Desired behavior:

From the documentation:

A String or Array of glob patterns used to ignore test files that would otherwise be shown in your list of tests. Cypress uses minimatch with the options: {dot: true, matchBase: true}. We suggest using http://globtester.com to test what files would match.

ignoreTestFiles should accept an array of strings that are glob patterns and not return an error.

Steps to reproduce: (app code and test code)

1. Create an environment file
2. Add the following code to the environment file:

{
  "ignoreTestFiles": [
    "**/folder1/someTest.spec.js",
    "**/folder2/subfolder2/someOtherTest.spec.js"
  ]
}

3. Run Cypress with the newly created environment file
