Atlas helps SQL developers in 2026 transform a wall of red `pgTAP` test output into a prioritized list of distinct root causes by leveraging its `bash` tool to run tests, `grep` to identify patterns in full logs, and `todowrite` to track fixes. This workflow ensures efficient debugging and resolution of issues within `Flyway migrations` and other SQL codebases.
How to Run pgTAP Tests with Atlas's Bash Tool for SQL
Atlas's `bash` tool in 2026 executes `pgTAP` tests, handling extensive output by truncating at 2000 lines or 50 KB and saving the complete log to a retained file. This ensures SQL developers always have the full context for debugging complex `t/*.sql` test suites.
When a SQL developer needs to run their `pgTAP` test suite, Atlas's `bash` tool provides the execution environment. For instance, to run all `pgTAP` tests located in the `t/` directory, the command would be `atlas bash "pg_prove -v t/*.sql" --timeout 60000`. The `--timeout` flag is crucial for slow-running SQL test suites, preventing Atlas from prematurely killing the process. A key capability for SQL developers is Atlas's handling of verbose output: while the terminal display is truncated at 2000 lines or 50 KB, Atlas writes the complete `pgTAP` log to a separate file. The path to this file is provided in the `...output truncated...` header, allowing SQL developers to access the entire test output for thorough analysis, which is essential when debugging intricate database logic or `Flyway migrations`.
Grouping SQL Test Failures by Root Cause with Atlas Grep
To efficiently triage SQL test failures, Atlas leverages the `grep` tool to group distinct root causes from the complete `pgTAP` log file, rather than relying on truncated terminal output. This method is vital for identifying patterns across many failing `t/*.sql` tests in 2026.
After running a `pgTAP` test suite, SQL developers often face a 'wall of red' output. Instead of sifting through individual test failures, Atlas encourages grouping by root cause. Using `atlas grep` on the complete `pgTAP` log file (obtained from the `bash` tool's output) allows developers to find common error messages or stack traces. For example, `atlas grep "ERROR: duplicate key value" /tmp/atlas_pgtap_log_12345.txt` can quickly identify all `pgTAP` tests failing due to a specific unique constraint violation, potentially pointing to an issue in a `Flyway migration` like `V3__add_unique_constraint.sql`. This approach helps SQL developers prioritize fixes by addressing the underlying problem that affects multiple tests, rather than fixing symptoms one test at a time.
Tracking SQL Fixes with Atlas's Todowrite Tool
Atlas's `todowrite` tool allows SQL developers to record each distinct root cause identified from `pgTAP` failures as a pending task, ensuring that every fix is tracked and prioritized. This structured approach prevents issues from being forgotten amidst complex `Flyway migrations` in 2026.
Once distinct root causes for `pgTAP` failures have been identified using `atlas grep`, the next step for SQL developers is to create an actionable plan. Atlas's `todowrite` tool is designed for this purpose. For each unique root cause, a new `todowrite` entry can be created with a `pending` status. For example, `atlas todowrite "Fix missing index on users.email in V2__add_email_index.sql" --status pending` creates a clear task. This transforms the overwhelming list of `pgTAP` failures into a manageable, prioritized list of fixes. By tracking these entries, SQL developers ensure that every identified issue, whether it's a bug in a stored procedure or an error in a `Flyway migration`, is addressed systematically and not overlooked.
Iterative SQL Debugging and Refinement with Atlas Edit
In 2026, Atlas's `edit` tool facilitates an iterative debugging process for SQL developers, allowing them to modify `Flyway migrations` or `t/*.sql` test files and re-run only affected `pgTAP` tests. This focused approach accelerates the resolution of identified root causes.
After identifying a root cause and creating a `todowrite` entry, SQL developers use Atlas's `edit` tool to implement the fix. For instance, if a `pgTAP` failure points to an issue in `V1__create_users_table.sql`, the developer can open and modify it with `atlas edit V1__create_users_table.sql`. Once the change is made, instead of re-running the entire `pgTAP` suite, Atlas enables developers to re-run only the affected tests using `atlas bash "pg_prove -v t/user_table_tests.sql"`. This rapid feedback loop is invaluable for SQL development, allowing for quick verification of fixes and minimizing the time spent waiting for a full test suite to complete. This iterative process is key to efficiently resolving issues in complex SQL codebases.
Reviewing SQL Changes with Atlas's Unified Diff and Git Integration
Atlas ensures safety and transparency for SQL developers by computing a unified diff for every file edit, such as changes to `Flyway migrations` or `t/*.sql` test files, and surfacing it for approval before writing. This process, integrated with Git, allows for meticulous review of all proposed changes in 2026.
Before any changes to SQL files, whether they are `Flyway migrations`, `pgTAP` test scripts, or complex queries, are permanently applied, Atlas provides a crucial safety net. It computes a unified diff for every proposed edit and presents it to the SQL developer for explicit approval. This means that modifications made via `atlas edit` are never written to disk without review. Furthermore, Atlas integrates direct with Git, allowing developers to stage and create commits directly. It also snapshots file changes as Git patches, providing a robust mechanism to diff edits and roll back if necessary. This comprehensive review and version control system is paramount for maintaining the integrity and stability of SQL schemas and applications.
Step by step
- 01Run your `pgTAP` test suite using Atlas's `bash` tool, providing a generous timeout to accommodate slow SQL tests: `atlas bash "pg_prove -v t/*.sql" --timeout 90000`.
- 02If the `pgTAP` output was truncated, use `atlas read` to view the complete log file path provided in the `...output truncated...` header for full SQL context.
- 03Group `pgTAP` failures by distinct root cause using `atlas grep` on the saved log file, focusing on error messages rather than individual test names. Example: `atlas grep "ERROR: foreign key violation" /tmp/atlas_pgtap_log_12345.txt`.
- 04Record each distinct root cause as a pending task using `atlas todowrite`, creating an actionable list of SQL fixes. Example: `atlas todowrite "Fix missing foreign key in V4__add_orders_table.sql" --status pending`.
- 05Use `atlas edit` to modify the relevant SQL file, such as a `Flyway migration` (`V4__add_orders_table.sql`) or a `pgTAP` test file (`t/orders_tests.sql`), to implement the fix.
- 06Re-run only the affected `pgTAP` tests via `atlas bash` to quickly verify your SQL changes. Example: `atlas bash "pg_prove -v t/orders_tests.sql"`.
- 07Review the unified diff presented by Atlas for your SQL file changes and approve them before writing to disk.
- 08Once the SQL fix is verified and committed, mark the corresponding `todowrite` entry as complete.
