chore(functional): add tests for supported fips endpoints

[trivikr]

Issue

Internal JS-2904

Description

Adds tests for supported FIPS endpoints

Code used for populating test cases

// The models directory contains smithy models in *.json format
// The endpoints.json contains RIP endpoints

import { readFile, readdir, writeFile } from "fs/promises";

const findVal = (object, key) => {
  let value;
  Object.keys(object).some((k) => {
    if (k === key) {
      value = object[k];
      return true;
    }
    if (object[k] && typeof object[k] === "object") {
      value = findVal(object[k], key);
      return value !== undefined;
    }
  });
  return value;
};

const getServiceInfo = (api) => {
  return findVal(api, "aws.api#service");
};

const endpointPrefixSdkIdHash = {};
const models = await readdir("models");
for (const modelFileName of models) {
  const model = JSON.parse(
    (await readFile(`models/${modelFileName}`)).toString()
  );
  const serviceInfo = getServiceInfo(model);
  endpointPrefixSdkIdHash[
    serviceInfo.endpointPrefix === "api.tunneling.iot"
      ? "iotsecuredtunneling"
      : serviceInfo.endpointPrefix
  ] = serviceInfo.sdkId;
}

const isFipsRegion = (region) =>
  region.startsWith("fips-") || region.endsWith("-fips");

const testCases = [];
const endpoints = JSON.parse((await readFile("endpoints.json")).toString());
for (const partition of endpoints.partitions) {
  for (const [endpointPrefix, serviceConfig] of Object.entries(
    partition.services
  )) {
    for (const [region, regionConfig] of Object.entries(
      serviceConfig.endpoints
    )) {
      if (isFipsRegion(region)) {
        const { hostname } = regionConfig;
        const regionRegex = partition.regionRegex
          .replace("\\\\", "\\")
          .replace(/^\^/g, "")
          .replace(/\$$/g, "");
        const signingRegion =
          regionConfig.credentialScope?.region ||
          hostname.match(regionRegex)[0];
        testCases.push({
          endpointPrefix,
          sdkId: endpointPrefixSdkIdHash[endpointPrefix],
          region,
          signingRegion,
          hostname,
        });
      }
    }
  }
}
await writeFile("testCases.json", JSON.stringify(testCases, null, 2));
