Vague version question:
Context:
I'm working on an existent node project that has no tests yet, so I read some and realized to use karma and jasmine.
I read some tutos (including these):
So I'm trying to run my specs with grunt and getting this error:
X encountered a declaration exception ReferenceError: Can't find variable: require in file:///(...)-spec.js (line 2) (1)
The line is something like:
var myHelper = require(...);
But if I use via terminal "node-jasmine test" it works like a charm...
My project structure:
- controllers/
- helpers/
- models/
- node_modules/
- resources/
- test/
- test/spec/
- views/
- app.js
- Gruntfile.js
- package.json
In my spec (inside test/spec/) I use a require('../../helpers/helper.js') and that's ok for node-jasmine, but no with grunt.
node-jasmine test:
.....
Finished in 0.015 seconds 5 tests, 5 assertions, 0 failures, 0 skipped
grunt:
Running "jasmine:pivotal" (jasmine) task Testing jasmine specs via PhantomJS
ReferenceError: Can't find variable: require at app.js:1 Service Helper Tests X encountered a declaration exception ReferenceError: Can't find variable: require in file:///(...)/test/spec/serviceHelper-spec.js (line 2) (1)
