feat: add KinD integration tests (#141)
* feat: add KinD integration testsAdd integration tests that run against a real Kubernetes cluster usingKinD (Kubernetes in Docker). This addresses#58.Changes:- Add integration_test.go with tests for: - Pod events (create/delete) - ReplicaSet events - Multi-namespace support - Label selector filtering- Add .github/workflows/integration.yaml CI workflow that: - Runs lint and unit tests first - Then runs integration tests with KinD - 10 minute timeout- Add scripts/kind-setup.sh for local development- Update README.md with integration test documentationThe integration tests use the existing fakeAgentAPI to mock the Coderserver, focusing on validating real Kubernetes informer behavior.* fix: use real clock for integration testsThe integration tests were using quartz.NewMock(t) which creates a mockclock that doesn't advance automatically. This caused timeouts whenwaiting for log source registration because the timers in the logqueuer never fired.Changes:- Remove mock clock usage from all integration tests- Use real clock (nil) which is the default- Reduce logDebounce to 5s for faster test execution- Increase informer sync wait to 1s for reliability* fix: remove duplicate unit-test job from integration workflow* fix: make integration tests more robust against event orderingThe tests now use waitForLogContaining which continuously collectslogs until finding the expected message, rather than expectingspecific messages in the first batch of logs received.This fixes flaky tests caused by Kubernetes scheduling eventsarriving before pod lifecycle events.* fix: address PR review feedback- Add safety check to prevent running integration tests against non-KinD clusters (detects localhost/127.0.0.1/kind in host)- Use SHA pinning for GitHub Actions with version comments- Add INTEGRATION_TEST_UNSAFE=1 escape hatch for special cases* chore: add binary to gitignore* feat: add Makefile with lint/shellcheck and fmt/shfmt targets- Add Makefile with build, test, lint, and fmt targets- Fix shellcheck warnings in scripts/helm.sh and scripts/version.sh- Format shell scripts with shfmt* chore: update GitHub Actions dependencies and clean up .gitignore- Update actions/checkout to v6.0.1- Update actions/setup-go to v6.1.0- Update helm/kind-action to v1.13.0- Remove buildcoder-logstream-kube from .gitignore* fix: address remaining PR review comments- Fix safety check logic: check INTEGRATION_TEST_UNSAFE env var before calling t.Fatalf, not after- Fix .gitignore: add coder-logstream-kube and build/ on separate lines* fix: use Go 1.24 in integration workflow to match go.mod

## Development
69+
70+
### Running Tests
71+
72+
Unit tests can be run with:
73+
74+
```console
75+
go test ./... -race
76+
```
77+
78+
### Integration Tests
79+
80+
Integration tests run against a real Kubernetes cluster using [KinD (Kubernetes in Docker)](https://kind.sigs.k8s.io/).
81+
82+
**Prerequisites:**
83+
-[Docker](https://docs.docker.com/get-docker/)
84+
-[KinD](https://kind.sigs.k8s.io/docs/user/quick-start/#installation)
85+
-[kubectl](https://kubernetes.io/docs/tasks/tools/)
86+
87+
**Setup and run:**
88+
89+
```console
90+
# Create a KinD cluster
91+
./scripts/kind-setup.sh create
92+
93+
# Run integration tests
94+
go test -tags=integration -v ./...
95+
96+
# Clean up when done
97+
./scripts/kind-setup.sh delete
98+
```
99+
100+
The integration tests validate:
101+
-Pod event streaming with real Kubernetes informers
102+
-ReplicaSet event handling
103+
-Multi-namespace support
104+
-Label selector filtering
105+
