NodeJS, WebStorm and Jasmine: ReferenceError: describe is not defined when debugging

Question

I'm trying to debug some Jasmine tests that I have written using WebStorm 2016.1.2.

My test code looks like this:

var should = require("should");
var myLib = require("../my-lib");

describe("Scenario", () => {
    it("works as expected", () => {
        myLib.do().should.not.throw()
    });
});

My directory structure looks like this:

│
├───node_modules
│   ├───.bin
│   ├───aws-sdk
│   │   └───<snip>
│   ├───jasmine
│   │   └───<snip>
│   ├───jasmine-core
│   │   └───<snip>
│   ├───karma
│   │   └───<snip>
│   ├───karma-jasmine
│   │   └───<snip>
│   ├───should
│   │   └───<snip>
│   └───sinon
│       └───<snip>
├───spec
│   ├───support
│   │   └───jasmine.json
│   └───my-lib.spec.js
└───my-lib.js

And my NodeJS settings in WebStorm look like this:

To debug I'm just hitting F5 and choosing the my-lib.spec.js file to run. I Then get the following stack trace:

"C:\Program Files (x86)\JetBrains\WebStorm 2016.1.2\bin\runnerw.exe" "C:\Program Files\nodejs\node.exe" --debug-brk=22714 my-lib.spec.js

Process finished with exit code 1

If anyone knows how to make WebStorm recognise that Jasmine is installed globally that'd be great.

EDIT: I've set up a Karma run configuration as suggested by lena with the following configuration:

When I hit F5 to run this, a Chrome browser pops up and is blank (I have the JetBrains plugin for Chrome installed)

Solution 1

You are using Node.js run configuration to run your tests - and Node knows nothing about your test framework. You should be using a test runner (karma, for example - as you have karma installed). Try using karma run configuration. See https://confluence.jetbrains.com/display/WI/Running+JavaScript+tests+with+Karma.

BTW, if you like using Should with karma, try karma-should

Solution 2

Try using jasmine-node module.

It depends on the command send to the js file when you press F5. It needs to be jasmine-node <test files> not node <test files>.

Try doing that in the console/terminal and see if it works. It could be web storm sending the wrong command.

If you haven't got jasmine node installed you can do

npm install jasmine-node -g

jasmine-node hasn't been updated in a long time and doesn't support the latest version of Jasmine.
