Source maps ignored and incorrect line shown when using nyc

[jonsadka]

Hi there,

First off, thank you for your work on this 😄. I have everything seemingly working butI keep seeing errors pointing to the first line of the built file. For example, notice how the error points to the use strict of line 1.

I look at all the tickets and the closest was #19. I feel like I have something misconfigured but still stuck and hope someone can help. Thanks!

// test/utils/order.ts
import test from 'ava';

import {formatOrderDate} from '../../src/utils/order';
test('formatOrderDate > pretty prints the date', (t) => {
  t.is(formatOrderDate(1586130298135), 'April 5, 2220');
});

// build-temp/tests/utils/order.js
"use strict";
var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
const ava_1 = __importDefault(require("ava"));
const order_1 = require("../../src/utils/order");
ava_1.default('formatOrderDate > pretty prints the date', (t) => {
    t.is(order_1.formatOrderDate(1586130298135), 'April 5, 2220');

Could you try by following the instructions in #20?

I do think we should try and handle source maps better in AVA itself. Stack trace handling is being refactored at the moment and that should land before we can tackle this, but will follow-up.

(I'm closing this issue for housekeeping purposes, but let's keep the conversation going.)

To document incase others are having the same issue, this is related to nyc which others have reported istanbuljs/nyc#619. Removing nyc got source maps working
