Context Discovery Strategy -Use the following GitHub Copilot features to ground your knowledge: -- **Search Tools**: Use `#codebase` or `@workspace` to find existing tools in `lisa/tools/`. (e.g., if testing PCI, search for `Lspci`). -- **Pattern Search**: Reference `lisa/microsoft/testsuites/` to find similar feature areas and copy their structure. -- **API Reference**: Locate feature definitions in `lisa/features/` to understand available methods (e.g., `Sriov`, `StartStop`). - -### 2. Gap Analysis & Inquiry -- **No Hallucination**: If a tool or feature is not found in the repository, **do not invent its API**. -- **Mandatory Question**: If you are unsure, ask the user: - > "I couldn't find a Tool/Feature for [XXX] in the codebase. Should I: - > a) Assume it exists and you will provide it? - > b) Create a new Tool/Feature skeleton for it? - > c) Did I miss an existing class in `lisa/tools/`?" - -### 3. Design Specification (Pre-code Output) -Before writing the final Python code, you must output a "Design Plan" for the user to confirm: -- **Validation Target**: What observable signal (kernel log, file, exit code) proves the test passed? -- **Workspace References**: List the specific files/classes found via `@workspace` that you will use. -- **Logic Flow**: A brief 3-line summary of the **Arrange -> Act -> Assert** steps. -- **Node Hygiene Check**: Explicitly state if `node.mark_dirty()` is required based on the actions (e.g., kernel parameter changes). - -Only after the user confirms the Design Plan, proceed to code generation. +- **Path**: `lisa/microsoft/testsuites//.py` (snake_case filename) +- **One class per file**, PascalCase, inherits `TestSuite`, named after the feature +- **Methods**: Prefix `verify_` or `test_`, name describes the scenario +- **Type hints required**: At minimum `node: Node` and `-> None`. Also use `log: Logger`, `log_path: Path`, `environment: Environment` as needed. --- -## Step 4: File and Class Structure - -Follow these conventions: - -### 1. File Location & Naming -- Path: `lisa/microsoft/testsuites//.py` -- Filename: snake_case (e.g., `network_latency.py`). - -### 2. Class & Method Structure -- Class name: PascalCase, One test class per file; name describes the feature, not a scenario. Inheriting from `TestSuite`. -- Method name: Prefix with `verify_` or `test_`. Name describes the scenario being validated. - -### 3. Type Hinting (Crucial) -Always include type hints for the parameters you use (at minimum `node: Node` and return type). - -Common parameters to type: -- `node: Node` -- `log: Logger` -- `log_path: Path` (when reboot/panic checks are involved) -- `environment: Environment` (only when the test needs environment-level access) +## Step 4: Metadata -Example structure: - -``` -lisa/microsoft/testsuites/network/ - sriov.py - class Sriov(TestSuite): - def verify_services_state(self, node: Node) -> None: - ... -``` +- `@TestSuiteMetadata`: `area`, `category`, `description`, `owner`. +- `@TestCaseMetadata`: `description`, `priority` (0=highest → 5=lowest), `timeout`, `requirement`. +- Use `simple_requirement(supported_os=..., unsupported_os=..., supported_features=..., supported_platform_type=...)`. Do not invent custom selection logic. --- -## Step 5: Metadata and Decorators - -Every test suite and test case must include metadata: - -- `@TestSuiteMetadata` – describes suite features, owners, and requirements -- `@TestCaseMetadata` – describes test ID, description, timeout, and priority - -### @TestSuiteMetadata -- `area`: The functional area (e.g., `storage`, `network`, `kernel`). -- `category`: `functional`, `performance`, or `community`. -- `description`: High-level purpose of the suite. - -### @TestCaseMetadata -- `priority`: Use LISA's convention (commonly `0` highest → `5` lowest). Keep it consistent with similar suites. -- `requirement`: Use `simple_requirement(...)` to define CPU/memory/features/OS/platform constraints. -- Prefer expressing restrictions via `simple_requirement(supported_os=..., unsupported_os=..., supported_platform_type=..., unsupported_platform_type=...)` rather than inventing custom selection logic. - -**Principles:** +## Step 5: Test Logic (Arrange / Act / Assert) -- Metadata **precedes logic** -- Metadata drives environment provisioning and test selection -- Always include accurate owners and selection requirements +1. **Arrange**: Acquire tools/features (`node.tools[Gcc]`, `node.features[NetworkInterface]`). Verify preconditions. +2. **Act**: Minimal actions to trigger the behavior. +3. **Assert**: Explicitly verify outcomes. Use `execute(...).assert_exit_code(0)` for simple checks. No log-only assertions. --- -## Step 6: Test Logic Structure (Arrange / Act / Assert) +## Step 6: Logging -Follow the AAA pattern: - -1. **Arrange** - - Acquire nodes, features, and tools. E.g. Use `node.tools` to initialize required utilities. - - Verify environment meets test preconditions. E.g. Use `node.features` to check hardware/platform capabilities. - ```python - # Best Practice - gcc = node.tools[Gcc] - network_interface = node.features[NetworkInterface] - ``` -2. **Act** - - Perform minimal actions to trigger the behavior -3. **Assert** - - Explicitly