toHaveResourceContent()

Checks that a resource result contains content for a specific URI.

This matcher works with ReadResourceResult instances returned by app.readResource().

Usage​

const result = await app.readResource('file:///app/config.json');
await expect(result).toHaveResourceContent('file:///app/config.json');

Parameters​

  • uri (string): The URI to check for in the resource contents

Example​

import { mcpShell } from 'expect-mcp';
import { test, expect } from 'vitest';

test('validate resource has content for URI', async () => {
  const app = mcpShell('node file-server.js');
  await app.initialize();

  const result = await app.readResource('file:///app/config.json');

  // Check that the resource has content for the URI
  await expect(result).toHaveResourceContent('file:///app/config.json');

  await app.close();
});
