkgo suite that lives inside the repo itself.
What changed
New:
ci/bats/Go moduleA new
ci/bats/package contains the full acceptance suite. It uses the same Ginkgo/Gomegaframework already used by
src/openstack_cpi_golang/, and drives BOSH exclusively viaexec.Command("bosh-go", ...)— no director SDK, consistent with the existing bash task scripts.Scenarios covered (mirrors the active subset from the old RSpec run; skipped tags dropped):
bosh recreatebosh recreatebosh sshtunnels through the jumpbox successfullySuite setup reads the same
BAT_*/BOSH_*env vars as before. SettingBAT_DIRECTOR=dry-runskips the real-director setup, allowing local compile/syntax checkswithout a live environment.
New CI task:
ci/tasks/run-bats.{sh,yml}Replaces
run-manual-networking-bats.{sh,yml}. The shell script sourcesutils.sh, exportsthe same Terraform/BOSH variables as before, writes
bats-config.ymlfrom the same template,and then runs
go test ./... -vinci/bats/.Pipeline changes (
ci/pipeline.yml)run-batstask now points atrun-bats.yml(wasrun-manual-networking-bats.yml).bats_rspec_tagsparam (no longer applicable).batsgit resource (thecloudfoundry/bosh-acceptance-testsclone is nolonger needed).
bats-print-errorsensure step (which required Ruby viaprint_task_errors.rb) isreplaced with an inline bash snippet that runs
bosh-go -n tasks --all --recent=50.Deleted
ci/tasks/print_task_errors.{sh,yml}— Ruby-dependent error reporter, no longer needed.ci/tasks/run-manual-networking-bats.{sh,yml}— renamed/replaced byrun-bats.*.
