Implementation Reference

• tools/loadrunner-cloud/load-runner-cloud-api/projects-get-load-test-scripts.js:11-59 (handler)

  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.' };
    }
  };

• tools/loadrunner-cloud/load-runner-cloud-api/projects-get-load-test-scripts.js:69-86 (schema)

  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);
  }

• tools/loadrunner-cloud/load-runner-cloud-api/projects-get-load-test-scripts.js:11-54 (helper)

  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 };
      }
