toHaveTextResource()

Checks that a resource result contains text content matching the expected string exactly.

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

Usage​

const result = await app.readResource('file:///app/test.txt');
await expect(result).toHaveTextResource('Hello world');

Parameters​

  • expectedText (string): The exact text content to match

Example​

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

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

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

  // Check exact text match
  await expect(result).toHaveTextResource('{"key": "value"}');

  await app.close();
});
