Error message in Angular unit testing using TypeScript: TS2304 - Unable to locate the identifier 'module'

I'm currently facing an issue while writing my first Angular unit test in TypeScript. I keep receiving the error TS2304: Cannot find name 'module'. If anyone has any insights or suggestions on how to resolve this, I would greatly appreciate it.

TS2304: Cannot find name 'module'.

Test Code:

/// <reference path="../typings/karma-jasmine/karma-jasmine.d.ts" />
/// <reference path="../typings/angularjs/angular-mocks.d.ts" />

describe("FooTest", () => {
    beforeEach(module("app"));

});

I am utilizing TSD (TypeScript Definition manager) for managing my TypeScript definitions.

tsd.json

{
  "version": "v4",
  "repo": "borisyankov/DefinitelyTyped",
  "ref": "master",
  "path": "typings",
  "bundle": "typings/tsd.d.ts",
  "installed": {
    "jquery/jquery.d.ts": {
      "commit": "ef32bff4d15782dbbabf99ecb17ba22119cc2bd2"
    },
    "angularjs/angular.d.ts": {
      "commit": "ef32bff4d15782dbbabf99ecb17ba22119cc2bd2"
    },
    "karma-jasmine/karma-jasmine.d.ts": {
      "commit": "ef32bff4d15782dbbabf99ecb17ba22119cc2bd2"
    },
    "jasmine/jasmine.d.ts": {
      "commit": "ef32bff4d15782dbbabf99ecb17ba22119cc2bd2"
    },
    "angularjs/angular-mocks.d.ts": {
      "commit": "ef32bff4d15782dbbabf99ecb17ba22119cc2bd2"
    }
  }
}

I am using IntelliJ IDEA 14

Thank you, Stefan

Answer №1

The Angular team recently made a comment regarding the global module in angular-mocks

//It is recommended to use `angular.mock.module` instead of just `module`, as there may be conflicts with commonjs.
//declare var module: (...modules: any[]) => any;

To ensure your test compiles successfully, it is necessary to use the full namespace, like angular.mock.module

For example:

beforeEach(function () {
  angular.mock.module('app');
}

Answer №2

initially:

in advance of the following code snippet:
beforeEach(function () {
  module('app');
}

subsequently:

ahead of the next block of code:
beforeEach(function () {
  angular.mock.module('app');
}

Answer №3

Here's what I think:

It seems like you have included angular-mocks.d.ts in your project, but the file angular-mocks.ts is missing.

The d.ts files only contain type definitions and not the actual code implementation. You will need both files for your project to work properly.

By the way, it looks like angular-mocks.ts only has the .js version available :)
