Instructions

When this skill is invoked:

1. Parse arguments (if provided):

   • If arguments include a feature name and/or OS, use those
   • Otherwise, proceed to interactive selection

2. Interactive selection (if no arguments or partial arguments):

   Use AskUserQuestion tool with these specific questions:

   Question 1: Feature Selection

   • Header: "Feature"
   • Question: "Which e2e test feature(s) do you want to run?"
   • multiSelect: true (allow multiple features)
   • Options:
     • basic: "Core CRC lifecycle tests - setup, start, stop, delete, version, status (~30 min)"
     • config: "Configuration management and property validation tests (~15 min)"
     • minimal: "Quick minimal test suite for fast validation (~10 min, requires MicroShift bundle)"
     • story_openshift: "OpenShift-specific features and scenarios (~45 min)"
     • story_microshift: "MicroShift-specific features and scenarios (~45 min)"
     • story_application_deployment: "Application deployment workflows (~30 min)"
     • running_cluster_tests: "Tests for running cluster operations (~20 min, requires running cluster)"
     • cert_rotation: "Certificate rotation scenarios (~25 min, Linux only)"
     • story_manpages: "Man page generation and validation (~10 min)"

   Question 2: OS Platform Selection

   • Header: "Platform"
   • Question: "Which OS platform do you want to test?"
   • multiSelect: false (single selection)
   • Options:
     • current: "Use current platform ($(GOOS)) - Recommended"
     • linux: "Linux platform (most features supported)"
     • darwin: "macOS platform (arm64 and amd64)"
     • windows: "Windows platform (amd64 only)"

   Question 3: Bundle Location

   • Header: "Bundle"
   • Question: "Where is the CRC bundle located?"
   • multiSelect: false (single selection)
   • Options:
     • cache: "~/.crc/cache/crc_*.crcbundle (CRC cache directory) - Recommended"
     • downloads: "~/Downloads/crc_*.crcbundle"
     • custom: "Specify custom path"

   Question 4: Pull Secret Location

   • Header: "Pull Secret"
   • Question: "Where is the pull secret file located?"
   • multiSelect: false (single selection)
   • Options:
     • downloads: "~/Downloads/crc-pull-secret (default) - Recommended"
     • custom: "Specify custom path"

3. Handle custom paths (if user selected "custom" for any location):

   • For each "custom" selection, the user will provide the path via "Other" option
   • Extract the custom path from the user's response
   • Validate that custom paths exist before proceeding
   • Store paths for use in environment variables

4. Build CRC from source:

   • Run make cross to build CRC binaries for all platforms
   • This will create platform-specific binaries in the out/ directory:
     • Linux AMD64: out/linux-amd64/crc
     • Linux ARM64: out/linux-arm64/crc
     • macOS AMD64: out/macos-amd64/crc
     • macOS ARM64: out/macos-arm64/crc
     • Windows AMD64: out/windows-amd64/crc.exe
   • Display build progress to user
   • Verify the binary was built successfully for the target platform

5. Determine CRC binary directory:

   • Based on the selected platform, set the binary directory:
     • If platform is "current": detect using go env GOOS and go env GOARCH
     • If platform is "linux": use --crc-binary=out/linux-amd64/
     • If platform is "darwin": detect arch with uname -m (returns arm64 or x86_64); normalize x86_64 to amd64 and use --crc-binary=out/macos-<arch>/
     • If platform is "windows": use --crc-binary=out/windows-amd64/
   • Note: CRC_BINARY should be the directory path, not including the binary name itself
   • Verify the binary exists in the determined directory (e.g., out/linux-amd64/crc or out/windows-amd64/crc.exe)

6. Prepare test environment:

   • Based on bundle location selection:
     • If "cache": list available bundles in ~/.crc/cache and let user select or provide path
     • If "downloads": list available bundles in ~/Downloads and let user select or provide path
     • If "custom": ask user for the path
   • Verify the bundle file exists at the specified location
   • Verify the pull secret file exists at the specified location
   • Inform user about any missing prerequisites

7. Clean CRC state (IMPORTANT - Required for most tests):

   • If selected features include running_cluster_tests, skip crc cleanup and verify the cluster is running (crc status) instead.
   • Otherwise, run crc cleanup using the built binary (e.g., out/linux-amd64/crc cleanup)
   • This ensures tests start with a clean state (no existing VM, no stale configuration)
   • Critical for @basic tests which expect an unconfigured system
   • Note: Cleanup may require sudo password for removing system files:
     • /etc/udev/rules.d/99-crc-vsock.rules (udev rules)
     • /etc/modules-load.d/vhost_vsock.conf (vsock module config)
   • If cleanup fails due to missing sudo access at the end of test run, it's acceptable (cleanup failure in tests is cosmetic)
   • Use absolute paths (not tilde) for bundle and pull secret locations to avoid path expansion issues

8. Build test command:

   Construct the make command as follows:

   a. Start with base: make e2e

   b. Build tag filter:

   • If platform is "current": use $(GOOS) or detect with go env GOOS
   • If single feature: --godog.tags="<os> && @<feature>"
   • If multiple features: --godog.tags="<os> && (@feature1 || @feature2 || @feature3)"
   • Always include OS tag AND feature tag(s)

   c. Build environment variables based on user selections:

