How specify test-files with .mocharc config file

Question

I currently run mocha tests with npm scripts like

mocha test/mocha.js test/crc/mocha.js test/multibyte/test.js

I added additional three test files and I start to wonder maybe use configuration file like .mocharc.js, and call simply mocha, but what ever I try mocha always runs all .js files in "test" folder.

• I started with this tutorial where they use file property, but it wont work.
• Some SO answer points me to mocha example on github where they use watch-files property but it still wont work.
• I tried use absolute path, relative path
• according to mocha official documentation I should use file property, but it wont work

All this is so confusing and I cant find any config file documentation, more than what file names should I use.

Does anyone knows how I can run just these three test-files with config file ?

I know I can use npm script like before, but maybe there is way ?

Answer 1

You can use spec:

.mocharc.json:

{
    "spec": "./test/**/*.js"    
}
