How to create a custom stack trace?

[gajus]

I am assuming Sentry to monitor our tests.

My tests fail with a custom error object that describes message and location of the error, e.g.

{
  message: 'Something failed',
  file: '/Users/gajus/Documents/dev/contra/contra-web-app/tests/e2e/foo.spec.ts',
  line: 6,
  column: 42
},

I can capture this event with captureException(new Error(myError.message)) However, that will not have the relevant stack trace.

Is there a utility that would help me to generate Sentry compatible stack frame based on this information?

Effectively, given file, line and column, I need something like:

{
  filename: '/Users/gajus/Documents/dev/contra/contra-web-app/node_modules/@playwright/test/lib/worker.js',
  module: '@playwright.test.lib:worker',
  function: 'process.<anonymous>',
  lineno: 88,
  colno: 5,
  in_app: false,
  pre_context: [
    "  if (message.method === 'stop') {",
    '    await gracefullyCloseAndExit();',
    '    return;',
    '  }',
    '',
    "  if (message.method === 'run') {",
    '    const runPayload = message.params;'
  ],
  context_line: '    await workerRunner.runTestGroup(runPayload);',
  post_context: [
    '  }',
    '});',
    '',
    'async function gracefullyCloseAndExit() {',
    '  if (closed) return;',
    '  closed = true; // Force exit after 30 seconds.',
    ''
  ]
},

Found addContextToFrame 🥳

How did you end up using this? Are you mutating the event in an event processor?

I am issuing a custom event using captureEvent.