   • Always set CRC_BINARY to the platform-specific binary directory from step 5 (format: --crc-binary=/absolute/path/to/out/<platform>-<arch>/)
   • For bundle location:
     • IMPORTANT: Use absolute paths (not tilde ~) to avoid path expansion issues
     • If "cache": prompt user to select specific bundle from ~/.crc/cache or set BUNDLE_LOCATION=--bundle-location=/absolute/path/to/.crc/cache/<bundle_file>
     • If "downloads": prompt user to select specific bundle from ~/Downloads or set BUNDLE_LOCATION=--bundle-location=/absolute/path/to/Downloads/<bundle_file>
     • If "custom": set BUNDLE_LOCATION=--bundle-location=<absolute_custom_path>
   • For pull secret location:
     • IMPORTANT: Use absolute paths (not tilde ~)
     • If "downloads": set PULL_SECRET_FILE=--pull-secret-file=/absolute/path/to/Downloads/crc-pull-secret
     • If "custom": set PULL_SECRET_FILE=--pull-secret-file=<absolute_custom_path>
   • Note: All environment variables must include their flag prefix and use absolute paths

   d. Combine into final command:

   CRC_BINARY=--crc-binary=<binary_dir> [OTHER_ENV_VARS] make e2e GODOG_OPTS="--godog.tags=\"<constructed_tags>\""
   

   Note: <binary_dir> is the absolute directory path (e.g., /home/user/crc/out/linux-amd64/), not the full binary path

   e. Example commands:

   # Single feature on Linux with built binary and bundle from cache (using absolute paths)
   CRC_BINARY=--crc-binary=/home/user/crc/out/linux-amd64/ BUNDLE_LOCATION=--bundle-location=/home/user/.crc/cache/crc_libvirt_4.21.8_amd64.crcbundle PULL_SECRET_FILE=--pull-secret-file=/home/user/pull-secret make e2e GODOG_OPTS="--godog.tags=\"linux && @basic\""
   
   # Multiple features on macOS with built binary
   CRC_BINARY=--crc-binary=/Users/user/crc/out/macos-arm64/ BUNDLE_LOCATION=--bundle-location=/Users/user/.crc/cache/crc_vfkit_4.21.8_arm64.crcbundle make e2e GODOG_OPTS="--godog.tags=\"darwin && (@basic || @config || @minimal)\""
   

9. Execute tests:

   • Run the test command
   • Display progress and results to user
   • Provide clear feedback on pass/fail status
   • Note: If the final test cleanup step fails due to sudo password requirement, this is acceptable
     • The test suite runs its own cleanup at the end which may fail in non-interactive environments
     • Focus on the actual test results (scenarios/steps passed), not cleanup failure
     • A test is considered successful if all scenarios passed, even if final cleanup failed

Environment Variables

These are set automatically by the skill:

• CRC_BINARY: Directory path to platform-specific CRC binary built from source (e.g., --crc-binary=/home/user/crc/out/linux-amd64/)
• PULL_SECRET_FILE: Required path to pull secret (e.g., --pull-secret-file=/home/user/pull-secret)
• BUNDLE_LOCATION: Path to CRC bundle (e.g., --bundle-location=/home/user/.crc/cache/crc_*.crcbundle)
• CLEANUP_HOME: Whether to cleanup home directory (default: not set)

Note: All environment variables include the flag prefix (e.g., --crc-binary=, --bundle-location=, --pull-secret-file=)

Example Usage

# Interactive mode
/e2e-test

# With feature argument
/e2e-test basic

# With feature and OS
/e2e-test config linux

# Multiple features
/e2e-test basic,config darwin

Important Notes

Test Duration

• Tests can take 10-180 minutes depending on feature selection
• Full test suite (@basic) typically takes ~30 minutes
• Multiple features will run sequentially

Prerequisites

• Build environment: Go toolchain and build dependencies for make cross
• Pull secret: Required at ~/Downloads/crc-pull-secret (or custom path)
• CRC bundle: Required at ~/.crc/cache/crc_.crcbundle, ~/Downloads/crc_.crcbundle, or custom path
• Clean state: Most tests expect no existing CRC cluster
• System resources: Ensure adequate RAM (16GB+ recommended for monitoring tests)
• Build time: make cross takes ~5-10 minutes to compile binaries for all platforms

Platform-Specific Considerations

• @cert_rotation only runs on Linux
• @running_cluster_tests requires a cluster to already be running
• Windows tests require .exe extension handling
• macOS supports both arm64 and amd64 architectures
• @minimal test requires MicroShift bundle (crc_microshift_*.crcbundle), not OpenShift bundle

Key Technical Notes

• Path Expansion: Always use absolute paths (e.g., /home/user/.crc/cache/...) instead of tilde paths (~/.crc/cache/...) to avoid shell expansion issues in the test framework
• Cleanup Requirements: Running crc cleanup before tests ensures clean state, especially critical for @basic tests that check for unconfigured system
• Sudo Access: Cleanup operations require sudo to remove system files (udev rules, vsock config); have password ready
• Test Cleanup Failures: If the test suite's final cleanup step fails due to sudo, it's cosmetic - focus on scenario/step pass rates

Before Running

The skill will automatically:

1. Build CRC from source using make cross
2. Verify the binary exists for the target platform
3. Check that bundle and pull secret files exist
4. Run crc cleanup to ensure clean state (may require sudo password)

The user should ensure:

1. Sudo access available (cleanup requires sudo to remove system files like udev rules)
2. Pull secret and bundle files are available (check ~/.crc/cache or ~/Downloads)
3. Adequate disk space for build artifacts (~500MB in out/ directory)
4. No active CRC cluster is running (will be cleaned up automatically)

Execution Behavior

• Build phase: make cross compiles binaries for all platforms (~5-10 minutes)
• Cleanup phase: crc cleanup removes existing CRC state (may prompt for sudo password)
• Test phase: Tests run with --timeout=180m (3 hours max)
• Output is verbose (-v flag enabled)
• Tests may modify CRC configuration
• Some tests require internet connectivity
• Failed tests will show detailed error output
• The skill always uses the freshly built binary from the out/ directory
• IMPORTANT: Always use absolute paths (not ~) for bundle and pull secret locations to avoid path expansion issues
