The setup() function is called before each test, and can be used to perform any setup required for the test. We can use the setup() function to automatically import the transform-stream.js file into the test.js file, and make the TransformStreamDefaultController object available in the test.js file. To do this, we can add the following line to the top of the test.js file:13import { setup } from "./resources/testharness.js";14setup(() => {15  import "resources/transform-stream.js";16});17The above test will now pass. However, it would be better if we could use the setup() function to import the transform-stream.js file only if the test requires it. To do this, we can use the testharness.js promise_test() function. The promise_test() function is a variant of the test() function, which allows the test to return a Promise
