Set a breakpoint by clicking left of a line number -2. Select "Smoke Tests" launch configuration -3. Press F5 -4. The Extension Host window opens -5. Tests start running -6. Execution pauses at your breakpoint -7. Use the Debug toolbar to step through code: - - **F10**: Step Over (next line) - - **F11**: Step Into (enter function) - - **Shift+F11**: Step Out (exit function) - - **F5**: Continue (to next breakpoint) - -### Viewing Variables - -While paused at a breakpoint: -- **Variables panel**: Shows local/global variables -- **Watch panel**: Add expressions to monitor -- **Debug Console**: Evaluate expressions (type `extension.isActive` and press Enter) - -### Debug Console Commands - -While debugging, you can run JavaScript in the Debug Console: - -```javascript -// Check extension state -vscode.extensions.getExtension('ms-python.vscode-python-envs') - -// List all commands -vscode.commands.getCommands().then(cmds => console.log(cmds.filter(c => c.includes('python')))) - -// Check workspace -vscode.workspace.workspaceFolders -``` - -### Common Debugging Scenarios - -#### Test Times Out - -1. Check if the test is waiting for a condition that's never met -2. Add logging to see what state the extension is in: - ```typescript - console.log('Extension active?', extension.isActive); - ``` -3. Verify the timeout is long enough for your machine - -#### Extension Not Found - -1. Verify the extension ID matches `package.json` -2. Check the build completed without errors -3. Ensure `preLaunchTask` ran successfully - ---- - -## Writing Effective Assertions - -### Principle: Be Specific - -❌ **Bad**: Vague assertion -```typescript -assert.ok(result); // What should result be? -``` - -✅ **Good**: Specific assertion with context -```typescript -assert.ok( - extension !== undefined, - `Extension ${ENVS_EXTENSION_ID} is not installed. ` + - 'Check that the extension ID matches package.json.' -); -``` - -### Assertion Patterns - -#### 1. Existence Checks - -```typescript -// Check something exists -assert.ok( - extension !== undefined, - 'Extension should be installed' -); - -// Check something is truthy -assert.ok( - api.getEnvironments, - 'API should have getEnvironments method' -); -``` - -#### 2. Equality Checks - -```typescript -// Strict equality (type + value) -assert.strictEqual( - extension.isActive, - true, - 'Extension should be active' -); - -// Deep equality (for objects/arrays) -assert.deepStrictEqual( - result.errors, - [], - 'Should have no errors' -); -``` - -#### 3. Array Membership - -```typescript -const commands = await vscode.commands.getCommands(); -assert.ok( - commands.includes('python-envs.create'), - 'create command should be registered' -); -``` - -#### 4. Failure Cases - -```typescript -try { - await riskyOperation(); - assert.fail('Should have thrown an error'); -} catch (error) { - assert.ok( - error.message.includes('expected'), - `Error message should be descriptive: ${error.message}` - ); -} -``` - -### Error Message Guidelines - -1. **State what was expected**: "Extension should be active" -2. **State what happened**: "but isActive is false" -3. **Suggest a fix**: "Check that activation completed" - -```typescript -assert.strictEqual( - extension.isActive, - true, - `Extension should be active after calling activate(), ` + - `but isActive is ${extension.isActive}. ` + - `Ensure the extension's activate() function resolves successfully.` -); -``` - ---- - -## Preventing Flakiness - -Flaky tests pass sometimes and fail sometimes. They're the #1 cause of distrust in test suites. - -### The Golden Rule: Never Use Sleep for Assertions - -❌ **Wrong**: Arbitrary delays -```typescript -await sleep(5000); // Hope 5 seconds is enough? -assert.ok(extension.isActive); -``` - -✅ **Right**: Wait for actual condition -```typescript -await waitForCondition( - () => extension.isActive, - 30_000, - 'Extension did not activate within 30 seconds' -); +### 5. Run Specific Test +```bash +npm run smoke-test -- --grep "Extension activates" ``` -### Use `waitForCondition()` for Everything Async - +Or add `.only` in code: ```typescript -// Wait for file to exist -await waitForCondition( - async () => { - try { - await vscode.workspace.fs.stat(uri); - return true; - } catch { - return false; - } - }, - 10_000, - 'File was not created' -); - -// Wait for environments to be discovered -await waitForCondition( - async () => { - const envs = await api.getEnvironments(); - return envs.length > 0; - }, - 60_000, - 'No environments discovered' -); -``` - -### Flakiness Sources and Fixes - -| Source | Problem | Fix | -|--------|---------|-----| -| **Timing** | Test assumes operation completes instantly | Use `waitForCondition()` | -| **Order** | Tests depend on each other | Make tests independent | -| **State** | Previous test left state | Clean up in `teardown()` | -| **Resources** | File locked by other process | Use unique temp files | -| **Network** | API call sometimes slow | Increase timeout, add retry | - -### Timeout Guidelines - -- **Simple operations**: 10 seconds -- **Extension activation**: 30-60 seconds -- **Environment discovery**: 60-120 seconds -- **CI environments**: 2x local timeouts - -### Built-in Retry - -The smoke test runner retries failed tests once: - -```javascript -// In src/test/smoke/index.ts -mocha.setup({ - retries: 1, // Retry failed tests once -}); +test.only('Extension activates', async function () { ... }); ``` -This handles transient failures but shouldn't be relied upon for consistently flaky tests. - ---- - -## Smoke Test Architecture +## File Structure -### File Structure - -``` -src/test/ -├── smoke/ -│ ├── index.ts # Test runner entry point -│ ├── activation.smoke.test.ts # Activation tests -│ └── [feature].smoke.test.ts # Add more test files here -├── testUtils.ts # Shared utilities (waitForCondition, etc.) -└── constants.ts # Test constants and flags ``` - -### How It Works - -1. **VS Code starts**: A new VS Code window (Extension Host) launches -2. **Extension loads**: Your extension activates in that window -3. **Tests run**: Mocha executes test files matching `*.smoke.test.ts` -4. **Results reported**: Pass/fail status shown in console - -### Environment Detection - -```typescript -import { IS_SMOKE_TEST } from './constants'; - -if (IS_SMOKE_TEST) { - // Running as smoke test - use real APIs -} else { - // Not a smoke test - might be unit test with mocks -} +src/test/smoke/ +├── index.ts # Test runner entry point +│ # - Sets VSC_PYTHON_SMOKE_TEST=1 +│ # - Configures Mocha (timeout, retries) +│ # - Finds *.smoke.test.js files +│ +└── activation.smoke.test.ts # Test file + # - Suite: "Smoke: Extension Activation" + # - Tests: installed, activates, exports, commands ``` -### Adding a New Smoke Test +### Naming Convention +- Files: `*.smoke.test.ts` +- Suites: `suite('Smoke: [Feature Name]', ...)` +- Tests: Descriptive of what's being verified -1.
