async tests / Cannot read property Symbol(Symbol.iterator)' of undefined

[dcsan]

Issue description or question

when running simple tests I get the error above.
tests run fine from the command line with Mocha.

I am passing in the data from an async function

describe('load yaml', async function() {

  it('from file', async function() {

    let qo = {
      query: 'where is my pink pooch'
    }
    let item = new Taggable(qo)
    let checkList = await loadTestData()
    let found = await item.findTags(checkList)

Wallaby.js configuration file

module.exports = function () {

  process.env.NODE_ENV = 'test'

  return {
    name: 'NAP',

    files: [
      'classes/**/*.js',
      'models/**/*.js',
      'routes/**/*.js',
      'lib/**/*.js',
      'config/**/*', // also need JSON config settings
      // 'server.js'
    ],

    tests: [
      'test/*.js'
    ],

    env: {
      type: 'node',
      // params: {
      //   env: 'NODE_ENV=devbot'
      // }
    },
    debug: true,
    testFramework: 'mocha'

  }
}

We have created this sample with your code and config: https://github.com/ArtemGovorov/wallaby-1806, and it seems to be working as expected:

Could you please clone the repo to see if it's working for you, and if it is, please provide the bits we are missing to reproduce the issue.

From the error message it looks like the checkItems passed into the findTags is undefined for some reason. Try adding some console.log(checkItems) or Wallaby live comments to track why the value is not passed correctly.

Closing this issue due to lack of activity. Will re-open if more information is provided.

is wallaby more stable now? i gave up on it back then tho it seems like a good idea in theory.

"Stability" issues (especially when things are working in another testing framework) are generally caused by problems with your wallaby configuration. If you want to give Wallaby another try, if you email us, we can provide you with an extended trial license. If do so and you have problems with stability, we'd be happy to take a look at your configuration for you.
