Configuring spec = '<glob>' fails

[jginsburgn]

Prerequisites

• Checked that your issue hasn't already been filed by cross-referencing issues with the faq label
• Checked next-gen ES issues and syntax problems by using the same environment and/or transpiler configuration without Mocha to ensure it isn't just a feature that actually isn't supported in the environment in question or a bug in your code.
• 'Smoke tested' the code to be tested by running it outside the real test suite to get a better sense of whether the problem is in the code under test, your usage of Mocha, or Mocha itself
• Ensured that there is no discrepancy between the locally and globally installed versions of Mocha. You can find them with: node node_modules/.bin/mocha --version(Local) and mocha --version(Global). We recommend that you not install Mocha globally.

Description

Asking Mocha to do the work of globbing spec files fails. This makes working without globstar very hard; some CI tools that we use do not allow turning on globstar on the environment shell.

Steps to Reproduce

git clone https://github.com/jginsburgn/mocha-seed.git
cd mocha-seed
git checkout mocha-globbing-bug
npm install
npm test

With your glob your are trying to execute the tests of concat-map package, incl. of all other packages in the node_modules folder.
Your glob doesn't make sense.

Change your glob to "spec": "./*.js" or put your tests in a test subfolder.

Of course. Thanks so much.
