Error Message: "Angular Mocks and Jasmine encountered an issue: 'fn' is not a function, instead got Object"

I'm encountering a problem when it comes to unit testing in Angular using Angular-Mocks, Jasmine, and CoffeeScript.

The issue lies within this code snippet:

'use strict'

describe 'sample suite', ->

    beforeEach inject(($rootScope, $compile) ->
        scope = $rootScope.$new()
    )

    it 'should be true', ->
        expect('foo').toBe('foo')

It triggers an error in Angular

debug.html:37 Error: [ng:areq] Argument 'fn' is not a function, got Object
.

On the other hand, the following code works smoothly:

'use strict'

describe 'sample suite', ->

    beforeEach ->
        sample = 'test'

    it 'should be true', ->
        expect('foo').toBe('foo')

This indicates that the usage of the global inject() angular-mocks method doesn't align properly with the CoffeeScript compiler.

Unfortunately, concluding the beforeEach block with return doesn't resolve the issue.

Any assistance on this matter would be greatly appreciated.

Answer №1

When comparing the two sets of code that are functioning and not functioning, a significant difference becomes apparent.

Within the first block, beforeEach is designed to receive the inject as a parameter. However, in the working version, an anonymous function beforeEach -> is used, resulting in the error message

Error: [ng:areq] Argument 'fn' is not a function, got Object
.

'use strict'

describe 'sample suite', ->

  beforeEach ->
    inject ($rootScope, $compile) ->
      scope = $rootScope.$new()


  it 'should be true', ->
    expect('foo').toBe('foo')
