如何配置Karma以与requirejs和qunit一起使用

Question

I'm trying to piece karma and requirejs together. but find a big issue cannot find any answer. I have a project using requirejs and I'm using qunit as its testing framework. they work fine before karma comes in. After following the Karma requirejs instruction , I got an error and could not find the proper solution. The karma version is 0.12.6

The error is:

Uncaught Error: Mismatched anonymous define () module ....

How can I let them work together?

here is my files structure

projectroot
    |
    |----\src
    |    |
    |    |----\demo
    |    |    |
    |    |    |----hello.js
    |    |
    |    |----\test
    |         |
    |         |----hello_test.js
    |         |----test_main.js      
    |       
    |----karma.conf.js    

my karma.conf.js

// Karma configuration

module.exports = function(config) {
  config.set({

    singleRun: false
  });
};

my test-main.js

var allTestFiles = [];
var TEST_REGEXP = /(spec|test)\.js$/i;

var pathToModule = function(path) {
  return path.replace(/^\/base\//, '').replace(/\.js$/, '');
};

Object.keys(window.__karma__.files).forEach(function(file) {
  if (TEST_REGEXP.test(file)) {
    // Normalize paths to RequireJS module names.
    allTestFiles.push(pathToModule(file));
  }
});

console.log(allTestFiles);
require.config({
  // Karma serves files under /base, which is the basePath from your config file
  baseUrl: '/base',

  // dynamically load all test files
  deps: allTestFiles,

  // we have to kickoff jasmine, as it is asynchronous
  callback: window.__karma__.start
});

my hello_test.js

define(function(){
  it("is a simple test", function(){
    ok(true, "hope it works");
    });
});

Thank you!

ADD the final error report screen:

You can see my hello_test.js is loaded. I read the docs about #mismatch at requirejs.org. It looks like requirejs cannot handle the module name when it's not loaded through their conventional way.

Answer 1

My Mistake

two mistakes in my files:

1. misspell the included in karma.conf.js
2. in qunit test file.

correct qunit test case should be

define(function(){
    test("is a simple test", function(){
        ok(true, "hope it works");
    });
});

NOT it("is a simple test", function() ...

Answer 2

Not sure if with your two changes you got it to work or not, but after spending about six hours fighting this same problem, I'd suggest either:

• Removing your line {pattern: 'src/demo/*.js', included: false},
• or, adding 'src/demo/hello.js' to your exclude: [ ] array.

This was part of what caused many of my headaches.