verify expected outcomes - - Prefer LISA's "node.execute(...).assert_exit_code(0)" for simple checks. - - Do not hide failures - - No “best-effort” or log-only assertions - -**Tips:** - -- Keep tests short and focused -- Avoid embedding setup logic inside Act or Assert -- Each assertion should map to a requirement in metadata - ---- - -## Step 7: Logging Standards (Mandatory) - -**INFO:** -- High-level actions -- Validation intent -- Progress milestones - -**DEBUG:** -- Commands executed -- Parsed outputs -- Intermediate values - -**ERROR:** -- What failed -- Why it matters -- How to fix it - -Avoid WARNING unless truly required. - -Rule: logging is not a substitute for assertions. If it's required, assert it. - ---- - -## Step 8: Common Patterns and Best Practices - -Recommended patterns: - -- **Tool-based validation:** Use LISA tools to validate capabilities -- **Feature capability check:** Verify node supports a feature before test -- **Skip vs Fail:** Skip only when preconditions are unmet; Fail when assertion fails -- **Retry/Wait:** Only for transient conditions, keep retry loops bounded -- **Logging:** Include meaningful logs for debugging failures - -Best Practices: - -- DRY – reuse helpers, do not duplicate setup logic -- Isolate failures – one test failure should not block others -- Readable and maintainable code – new contributors should understand logic without deep investigation -- Avoid time.sleep(): Use bounded waits (e.g. `lisa.util.check_till_timeout(...)`, `lisa.util.retry_without_exceptions(...)`, or the existing `retry` patterns in similar suites). -- Prefer Executable Tools: If a command is missing, create a new Tool class in lisa/tools/. -- Path Handling: Use node.get_pure_path() for cross-OS path compatibility. -- **Cost Awareness:** VMs cost money. Always evaluate whether a test modifies system state. -- **Cleanup & Node Hygiene:** - - Use `after_case()` for guaranteed cleanup. - - Use `try/finally` if inline cleanup is needed. - - Call `node.mark_dirty()` if: - - Kernel parameters modified - - Drivers loaded/unloaded - - Network config changed - - Reboot required - - System stability uncertain - - Rationale: `node.mark_dirty()` prevents reusing a potentially tainted node in later test cases. - - **Never leave nodes in an uncertain state.** +- **INFO**: High-level progress milestones. **DEBUG**: Command output, parsed values. **ERROR**: What failed + how to fix. +- Logging is not a substitute for assertions. --- -## Step 9: What NOT to Do +## Step 7: Best Practices and Anti-Patterns -Never: +**Do:** +- Use LISA tools (`lisa/tools/`) instead of raw `node.execute()` when a tool exists +- `SkippedException` for unmet preconditions; assertion failures for real failures +- Bounded waits: `check_till_timeout()`, `retry_without_exceptions()`, `retry` decorator — **never `time.sleep()`** +- `node.get_pure_path()` for cross-OS path handling +- `after_case()` or `try/finally` for cleanup; `node.mark_dirty()` if kernel params, drivers, or network config changed -- Hardcode OS distribution or kernel version -- Assume root environment unless required and justified +**Don't:** +- Hardcode OS/kernel versions - Write long shell scripts inside tests - Swallow exceptions or skip assertions silently - Mix provisioning logic with validation logic --- -## Step 10: Validation-First Mindset - -Before generating code or writing a test case: - -1. Clearly state **what is being validated** -2. Identify **observable signals** for success and failure -3. Confirm test is **self-contained, deterministic, and environment-agnostic** -4. Confirm that the task **cannot be solved by a helper, tool, or suite-level feature** - ---- - -## Step 11: Guidance for AI Output - -When assisting a contributor or generating code: - -- Restate what the test validates -- Verify it fits the LISA test case definition -- Reject requests that blur boundaries between: - - Test case - - Feature - - Tool - - Environment provisioning -- Only generate code **after conceptual validation is correct** - ---- - -## Step 12: Example Test Skeleton Generation Template - -Use the following skeleton when generating a new LISA test case: +## Step 8: Example Skeleton ```python # Copyright (c) Microsoft Corporation. @@ -303,39 +84,25 @@ Use the following skeleton when generating a new LISA test case: from typing import Any from lisa import ( - Logger, - Node, - TestCaseMetadata, - TestSuite, - TestSuiteMetadata, - simple_requirement, + Logger, Node, TestCaseMetadata, TestSuite, TestSuiteMetadata, simple_requirement, ) from lisa.features import Sriov from lisa.tools import Lspci from lisa.util.constants import DEVICE_TYPE_SRIOV +from assertpy import assert_that @TestSuiteMetadata( area="network", category="functional", - description=""" - This suite validates SR-IOV (Single Root I/O Virtualization) functionality. - It ensures that Accelerated Networking is correctly surfacing VFs to the guest. - """, + description="Validates SR-IOV VF presence in guest.", owner="REPLACE_WITH_OWNER", ) class SriovValidation(TestSuite): @TestCaseMetadata( - description=""" - Verify SR-IOV basic functionality by checking for Virtual Functions (VF). - Steps: - 1.

