Test Output Processor

File: src/processors/test_output.py

Priority: 21

Name: test

Handles test runner output across all major ecosystems.

Supported Commands

pytest, python -m pytest, jest, vitest, mocha, cargo test, go test, rspec, phpunit, bun test, npm/yarn/pnpm test, dotnet test, swift test, mix test.

Strategy

• Passing tests: collapsed into [N tests passed]
• Failing tests: full stack trace and error messages preserved
• Long tracebacks: truncated to 30 lines (head + tail with marker) via max_traceback_lines
• Platform/rootdir/plugins lines: removed (pytest)
• Final summary line: always kept
• Test dots (RSpec, mix test): counted as pass/fail

Configuration

Parameter	Default	Description
max_traceback_lines	30	Max traceback lines before truncation

Example

Before (pytest):

======== test session starts ========
platform darwin -- Python 3.12.0
collected 100 items
tests/test_1.py::test_func PASSED
... (97 PASSED lines)
tests/test_db.py::test_migration FAILED
======== FAILURES ========
_____ test_migration _____
    def test_migration():
        db = get_db()
>       db.migrate('v2')
E       MigrationError: column 'email' already exists
======== 1 failed, 97 passed in 12.3s ========

After:

[97 tests passed]
tests/test_db.py::test_migration FAILED
======== FAILURES ========
_____ test_migration _____
    def test_migration():
