# Run the Test Suite and Triage Failures in Symfony with Atlas in 2026 > Atlas helps Symfony developers in 2026 turn overwhelming `PHPUnit (WebTestCase)` output into a prioritized list of distinct root causes for efficient bug resolution. Atlas empowers Symfony developers in 2026 to efficiently triage a wall of red `PHPUnit (WebTestCase)` output, transforming it into a prioritized list of distinct root causes. By leveraging Atlas's `bash` tool to run `bin/phpunit` and then `grep` to group failures, you can quickly identify and address issues within your Symfony application, ensuring a more robust and maintainable codebase. ## Key takeaways - Atlas uses `bash` to run `bin/phpunit` for Symfony test suites, capturing all output. - Full `PHPUnit` logs are saved and accessible via `atlas read`, even if truncated in the terminal. - `atlas grep` helps identify distinct root causes in Symfony test failures, not just individual test names. - `atlas todowrite` tracks fixes for identified Symfony issues, ensuring systematic resolution. - Atlas's `edit` tool and unified diff review ensure safe, controlled changes to Symfony code. - `PHP-CS-Fixer` can be integrated via `atlas bash` for consistent code style in Symfony projects. ## How to Run Symfony PHPUnit WebTestCase with Atlas's Bash Tool Atlas simplifies running your `PHPUnit (WebTestCase)` suite in 2026 by integrating directly with your terminal. Use Atlas's `bash` tool to execute `bin/phpunit`, ensuring a generous timeout of 300000 milliseconds (5 minutes) to prevent premature termination of slow test runs. This approach captures all output for later analysis. To initiate a full test run within your Symfony application, Atlas provides its `bash` tool, allowing you to execute native shell commands. For `PHPUnit (WebTestCase)`, the command is straightforward: `atlas bash "bin/phpunit --testsuite=WebTestCase --timeout=300000"`. This command targets the `WebTestCase` suite, common in Symfony for functional and integration tests, and sets a substantial timeout to accommodate complex or slow-running test cases. Atlas runs this command in the context of your project, where `composer.json` defines your dependencies and `bin/phpunit` is available. The entire output, regardless of length, is captured by Atlas for subsequent analysis, ensuring no failure detail is lost. ## Accessing Complete Symfony Test Logs Beyond Truncated Output When your Symfony test suite generates extensive output, Atlas's `bash` tool intelligently truncates it at 2000 lines or 50 KB in the terminal, but always saves the complete log. Atlas provides the full path to this retained file, allowing you to access every detail of your `PHPUnit (WebTestCase)` failures for comprehensive analysis. A common challenge with large Symfony test suites is the sheer volume of output, which can overwhelm standard terminal buffers. Atlas addresses this by truncating the visible output in the terminal to a manageable 2000 lines or 50 KB. Crucially, Atlas writes the complete, untruncated log to a temporary file and provides its path in the `...output truncated...` header. To review the entire `PHPUnit (WebTestCase)` output, simply use `atlas read `. This ensures you have access to every stack trace, error message, and detail, which is vital for accurate triage of complex Symfony application failures. ## Grouping Symfony PHPUnit Failures by Root Cause with Atlas Grep Instead of sifting through individual `PHPUnit (WebTestCase)` failures, Atlas helps you group them by distinct root causes using its `grep` tool. This method, effective in 2026, allows you to quickly identify common underlying problems across your Symfony application, rather than getting bogged down by numerous test names. The goal of triage is to identify distinct root causes, not just a list of failing tests. After running your `PHPUnit (WebTestCase)` suite and accessing the full log, use Atlas's `grep` tool to find patterns indicative of underlying issues. For example, `atlas grep "Doctrine\ORM\ORMException" ` can quickly show all failures related to a specific Doctrine ORM problem. Similarly, searching for custom exception messages or common error patterns in your Symfony services or controllers helps consolidate many individual test failures into a few actionable root causes. This approach transforms a daunting wall of red into a manageable list of distinct problems to address. ## Tracking and Fixing Symfony Issues with Atlas Todowrite Once distinct root causes are identified in your Symfony application, Atlas helps you track them effectively. Use the `todowrite` tool to record each unique issue as a pending task, ensuring that no identified `PHPUnit (WebTestCase)` failure is forgotten. This structured approach streamlines your debugging workflow in 2026. After grouping `PHPUnit (WebTestCase)` failures by root cause using `grep`, the next step is to formalize these findings into actionable tasks. Atlas's `todowrite` tool is designed for this. For each distinct root cause, create a new entry: `atlas todowrite "Fix: [Description of Symfony service misconfiguration]" --status=pending`. This creates a persistent record of the issue, its status, and allows you to focus on one problem at a time. This is particularly useful when dealing with complex Symfony applications involving multiple bundles, the service container, or Doctrine entities, ensuring a systematic approach to resolving test failures. ## Ensuring Safe Symfony Code Changes with Atlas's Review Process Atlas prioritizes safety and transparency when making changes to your Symfony codebase. Every proposed edit, whether to a controller or a Doctrine entity, generates a unified diff for your approval before writing, and Atlas can snapshot file changes as git patches, offering robust rollback capabilities in 2026. When Atlas proposes a fix for a `PHPUnit (WebTestCase)` failure, it operates with a strong emphasis on user control and safety. Before any file is modified, Atlas drafts a plan in a read-only agent and asks for your approval. All tool calls are permission-gated, allowing you to `allow`, `ask`, or `deny` execution. For every suggested edit, Atlas computes a unified diff, clearly showing the proposed changes to your Symfony controllers, services, or configuration files like `config/services.yaml`. You must approve this diff before Atlas writes to disk. Furthermore, Atlas integrates with Git, reading branches, status, and diffs, and can snapshot file changes as git patches, providing a robust mechanism for reviewing and rolling back any unintended modifications. ## Steps 1. Initialize Atlas in your Symfony project, ensuring it can read your `composer.json` and `config/services.yaml`. 2. Run the full `PHPUnit (WebTestCase)` suite using `atlas bash "bin/phpunit --testsuite=WebTestCase --timeout=300000"` to capture all test output. 3. If the terminal output was truncated, use `atlas read ` to review the complete `PHPUnit` output log. 4. Group distinct failure causes by using `atlas grep "specific error message or exception type" ` over the saved log file. 5. Record each distinct root cause as a pending task with `atlas todowrite "Fix: [Root Cause Description for Symfony issue]" --status=pending`. 6. Use `atlas edit ` to implement the fix for a specific root cause in your Symfony code. 7. Re-run only the relevant `PHPUnit` tests, for example, `atlas bash "bin/phpunit tests/Controller/MyControllerTest.php"`, to verify the fix. 8. After fixing, apply `PHP-CS-Fixer` to maintain code style: `atlas bash "vendor/bin/php-cs-fixer fix src/"` over the diff. 9. Review and approve Atlas's proposed changes via the unified diff before writing them to your Symfony codebase. ## FAQ ### How do I run my Symfony PHPUnit tests with Atlas?
