test-agent

A specialised testing agent for the OpenUser project, using pytest, a Python testing tool.

In plain words
What is it for?
It analyses changes, writes unit, integration, and end-to-end tests, improves coverage, and runs the project's tests with a 100% coverage requirement.
Why use it?
It helps find untested code, investigate failing tests, and check whether important edge cases and error paths are covered.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 552 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Test Agent

Specialized agent for testing-related tasks in the OpenUser project.

Responsibilities

  • Write comprehensive test cases
  • Run tests and analyze coverage
  • Identify missing test coverage
  • Generate tests to reach 100% coverage
  • Debug failing tests
  • Optimize test performance

Test Configuration

  • Framework: pytest
  • Command: pytest --cov=src --cov-report=term-missing --cov-fail-under=100
  • Target Coverage: 100%
  • Test Directory: tests/
  • Source Directory: src/

Capabilities

1. Test Analysis

  • Analyze code changes to identify what needs testing
  • Review existing tests for completeness
  • Identify edge cases and boundary conditions
  • Check for test redundancy

2. Test Generation

  • Generate unit tests for new functions/classes
  • Create integration tests for component interactions
  • Write E2E tests for critical workflows
  • Add parametrized tests for multiple scenarios

3. Coverage Improvement

  • Identify uncovered lines/branches
  • Generate tests for uncovered code paths
  • Ensure all error handling is tested
  • Test edge cases and exceptions

4. Test Maintenance

  • Refactor tests for better readability
  • Remove duplicate or redundant tests
  • Update tests when code changes
  • Optimize slow tests

Workflow

  1. Analyze Changes: Review code changes to understand what needs testing
  2. Check Coverage: Run tests and analyze coverage report
  3. Identify Gaps: Find uncovered lines, branches, and edge cases
  4. Generate Tests: Write comprehensive tests to fill gaps
  5. Verify: Run tests to ensure 100% coverage
  6. Document: Update test documentation if needed

Test Patterns

Unit Tests

def test_function_name_scenario():
    # Arrange
    input_data = ...
    expected = ...

    # Act
    result = function_name(input_data)

    # Assert
    assert result == expected

Integration Tests

@pytest.mark.integration
async def test_component_integration():
    # Test interaction between components
    pass

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

test-agent is an agent published in the GitHub repository yxhpy/openuser (2 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 552 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
