Exploit Me: TestCase Bypass IV

---

Task

Now I have merged TestCase Bypass with UserCodeCheck Bypass. This task is similar to the UserCodeCheck Bypass II but the overall protection has been, again, increased. Since some code check bypass methods have been prevented. You need to bypass the TestCases instead.

You have to write a mul(a,b) function receiving a and b as integer, and it should return a result of a * b.

There are tests as follow:

• Enhanced Anti-Cheat detection in the Preloaded
• Code length check in the TestCases
• 100 randomized tests in the TestCases

Same as always, pass this kata. =]

Preloaded

const fs = module.require('fs');
const usercode = fs.readFileSync('/home/codewarrior/solution.txt', 'utf8');
const limit = 0;

ACTest();

---

TestCases

global.describe(`<${limit} characters`, function(){
  Test.assertDeepEquals(usercode.length < limit, true, `Unfortunately, it was tooooooo long!! :'(\nLimitation: <${limit}\nYour code: ${usercode.length}\n`);
});

global.describe('Example Test Case', function(){
  Test.assertDeepEquals(mul(2,4), 8, 'NO!!!');
});

Note: The purpose of Exploit Me kata series is to study about vulnerabilities in CodeWar test system, in order to prevent them as much as possible in authoring prospective katas. Using this knowledge exploiting other katas to pass them illegally is not recommended. =]
