How do I control the order files are loaded in karma config - angularjs

Question

I'm testing an Angular app with Karma. I've got everything working, but it seems like I'm doing something wrong.
https://gist.github.com/guyjacks/7bca850844deb612e681
Karma will throw the following error if I comment out 'app/notes/notes.main.js' :
Uncaught Error: [$injector:nomod] Module 'notes.main' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

I don't want to have to manually list each application file to control the order in which each file loads. Am I don't something wrong or do I just have to list each file in the order I want?
---- Solution based on the accepted answer ----
My app is organized into modules as recommended by the Angular Style Guide: https://github.com/johnpapa/angular-styleguide.
'app/app.module.js',
'app/**/*.module.js',
'app/**/*.service.js',
'app/**/*.controller.js',
'app/**/*.directive.js',
'app/**/*.js'
I don't think the following lines are necessary above
'app/**/*.service.js',
'app/**/*.controller.js',
'app/**/*.directive.js'
when each module has an angular module declared in the *.module.js file like my app does.
That said, if you did need to explicitly load services before controllers & controllers before directives then this would be the way to do it.

Update : I could not see your karma file, now Gist link is fixed.
The point in notes[.]main.js is causing the problem,
So, 'app/**/*.js' is not matching notes.main.js.
Try now like this : app/**/*. *.js
=============================================================
Before update :
You have to load the modules that you app depends on, in karma config. file :
module.exports = function(config) {
config.set({
.......
// list of files / patterns to load in the browser
files: [
'./client/app/vendors/angular/angular.js',
// =====> load Your modules here ...
'./client/app/app.js',
'./client/app/controllers/*.js',
'./client/app/directives/*.js',
'./client/app/services/*.js',
'./test/client/unit/**/*.js'
],
.....
}) }
