ZATU

USAGE: You would need to define your function and test cases object before calling the test function, as in your original prompt.

Example structure to run this utility:

import { assertEqual } from "zatu";
function isPrimeNumber(input) { 
  // Function implementation goes here
  const n = Number(input);

  if (!Number.isInteger(n) || n <= 1) return false;
  if (n === 2) return true;
  // ... rest of the logic
  return true; 
} 

const examplePrimeNumbers = { 
  "0": false, 
  "1": false, 
  "2": true, 
  "4": false, 
  "7": true,
  // ... rest of the test cases
}; // Your test cases

assertEqual(isPrimeNumber, examplePrimeNumbers);

Dynamic Import

const importPkg = async url => await import(`data:text/javascript,${encodeURIComponent(await (await fetch(url)).text())}`);
const z = await importPkg("https://unpkg.com/zatu@latest/assertEqual");
z.assertEqual(isPrimeNumber, examplePrimeNumbers);

Example Test Cases

z.assertEqual(fn, {
  // Single value functions
  "1": 1,
  "5": 120,

  // Boolean / primitive outputs
  "1": false,
  "2": true,

  // Array input (single param)
  "[1,2,3]": false,
  "[1,1,2]": true,

  // Tuple input (spread into multiple params)
  '["anagram","nagaram"]': true,
  '["rat","car"]': false,

  // Objects
  '{"name":"rahul","age":30}': true,

  // Strings
  '"hello"': 5,
  '"abc"': 3,

  // Mixed
  "10": true,
  "[1,2,3]": false,
  '["a","b"]': true,
  '{"x":1}': false,
  "0": false,

  // Nested arrays
  '["eat","tea","tan","ate","nat","bat"]': [["eat","tea","ate"],["tan","nat"],["bat"]],
  '["abc","bca","cab","bac","acb"]': [["abc","bca","cab","bac","acb"]],
  '[]': []
});
