Deno runs the whole script instead of the method

I have following test:

import { expect } from "jsr:@std/expect";
import { validateInput } from "./webp.ts";

Deno.test("invalid input", () => {
  const fn = validateInput;
  const result = fn('/root', 55);
  expect(result).toThrow();
});

import { expect } from "jsr:@std/expect";
import { validateInput } from "./webp.ts";

Deno.test("invalid input", () => {
  const fn = validateInput;
  const result = fn('/root', 55);
  expect(result).toThrow();
});

When I run deno test it runs the whole webp.ts script instead of just the validateInput() method.

Can you give more info? What is the content of the webp.ts that is not expected to run?

It starts with:

import { exec } from "node:child_process";
import process from "node:process";

const directoryArg: string = process.argv[2];
const qualityArg: string = process.argv[3];

import { exec } from "node:child_process";
import process from "node:process";

const directoryArg: string = process.argv[2];
const qualityArg: string = process.argv[3];

I expected to run only the validateInput method.

That's not how ES modules work. All file is evaluated when it is imported
