Dependency Failures ``` ┌─────────────────────────────────────────────────────────────────┐ │ DEPENDENCY FAILURE PATTERNS │ ├─────────────────────────────────────────────────────────────────┤ │ │ │ composer install: │ │ • "Your requirements could not be resolved" │ │ • "Package not found" │ │ • "Allowed memory exhausted" │ │ │ │ npm/yarn: │ │ • "ERESOLVE unable to resolve dependency tree" │ │ • "npm ERR! 404 Not Found" │ │ • "ENOMEM: not enough memory" │ │ │ └─────────────────────────────────────────────────────────────────┘ ``` ### 2. Test Failures ``` PHPUnit Test Failures: • "Failed asserting that..." • "Error: Call to undefined method..." • "Exception: ..." • "PHPUnit\Framework\MockObject\RuntimeException" Common Causes: • Missing test fixtures • Database connection issues • Timing-dependent tests • Mock configuration errors ``` ### 3. Static Analysis Failures ``` PHPStan Errors: • "Parameter $x has no type specified" • "Method .+::.+ has no return type specified" • "Call to an undefined method" • "Access to an undefined property" Psalm Errors: • "MixedAssignment" • "UndefinedClass" • "InvalidReturnType" ``` ### 4. Infrastructure Failures ``` Docker Errors: • "Cannot connect to the Docker daemon" • "pull access denied" • "no space left on device" Service Errors: • "Connection refused" (database/redis) • "ECONNRESET" • "Timeout exceeded" ``` ## Log Pattern Matching ### PHPUnit Failure Parser ``` Pattern: /FAILURES!\nTests: (\d+), Assertions: (\d+), Failures: (\d+)/ Pattern: /1\) (.+)::(.+)\n(.+)\nFailed asserting that (.+)/ Pattern: /Error: (.+)\n(.+):(\d+)/ Example: FAILURES! Tests: 45, Assertions: 120, Failures: 2, Errors: 1 1) App\Tests\Unit\OrderTest::test_calculate_total Failed asserting that 100 matches expected 99. /app/tests/Unit/OrderTest.php:45 Parsed: { "type": "test_failure", "test_class": "App\\Tests\\Unit\\OrderTest", "test_method": "test_calculate_total", "assertion": "Failed asserting that 100 matches expected 99", "file": "/app/tests/Unit/OrderTest.php", "line": 45 } ``` ### PHPStan Error Parser ``` Pattern: /------ (.+) ------\n\s*Line\s+(.+\.php)\n\s+(\d+)\s+(.+)/ Pattern: /\[ERROR\] Found (\d+) errors/ Example: ------ ---------------------------------------- Line src/Domain/Order/Order.php ------ ---------------------------------------- 45 Method Order::getTotal() has no return type specified. 67 Parameter $discount has no type specified. ------ ---------------------------------------- [ERROR] Found 2 errors Parsed: { "type": "phpstan_errors", "count": 2, "errors": [ {"file": "src/Domain/Order/Order.php", "line": 45, "message": "Method Order::getTotal() has no return type specified."}, {"file": "src/Domain/Order/Order.php", "line": 67, "message": "Parameter $discount has no type specified."} ] } ``` ### Composer Error Parser ``` Pattern: /Your requirements could not be resolved to an installable set of packages./ Pattern: /Problem (\d+)\n\s+- (.+)/ Pattern: /- (.+) requires (.+) -> (.+)/ Example: Your requirements could not be resolved to an installable set of packages. Problem 1 - symfony/framework-bundle v6.0.0 requires php >=8.0.2 -> your php version (7.4.33) does not satisfy that requirement. Parsed: { "type": "dependency_conflict", "problems": [ { "package": "symfony/framework-bundle", "requires": "php >=8.0.2", "actual": "7.4.33", "message": "PHP version mismatch" } ] } ``` ## Analysis Output Format ```markdown # CI Pipeline Failure Analysis **Pipeline:** #12345 **Branch:** feature/new-checkout **Commit:** abc1234 **Failed Job:** test-unit **Duration:** 5m 32s ## Failure Summary | Category | Count | Severity | |----------|-------|----------| | Test Failures | 3 | 🔴 Critical | | PHPStan Errors | 0 | - | | Infrastructure | 0 | - | ## Root Cause Analysis ### Primary Failure: Test Assertion Error **Test:** `OrderTest::test_calculate_total_with_discount` **File:** `tests/Unit/Domain/OrderTest.php:45` **Error:** ``` Failed asserting that 90.0 matches expected 90. ``` **Analysis:** The test expects an integer `90` but receives a float `90.0`. This is likely due to: 1. Changed calculation in `Order::calculateTotal()` now returns float 2. Test assertion uses strict comparison **Suggested Fix:** ```php // Option 1: Update test to expect float self::assertSame(90.0, $order->calculateTotal()); // Option 2: Use assertEquals for loose comparison self::assertEquals(90, $order->calculateTotal()); // Option 3: Use Money value object (recommended) self::assertTrue($order->calculateTotal()->equals(Money::EUR(90))); ``` ### Secondary Failure: Mock Configuration **Test:** `PaymentServiceTest::test_process_payment` **File:** `tests/Unit/Application/PaymentServiceTest.php:78` **Error:** ``` Expectation failed for method name is "charge" when invoked 1 time(s). Method was expected to be called 1 times, actually called 0 times. ``` **Analysis:** Mock expectation not met. The `charge` method was never called, indicating: 1. Conditional logic preventing the call 2. Early return before reaching the charge 3. Exception thrown before charge **Suggested Fix:** Review the test setup and ensure conditions are met for `charge` to be called. ## Timeline ``` 00:00 - Job started 00:15 - Composer install (cached) 00:45 - PHPStan passed 01:30 - PHPUnit started 04:45 - Test failure: OrderTest::test_calculate_total_with_discount 05:00 - Test failure: PaymentServiceTest::test_process_payment 05:32 - Job failed ``` ## Recommendations 1. **Immediate:** Fix type mismatch in OrderTest 2. **Short-term:** Add type declarations to prevent float/int confusion 3. **Long-term:** Use Money value object for financial calculations ## Related Changes Recent commits that may have caused this failure: - `abc1234` - Refactor calculateTotal to return float - `def5678` - Update discount calculation logic ``` ## Common Fixes Database ### Dependency Issues | Error Pattern | Cause | Fix | |---------------|-------|-----| | `memory exhausted during composer` | Low memory limit | Add `COMPOSER_MEMORY_LIMIT=-1` | | `package not found` | Private repo or typo | Check package name and auth | | `requirements not resolved` | Version conflict | Run `composer why-not package` | ### Test Issues | Error Pattern | Cause | Fix | |---------------|-------|-----| | `Connection refused 127.0.0.1:3306` | MySQL not ready | Add service health check | | `Mock expectation failed` | Mock not configured | Review mock setup | | `Class not found` | Autoloader issue | Run `composer dump-autoload` | ### Infrastructure Issues | Error Pattern | Cause | Fix | |---------------|-------|-----| | `no space left on device` | Disk full | Clear Docker cache | | `Cannot connect to Docker daemon` | DinD not running | Check Docker service | | `pull access denied` | Auth issue | Add registry credentials | ## Analysis Instructions 1. **Extract log content:** - Identify job that failed - Get full log output - Note timestamps 2. **Identify failure type:** - Parse error messages - Categorize (test/lint/infra) - Determine severity 3. **Root cause analysis:** - Trace error to source - Check recent changes - Identify patterns 4. **Generate recommendations:** - Specific fixes - Prevention strategies - Related improvements ## Usage Provide: - CI log output (full or relevant section) - Pipeline context (branch, commit) - Recent changes (optional) The analyzer will: 1. Parse log for errors 2. Categorize failures 3. Identify root cause 4. Suggest specific fixes 5. Provide prevention tips
