Integration Test

This integration test validates that huatuo-bamai can start correctly with mocked /proc and /sys filesystems and expose the expected Prometheus metrics.

The test runs the real huatuo-bamai binary and verifies the /metricsendpoint output without relying on the host kernel or hardware.

What the Script Does

The integration test performs the following steps:

1. Generates a temporary bamai.conf
2. Starts huatuo-bamai with mocked procfs and sysfs
3. Waits for the Prometheus /metrics endpoint to become available
4. Fetches all metrics from /metrics
5. Verifies that all expected metrics exist
6. Stops the service and cleans up resources

If any expected metric is missing, the test fails.

How to Run

Run the integration test from the project root:

bash integration/run.sh

or

make integration

On Failure

• The huatuo-bamai service metrics and logs are printed to stdout
• The temporary working directory is kept for debugging

On Success

• Output the list of successfully validated metrics

How to Add New Metrics Tests

1: Add or Update Fixture Data

If the metric depends on /proc or /sys, add or update mock data under:

integration/fixtures/

The directory structure should match the real kernel filesystem layout.

2: Add Expected Metrics

Create a new file under:

integration/fixtures/expected_metrics/
├── cpu.txt
├── memory.txt
└── ...

Each non-empty, non-comment line represents one expected Prometheus metric line and must match the /metrics output exactly.

New *.txt files are automatically picked up by the test.

3: Run the Test

bash integration/run.sh

The test fails if any expected metric is missing or mismatched.
