HyperFleet E2E

Black-box end-to-end testing for validating the HyperFleet cluster lifecycle management.

Go Version License

What is it?

HyperFleet E2E is a Ginkgo-based testing framework that validates HyperFleet cluster lifecycle management through black-box tests. It creates ephemeral test clusters for each test, providing complete isolation and supporting parallel execution.

Quick Start

# Clone and build
git clone https://github.com/openshift-hyperfleet/hyperfleet-e2e.git
cd hyperfleet-e2e
make build

# Set API URL and run tests
export HYPERFLEET_API_URL=https://api.hyperfleet.example.com
./bin/hyperfleet-e2e test --label-filter=tier0

Done! The framework created a cluster, validated adapters, and cleaned up resources.

Running Tests

Filter by Labels

# Critical severity tests (Release gate)
./bin/hyperfleet-e2e test --label-filter=tier0

# Exclude slow tests
./bin/hyperfleet-e2e test --label-filter="!slow"

Common Options

# Debug mode (API calls and framework internals)
./bin/hyperfleet-e2e test --log-level=debug

# Run specific test suite
./bin/hyperfleet-e2e test --focus "\[Suite: cluster\]"

Run ./bin/hyperfleet-e2e test --help for all options.

Configuration

Configuration priority (highest to lowest):

  1. CLI flags (--api-url)
  2. Environment variables (HYPERFLEET_API_URL)
  3. Config file (configs/config.yaml)
  4. Built-in defaults

Example:

export HYPERFLEET_API_URL=https://staging.api.example.com
./bin/hyperfleet-e2e test

See configs/config.yaml for all configuration options with detailed comments.

Key Features

  • Ephemeral Resources: Each test creates and cleans up its own cluster for complete isolation
  • Payload Templates: Dynamic resource naming with template variables to prevent naming conflicts
  • Flexible Filtering: Run tests by labels, focus patterns, or skip patterns
  • Comprehensive Validation: Verifies cluster phases, adapter conditions, and health status
  • Structured Logging: JSON or text logging with configurable levels
  • Parallel Execution: Full isolation enables safe parallel test runs

Documentation

CI/CD Integration
