Hey, @nopeless! I'm here to help you with bugs, answer questions, and guide you toward becoming a contributor. While you're waiting for a human maintainer, I'm available to assist you.

The issue with ctx.nuxt not existing when build: false is likely due to the context not being properly initialized in the startServer function. To resolve this, ensure ctx.nuxt is initialized before it is accessed. Here is a potential fix:

1. Ensure ctx.nuxt is initialized in the useTestContext function or before it is used in the startServer function.
2. Add a check to ensure ctx.nuxt is defined before accessing its properties.

Here is a modified version of the startServer function with added checks:

export async function startServer(options: StartServerOptions = {}) {
  const ctx = useTestContext();
  await stopServer();
  const host = '127.0.0.1';
  const port = ctx.options.port || await getRandomPort(host);
  ctx.url = `http://${host}:${port}/`;

  if (!ctx.nuxt) {
    throw new Error('ctx.nuxt is not defined. Ensure that the context is properly initialized.');
  }

  if (ctx.options.dev) {
    const nuxiCLI = await kit.resolvePath('nuxi/cli');
    ctx.serverProcess = execa(nuxiCLI, ['_dev'], {
      cwd: ctx.nuxt.options.rootDir,
      stdio: 'inherit',
      env: {
        ...process.env,
        _PORT: String(port), // Used by internal _dev command
        PORT: String(port),
        HOST: host,
        NODE_ENV: 'development',
        ...options.env,
        ...ctx.options.env,
      },
    });
    await waitForPort(port, { retries: 32, host }).catch(() => {});
    let lastError;
    for (let i = 0; i < 150; i++) {
      await new Promise(resolve => setTimeout(resolve, 100));
      try {
        const res = await $fetch<string>(ctx.nuxt.options.app.baseURL, { responseType: 'text' });
        if (!res.includes('__NUXT_LOADING__')) {
          return;
        }
      } catch (e) {
        lastError = e;
      }
    }
    ctx.serverProcess.kill();
    throw lastError || new Error('Timeout waiting for dev server!');
  } else {
    ctx.serverProcess = execa('node', [
      resolve(ctx.nuxt.options.nitro.output!.dir!, 'server/index.mjs'),
    ], {
      stdio: 'inherit',
      env: {
        ...process.env,
        PORT: String(port),
        HOST: host,
        NODE_ENV: 'test',
        ...options.env,
        ...ctx.options.env,
      },
    });
    await waitForPort(port, { retries: 20, host });
  }
}

This modification ensures ctx.nuxt is checked and an error is thrown if it is not defined, helping to identify the root cause of the issue ^[1].