Context Discovery Strategy -Use the following GitHub Copilot features to ground your knowledge: -- **Search Tools**: Use `#codebase` or `@workspace` to find existing tools in `lisa/tools/`. (e.g., if testing PCI, search for `Lspci`). -- **Pattern Search**: Reference `lisa/microsoft/testsuites/` to find similar feature areas and copy their structure. -- **API Reference**: Locate feature definitions in `lisa/features/` to understand available methods (e.g., `Sriov`, `StartStop`). - -### 2. Gap Analysis & Inquiry -- **No Hallucination**: If a tool or feature is not found in the repository, **do not invent its API**. -- **Mandatory Question**: If you are unsure, ask the user: - > "I couldn't find a Tool/Feature for [XXX] in the codebase. Should I: - > a) Assume it exists and you will provide it? - > b) Create a new Tool/Feature skeleton for it? - > c) Did I miss an existing class in `lisa/tools/`?" - -### 3. Design Specification (Pre-code Output) -Before writing the final Python code, you must output a "Design Plan" for the user to confirm: -- **Validation Target**: What observable signal (kernel log, file, exit code) proves the test passed? -- **Workspace References**: List the specific files/classes found via `@workspace` that you will use. -- **Logic Flow**: A brief 3-line summary of the **Arrange -> Act -> Assert** steps. -- **Node Hygiene Check**: Explicitly state if `node.mark_dirty()` is required based on the actions (e.g., kernel parameter changes). - -Only after the user confirms the Design Plan, proceed to code generation. +- **Path**: `lisa/microsoft/testsuites//.py` (snake_case filename) +- **One class per file**, PascalCase, inherits `TestSuite`, named after the feature +- **Methods**: Prefix `verify_` or `test_`, name describes the scenario +- **Type hints required**: At minimum `node: Node` and `-> None`. Also use `log: Logger`, `log_path: Path`, `environment: Environment` as needed. --- -## Step 4: File and Class Structure - -Follow these conventions: - -### 1. File Location & Naming -- Path: `lisa/microsoft/testsuites//.py` -- Filename: snake_case (e.g., `network_latency.py`). - -### 2. Class & Method Structure -- Class name: PascalCase, One test class per file; name describes the feature, not a scenario. Inheriting from `TestSuite`. -- Method name: Prefix with `verify_` or `test_`. Name describes the scenario being validated. - -### 3. Type Hinting (Crucial) -Always include type hints for the parameters you use (at minimum `node: Node` and return type). - -Common parameters to type: -- `node: Node` -- `log: Logger` -- `log_path: Path` (when reboot/panic checks are involved) -- `environment: Environment` (only when the test needs environment-level access) +## Step 4: Metadata -Example structure: - -``` -lisa/microsoft/testsuites/network/ - sriov.py - class Sriov(TestSuite): - def verify_services_state(self, node: Node) -> None: - ... -``` +- `@TestSuiteMetadata`: `area`, `category`, `description`, `owner`. +- `@TestCaseMetadata`: `description`, `priority` (0=highest → 5=lowest), `timeout`, `requirement`. +- Use `simple_requirement(supported_os=..., unsupported_os=..., supported_features=..., supported_platform_type=...)`.
