I have this test structure and it is working but It does not cover my requirements when I put more tests in this unit test .js file , but all related tests should go there.
WORKING:
'use strict';
describe('lessonplannerFactory unit tests', function () {
// load the service's module
// beforeEach(module('clientApp'));
// Arrange
var dateFactory = {
getVisibleDateRange: function (startDate, endDate, visibleWeekDays) {
// I do not care about the parameters, I just want to stub out the visible days with 2 stubs
var days = [ moment(new Date(2014, 0, 1)), moment(new Date(2014, 0, 2))];
return days;
}
};
// load the service's module
beforeEach(module('clientApp', function ($provide) {
$provide.value('dateFactory', dateFactory);
}));
// Arrange
var lessonPlannerFactory;
beforeEach(inject(function (_lessonPlannerFactory_) { // The underscores before/after the factory are removed by the $injector
lessonPlannerFactory = _lessonPlannerFactory_;
}));
it('creates periods by a daily rotation of n according to a given timetable for a certain timespan', inject(function (_dailyPeriodsTestDataFactory_) {
// Arrange
var testCases = _dailyPeriodsTestDataFactory_.testCases; // specific test data
// Act
// Do something with the injected lessonPlannerFactory.method1(testCases[0],..);
// Assert
}));
});
What I want is this described in my own words or pseudo code:
describe("lesson planner factory unit tests")
{
// Inject a lesson planner factory instance for each test
test1(_specificTestData1_)
{
// Arrange
var data = _specificTestData1_;
var stub1 = { } // setup specific stub
inject this specific stub into this test with $provide.value = mock // This stub is used INSIDE the method1 to stub out a factory dependency
// Act
var result = lessonPlannerFactory.method1(data,..);
// Assert
}
test2(_specificTestData2_)
{
// Arrange
var data = _specificTestData2_;
var stub2 = { } // setup specific stub
inject this specific stub into this test with $provide.value = mock // This stub is used INSIDE the method2 to stub out a factory dependency
// Act
var result = lessonPlannerFactory.method2(data,..);
// Assert
}
}
And this is what I have tried and it does not work.
I assume that assinging the stub to the $provide.value is too late at this point inside the test because the lessonPlannerFactory is injected/created before and the lessonPlannerFactory has the real stub object as dependency. Just look:
'use strict';
describe('lessonplannerFactory unit tests', function () {
// load the service's module
beforeEach(module('clientApp'));
// Arrange
var lessonPlannerFactory;
beforeEach(inject(function (_lessonPlannerFactory_) { // The underscores before/after the factory are removed by the $injector
lessonPlannerFactory = _lessonPlannerFactory_;
}));
it('creates periods by a daily rotation of n according to a given timetable for a certain timespan', inject(function (_dailyPeriodsTestDataFactory_) {
// Arrange
var testCases = _dailyPeriodsTestDataFactory_.testCases; // specific test data
// specific test stub
var dateFactory = {
getVisibleDateRange: function (startDate, endDate, visibleWeekDays) {
// I do not care about the parameters, I just want to stub out the visible days with 2 stubs
var days = [ moment(new Date(2014, 0, 1)), moment(new Date(2014, 0, 2))];
return days;
}
};
// load the stub
module('clientApp', function ($provide) {
$provide.value('dateFactory', dateFactory);
});
// Act on the testcases in a for loop
var result = lessonPlannerFactory.createPeriodsDaily(testCases[i].data1,..);
// Assert
}));
});
Thats the error I get:
TypeError: Cannot read property 'running' of undefined
at isSpecRunning (http://localhost:3000/base/app/bower_components/angular-mocks/angular-mocks.js:1924:65)
So how can I inject a stub for a service dependency NOT in the beforeEach method but INSIDE the unit test itself, because I need a specific stub!?
