test-patterns

A standard pattern for creating Pyramid web applications in tests using the shared pyramid_app fixture.

In plain words
What is it for?
Use it to test requests, custom settings, routes, views, and other Pyramid application behavior.
Why use it?
It avoids each test inventing its own application setup, making tests more consistent and easier to maintain.

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.

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-patterns 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 2d ago.

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.

Unified Pyramid Fixture Pattern for Tests

🎯 Use the Unified pyramid_app Fixture

ALWAYS use the unified pyramid_app fixture for new tests. This is the single, standardized way to create Pyramid applications in tests.

1. Basic Test Pattern

def test_basic_functionality(pyramid_app):
    """Use pyramid_app directly with defaults."""
    app = pyramid_app()
    
    response = app.post_json('/mcp', {
        'jsonrpc': '2.0',
        'id': 1,
        'method': 'tools/list'
    })
    assert response.status_code == 200

2. Test with Custom Settings

def test_custom_settings(pyramid_app):
    """Configure custom settings for your test."""
    settings = {
        "mcp.server_name": "custom-test-server",
        "mcp.mount_path": "/api/mcp"
    }
    app = pyramid_app(settings=settings)
    
    # Test with custom configuration
    response = app.post_json('/api/mcp', {...})
    assert response.status_code == 200

3. Test with Specific Views

def test_with_views(pyramid_app):
    """Add specific views for testing."""
    
    def my_test_view(request):
        return {"message": "test"}
    
    views = [
        (my_test_view, "test_route", {"renderer": "json"})
    ]
    app = pyramid_app(views=views)
    
    # Test the added view
    response = app.get('/test_route') 
    assert response.json == {"message": "test"}

4. Test with Limited Scanning

def test_scoped_tools(pyramid_app):
    """Limit tool scanning to specific module."""
    app = pyramid_app(scan_path="tests.unit.specific_module")
    
    # Only tools from specific_module will be available
    response = app.post_json('/mcp', {
        'jsonrpc': '2.0',
        'id': 1, 
        'method': 'tools/list'
    })
    # Verify only expected tools are listed

5. Test with Ignore Patterns

def test_ignore_problematic_modules(pyramid_app):
    """Ignore specific modules during scanning."""
    app = pyramid_app(ignore=["tests.cornice", "tests.integration.slow"])
    
    # Tools from ignored modules won't be available
    response = app.post_json('/mcp', {
        'jsonrpc': '2.0',
        'id': 1,
        'method': 'tools/list'
    })

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-patterns is a cursor rule published in the GitHub repository cartaorobbin/pyramid-mcp (3 stars, last pushed 10mo ago), licensed MIT. It adds 1,211 tokens to every session, about $0.0061 per session on Opus 5. 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.
