Testacular: encountered a declaration exception

I have defined a empty module in angular.js: ``` angular.module('todoList', [], function () { }) ``` then I want test it, in my `conf.js`, I load these javascript: ``` files = [ JASMINE, JASMINE_ADAPTER, // lib '../js/lib/angular.min.js', '../js/lib/jquery-1.9.1.min.js', // our app '../js/project.js', // test file "test/*.js" ]; ``` Then I want test it in test file: ``` describe('My own function', function(){ beforeEach(module('todoList')); }); ``` but this step tell me `FAILED My own function encountered a declaration exception` I don't understand why just a load module sentence would cause wrong How can I fix this problem?
