Missing injection for test (unkown provider) - angularjs

Question

I am trying to write unit tests for my Angular.js application but I cannot manage to inject what I need (it is not able to find a suitable provider).
Does anyone see what I missed?
Firefox 21.0 (Linux) filter staticList should convert static list object into its display value FAILED

The application:
angular.module('myApp', ['myAppFilters', 'ui.bootstrap', '$strap.directives']).
// Some other stuff
The filters:
"use strict";
angular.module('myAppFilters', []).
filter('staticList', function () {
return function (listItem) {
if (!listItem) {
return '';
}
return listItem.value;
};
});
The test:
'use strict';
describe('filter', function () {
beforeEach(angular.module('myAppFilters'));
describe('staticList', function () {
it('should convert static list object into its display value',
inject(function (staticList) {
expect(undefined).toBe('');
expect({key: 'A', value: 'B'}).toBe('B');
}));
});
});
The Karma configuration:
basePath = '../';
files = [
JASMINE,
JASMINE_ADAPTER,
'public/third-party/jquery/*.js',
'public/third-party/angular/angular.js',
'public/third-party/angular/i18n/angular-*.js',
'public/third-party/moment/moment.min.js',
'public/third-party/moment/moment-*.js',
'public/js/**/*.js',
'test/lib/**/*.js',
'test/unit/**/*.js'
];
colors = true;
autoWatch = true;
browsers = ['Firefox'];
junitReporter = {
outputFile: 'test_out/unit.xml',
suite: 'unit'
};

Answer 1

In your inject code
it('should convert static list object into its display value',
inject(function (staticList) {
expect(undefined).toBe('');
expect({key: 'A', value: 'B'}).toBe('B');
}));
replace "inject(function (staticList)" with "inject(function (staticListFilter)". This is some random convention angular is following. You can check comments on this page for more info http://docs.angularjs.org/tutorial/step_09

Answer 2

I faced similar problem, but in my case my filter name contained suffix 'Filter' which caused the same injection problem.
.filter('assetLabelFilter', function(){
return function(assets, selectedLabels){
// Implementation here
};
});
I was finally able to solve the problem by manually injecting the filter to my test
'use strict';
describe('assetLabelFilter', function() {
beforeEach(module('filters.labels'));
var asset1 = {labels: ['A']};
var asset2 = {labels: ['B']};
var asset3 = {labels: []};
var asset4 = {labels: ['A', 'B']};
var assets = [asset1, asset2, asset3, asset4];
var assetLabelFilter;
beforeEach(inject(function($filter) {
assetLabelFilter = $filter('assetLabelFilter');
}));
it('should return only assets with selected label', function() {
var selectedLabels = ['B'];
expect(assetLabelFilter(assets, selectedLabels)).toEqual([asset2, asset4]);
});
});
The nice answer above made me realize that in order to use the angular tutorial way:
it('should ', inject(function(assetLabelFilter) {
var selectedLabels = ['B'];
expect(assetLabelFilter(assets, selectedLabels)).toEqual([asset2, asset4]);
}));
The filter name can't have the suffix 'Filter' because it is magic word as mentioned in the answer above.
To demonstrate the scenario I also created a Plunker
