Version

1.0.0

Reproduction link

https://jsfiddle.net/chrisvfritz/50wL7mdz/

Steps to reproduce

Open the following HTML in the browser and observe console error message

<html>
  <body>
    Open the console to observe error message
    <script>
      // hide warning message in karma test
      // see https://github.com/vuejs/vue-test-utils/issues/42
      var VueTemplateCompiler = {}
    </script>
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
    <script src="https://unpkg.com/@vue/[email protected]/dist/vue-test-utils.iife.js"></script>
  </body>
</html>

What is expected?

IIFE should load without error

What is actually happening?

This new IIFE fails to load in the browser with "Uncaught ReferenceError: testUtils is not defined at vue-test-utils.iife.js:13932"

Last working IIFE was in 1.0.0-beta.33. Broken by #1518 (Optionally hide deprecation errors) which introduces a new import "testUtils" to packages/shared/utils.js. When this new import gets compiled into node_modules/@vue/test-utils/dist/vue-test-utils.iife.js it changes the IIFE signature from (function (...) {...}({}, Vue, VueTemplateCompiler)); to (function (...) {...}({}, Vue, VueTemplateCompiler, testUtils));.

for the record, I'm working around this issue by adding the following JS before importing the IIFE

window.testUtils = {
  config: {}
}

We most likely do a check against process.env for the deprecation errors. I can look at this in the next day or two, should be a quick fix. Thanks!

I thought we had some tests around the IIFE build. I guess not. I will add some.
