# Browser Type Tester

too heavy to use it in production, but it's good for testing types in browser

## Usage

```ts

import { TypeTester } from "browser-type-tester";

const code = `

  type Speed = "slow" | "medium" | "fast";

  const speed: Speed[] = ["slow"];

function getSpeed(speed: Speed): number {

  switch (speed) {

    case "slow":

      return 10;

    case "medium":

      return 50;

    case "fast":

      return 200;

  }

}

  `;

const typeTest = new TypeTester({ code });

typeTest.test("getSpeed function should return number", () => {

  typeTest

    .expect("getSpeed")

    .toBeType(`(speed: "slow" | "medium" | "fast") => number`);

});

const results = await typeTest.run();

console.log(results);

```
