This PR brings assertOps and assertResources sanitizers to Deno.test() API. assertOps checks that test doesn't leak async ops, ie. there are no unresolved promises originating from Deno APIs. Enabled by default, can be disabled using Deno.TestDefinition.disableOpSanitizer. assertResources checks that test doesn't leak resources, ie. all resources used in test are closed. For example; if a file is opened during a test case it must be explicitly closed before test case finishes. It's most useful for asynchronous generators. Enabled by default, can be disabled using Deno.TestDefinition.disableResourceSanitizer. We've used those sanitizers in internal runtime tests and it proved very useful in surfacing incorrect tests which resulted in interference between the tests. All tests have been sanitized. Closes #4208 |

CommonJS Module Loading
createRequire(...) is provided to create a require function for loading CJS
modules.
import { createRequire } from "https://deno.land/std/node/module.ts";
const require_ = createRequire(import.meta.url);
// Loads native module polyfill.
const path = require_("path");
// Loads extensionless module.
const cjsModule = require_("./my_mod");
// Visits node_modules.
const leftPad = require_("left-pad");
