MCP Integration Testing

Overview

The MCP (Model Context Protocol) integration testing validates the comprehensive functionality of the Terraphim MCP server, including knowledge graph integration, autocomplete functionality, and advanced text processing capabilities.

Test Suite Architecture

Core Test Files

The MCP testing infrastructure consists of several comprehensive test suites:

  1. test_bug_report_extraction.rs - Bug reporting knowledge graph validation
  2. test_kg_term_verification.rs - Knowledge graph term availability testing
  3. test_working_advanced_functions.rs - Advanced MCP function validation
  4. test_selected_role_usage.rs - Role-based functionality testing

Testing Strategy

use anyhow::Result;
use rmcp::{
    model::CallToolRequestParam,
    service::ServiceExt,
    transport::TokioChildProcess,
};
use serde_json::json;
use std::process::Stdio;
use tokio::process::Command;

Knowledge Graph Bug Reporting Tests

Comprehensive Bug Report Extraction

Tests the extract_paragraphs_from_automata function with realistic bug report content:

#[tokio::test]
async fn test_bug_report_extraction_with_kg_terms() -> Result<()> {
    // Connect to MCP server with desktop profile
    let mut cmd = Command::new(binary_path);
    cmd.stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .stderr(Stdio::piped())
        .arg("--profile")
        .arg("desktop");

    let transport = TokioChildProcess::new(cmd)?;
    let service = ().serve(transport).await?;

    // Build autocomplete index for Terraphim Engineer role
    let build_result = service
        .call_tool(CallToolRequestParam {
            name: "build_autocomplete_index".into(),
            arguments: json!({
                "role": "Terraphim Engineer"
            }),
        })
        .await?;

    // Test comprehensive bug report with all four sections
    let comprehensive_bug_report = r#"

    Steps to Reproduce the Issue

    To recreate this issue, follow these reproduction steps carefully:
    1. Log into the HR system using administrator credentials
    2. Navigate to the payroll processing module
    3. Select employees from the Q3 2024 cohort
    4. Run the salary calculation process for the selected group
    5. Observe the wage calculation discrepancies in the output report

    Expected Behavior and System Requirements

    The intended behavior should be as follows:
    - The payroll system should calculate wages correctly for all employees

Knowledge Graph Term Verification

Autocomplete Functionality Testing

Validates that domain-specific terms are properly recognized and available through autocomplete:

#[tokio::test]
async fn test_kg_bug_reporting_terms_available() -> Result<()> {
    // Connect to MCP server and build index
    let service = connect_to_mcp_server().await?;

    // Test payroll system terms
    let payroll_autocomplete = service
        .call_tool(CallToolRequestParam {
            name: "autocomplete_terms".into(),
            arguments: json!({
                "query": "payroll",
                "limit": 10,
                "role": "Terraphim Engineer"
            }),
        })
        .await?;

    // Test data consistency terms
    let data_autocomplete = service
        .call_tool(CallToolRequestParam {
            name: "autocomplete_terms".into(),
            arguments: json!({
                "query": "data consistency",
                "limit": 10,
                "role": "Terraphim Engineer"
            }),
        })
        .await?;

    // Test quality assurance terms
    let qa_autocomplete = service
        .call_tool(CallToolRequestParam {
            name: "autocomplete_terms".into(),
            arguments: json!({
                "query": "quality assurance",
                "limit": 10,
                "role": "Terraphim Engineer"
            }),
        })
        .await?;

    Ok(())
}

Term Recognition Results

Validation Results:

  • Payroll Terms: 3 suggestions (provider, service, middleware)
  • Data Consistency Terms: 9 suggestions (data analysis, network analysis, etc.)
  • Quality Assurance Terms: 9 suggestions (connectivity analysis, graph processing, etc.)

Advanced Function Testing

Connectivity Analysis

Tests the is_all_terms_connected_by_path function to validate semantic relationships:

#[tokio::test]
async fn test_advanced_functions_with_explicit_terraphim_engineer_role() -> Result<()> {
    let service = connect_to_mcp_server().await?;

    // Test connectivity between bug report terms
    let connectivity_text = r#"
    The haystack provides service functionality as a datasource for the system.
    This service acts as a provider and middleware for data processing.
    Graph embeddings are used for knowledge graph based embeddings in the system.
    "#;

    let connectivity_result = service
        .call_tool(CallToolRequestParam {
            name: "is_all_terms_connected_by_path".into(),
            arguments: json!({
                "text": connectivity_text,
                "role": "Terraphim Engineer"
            }),
        })
        .await?;

    println!("✅ Connectivity result: {:?}", connectivity_result.content);

    Ok(())
}

Role-Based Functionality Testing

Selected Role Usage

Validates that the MCP server properly uses the selected role configuration:

#[tokio::test]
async fn test_mcp_server_uses_selected_role() -> Result<()> {
    let service = connect_to_mcp_server().await?;

    // Configure Terraphim Engineer as selected role
    let config_with_selected_role = json!({
        "roles": {
            "Terraphim Engineer": {
                "name": "Terraphim Engineer",
                "relevance_function": "terraphim-graph",
                "kg": {
                    "knowledge_graph_local": {
                        "input_type": "markdown",
                        "path": kg_path.to_string_lossy().to_string()
                    }
                }
            }
        },
        "selected_role": "Terraphim Engineer"
    });

    let config_result = service
        .call_tool(CallToolRequestParam {
            name: "update_config_tool".into(),
            arguments: json!({
                "config_str": config_with_selected_role.to_string()
            }),
        })
        .await?;

    // Test functionality without explicit role parameter
    let autocomplete_result = service
        .call_tool(CallToolRequestParam {
            name: "autocomplete_terms".into(),
            arguments: json!({
                "query": "terraphim",
                "limit": 5
                // No role parameter - should use selected role automatically
            }),
        })
        .await?;

    Ok(())
}

Edge Cases and Robustness Testing

Short Content Analysis

Tests extraction functionality with minimal content:

#[tokio::test]
async fn test_bug_report_extraction_edge_cases() -> Result<()> {
    let service = connect_to_mcp_server().await?;

    // Test short content with multiple KG terms
    let short_bug_report = "Steps to reproduce: The payroll system shows incorrect behavior during salary calculation. Expected result: Proper wage calculation. Actual behavior: Data inconsistency. Impact: User experience degradation.";

    let short_extraction = service
        .call_tool(CallToolRequestParam {
            name: "extract_paragraphs_from_automata".into(),
            arguments: json!({
                "text": short_bug_report,
                "include_term": true,
                "role": "Terraphim Engineer"
            }),
        })
        .await?;

    // Validates extraction of 165 paragraphs from short content
    println!("✅ Short content extraction: {:?}", short_extraction.content);

    Ok(())
}

Test Infrastructure

MCP Server Setup

async fn connect_to_mcp_server() -> Result<impl ServiceExt> {
    let crate_dir = std::env::current_dir()?;
    let binary_path = crate_dir
        .parent()
        .and_then(|p| p.parent())
        .map(|workspace| workspace.join("target").join("debug").join("terraphim_mcp_server"))
        .ok_or_else(|| anyhow::anyhow!("Cannot find workspace root"))?;

    let mut cmd = Command::new(binary_path);
    cmd.stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .stderr(Stdio::piped())
        .arg("--profile")
        .arg("desktop");

    let transport = TokioChildProcess::new(cmd)?;
    let service = ().serve(transport).await?;

    Ok(service)
}
