How to use the @truffle/expect.one function in @truffle/expect

install: async function(options, callback) {
    expect.options(options, ["working_directory", "ethpm"]);

    expect.options(options.ethpm, ["registry", "ipfs_host"]);

    expect.one(options.ethpm, ["provider", "install_provider_uri"]);

    // ipfs_port and ipfs_protocol are optinal.

    const provider =
      options.ethpm.provider ||
      new Web3.providers.HttpProvider(options.ethpm.install_provider_uri, {
        keepAlive: false
      });
    let host = options.ethpm.ipfs_host;

    if (host instanceof EthPM.hosts.IPFS === false) {
      host = new EthPM.hosts.IPFSWithLocalReader(
        options.ethpm.ipfs_host,
        options.ethpm.ipfs_port,
        options.ethpm.ipfs_protocol
      );

function prepareConfig(options) {
  expect.options(options, ["contracts_build_directory"]);

  expect.one(options, ["contracts_directory", "files"]);

  // Use a config object to ensure we get the default sources.
  const config = Config.default().merge(options);

  config.compilersInfo = {};

  if (!config.resolver) config.resolver = new Resolver(config);

  if (!config.artifactor) {
    config.artifactor = new Artifactor(config.contracts_build_directory);
  }

  return config;
}
