I am using TS

TSError: ⨯ Unable to compile TypeScript:
test.ts:2:23 - error TS2306: File '/workspace/default/solution.ts' is not a module.

2 import { greet } from "./solution";

Solved. Closing.

Fork and fix waiting for approval.

I'm not familiar with chai so not claiming this is the best fix, but replacing the basic tests with this gets it working

    assert(rgb(0, 0, 0) === "000000", 'expected 0,0,0 to equal 000000');
    assert(rgb(0, 0, -20) === "000000", 'expected 0,0,-20 to equal 000000');
    assert(rgb(300, 255, 255) === "FFFFFF", 'expected 300,255,255 to equal FFFFFF');
    assert(rgb(173, 255, 47) === "ADFF2F", 'expected 173,255,47 to equal ADFF2F');

Error test failed:
expected 'ihGVsgaZUsgSPay pKISbPhpcOTmAXIdpdIay…' to equal 'ihGVsgaZUsgSPay pKISbPhpcOTmAXIdpdIay…'

I check the strings:
console.log("ihGVsgaZUsgSPay pKISbPhpcOTmAXIdpdIay…" == "ihGVsgaZUsgSPay pKISbPhpcOTmAXIdpdIay…") // true;

How can I make the "Random test failed error" to show the complete words?

Same.

WHen I try to Test on Typescript I get an error:

TSError: ⨯ Unable to compile TypeScript:
test.ts:7:5 - error TS2552: Cannot find name 'Test'. Did you mean 'test'?

7 Test.assertEquals(rgb(0, 0, 0), "000000")
