How to specify test directory for mocha?

Question

Mocha tries to find test files under test by default, how do I specify another dir, e.g. server-test?

Answer 1

If in node.js, some new configurations as of Mocha v6:

Option 1: Create .mocharc.json in project's root directory:

{
  "spec": "path/to/test/files"
}

Option 2: add mocha property in project's package.json:

{
  ...

  "mocha": {
    "spec": "path/to/test/files"
  }
}
