Implementation Reference

  • The handler function that makes an authenticated GET request to the LoadRunner Cloud API to retrieve scripts for the specified load test in the project.
    const executeFunction = async ({ projectId, loadTestId }) => {
      const baseUrl = process.env.LRC_BASE_URL;
      const tenantId = process.env.LRC_TENANT_ID;
      const token = await getAuthToken();
      try {
        // Construct the URL with query parameters
        const url = new URL(`${baseUrl}/projects/${projectId}/load-tests/${loadTestId}/scripts`);
        url.searchParams.append('TENANTID', tenantId);
    
        // Set up headers for the request
        const headers = {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${token}`
        };
    
        // Perform the fetch request
        const response = await fetch(url.toString(), {
          method: 'GET',
          headers
        });
    
        // Check if the response was successful
        if (!response.ok) {
          const text = await response.text();
          try {
            const errorData = JSON.parse(text);
            throw new Error(JSON.stringify(errorData));
          } catch (jsonErr) {
            // Not JSON, log the raw text
            console.error('Non-JSON error response:', text);
            throw new Error(text);
          }
        }
    
        // Parse and return the response data
        const text = await response.text();
        try {
          const data = JSON.parse(text);
          return data;
        } catch (jsonErr) {
          // Not JSON, log the raw text
          console.error('Non-JSON success response:', text);
          return { error: 'Received non-JSON response from API', raw: text };
        }
      } catch (error) {
        console.error('Error retrieving load test scripts:', error);
        return { error: 'An error occurred while retrieving load test scripts.' };
      }
    };
  • The tool schema defining the name, description, and input parameters (projectId and loadTestId as required strings).
    function: {
      name: 'projects_getLoadTestScripts',
      description: 'Retrieve scripts for a load test in a project from LoadRunner Cloud.',
      parameters: {
        type: 'object',
        properties: {
          projectId: {
            type: 'string',
            description: 'The ID of the project.'
          },
          loadTestId: {
            type: 'string',
            description: 'The ID of the load test.'
          }
        },
        required: ['projectId', 'loadTestId']
      }
    }
  • tools/paths.js:1-11 (registration)
    The toolPaths array includes the path to this tool's definition file, enabling its dynamic discovery and registration.
    export const toolPaths = [
      'loadrunner-cloud/load-runner-cloud-api/projects-get-projects.js',
      'loadrunner-cloud/load-runner-cloud-api/test-runs-get-active-test-runs.js',
      'loadrunner-cloud/load-runner-cloud-api/test-runs-get-test-run-transactions.js',
      'loadrunner-cloud/load-runner-cloud-api/test-runs-get-test-run-summary.js',
      'loadrunner-cloud/load-runner-cloud-api/test-runs-get-http-responses.js',
      'loadrunner-cloud/load-runner-cloud-api/test-runs-get-test-run-recent.js',
      'loadrunner-cloud/load-runner-cloud-api/projects-get-load-tests.js',
      'loadrunner-cloud/load-runner-cloud-api/projects-get-load-test-scripts.js',
      'loadrunner-cloud/load-runner-cloud-api/projects-get-load-test-runs.js'
    ];
  • lib/tools.js:7-16 (registration)
    The discoverTools function dynamically imports the apiTool object from each file in toolPaths, registering all tools including projects_getLoadTestScripts.
    export async function discoverTools() {
      const toolPromises = toolPaths.map(async (file) => {
        const module = await import(`../tools/${file}`);
        return {
          ...module.apiTool,
          path: file,
        };
      });
      return Promise.all(toolPromises);
    }
  • Uses getAuthToken helper (imported from auth-get-token.js) to obtain authentication token for API requests.
    const executeFunction = async ({ projectId, loadTestId }) => {
      const baseUrl = process.env.LRC_BASE_URL;
      const tenantId = process.env.LRC_TENANT_ID;
      const token = await getAuthToken();
      try {
        // Construct the URL with query parameters
        const url = new URL(`${baseUrl}/projects/${projectId}/load-tests/${loadTestId}/scripts`);
        url.searchParams.append('TENANTID', tenantId);
    
        // Set up headers for the request
        const headers = {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${token}`
        };
    
        // Perform the fetch request
        const response = await fetch(url.toString(), {
          method: 'GET',
          headers
        });
    
        // Check if the response was successful
        if (!response.ok) {
          const text = await response.text();
          try {
            const errorData = JSON.parse(text);
            throw new Error(JSON.stringify(errorData));
          } catch (jsonErr) {
            // Not JSON, log the raw text
            console.error('Non-JSON error response:', text);
            throw new Error(text);
          }
        }
    
        // Parse and return the response data
        const text = await response.text();
        try {
          const data = JSON.parse(text);
          return data;
        } catch (jsonErr) {
          // Not JSON, log the raw text
          console.error('Non-JSON success response:', text);
          return { error: 'Received non-JSON response from API', raw: text };
        }
