Karma settings

Add coolie framework to karma.config.js

{
  frameworks: ['jasmine', 'coolie'],
  files: [
		{pattern: 'src/*.js', included: false},
		{pattern: 'test/*.spec.js', included: false},
		'test/test-main.js'
	]
}

Test files

Follow the official demo, write your src code /src/circle.js and /src/square.js. But the spec test files get some different.

The /test/circle.spec.js:

 define(function (require) {
  var circle = require('../src/circle.js');
  describe('circle.js', function () {

      // 圆面积
      it('.getArea', function () {
          // 半径为 1 的圆
          expect(circle.getArea(1)).toEqual(Math.PI);
      });

      // 圆周长
      it('.getCircumference', function () {
          // 半径为 1 的圆
          expect(circle.getCircumference(1)).toEqual(2 * Math.PI);
      });
  });
});

And /test/square.spec.js:

 define(function (require) {
  var square = require('../src/square.js')
  describe('square.js', function () {

      // 方形面积
      it('.getArea', function () {
          // 边长为 1 的正方形
          expect(square.getArea(1, 1)).toEqual(1);
      });

      //// 方形周长
      //it('.getCircumference', function () {
      //    // 边长为 1 的正方形
      //    expect(square.getCircumference(1, 1)).toEqual(4);
      //});
  });

});

Finally the /test/test-main.js looks like:

 (function(__karma__, coolie) {
  var tests = [],
    file;
  for (file in __karma__.files) {
    if (__karma__.files.hasOwnProperty(file)) {
      // just include .spec test files
      if (/\.spec\.js$/i.test(file)) {
        tests.push(file);
      }
    }
  }

  coolie.use(tests);

})(window.__karma__, coolie);
