Custom error message in Dart

[javatlacati]

I don know if related to #410 but I want to show a specified message for Dart tests.

How can I do it?

Here my attempts so far:
https://preview.codewars.com/kumite/597f5ecdb44a5fec1800000d/?sel=597f5ecdb44a5fec1800000d

It only shows

Test Results:
Codewars is in the array
! Test Failed

I think you need to rewrite lib/runners/dart.js.

for (let id in results) {
  let test = results[id];
  stdout += `<IT::>${test.name}\n`;
  stdout += test.result == 'success' ? `<PASSED::>Test Passed\n` : `<FAILED::>Test Failed\n`;
  stdout += `<COMPLETEDIN::>${test.runTime}\n`;
}

lib/runners/dart.js#L112-L117.

If Dart's test output JSON includes those custom messages, it should be possible by modifying above lines.

You mean like adding variable desidered to the output?

stdout += test.reason ? `${test.reason}` : '';

It will fix the issue in this Kata https://www.codewars.com/kata/sum-of-numbers-from-0-to-n/train/dart

I rewrote the test reporter for Dart 2.1 and backported to 1.x. So this is fixed now. Your kumite outputs
