TypeError: modules[moduleId] is undefined

Question

I am trying to run jasmine unit testing with Jenkins using Firefox browser on Linux and I keep having this behavior:

[32m02 08 2017 08:16:26.443:INFO [Firefox 50.0.0 (Windows 8.1 0.0.0)]:  [39mConnected on socket /#KYlvgi9JYtXnD1jZAAAB with id manual-931

Firefox 50.0.0 (Windows 8.1 0.0.0) ERROR

Firefox 50.0.0 (Windows 8.1 0.0.0) ERROR

The exception is on this Line of code:

// Execute the module function
/******/        modules[moduleId].call(module.exports, module, module.exports, __webpack_require__);

I research a lot about the issue, but I couldn't find any solution. Is there anyone that can help me to solve it.

Answer 1

I faced same issue and found that in Karma.conf.js, I was using wrong configuration for "files" as

module.exports = function (config) {
config.set({
    basePath: '.',
    frameworks: ['jasmine'],
    files: [
        '../../ClientApp/dist/vendor.js',
        './boot-tests.ts'
    ],

Modified this to target only files which contain unit tests as

module.exports = function (config) {
config.set({
    basePath: '.',
    frameworks: ['jasmine'],
    files: [
        '../../ClientApp/**/*.spec.ts'
    ],

and now I don't get this error. Though something else going wrong in my tests so getting other errors but seems this specific issue resolved.
