Javascript Test (mocha) With 'import' Js File

I understand module.export and require mannner: Requiring external js file for mocha testing Although it's pretty usable as long as it's a module, I feel this manner is inconvenien

Solution 1:

I usually include a _test object containing references to all my "private" internal variables and functions and expose it on exports. In your case:

./app.js

varINFINITY = 'infinity';

functionfoo() {
    return'bar';
}

exports._test = {
    INFINITY: INFINITY,
    foo: foo
}

./test/app-test.js

var app = require('../app.js')
/* ... */it('should equal bar', function() {
    expect(app._test.foo()).to.equal('bar');
});
it('should equal infinity', function() {
    expect(app._test.INFINITY).to.equal('infinity');
});
