In my npm package, I would like to emulate the pattern Meteor follows: a source file (named client.js) has a test file (named client.tests.js) live in a src/ folder. Tests run with the npm test command.

I'm following the usage docs to the 't'. I do not want to use a find in my package test command.

1. I understand that mocha can recursively execute tests:

   
   
   

   mocha --recursive




2. I understand that mocha can execute tests in a specific subfolder using the --recursive flag:

   
   
   

   mocha src --recursive




3. I also understand that I can specify a glob to filter files by passing *.tests.js:

   
   
   

   mocha *.tests.js

But, I want all three. I want mocha to test only files ending in tests.js in the src folder, recursively checking subdirectories.

mocha --recursive *.tests.js



// See the files?

$ > ll ./src/app/

total 168

-rw-r--r--  ... client.js

-rw-r--r--  ... client.tests.js



// Option A

$ > mocha --recursive *.tests.js

Warning: Could not find any test files matching pattern: *.tests.js

No test files found



// Option B

$ > mocha *.tests.js --recursive

Warning: Could not find any test files matching pattern: *.tests.js

No test files found.



// Option C

$ > mocha --recursive src/app/*.tests.js

3 passing (130ms)

3 failing

So...

1. Why is mocha not picking up the *.tests.js files in the subfolders?


2. Why DOES it work if I specify the full path to the file?


3. How do I make it work as desired?
